Description

Glasses-type physiological sensing, wearable device and glasses structure

technical field

The present invention relates to a glasses-type physiological sensing device, a wearable device and a glasses structure with a physiological signal acquisition function, in particular to a glasses-type physiological sensing device and a wearable device for obtaining physiological signals by installing physiological sensing elements through the glasses structure. A device and a structure of glasses with a physiological signal extraction function.

Background technique

As modern people pay more and more attention to their own health conditions and demand for real-time understanding of their physiological status, wearable physiological detection devices have received more and more attention and are gradually flourishing.

One of the main purposes of wearing a wearable physiological detection device is to be able to carry out physiological detection in daily life at any time. Therefore, all kinds of wearable physiological detection devices currently seen are aimed at combining with common wearable accessories in daily life, such as watches, earphones, etc.

Another optional wearable accessory is glasses. In recent years, glasses are no longer limited to myopia patients, but have gradually become decorative accessories, which are common and frequently used accessories in ordinary people's daily life. Therefore, using glasses as a medium for continuous wearing of physiological detection devices is also a very suitable choice. It also helps to increase user acceptance.

And in view of the fact that the wearing position of the glasses structure is the head and is set on the front of the face, it can obtain more types of physiological signals compared with other wearing structures, for example, when electrodes are installed, brain signals can be obtained , electro-ocular signals, electrocardiographic signals, electromyographic signals, electrodermal signals, etc., and when the light sensor is installed, pulse wave signals and blood oxygen signals can be obtained.

However, because glasses are accessories worn on the face, they are not only quite obvious, but also easily affect the appearance of the user. Therefore, they are different from other accessories that are easier to be hidden or less likely to be noticed, such as watches Headphones, etc., when the appearance of the glasses is abrupt or does not meet the user's aesthetic requirements, the acceptance will be greatly reduced. For example, many smart glasses have been launched on the market. It is not easy to be used in daily life, so the popularity cannot be improved. Therefore, although glasses are indeed suitable for installing physiological detection devices, they are relatively rare.

Therefore, if a glasses structure can be provided, which has the function of capturing physiological signals without sacrificing the appearance, it is believed that it will be very helpful to improve the acceptance of the general public.

The structure of eyeglasses commonly seen in daily life is mainly divided into metal glasses and rubber glasses according to the materials used. Among them, there are many choices of rubber materials, such as Cellulose Acetate, Celluloid, etc. , nitrocellulose), plastic, etc., are commonly used in the production of glasses plastic materials, in these materials, generally speaking, the glasses structure made of metal material, acetate material, celluloid material can provide better texture And shape design, for example, the metal material has high plasticity and can present the visual effect of the unique texture of metal. In addition, the acetate fiber material is also a high plasticity material, with a variety of color choices, and can present the glossiness and transparency that plastic materials do not have , and can also be mixed with other materials, such as metal materials, to achieve different styles. Moreover, celluloid material has the advantages of durability, high hardness, beautiful luster, not easy to deform, and can be re-polished. It can also be used with metal Mixed use; as for the plastic material, due to its poor texture and plasticity, it is mostly used to make glasses that pursue low prices. Therefore, in the current market, glasses made of metal material, acetate fiber material and celluloid material are the most commonly used and most popular.

In addition, in terms of manufacturing process, acetate fiber and celluloid materials are completely different from plastic materials due to their own characteristics. Among them, when using acetate fiber material to make the glasses structure, various processes such as cutting, stacking, and polishing are performed from the sheet material. In addition, when the celluloid material is used, it starts from the block-shaped base material and goes through multiple manual processes. Procedures, such as cutting board, trimming, polishing, etc., before forming the glasses structure, and if you want to mix other materials, such as metal, in the glasses structure of these two materials, you will use embedding, clamping, and/or Or insert and other ways to combine with it, one can be used as a support, and two can also create different visual effects and shapes. As for the plastic material, the glasses are made by injection molding.

At present, in order to install physiological sensing elements through the glasses structure to obtain physiological signals, the first problem we face is how to install circuits in the glasses structure, because the electrical connection between the physiological sensing elements and the control circuit must be achieved in order to perform Extraction of physiological signals. In particular, the head is the only possible position to obtain EEG signals and EEG signals. Therefore, a physiological detection device in the form of glasses has the possibility of executing EEG signals and/or EEG signals. For the structure of glasses, The sampling position of these two signals is the position where the sides of the head and the middle of the eyes will touch the frame unit or the mirror feet. Therefore, in order to achieve the setting of electrodes and circuits, it can be used to set the circuit in the frame unit and mirror feet. , so, naturally, the existing method is to use plastic glasses that can be made by injection molding, so that the circuit can be wrapped in the frame unit and the mirror feet, for example, to form a hollow shell to pass through In addition, because the circuit needs to pass through the turning point, for example, the flexible circuit board is used as the load, so the junction of the mirror frame unit and the mirror foot usually needs a special design. However, as mentioned above, first of all, the texture provided by plastic materials is no longer comparable to that of acetate and celluloid materials. If further, the design of the frame part deviates from the general structural design in order to match the wiring, it will affect the wearing visual effect. The impact is great, therefore, it is difficult to be accepted by consumers in the market.

Accordingly, on the basis of the above, the applicant believes that if the glasses-type physiological detection device is to be widely accepted by ordinary consumers, it is obvious that it is necessary to adopt a structure of glasses that has been accepted and loved by the public in terms of texture and shape, rather than making the glasses-type physiological detection device widely accepted by ordinary consumers. Consumers reluctantly accept glasses with poor quality and special shapes, and it is even more advantageous if they can replace the glasses they usually use, such as vision correction glasses, sunglasses, blue light glasses, etc., so that even Physiological testing can be performed uninterrupted and naturally in daily life, which will truly realize the best meaning of wearable physiological testing.

detailed description

When glasses are worn on the face, places where they naturally come into contact include the area between the eyes, e.g., bridge of the nose, shank, etc., the sides of the head near the temples, the ears, and areas of the head near the ears, e.g., above the ears Or the rear, usually, as long as you choose a pair of glasses that suit you, the contact between these positions and the glasses can be achieved naturally without special force. Therefore, if physiological sensing elements, such as electrodes or light sensors, can be placed etc., are set at these positions, as long as the action of wearing the glasses is completed, the setting of the physiological sensing element is also equal to being completed.

As for the type of electrophysiological signals that can be obtained, there are many possibilities, for example, oculographs can be obtained simultaneously through the contact of the frame unit with the area between the eyes and the contact of the temples with the temple, the ear, and/or the area near the ear EEG signals and EEG signals; EEG signals can be obtained through the contact between the temples on both sides and the skin of the head; and EMG signals or EEG signals can also be obtained through any two contact positions separated by a certain distance. There are quite a few possibility.

Under the circumstances that the glasses have so many advantages, the present invention further achieves the needs of setting electrodes and obtaining physiological signals by using the structure of the glasses by providing the simplest and most convenient method that does not affect the appearance of the glasses, especially the appearance of the front frame unit. The concept of sampling loops to thereby increase public acceptance.

What needs to be clarified in advance is that the glasses structure described here refers to a wearing structure that is arranged on the head through the auricle and the nose as a support point and will come into contact with the skin of the head and/or ears. It is a form with or without lenses, with or without a hinge structure, and it can also be glasses for various purposes. For example, it can be general optical glasses, or sunglasses, or special glasses. Function glasses, for example, blue light glasses, virtual reality glasses (Virtual Reality Glasses, VR Glasses), augmented reality glasses (Augmented Reality Glasses, AR Glasses), and special glasses with display functions, etc. In addition, some glasses are designed to increase The fixed effect will also set a strap between the two temples. In addition, there is no limit to the contact position with the head/ears. For example, some glasses will also be implemented to touch around the eyes for actual use needs or shapes, such as VR glasses. Therefore, all other parts are possible forms, and these are the application scope of the present invention, so there is no certain limitation.

First of all, in the conception according to the first aspect of the present invention, the main focus is how to achieve the joint structure between the frame unit and the mirror pin in the general eyeglass structure without changing the joint structure between the frame unit and a mirror respectively. Conduction between electrodes on the feet or on the second mirror feet and the circuit system.

In the structure of glasses, the joint between the frame unit and the temples is a very important part of creating visual effects, and it is also one of the key points when users choose the structure of glasses. Therefore, if the structure here can not be changed, for It will help a lot in terms of maintaining the integrity of the frontal visual effect of the frame unit.

Generally speaking, no matter what kind of material is used for the glasses structure, it is a common way to achieve the joint between the mirror pin and the frame unit by using a hinge structure, so that the relative position of the mirror pin and the frame unit can be changed, so It is an indispensable component in almost all eyeglass structures, and the most common one is the metal hinge structure. As shown in FIG. The combination between the mirror feet 14, therefore, in the applicant's idea, if the metal twisted structure can be used as a part of the circuit, the electrical signal transmission between the mirror feet and the mirror frame unit can be naturally achieved.

Here, it should be clarified that the so-called metal hinge structure refers to the one that achieves the change of the position of the mirror foot relative to the mirror frame unit through at least one metal piece connected to the mirror frame unit and one metal piece connected to the mirror foot. For example, unfolding and collapsing will vary depending on the design of various eyeglass structures, but as long as the position change can be achieved, it is within the scope of the present invention. For example, as shown in Figure 2A, one of the accessories can be worn on the The form in another fitting, or the form in which the two fittings are combined with each other through an axis as shown in FIG. 2B , therefore, can be in any form without limitation. In addition, the twisted structure can also be made of other conductive materials, such as conductive rubber, conductive silica gel, etc., or it can also be implemented in the form of mixed materials, as long as the temples are unfolded, they can be formed to transmit telecommunication. The number of connections is enough, and there is no limit.

In addition, alternatively, on the premise of not changing the appearance of the junction between the frame unit and the mirror feet, other methods can also be used, for example, a pair of metal contacts can be respectively arranged on the mirror frame unit and on the mirror feet, Then an electrical connector is arranged between the two contacts, so that an electrical connection can be achieved, which is also easy to implement and does not affect the appearance; or, the metal contact and the electrical connector can also be implemented as one, that is, the One part of the electrical connector is integrated with the metal contact on the mirror frame unit, and the other part of the electrical connector is integrated with the metal contact on the mirror foot, for example, by direct casting. In this case, Then only two metal contacts need to be connected to each other; or, if the mirror feet or the mirror frame unit have been implemented to be made of metal material, at this time, the metal contacts are equivalent to being integrated in the mirror feet and/or Or in the mirror frame unit, it is only necessary to add an electrical connector. Therefore, they are all practicable modes without limitation.

The following describes how to use the metal hinge structure to endow the eyeglass structure with the function of picking up electrophysiological signals. However, it should be noted that although the following embodiments are described using a metal twisted structure, as is well known to those skilled in the art, and not as a limitation, one of the above-mentioned pair of metal contacts (and a matching The structure of electrical connection parts).

Please refer to Fig. 1, which shows a schematic diagram of a structure of glasses according to a preferred embodiment of the present invention, as shown in the figure, a structure of glasses 10 includes a frame unit 12, and two mirror pins 14, 16, wherein the frame unit and The two temples are respectively connected to each other by a metal hinge structure 18 . In addition, generally, the mirror frame unit has two nose pads 122 , 124 in the area between the two eyes.

Furthermore, in order to obtain electrophysiological signals from the user, the glasses structure will also include two electrodes. In the embodiment shown in FIG. On the single side nose pad 122, wherein, especially, the electrode 30 is implemented to be further electrically connected to the metal hinged structure 18, therefore, through such a configuration, it is only necessary to connect the metal hinged structure 18 to the 14 is used to control the circuit system 100 for signal acquisition. Such a glasses structure can be used to obtain electrophysiological signals, such as electroencephalogram signals, electrodermal signals, and/or electro-ocular signals.

In addition, alternatively, the electrode 30 can also be arranged on the frame unit near the nose pad, to contact positions such as mountain roots, or other positions that can touch the head on the frame unit, for example, around the eye socket; and alternatively, The electrode 30 can also be arranged on the other mirror leg 16 . In this case, it only needs to be connected to the metal hinged structure (not shown) of the mirror leg 16 first, and then connected to the metal hinged structure 18 , which is also feasible.

That is to say, through such a design, as long as the combination of the frame unit and the temples is a glasses structure with a metal hinge structure, the electrophysiological signal can be easily obtained without changing the structure and appearance of the joint. function, thus providing the possibility for the user to add the physiological signal acquisition function to the structure of the glasses that suits the user's choice.

Here, as is well known, as shown in FIG. 3 , the circuit system 100 will include, but not limited to, a physiological signal acquisition circuit, a processor module, an analog-to-digital converter, a filter, a battery, etc. to achieve physiological signals. The required circuits and components are extracted, and in order to extract the physiological signal, the physiological signal acquisition circuit needs to be electrically connected to the two electrodes. However, since they are well known to those skilled in the art, It will not be described in detail here. In addition, it should also be noted that the above-mentioned circuits and components can be arranged at any position of the glasses structure, as long as they are electrically connected to each other, there is no limitation.

The following describes how the electrodes, the metal strand structure, and the circuit system are interconnected.

One option is to use the conductive part of the frame unit to make the connection. For example, one common type of eyeglass structure is one that has metal parts in the frame unit, for example, where the frame unit is only formed of metal material alone, or, as shown in Figures 4A-4B, the metal part 32 in the frame unit Those who are covered with other materials, or the metal parts 32 are embedded in other materials, and the position of the metal parts in the picture frame unit also has various changes. For example, as shown in Figure 4C, only the upper half of the picture frame unit Or the lower half is formed with a metal part 32, and it is important for the present invention that in these designs, the metal part of the mirror frame unit will be connected to, or include, the metal part in the above-mentioned metal hinge structure that is connected to the mirror frame unit. Therefore, the electrodes arranged on the nose pads or other positions of the frame can be naturally connected to the metal hinge structure through the metal part of the frame unit.

Here, it should be noted that, based on differences in glasses designs and manufacturing processes, as long as the conductive part connected to the metal hinge structure is placed in the frame unit during the process of manufacturing the glasses structure, it is within the scope of the present invention. The object described is not limited in any form, for example, it may be a metal wire, or a rigid or flexible circuit board, or a metal part with a shape, or a metal part used as a frame supporting the main structure, etc., and this can be The conductive part can be implemented as being connected between two metal stranding structures, also can be only connected between a single metal stranding structure and one or two nose pads, or can also be connected simultaneously between two metal stranding structures and one or Two nose pads, both unlimited.

Another option is to use the frame unit to carry the conductive part. For example, the frame unit of one type of eyeglass structure is made of non-conductive material, for example, it is made of pure rubber material. In this case, the method of adding a conductive part can be used to achieve the same The connection of the metal strand structure, for example, the additional conductive part can be connected between two metal strand structures, and can also be connected between a metal strand structure and the nose pad, which can be changed according to different needs; as for the additional The arrangement of the conductive part can also vary according to the structure of the glasses. For example, it can be a metal wire or a metal film hidden inside the frame unit. As long as it can be connected to the design of the metal hinge structure, it is feasible.

Among the above-mentioned possibilities, it just fits the types of glasses that are most commonly used by users on the market today. One is metal glasses, and the other is acetate or celluloid glasses. Among them, metal glasses are made of The metal material is the main material, that is, the metal material is used as the supporting main structure of the glasses, and for visual effects, shape changes, etc., it is possible to set other materials outside the metal material, such as rubber materials, but generally speaking, Metal material glasses are made of metal material as a whole, including the frame unit, the mirror feet, and the hinged structure for joining the frame unit and the mirror feet.

As for glasses made of acetate fiber or celluloid, as mentioned above, in its existing manufacturing process, there have been steps of inserting metal parts into this kind of material. Put the metal parts of the mirror frame in other ways, or insert or embed the metal parts of the mirror legs, etc., and one of the purposes of this process is to strengthen the mechanical strength of the glasses structure. Therefore, it is used to put the glasses into Most of the metal parts in the structure will have a supporting role. Under such a premise, as long as the inserted metal parts are connected to the metal stranding structure, even common glasses made of acetate or celluloid can directly use the original metal parts in the glasses as Conductive part to achieve electrical connection between the electrodes and the circuit system.

And usually, when there is a metal part as a support in the mirror frame, the metal stranding structure has been directly formed on the metal part, and the metal part often has a metal extension for setting the nose pad, so , depending on the actual structure, such a frame unit with metal parts already has the metal hinge structure at one end to the metal hinge structure at the other end, or the metal hinge structure at one end to the nose pad ability (only need to replace the conductive nose pad), that is, such a frame unit can be directly used for physiological detection, without having to process on the frame unit in order to achieve electrical connection, so that the general consumption The glasses used by the patient in daily life can be used to obtain physiological signals, which completely subverts the existing concept of the current physiological detection device based on glasses.

Therefore, it can be seen from the above that, through the concept of the present invention, the two most widely accepted glasses on the market can realize the connection between the electrodes arranged on the frame unit and the metal hinge structure without changing the front appearance. electrical connection.

Still further, after the electrodes in the mirror frame unit have been connected to the metal hinge structure on one side, the metal hinge structure needs to be connected to the circuit system arranged on the mirror feet.

One option is to use conductive parts in the temples to make the connection. For example, as mentioned earlier, the temples of metal glasses will directly use metal parts, and metal parts are often inserted or embedded in the temples of acetate or celluloid glasses as supports or shape changes, and as long as these designs The metal part of the middle temple is implemented to be connected to, or includes, the metal part connected to the temple in the above-mentioned metal hinge structure, and then the metal hinge structure can be naturally connected to the circuit system on the temple.

Here, it should be noted that, based on the differences in glasses design and manufacturing process, as long as the conductive part connected to the metal hinge structure is placed in the temple during the process of manufacturing the glasses structure, it is within the scope of the present invention. The object described is not limited in any form, for example, it may be a metal wire, or a rigid or flexible circuit board, or it may be a shaped metal temple, or a metal component used as a support, etc., and there is no limitation.

Another option is to use the temples to carry the conductive part. For example, the temples of one type of glasses structure are made of non-conductive materials, for example, those made of pure rubber materials. In this case, the metal can be achieved by adding conductive parts. The connection between the hinged structure and the electrodes and the circuit system; as for the arrangement of the additional conductive part, it can also be changed according to the structure of the glasses. For example, it can be a metal wire or a metal film hidden inside the temple. The connection between the metal strand structure and the circuit system located on the mirror feet is sufficient, without limitation.

Here, in particular, due to the use of a metal hinge structure to join the relationship between the mirror frame unit and the mirror feet, the mirror feet can be replaced. Therefore, in this case, it can be implemented to obtain Connections to metal strand structures, electrodes, and circuitry, and this approach is particularly beneficial for eyeglass structures that already have conductive parts in the frontal frame unit, as shown in Figure 3D, in which the The nose pads 122, 124 have been formed into metal materials, and the frame unit has already included the metal parts 32 connected between the two metal hinge structures 18 and connected to the nose pads. Therefore, at this time, as long as the temples are replaced, For example, if an electrode is arranged on the surface of the temple, and a new temple is provided with a circuit system and a circuit connected to the electrode and the metal temple structure in the temple, the original common eyeglass structure can be immediately obtained. The physiological signal acquisition function, and, importantly, because compared with the frame unit located on the front of the face, the temple is a less obvious part when wearing, so the shape effect of the glasses will not be affected, and then In addition, the temples do not involve the most important function of the glasses—the lens setting, so it is definitely a very advantageous way.

Furthermore, in addition to placing the electrodes on the nose pads and temples on one side, the electrodes can also be placed on the temples on both sides, or the number of electrodes can be increased, and electrodes can be placed on the nose pads and temples on both sides. , can also obtain EEG signals and/or oculoelectric signals, wherein, when electrodes are provided on both sides of the temples, it is necessary to use two metal strand structures to achieve the connection between the electrodes and the circuit system, that is, Both the mirror frame unit and the mirror feet on both sides must have conductive parts connected to the metal hinge structure. In addition, the circuit system can be selectively set only on one side of the mirror feet, or also scattered on both sides of the mirror feet. Among them , when the circuit system is scattered on both sides of the temples, the conductive part of each side of the temples must achieve the connection between the side metal hinge structure and the side circuit system, and in this case, as mentioned above, Of course, it can also be implemented as a mode in which both temples are replaced.

Moreover, in addition to the above-mentioned setting options, the electrodes can also be set in other ways to obtain other physiological signals. For example, electrodes that can be touched by the user's upper limbs can be set on the temples. In this way, Then, the electrodes contacting the head and the electrodes contacting the upper extremities can be used to obtain ECG signals. Here, especially, the electrode for upper extremities can not only be set separately, but also can be shared with the EEG electrodes. For example, it can be formed by extending the electrodes on the inner side of the temples, or the EEG electrodes can be directly formed and arranged on the inner side and the outer side as a continuous surface, and can be implemented in parallel or in series with one of the EEG electrodes. , and because the amplitude difference between the EEG signal and the ECG signal is obvious, even if it is shared, it will not affect the judgment of the signal.

Alternatively, electrodes can also be added on the temples, for example, two electrodes spaced apart from each other, for example, one inch apart, can be set on one side of the temples, so as to additionally obtain electrodermal signals. On the other hand, such two electrodes It is also possible to obtain local myoelectric signals, electroencephalogram signals, and oculoelectric signals near the electrodes; or, further, optical sensors can also be set on the temples or frames to obtain blood physiological signals from the head, for example, pulse wave signal, blood oxygen concentration, etc.; or a motion sensing element, such as an accelerometer, a gyroscope, or a magnetic sensor, can also be installed to obtain the user's body movement information. Therefore, various options are possible without limitation.

Among them, a special embodiment is that, according to the applicant's research results, electrodes can be arranged on the glasses structure to obtain orbitofrontal cortex (orbitofrontal cortex) activity, and then obtain EEG signals. The orbitofrontal cortex is a part of the prefrontal cortex. Its position is lower and close to the orbit. Therefore, when electrodes are placed on the nose pads or the upper edge of the frame unit, its activity can be detected. On the other hand, Since the electrodes such as the nose pads and the upper edge of the spectacle frame unit are also located close to the eyes, the electro-oculogram signals can also be obtained with such electrode settings.

In this case, when paired with another electrode, for example, on one side of the temple, on the frame unit, or extended on the ear, mixed orbitofrontal cortex activity and eye movement can be achieved The electrophysiological signal of the electrophysiological signal, and because the signal strength and signal characteristics of the oculoelectric signal and the EEG signal have a certain degree of difference, therefore, as long as the electrophysiological signal is processed, for example, the oculoelectric signal is removed, the orbital EEG signals from the frontal cortex.

Since the activity of the cerebral cortex tends to be synchronized, the EEG signal of the orbitofrontal cortex can be used as a reference for judging the state of brain consciousness.

Generally speaking, there are two ways to measure brain electrical activity, the reference montage and the bipolar montage. In the reference combination paradigm, it is common to place the reference electrode at a location where there is no electrical activity in the cerebral cortex, and the activity detection electrode is placed at the skull position above the corresponding specific cerebral cortex to obtain brain waves relative to the reference electrode, Furthermore, the activities of the local cerebral cortex can be known. As for the bipolar combination paradigm, the brain waves are obtained through the difference in the electrical activity potential of the brain at two locations. Therefore, usually, the combination paradigm to be adopted is determined according to different needs. In addition, no matter what kind of combination paradigm, a ground electrode (Ground) is often set to eliminate background noise, such as electromagnetic interference, but there are also some circuit designs that can be exempted from setting the ground electrode, which can be selected according to actual needs, so in the present invention In the description, the placement of the electrodes is mainly based on the two electrodes used to obtain brain waves.

Therefore, when the electrodes are carried in the structure of glasses, for example, two electrodes respectively contacting the two sides of the head, or two electrodes respectively contacting the bridge of the nose and one side of the head, can be regarded as a bipolar combination paradigm.

In addition to the generally conceivable electrode contact positions on the skull, the applicant has found through research that there are other contact positions that are also suitable for obtaining electrophysiological signals, especially EEG signals.

Please refer to Figure 5A, which is a schematic diagram of the position of the cerebral cortex in the skull and the position of the auricle. It can be seen from the figure that the cerebral cortex falls on the upper half of the skull, and the auricle (also called pinna) is It is located on both sides of the skull and protrudes outside the skull, wherein, roughly speaking, it is separated by the ear canal, and the cerebral cortex falls roughly on the inner side of the upper ear canal. The applicant found after experiments that good EEG signals can be measured at the upper part of the auricle, and the lower the EEG signal is, the weaker it is. After observing the physiological structure of the head, it should be because the upper auricle The corresponding inside of the skull is the position of the cerebral cortex. Therefore, in this case, through the transmission of the skull and ear cartilage, brain waves can be measured at the upper part of the auricle, while the lower part of the auricle is farther away from the cerebral cortex. , plus the interval of the ear canal, therefore, the strength of the EEG signal becomes weaker as it goes down. For example, positions such as the tragus, antitragus, and intertragic notch, due to their physiological structure, also belong to the part of the auricle that protrudes outside the skull, and there is no The cerebral cortex, therefore, is a suitable location for setting the reference electrode.

When wearing glasses, the nose pad will touch the bridge of the nose, the root of the mountain, and/or the area between the eyes, the front part of the temples will touch the temples, and the back part of the temples will touch the V-shaped depression between the auricle and the skull. area, and the part of the spectacle feet behind the auricle will touch the skin behind the auricle, the mastoid bone, etc., where the V-shaped depression and the back of the auricle are just in line with the above-mentioned position on the ear where EEG signals can be obtained. Therefore, Unlike the general concept that the EEG electrodes need to be placed on the skull with the cerebral cortex, the applicant found that even if the electrodes are placed on the auricle, the EEG signals can also be obtained, and therefore it is more suitable to be set by the glasses structure In particular, the general V-shaped depression is the position where the temples are erected, and the back of the auricle can be contacted by increasing the curvature of the end of the temples, which is quite advantageous in implementation.

As shown in Figure 5B, the V-shaped depression is located between the auricle and the skull, which includes a skull part 501, an auricle part 502, and a connecting part 503 as a connection, thus forming a structure that is just suitable for placing objects between the auricle and the skull. In this case, the auricle and the skull will naturally provide the force to sandwich the object in between, and even, when the object is of sufficient size and/or shape, the object can be embedded/plugged in the ear between the outline and the skull to achieve a better fixation effect. However, it should be noted here that since the junction between the auricle and the skull is a continuous curve, there is no specific range limit for the V-shaped depression, as long as the temple is set on the auricle, its structure can The range of contact is within the scope of the V-shaped depressions referred to in this application. For example, when the bending range of the end of the temple is just in line, the range of the V-shaped depression is larger, or there are also mirrors with no bending at the end. At this time, the range of the V-shaped depression is relatively small, so there is no limitation.

And when the temples are placed in this area, they can selectively contact any part of the three parts 501-503. However, since the object will be subject to gravity, generally speaking, the connecting part 503 located below is the most accessible position. Furthermore, according to the different habits of each user wearing glasses, the contact with the skull part 501 and/or the auricle part 502 may be increased, and no matter what the situation is, as long as the glasses that are suitable for oneself are selected, the The contacts can be quite stable, so that physiological signals can be obtained easily.

However, in particular, as long as the position of the electrodes is designed, the EEG signals can also be obtained by using the reference combination paradigm, for example, an electrode is set on the bridge of the nose, or a position on the side of the temple that contacts the skull part 501, and another The electrode is set on the other side of the temple at the position where it contacts the auricle part 502 as a reference electrode. At this time, compared with the nose bridge or the skull part with the cerebral cortex below, the auricle part will have relatively low cerebral cortex activity Therefore, EEG and/or EEG signals can be obtained using the reference combination paradigm; alternatively, both electrodes can be placed on the temple on the same side, and one electrode can be used to touch the lower part of the back of the auricle away from the cerebral cortex As a reference electrode, the other electrode only needs to touch the top of the back of the auricle, the V-shaped depression, or the side of the head and other positions close to the cerebral cortex, and the EEG signal can also be obtained by using the reference combination paradigm.

Therefore, when the glasses structure is used to carry the EEG electrodes according to the present invention, the obtained EEG signals are not limited by which combination paradigm is obtained, and both combination paradigms are feasible.

Furthermore, in order to allow the electrodes disposed on the surface of the mirror feet to have good contact at the V-shaped recessed position, it can also be achieved by designing the structure of the mirror feet and matching the location of the electrodes. For example, as shown in FIG. 6A, when the cross-sectional structure of the mirror feet is implemented as a similar square structure, the electrode 20 can be arranged on the lower surface of the square, so as to naturally contact the connecting part of the V-shaped depression due to gravity. Or, as shown in Figure 6B, this mirror foot also can be formed into the similar D-type structure, like this, by being arranged on the curved surface of D-type structure by electrode 20, just provide the connection that allows electrode contact V-type depression part 503 and the cranial part 501; or, as mentioned above, when it is desired to serve as a reference electrode, the electrode can be set at a position in contact with the cranial part 501; The probability of contact between the electrode and the three parts is increased, therefore, various options can be provided, which can be changed according to actual needs.

Similarly, the light sensor is also suitable to be disposed in the above-mentioned V-shaped recessed position. Generally speaking, the location of the optical sensor can be any position where the structure of the glasses contacts the head, for example, the contact between the nose pad and the area between the eyes, the bridge of the nose, the root of the mountain, etc., or the contact between the temples and the side of the head, ears, etc. and/or the area near the ear, and wherein the particularly advantageous contact position is the V-shaped depression between the ear and the skull, and, based on the influence of gravity, the setting of the connecting part 503 is the most stable. However, due to the light The physiological signal obtained by the sensor has less restrictions on the sampling position, usually it only needs to detect the position where the blood flow changes, so whether it is the connecting part 503, the head part 501, or the auricle part 502 The position of the light sensor can be set without limitation.

On the other hand, since the glasses are implemented as a wearable form, how to maintain effective contact between the electrodes disposed on the surface and the skin while wearing them easily will be the key to the success of the wearable form. Regarding this point, the present invention further adds a contact ensuring structure on the electrode to overcome the contact problems that may be encountered when wearing glasses, such as hair covering, contact surface bending, and possible displacement with body movement. And the contact position is different due to individual differences.

In addition, another problem that may be encountered is that since the distance from the front of the head to the ears is different for each person, how can the structure of the glasses be worn on the heads of different users? Contact locations where the electrodes can still make contact with the target, eg, hairless locations near the top of the ear, at the junction between the ear and the skull, etc., are also considerations.

The contact ensuring structure can have various implementation possibilities. For example, as shown in FIG. When the point is touched, it can be regarded as the contact between the electrode and the skin has been completed, which is quite convenient, and this is especially suitable for setting on a curved contact surface, or in situations where slight movement may occur, or to overcome different uses differences in the distance between the head and ears of the recipient, and further advantageously, the individual discrete contact points can be implemented to be scalable, for example, in the form of pogo pins as shown in Figure 7B, to further ensure The contact can be achieved, for example, by compressing the spring thimble between the skin and the electrode. In this way, even if there is a small displacement between the skin and the electrode, it can be achieved through the stretching elasticity of the spring thimble. be overcome.

In addition, as shown in Figures 7C-7D, it can also be implemented in the form of having multiple protrusions on the same electrode part 23, for example, the electrode sheet can be directly formed to have multiple protrusions (Figure 7C), or, It can be implemented as a plurality of stretchable protrusions in the electrode sheet (FIG. 7D), etc., and can be in various forms, which also helps to increase the contact between the skin and the electrodes.

Furthermore, the electrodes can also be implemented in a suspended form. For example, as shown in FIG. 7E, a telescopic structure, such as a spring thimble, is arranged under the electrodes. In this way, to adapt to the change of the contact surface, the electrodes can have vertical direction In addition to expansion and contraction, the lower spring thimble can also be used as a fulcrum to change the angle, which is quite helpful for adapting to the shape of the contact position; and further, protrusions can also be formed on the surface of the electrode in the form of suspension, for example, combined with Implementing Figures 7C-7D and Figure 7E makes contacting easier.

Here, it should be noted that the above-mentioned contact ensuring structure can be implemented in any position of the glasses structure, for example, it can be in contact with the bridge of the nose, behind the ear, above the ear, behind the head, etc., which are all feasible and not limited.

In addition to the above method, there is a simpler implementation method for contacting the junction between the ear and the skull, as shown in Figure 7F, in this preferred embodiment, the electrodes 20 on the temples are formed It is a long-shaped electrode distributed in a wide range. In this way, the possible size differences between different users can be covered. Even a single glasses size can be adapted to different users. This is very important for production. , is a very favorable choice.

As for the distribution range of the elongated electrodes, there is no certain limit, and can be changed according to different actual needs, wherein, preferably, it is formed to a length greater than 2 centimeters, for example, a length greater than 2 cm is set on the mirror feet. A 2 cm stainless steel sheet is used as an electrode; in addition, this large-scale distribution can also be achieved by the above-mentioned contact ensuring structure, for example, expanding the distribution range of multiple protrusions, telescopic structures, or setting protrusions on the entire electrode, or The entire electrode has multiple suspension support points, etc., to further increase the stability of the contact.

In another preferred embodiment, the electrodes are implemented in a form that can move on the temples. In this way, when worn on the heads of different users, the electrodes can be adapted to the differences in the size of each person. Position adjustment to accurately touch the desired position is also a very advantageous option.

During implementation, as shown in FIGS. 7G-7J , the ear contact portion on the temples of the glasses, which is used to set the electrodes, is implemented with an adjustment mechanism 22, so that the position of the electrodes on the temples can be changed. In this way, the position where the physiological signal is to be obtained can be accurately aligned, for example, the hairless position at the junction of the ear and the skull. In addition, the ear contact part can be further implemented to conform to the curve of the back of the pinna for more stable The setting also helps the physiological sensing element arranged on it to carry out signal acquisition.

Wherein, Fig. 7G shows that the ear contact part is directly implemented as a part of the temple, and Fig. 7H shows that the ear contact part is implemented in a form combined with the temple, and further has a curve that conforms to the back of the auricle. As for the adjustment The mechanism has many implementation options. For example, it can be implemented as a sliding mechanism. For example, a track is set, as shown in FIG. Stepless movement, without limitation; it can also be implemented as a clamping/erection mechanism, as shown in Figure 7I, or a sleeve mechanism, so as to achieve the effect of being able to move along the temple; it can also be implemented as a magnetic attraction mechanism, for example, The temple and the electrode/combining module are implemented to be magnetically attracted to each other, so as long as the electrodes are within the range of the magnetic force, all the electrodes can be placed, and the effect of moving along the temple can also be achieved. In addition, in terms of production, a simpler implementation is that, as shown in Figure 7J, multiple bonding positions can be set on the surface of the temple facing the head, for example, it can be implemented as a card slot to place the implementation Electrodes with a corresponding structure are fixed by mechanical snapping, so that when in use, users can choose where to combine them according to their own head size or different detection position requirements. One joint location is likewise quite convenient, or, alternatively, it can also be implemented as several magnetically fixable locations, which is also quite advantageous. Therefore, various possibilities are possible without certain limitations.

It should be noted here that the above-mentioned arrangement methods are also suitable for setting other physiological sensing elements that also have location requirements. For example, the light sensor also needs to be arranged in a place without hair, so there is no implementation limitation.

Still further, besides being directly arranged on the surface of the mirror frame unit and/or the mirror feet, the electrodes and light sensors can also be arranged externally, for example, by directly combining with the mirror feet, or by No matter how you set it up, the key point is that it needs to be connected to the conductive part in the frame unit and/or mirror feet, so that it can be connected to the metal hinge structure and/or circuit system, and then carry out physiological signals of the capture.

On the other hand, in addition to being arranged in the mirror feet as shown in Figure 1, the circuit system can also be implemented as a combination module combined with the mirror feet. For example, all circuits are arranged in the combination module , or, only part of the circuit is set in the combination module, etc., are all feasible ways without limitation, and in the following embodiments, for the convenience of description, all circuit system components are included in the combination module as an example. The descriptions and illustrations are given by way of example only and not by way of limitation, as is well known to those skilled in the art.

First of all, when it is implemented in the form of a combination module, it means that the combination module can be combined with or removed from the mirror feet according to needs, allowing users to decide whether to connect or not according to their own needs. The module also provides the possibility of reducing the wearing burden when physiological signal acquisition is not required.

Furthermore, when the combination module is combined with the mirror pin, no matter what the combination method is, the most important thing is to achieve a connection with the conductive part of the mirror pin, that is, the conductive part of the mirror pin needs to expose the contact position , and the binding module needs to be provided with corresponding electrical contact positions to achieve electrical connection while combining, so that it can be connected to the electrode, and if necessary, connected to the metal strand structure, and achieve the electrophysiological signal sampling loop.

On this premise, there are many options for combining the combining module and the temples. For example, as shown in FIG. 8A, the combination module 40 can be connected with a port, so as to use the hardware structure of the port itself to achieve the connection, on the one hand to achieve electrical connection, and on the other hand to provide fixing force; or, alternatively, also As shown in FIG. 8B , the combining module 40 can be implemented in a form that is sheathed at the end of the mirror pin. Although such a design will increase the volume of the end of the mirror pin, it can just allow the module to be hidden. For example, it can just be hidden in the Behind the ears, or covered by hair, it is still quite advantageous; in addition, other combinations can also be used, for example, as shown in Figure 8C, the combination module can be implemented as a longer shape and the temples can be embedded Set in it, or use the way of wearing, etc. Therefore, the shape and combination mode of the combination module can be determined according to the shape of different temples. Moreover, the number of combination modules is not limited, and can be implemented in multiples according to requirements. For example, two combination modules are set on one side of the temple at the same time, or one combination module is set on each side of the mirror feet, or a combination module is installed on the mirror frame. It is also a possible option to arrange another binding module at the area between the eyes of the unit.

Furthermore, the combination module can also be implemented to be connected to the mirror pin through a connecting wire. For example, an electrical port 42 can be formed at the end of the mirror pin for the connection of the combination module. In this case, the connection module's There are more changes in the implementation form. For example, the combination module can be implemented in the form of an ear-wearing structure, for example, in the form of an in-ear shell (FIG. 8D), or in the form of an ear clip, etc., to provide stability. In addition, since the ear is also the position where EEG signals can be obtained, it is also possible to set electrodes on the ear-wearing structure, for example, the position where the ear shell contacts the inner surface of the auricle, the ear canal, or the ear A reference electrode is set at the position where the clip is in contact with the earlobe to obtain EEG signals and/or electro-oculogram signals together with the electrodes of the glasses structure; or, as mentioned above, the position of the upper half of the auricle above the ear canal, for example, the concha Wall (inside the pinna, around the superior concha and inferior concha cavity, from the concha floor (that is, parallel to the plane of the skull) upward to the antihelix ) and an elevational area of the antitragus, known as the concha wall), which serve as locations for activity detection electrodes, as well as the lower half of the pinna below the ear canal, e.g. Screen, antitragus, intertragus notch, etc., can be used as the position for setting reference electrodes. Furthermore, the use of ear-worn forms also increases the possibility of providing information through sound. For example, sound-generating components can be provided in the ear-worn structure, or directly implemented in the form of earphones, to inform users of their current physiological conditions through sound.

Or, as shown in FIG. 8E , the combination module can be arranged behind the head by combining with the temples on both sides. For example, one side is electrically connected to the electrical port 42, while the other side is simply mechanically combined as a fixation. Or both sides are implemented as electrical ports; in addition, in addition to using electrical ports, the electrical connection can also be achieved in the form of electrical contact, for example, the electrical contact can be completed at the same time as the sleeve is installed, or the method of magnetic electrical contact can be used, etc. , so there are various possibilities.

Here, it should be noted that FIGS. 8A-8E only show the possible implementation of the joint module, so the electrodes and the circuit system are not drawn, so they are applicable to any kind of glasses structures and electrode/circuit configurations.

On the other hand, besides being used to arrange the circuit system, the combining module can also be used to arrange the electrodes. For example, the electrodes can be arranged on the surface of the combining module, so that the electrodes can also be provided when the combining module is combined to the temples. On the structure of the glasses, as shown in FIG. 8 , there is an electrode 50 on the inner surface of the combination module 40 , so when the combination module 40 is connected to the metal part of the temple 14 , the electrode 50 can be connected with the electrode 30 together. Obtaining EEG signals and/or electro-oculogram signals is a very convenient option; alternatively, the combination module can also have electrodes (not shown) on the outside, which are used to contact an upper limb, and then obtain ECG signals together with the electrodes 30; In addition, optical sensors can also be provided through the combination module, for example, placed on the surface contacting the V-shaped depression, so that blood physiological signals can be obtained from the head, or placed on the outside to obtain from the contacted upper limbs Blood physiological signals are also a convenient choice. Here, similarly, when the electrodes are disposed on the surface of the bonding module, a contact ensuring structure can also be used to make the contact more reliable.

Furthermore, in addition to the above-mentioned situations, there are other implementation options for the electrodes on the bonding module. For example, if the glasses already have at least two electrodes that can obtain EEG signals, electro-ocular signals, and/or electrodermal signals, for example, the two electrodes are placed on the two temples separately, and the two electrodes are located On the temples, or one electrode on the temples and one electrode on the frame unit, it can be implemented to change the location and combination paradigm of picking up electrophysiological signals by combining the combination module. Here, the setting position of the combining module may be on the mirror feet or on the frame unit, without limitation.

In one case, the electrodes on the combination module are implemented to replace one of the original electrodes on the glasses, for example, a circuit switch can be performed due to the detection of the connection of the combination module, or when the combination module is inserted, the connector ( For example, the mechanical structure of the phone jack (Phone Jack) that can switch the conduction path is used to complete the circuit switching, and through the substitution method, on the one hand, the sampling position of the electrode can be changed, and on the other hand, the combination paradigm of sampling can be changed.

For example, in terms of changing the position of the electrodes, in the example where the electrodes are separated into two temples, the electrodes on the combined module can make the electrodes that are originally set on the temples and contact the scalp of the temporal lobe area of the cerebral cortex be changed to An electrode extended backward to touch the scalp in the occipital cortex, or an electrode extended upward to touch the scalp in the parietal cortex, or changed so that both electrodes are on the same side of the head, or changed to touch one side of the head and Contacts the area between the eyes; on the other hand, in cases where both electrodes are on the same temple, combining electrodes on the module can change one of the electrodes to be on the other temple, or change contact on the same side of the head The position, for example, changes from touching the temple and the V-shaped depression to touching the V-shaped depression and the mastoid bone, or changing to touching the side of the head and touching the area between the eyes; on the other hand, when an electrode is on the frame and a In the example where the electrodes are located on the temples, the electrodes on the combination module can be used to replace the electrodes contacting the two eye areas, so that the two electrodes contact the two sides of the head respectively, or the two electrodes contact the same side of the head.

In terms of changing the sampling combination paradigm, it can be changed from a bipolar combination paradigm to a reference combination paradigm, or vice versa, for example, by contacting the mastoid bone with electrodes on the bonding module, or contacting the ear in an ear-worn form. The inner surface of the contour/ear canal can change the original bipolar combination paradigm to the reference combination paradigm. On the contrary, by setting the combination module at the head position that can correspond to the cerebral cortex, for example, the side is close to the V-shaped depression, the position of the temple , or the position where the front of the frame unit touches the area between the eyes, etc., can be used to replace the reference electrode in the original reference combination paradigm, and then use the bipolar combination paradigm to obtain EEG signals.

Another situation is to increase the electrodes used for sampling by combining modules. In addition to changing the sampling combination paradigm, the single-channel sampling circuit can also be increased into a dual-channel sampling circuit due to the addition of electrodes on the combination module. . For example, in one embodiment, if the EEG signals are originally obtained by using the electrodes arranged on the two temples, or separately on the temples and the mirror frame, using the bipolar combination paradigm, after combining the upper joint module , the electrode on it can be used as a reference electrode, for example, implemented as an ear clip contacting the earlobe, implementing as an ear shell contacting the inner surface of the auricle/ear canal, or connecting to the end of the temple to contact the mastoid bone, etc., to use the reference Combining paradigms to obtain EEG signals, for example, the original two electrodes can be combined with the electrodes on the combination module to obtain EEG signals using the reference combination paradigm, or one of the electrodes can be obtained in addition to the original sampling circuit to obtain a bipolar group In addition to the normal EEG signal, another sampling loop is formed with the electrodes on the combination module to obtain the reference combined paradigm EEG signal. In any case, the original single-channel EEG signal acquisition is changed to a dual-channel EEG signal. Extraction of electrical signals.

Alternatively, it is also possible that the original two electrodes use the reference combination paradigm to obtain EEG signals. After the combination module is combined, the electrodes on it and the original reference electrodes form another sampling loop to utilize the reference combination Paradigm to obtain EEG signals, or the electrodes on it and the original activity detection electrodes form another sampling loop, so as to obtain EEG signals by using the bipolar combination paradigm, and similarly, no matter what the situation is, it is From the original single-channel EEG signal acquisition to dual-channel EEG signal acquisition.

In another case, the electrodes on the combined module are used to increase the types of signals to be captured. For example, in addition to the original EEG signals, electro-oculogram signals, electrocardiogram signals, skin electro-signals, and/or muscle signals can be added. Telegram etc.

Therefore, by combining modules, in addition to being able to accommodate the circuit system to simplify the difficulty of making glasses, it can also be used to change electrode settings, sampling combination paradigms, and types of physiological signals to be captured, thereby increasing the flexibility of use and benefiting users. It is quite an advantageous choice.

In addition, in a special embodiment, when the nose pad of the eyeglass structure is implemented in a replaceable form (whether the eyeglass structure is combined with a combination module or not), the original non-conductive nose pad can also be replaced by a conductive nose pad. method, or vice versa, to change the sampling position, sampling combination paradigm, sampling signal type, etc. Among them, there are also two options of replacing one of the original electrodes, or performing signal acquisition together with the original electrodes. Changes between reference combined paradigms and bipolar combined paradigms, and between single-channel sampling loops and dual-channel sampling loops. However, it should be noted here that the premise is that the position of the nose pad must have been electrically connected to the circuit system, whether it is through a metal part disposed in the frame unit or by means of a wire.

Further, the circuit system may also include other functions in addition to the function of performing physiological signal acquisition. For example, the circuit system may include an information providing unit to provide physiological information, operation information, and/or other information to the user, and since the glasses are worn on the head, they are not only close to the eyes and ears, but also connected to the The skin is close to each other. Therefore, information can be provided through various means such as vision, hearing, and touch. For example, as shown in FIG. The light guide column can be extended from the inside to the lens to produce a color change, or the lens of the spectacle can be used as a display screen, for example, by means of projection, or a display element 46 is extended from the spectacle structure as shown in FIG. In front of the eyes of the user, or as shown in Figure 10C, a display unit 48 can be added to the glasses structure and placed in front of the eyes of the user. Therefore, it can be in any form without limitation; in addition, sounds can also be generated near the ears, for example, Sound-generating elements can be set on the temples near the ears, wherein the sound-generating elements used can be not only the common air conduction form, but also the bone conduction form, for example, it can be directly at the position where the temples are in contact with the skull A bone conduction speaker can be provided, or an earphone can also be extended from the glasses structure, which is especially suitable for the above-mentioned situation where the combination module is implemented as an ear-worn structure; moreover, it can also be achieved by generating vibrations at the position in contact with the skin For example, a vibration module is provided to provide physiological information, therefore, there are various possibilities.

Moreover, the circuit system may also include an operation interface, which is arranged on the glasses structure, or extends from the glasses structure, for the user to use as a control, for example, buttons, touch buttons arranged on the temples. Control interfaces, etc., or buttons and touch interfaces on the extended earwear structure, there is no limit.

In addition, the circuit system may also include a communication module to transmit physiological information to an external device in a wired or wireless manner. For example, the wired transmission method may be connected through USB, and the wireless transmission method may be connected through Bluetooth. There is no limit. The physiological information is provided to the user by an external device, for example, displaying data, waveforms, etc. on the screen, or flashing lights, vibrating, making sounds, etc.; wherein, the transmitted physiological information can be the extracted physiological signal, or it can be It is the result obtained after the analysis by the processor, which can be different according to the requirements. Accordingly, the circuit system can still have a memory to record the physiological information, and then transmit it after the detection is completed, or it can also use real-time There is no limit to the way of wireless transmission, or the use of memory as buffer storage before real-time transmission.

Here, the external device may be any device capable of transmitting and executing corresponding application programs, such as, but not limited to, smart phones, smart watches, smart glasses, tablet computers, notebook computers, and personal computers.

On the other hand, it can also be implemented to control the operation of the circuit system by the application program executed on the external device. For example, the user can always combine the combination module with the glasses, or replace the temples, but do not perform physiological signals first. Capture, when necessary, activate the application program on the mobile phone, and monitor the physiological condition in real time through the mobile phone; moreover, as mentioned above, since it is possible to obtain multiple physiological signals at the same time, it can also be obtained through an external device It is very convenient to select the type of physiological signal to be obtained and/or the type of physiological signal to be analyzed through the application program executed on the glasses. In addition, through the above-mentioned operation interface, the glasses structure can also transmit instructions to the external device, are all possible implementations.

And further, under the situation that can communicate with this external device, then the sound-generating element (air conduction type or bone conduction type) on this glasses structure can also be used for playing the music from this external device, of course, this glasses structure The internal memory can also be used to store music, such as mp3, to play directly. In addition, if a radio element is provided at the same time, the glasses structure can be used as a hands-free receiver for the external device for talking, which is quite convenient. Furthermore, The display element/display unit can be used to play video (stored in the internal memory or from an external device), all of which can be implemented.

Here, in particular, the information providing unit can be arranged on one side of the temple, and then cooperate with the physiological information obtained by the physiological sensing element installed on the glasses to convey the physiological information to the user, for example, through There are many different options for how the physiological information is transmitted to the information providing unit in the above-mentioned ways of hearing, vision, touch, etc., for example, it can be transmitted wirelessly, for example, it can be implemented as Physiological signal acquisition unit, while the temple on the other side is an information providing unit, and the two communicate wirelessly, or the two communicate wirelessly through an external device; , or through an external wired electrical connection, for example, by setting a removable electrical connection line between the two mirror feet, which are all feasible ways.

In a special embodiment, the physiological signal acquisition unit and the information providing unit are each implemented with a processor module, a communication module, a battery, etc., can operate independently, and are respectively arranged on the user's head through different temples. Afterwards, through the communication between the two, as mentioned above, wired or wireless communication, the physiological signal acquisition unit can use the information providing unit to provide physiological information to the user, wherein the physiological signal acquisition The unit can be fully or partially embedded in the mirror feet, or combined with the mirror feet by using a combination module. The information providing unit can be completely or partially embedded in the mirror feet, erected on the mirror feet, or implemented as a connection The one-ear structure up to the mirror feet is a feasible method without limitation.

The physiological sensing element of the physiological signal acquisition unit can be in various forms, such as electrodes and/or light sensors, to obtain electrophysiological signals and/or blood physiological information, and the physiological sensing element does not Limited to only one side of the temple, it can also be used to obtain physiological signals with physiological sensing elements arranged on the mirror frame or on the other side of the temple. For example, it can be implemented that both electrodes are placed on the On the temple where the physiological signal extraction unit is located, or there is only one electrode, and the other electrode is arranged on the mirror frame or the other temple.

Through such independent operation, users are provided with higher convenience of use. For example, only by changing the temples can the obtained physiological detection function and/or information provision method be changed. Purpose, for example, the mirror feet originally used to detect EEG signals can be replaced to measure ECG signals, the mirror feet that originally provided visual information can be replaced with auditory information, or other functions can be added to the original functions, etc. It has become quite simple, and even if electrodes are provided on the temples where the physiological signal acquisition unit is not located, the electrodes can be removed or become unusable by replacing the temples. The electrodes, etc., are not limited.

Furthermore, in particular, the glasses structure according to the concept of the present invention is also suitable for implementation as virtual reality glasses (Virtual Reality Glasses, VR Glasses) or augmented reality glasses (Augmented Reality Glasses, AR Glasses). It can directly provide information to users through the original information providing interface of VR and AR glasses. On the other hand, relatively, through the physiological signal acquisition unit installed on the glasses, it can also help The program judges the user's usage situation and complements each other, which is quite advantageous.

Next, in the conception of another aspect of the present invention, another possible implementation manner of obtaining physiological signals without changing the appearance of the spectacle frame unit is provided. Please refer to FIG. 11A, which shows a schematic diagram according to a preferred embodiment of the present invention. As shown in the figure, the inner side of the temple has two electrodes at the same time, one is located near the side of the eye, the electrode 62 of the temple, and the other is located at the temple. Electrodes 64 near the top of the ear.

Here, such electrode allocation positions have special significance, because the electrodes placed on the side of the eyes and near the temples can not only measure EEG signals, but also detect eye movements. Therefore, in conjunction with the electrodes near the ears After the electrode, the EEG signal and the electro-oculogram signal can be obtained at the same time only through the two electrodes on the same side, and because the electrode is only located on one side of the temple, it is only necessary to replace a single temple to make it Glasses get powerful features and quite an advantage.

However, due to the difference in the shape of each person's face, it is possible that the contact between the electrodes on the side of the eyes and near the temples and the skin may not necessarily be close to each other. Therefore, it can be further implemented as, as shown in Figure 9B, below the electrodes on the side of the eyes A protrusion 66 is provided to ensure the contact between the electrode and the skin, and during implementation, in addition to adopting protrusions of different heights according to different face shapes, the protrusions can also be implemented as having elasticity to adapt to different face shapes; or As shown in FIG. 9C, an extension part 68 protruding upward from the temples can also be extended to the forehead, for example, to touch the edge of the hairline, so as to extend the electrode that was originally located near the eyes into an electrode 62'. In this way, In addition to measuring the eye movement signal, the activity situation of the frontal lobe area of the cerebral cortex can also be obtained, or as shown in Figure 9D, it can also be extended to the back of the head through the extension part 69, so that the area that was originally located near the ear The electrode is extended to be an electrode 64' to obtain the activity of the occipital region of the cerebral cortex. Here, the extension part can be formed in other ways besides being directly formed on the temple. A port is provided on the temple to connect the extension part, or the extension part can also be implemented to be in contact with the electrode, for example, it can not only form an electrical connection but also achieve mechanical fixation with the electrode by means of magnetic attraction, and thus Instead, extend the electrode to other locations. Therefore, all possibilities are possible without limitation.

In addition, in particular, as shown in FIG. 11E , the brain activity of the occipital region can also be obtained by combining the modules to extend the temples to the position behind the head, or the temples can also be directly formed to have a backward extension. , and when there is hair at the contact position of the electrode, for example, there is hair on the back of the head, and there are sideburns on the side of the head, the contact ensuring structure can be used to obtain the signal through the hair, for example, using the above-mentioned The stretchable electrodes, and/or dispersed into multiple contact points, etc., therefore, are not limited, as long as a stable contact between the electrodes and the skin can be achieved.

On the other hand, in addition to obtaining EEG signals and/or electro-oculogram signals, the distance between the two electrodes can also be shortened to obtain electromyographic signals or skin electro-dermal signals, or it can also be implemented in such a way that one electrode is located on the inside and the other electrode From the outside, the user can measure the ECG signal by contacting the electrodes with the upper limbs. Alternatively, an optical sensor can also be installed to obtain blood physiological signals. Therefore, there are various possibilities, and they are not limited to individual implementations, and can also be combined and implemented on the same temple.

Here, similarly, the circuit system for performing electrophysiological signal acquisition can be implemented as being directly arranged in the temple (as shown in FIG. In the combination module 40 (as shown in Figure 11B) that is electrically connected (also can be implemented as ear-worn form), or in the combination module 40 (as shown in Figure 11E) that is implemented as combining with the temple end It can also be implemented in various forms as previously described, without limitation.

Furthermore, it can also be implemented that both mirror feet are replaced, and in this case, it is necessary to use wiring to achieve the electrical connection between the two mirror feet. For example, as shown in Figure 12A, it can be The circuit system 100 has been installed in the mirror base 702, and the two mirror bases 702 and 704 have been respectively provided with electrodes 72 and 74 on the surface. Therefore, when there is a need for measurement, the user only needs to connect the connecting wires 70 to the The electrical ports 42 on the two mirror feet are sufficient; or, as shown in Figures 12B-12C, the main circuit system is set in the combination module 40, and when there is a need for measurement, the combination module is connected to one mirror foot 702 40, and the mirror pin 704 on the other side is connected to the connecting wire 70, or the combination module 40 is connected to the two mirror pins respectively through the connecting wire, and the sampling circuit can be completed, which is also very convenient, and, because the connecting wire will be located at the head The rear, therefore, also does not affect the styling effect of the front.

Alternatively, as mentioned above, the conductive part in the glasses structure can also be used to complete the connection between the electrodes and the circuit system. For example, in the embodiment shown in FIG. 12D , electrodes 72 have been provided on the temples of one side of the glasses structure, while the circuit system is mainly provided in the earwear structure and connected to the other side through the port 42 and another electrode 50 is arranged on the surface of the coupling module implemented as an ear-wearing form, for example, an in-ear housing, so as to contact the skin of the ear when the in-ear housing is placed on the ear, With such a setting, as long as the electrode 72 is electrically connected to the port 42 through the conductive part in the glasses structure, when the user wants to perform a measurement, he only needs to plug in the ear-wearing structure and complete the setting of the ear-wearing structure. Yes, it is also quite convenient. Here, it should be noted that although for the convenience of use, the combined module is implemented in the form of ear-wearing, but it is not limited, and it can also be implemented in the form of Figure 12B, and the electrodes on it can be selected to contact V-shaped Dimples, the back of the pinna, the mastoid bone, or/or the area of the head near the ear are acceptable.

In addition, it can also be implemented as shown in FIG. 12E. In this embodiment, the combination module is also implemented in the form of an external connection, and has a circuit system disposed therein, while the two electrodes 72, 74 are already disposed on the glasses. Structurally, they are respectively connected to the ports through the conductive parts in the glasses structure. Therefore, when the user wants to measure, he only needs to connect the ear-wearing structure, or the combination module as shown in Figure 12B. It is a very advantageous implementation mode.

In addition, it should be noted that although Fig. 12A-12E shows the case where only one electrode is provided on one side of the temple, it can also be implemented as two electrodes on both sides of the temple or a single mirror without limitation. Set two electrodes, etc., without limitation. In addition, in addition to the traditional glasses as shown in the figure, the structure of the glasses can also be the glasses with no hinge structure as shown in FIG. 10B , which can be changed according to actual needs.

Next, according to another aspect of the present invention, while endowing the glasses with the ability to capture electrophysiological signals, a control mechanism is further provided. Please refer to FIG. 13A, which shows a schematic diagram according to a preferred embodiment of the present invention. As shown in the figure, at the junction of the frame unit and the mirror pins, the frame unit 806 and the mirror pins 802 are respectively provided with corresponding electrical contact points 82 , 84, so, through such a design, when the mirror feet 802 are unfolded, the electrical contact points 82, 84 on the mirror feet 802 and the mirror frame unit 806 will just be in contact with each other due to the mutual abutment of the mirror feet and the mirror frame unit, and When the temples are closed, the electrical contact is broken.

In the concept of the present invention, such electrical contacts are used to determine the state of the circuit system. Because when the glasses are not in use, the user generally closes the temples for carrying. Therefore, under such a premise, if a switch that can determine the state of the circuit system can be set at the position where the structure changes due to this action, The storage action of the glasses when not in use can be naturally linked to the state of the circuit system, for example, whether the circuit system is connected to the electrodes, or whether the circuit system can perform physiological signal acquisition, etc.

When the state of the sampling circuit system can be determined by opening and closing the glasses, it is advantageous that, first of all, the effect of power saving can be achieved. Since the glasses are a structure worn on the face, it is naturally best to reduce the The weight and volume are reduced to increase the user's willingness to use, and the battery almost accounts for the largest weight and volume of the wearable physiological detection device. Therefore, if such a mechanism can be used to ensure that when the glasses are not in use, the power will not It is definitely a very advantageous design; moreover, it can achieve the effect of reducing the amount of data. Since wearable physiological detection devices mostly perform long-term measurements, the amount of accumulated data is quite large. Therefore, Such an approach will effectively reduce the amount of data, and both human interpretation and cloud computing resource consumption can be reduced.

In actual implementation, there are several possible ways. For example, the corresponding electrical contact point can be a switch in the circuit system and/or electrode separately disposed on the frame unit and the temples, which is opened when the temples are closed and closed when the temples are unfolded. , therefore, the existence or non-existence of electrical connection between the circuit system and the electrodes can be determined by the opening and closing of the mirror legs. Setting, for example, one group, two groups, or multiple groups of contact points can be set to achieve one, two, or multiple electrical conduction loops, as shown in Figure 13B, which is the mirror frame unit 806 and mirror feet 802 with two relative The case of group electrical contacts.

In addition, it can also be implemented in the case where all electrodes, circuit elements, etc. are located in a single temple. At this time, the electrical contact point plays the role of conducting the circuit system in the temple. For example, as shown in FIG. 13C, the A single contact point 82 is set on the mirror frame unit 806 to contact the two contact points 841 and 842 on the mirror legs simultaneously when the mirror legs are unfolded. Entering a state where the physiological signal acquisition can be performed, that is, the electrical connection is used as an indication of whether the physiological signal acquisition can be performed. Therefore, the actual configuration of the electrical contacts can be varied according to different requirements without limitation.

In addition, the conception according to another aspect of the present invention is aimed at the glasses structure in which the conductive parts on the frame unit and the mirror feet are connected to each other, that is, the glasses structure itself can realize the signal transmission function.

This kind of glasses structure can have various possibilities, for example, it can be that the mirror feet and the frame unit are all made of metal material as shown in Figure 14A, and they are joined with each other by using a metal hinge structure, or as shown in Figure 14C The spectacles structure with no hinge structure shown can be implemented as being made of metal materials; in the spectacles structure made of plastic materials, conductive parts are arranged in the frame unit and the mirror feet, for example, built-in circuits The board carries the circuit and is connected to each other through a metal twist structure; in addition, it can also be made of a metal material covered with a plastic material or acetate fiber material, so there is no limitation.

Among them, among the glasses structures that meet this requirement, the most common ones are the so-called metal-frame glasses, that is, as shown in Figure 14A. Therefore, in the following descriptions, we will mainly use this type of glasses as the basis. It is described, but as is well known to those skilled in the art, it is not intended as a limitation, and the same embodiment can also be applied to other eyeglass structures with the same characteristics.

The structure of metal frame glasses also includes a frame unit and two temples. Generally speaking, in the common structure of metal frame glasses, the frame and temples are mostly made of metal. However, as we all know, the nose pad The material may vary, for example, rubber pads are used, or the same metal material is used. In addition, the temple ends of some metal glasses are covered with temple covers of different materials; in addition, the metal frame shown in Figure 14C The glasses structure is that the frame unit and the temples are integrated, for example, formed by a single piece of elastic metal.

Therefore, when the metal frame glasses structure is used, no matter where the electrodes are arranged on the metal glasses structure, as long as they can be electrically connected with the metal material, electrical signal transmission can be performed without additional wiring.

For example, one of the possible implementations is, please refer to FIG. 14A , a combination module 40 is provided on the mirror leg 902 on one side, and a combination electrode part 90 is set on the mirror leg 904 on the other side, and The combination module and the combination electrode part are respectively provided with electrodes 92 and 94 on the inner side of the contact head. Therefore, based on the characteristics of the metal frame glasses, the combination module and the combination electrode only need to be in contact with the end of the mirror pin on the inside. Set the electrical connection point at the position, and ensure that the installation action can achieve a stable contact between the electrical connection point and the mirror foot. In this way, when the combination module and the combination electrode parts are installed, the entire sampling circuit is completed, and the user As long as you wear glasses, the electrodes on both sides can obtain EEG signals by contacting the two sides of the head respectively, and the electrical signals from the combined electrode parts will be transmitted to the The binding module 40 .

In this way, the user only needs to purchase the combination module and the combination electrode parts, and then install the combination module and the combination electrode parts on his own glasses when it is necessary to measure, and then the physiological signal detection can be carried out, which is quite convenient .

Another possible implementation is, please refer to FIG. 14B , which shows the situation where the electrodes are set between the eyes, and the nose pads are used as the electrodes. Here, the nose pad electrodes 96, 98 can be in the original glasses structure. The metal nose pads directly connected to the metal mirror frame can also be electrically connected to the metal mirror frame by covering conductive parts, there is no limitation. Therefore, the electrodes on the nose pads and the electrodes 92 on the combination module can be used together to obtain electro-oculogram signals and EEG signals, which is also a very advantageous choice.

Alternatively, the glasses structure shown in FIG. 14C can also be used. At this time, by arranging the combination module 40 on one side of the temple and setting the combination electrode part 90 at the area between the eyes, the electrodes on the combination module can 92 contacts the skin of the head on one side, and the electrode (not shown, located inside the glasses) on the combined electrode assembly contacts the skin in the area between the eyes, for example, Yamane, to obtain electro-oculogram and EEG signals.

Another possible implementation is that, as shown in Figure 14D, an electrode 9041 has been formed in advance on the one-sided temple 904. For example, as mentioned above, the method of replacing the temple can be used. The combination module 40 is installed on one side of the temple, and the EEG signal can be obtained through the electrodes 92 and 9041 .

Yet another possible implementation is, as shown in FIG. 14E , under the condition that there is a stable contact between the temple 904 and the side of the head and/or the skin of the ear, the temple 904 is directly implemented as an electrode, for example, by The position where the mirror foot touches the V-shaped depression cooperates with the electrode 92 on the combination module 40 to obtain EEG signals.

Therefore, as long as it is confirmed that the conductive parts in the spectacle frame unit and the spectacle feet have been conducted with each other, the physiological signal acquisition function can be easily obtained through the above method, especially for those who originally wear metal frame spectacle structure, the simplest The most common situation is that you only need to install an external module to obtain the physiological signal acquisition function, which is quite conducive to improving public acceptance.

Here, it should be noted that although the electrodes depicted in Figures 14A-14E are all directed towards the head, when actually implemented, they can also be implemented as a position that contacts the V-shaped depression downwards as described above, and, Whether it is a combination module or a combination electrode part, it can be implemented to have the ear contact part as mentioned above to carry the electrodes, thereby ensuring the contact between the electrodes and the skin. In addition, as shown in Figure 14E, when directly using the glasses structure When the mirror legs are used as electrodes, the ear contact parts can also be arranged on the mirror legs to ensure the stability of the contact.

In addition, for the spectacle structure that can achieve the signal transmission function itself, the present invention further provides another possibility of setting electrodes, that is, setting electrodes in an external way, for example, using an external component connected to the temple , so that one of the electrodes used to obtain physiological signals is arranged on the outside of the glasses structure. For example, FIG. The feet are connected to an inner ear shell 920 through a connecting wire, so by setting the inner ear shell, the electrodes will come into contact with the inside of the ear, or, the external connection element 930 can also be implemented as shown in Figure 14G In this case, the electrodes 940 are disposed on the surface of the external component 930 electrically coupled with the temples, so as to contact positions such as the back of the ear and/or the mastoid bone.

In this case, several options are available for obtaining physiological signals. One of the options is to use two electrodes to collect physiological signals. At this time, because the structure of the glasses itself can transmit signals, another electrode can be arranged at any position on the glasses. For example, the external part 930 is connected to the Physiological signal acquisition can be performed on the mirror feet, the frame unit, or the mirror feet on the other side.

Another option is that, as mentioned above, the original glasses structure already has two electrodes to obtain electrophysiological signals, and the electrodes connected to this external component can therefore change the sampling position, sampling Combination paradigm, sampling signal type, etc. Among them, there are also two options to replace one of the original electrodes, or to carry out signal acquisition together with the original electrode, so as to compare the reference combination paradigm and bipolar combination paradigm, as well as single-channel Change between sampling loop and dual channel sampling loop.

Here, it should be noted that the number of electrodes is not limited to the aforementioned embodiments, and since the structure of the glasses itself can conduct signal transmission, the location of the electrodes can also be changed according to the measurement requirements, for example, The electrodes can be arranged according to the well-known 10-20 electroencephalogram electrode configuration method (International 10-20 System), or according to a larger number of electrode configuration methods, or arranged at other positions to be detected. There are various possibilities.

On the other hand, according to yet another idea of the present invention, a further improvement is made on the temples. As mentioned above, the purpose of the present invention is to provide the physiological signal acquisition function for the glasses structure without changing the front appearance of the glasses structure. Therefore, the temples will be the most suitable location for the improvement.

Please refer to FIG. 15, which shows a combination of glasses according to a preferred embodiment of the present invention, wherein a glasses structure has a frame unit and two temples, here, particularly, one of the temples is implemented as having a The replacement part 1100 and the corresponding combination part 1200 can form a complete shape of the temple when they are combined.

In the idea of the present invention, it is hoped that the structure of the glasses can be changed according to the needs through the design of the replaceable part, that is, the replaceable part can be replaced with a different replacement part to provide more possible physiological signals Fetch function.

In one of the embodiments, the replacement part is implemented as a light sensor module 130, and the light sensor module has included at least part of the circuit system and components required to capture the physiological signal. In this case, when When the glasses structure is worn on the user's head, the optical sensor 132 arranged on the surface will be located near the ear, for example, above the ear, in the V-shaped depression, or behind the ear, and obtain blood physiological signals through this position, for example, Pulse wave signal, blood oxygen concentration, etc., and the heart rate can be obtained by analyzing the pulse wave signal.

The advantage of this embodiment is that even if it is only a common glasses structure, as long as the replaceable part is provided at the temple, the physiological information provided by the optical sensor, such as heart rate, can be obtained simply through mechanical combination. Therefore, as long as you wear glasses, you can easily and naturally obtain physiological information in your daily life; and, furthermore, compared with the form worn on the hand, the movement of the head is relatively small, which will provide better Stable signal source.

In another embodiment, the replacement part is implemented as an electrode module, and the electrode module already includes at least part of the circuitry and components required for capturing electrophysiological signals. For example, in one case, the electrode module 140 can have two electrodes 141, 142 that simultaneously contact the skin of the head to obtain local myoelectric signals, skin electrical signals, brain electrical signals, etc.; or, another In one case, the electrode module 150 has an electrode 152 on one side that contacts the skin of the head, and another electrode (not shown) is used for contacting the upper limbs to obtain ECG signals. In this way, the glasses can obtain the electrophysiological signal acquisition function simply through the replacement action of mechanical combination.

On the other hand, the spectacle structure with the replaceable part can also be the spectacle structure already having the circuit system and the physiological sensing element as mentioned above.

For example, in one embodiment, the replacement part can be used to change the electrode type. For example, the replaceable part already has electrodes on it, so as to cooperate with other electrodes on the glasses for signal acquisition. Since the brain is divided into many areas, and different brain areas are in charge of different physiological activities of the human body, and the brain activity obtained through the electrodes is the brain activity of the cerebral cortex area below the electrode position, therefore, if you want to understand the different areas of the brain Cortical activity must be changed by changing the position of the electrodes, and this replaceable part provides such a possibility. For example, the replaceable part 162 can also be implemented to extend upwards, so that the electrodes can obtain brain activity in the temporal lobe area Alternatively, the replacement portion 164 may be implemented to extend farther back so that the electrodes can pick up brain activity in the occipital region of the cerebral cortex at the back of the head. Therefore, the diversity of physiological signal acquisition can be increased through simple replacement. Here, when hair may be hidden at the position where the electrodes are installed, for example, behind the head or above the ears, the connection between the electrodes and the electrodes can be ensured by adopting the above-mentioned contact ensuring structure, for example, needle-shaped electrodes, dispersive electrodes, etc. skin-to-skin contact.

Further, the replacement part can also be used to change or increase the physiological signal to be captured. For example, the replacement part 170 can provide a light sensor 172, so that the original glasses structure can increase the function of obtaining blood physiological signal; Alternatively, if the glasses originally only have electrodes on the other side of the temple and/or the frame unit, the replacement part 180 can be used to provide electrodes 182 on the side of the temple to increase the position for obtaining EEG signals; or , replace the replaceable part with the electrode with the replacement part without any physiological sensing element, and change the sampling position of the EEG signal, for example, the EEG signal obtained from both sides of the head is changed from the area between the eyes and one side of the head to obtain EEG signals. Therefore, various possibilities are possible.

Here, it should be noted that the replacement part described in the above-mentioned embodiment is only used as an example, not as a limitation, and it can have various changes according to the actual design and structure of the glasses structure combined with it, and is not limited to In the above situation, as long as the physiological signal acquisition function of the glasses structure can be changed by replacing the replacement part, it all falls within the applicable scope of the present invention.

In addition, the above-mentioned situations can also be implemented in combination, for example, the photosensor and the electrode can be installed in the replacement part at the same time, or the photosensor can be added while changing the electrode type, etc., are all feasible ways without limitation.

Therefore, through the replacement part, more detection possibilities can be given to the glasses structure, which is also a very advantageous choice.

In addition to using the method of replacing the replaceable part to obtain the physiological signal acquisition function of the glasses structure, an external combination method can also be used, as shown in Figures 16A-16B, a combination module 40 can be combined on a glasses structure, and The combination module itself has a complete physiological signal acquisition function. For example, the combination module shown in FIG. Oculoelectric signals, myoelectric signals, and/or skin galvanic signals, or, alternatively, one electrode on the combination module can also be set so that one contacts the skin of the head, while the other can be contacted by the upper limbs, so as to obtain electrocardiographic signals; In addition, FIG. 16B shows a schematic diagram of the light sensor 1114 provided by the combination module, and by setting the light sensor, the combination module can obtain blood physiological signals, and then obtain pulse wave signals, blood oxygen concentration, and the like. Of course, it is also possible to have electrodes and photosensors on one combined module, without limitation.

In a preferred embodiment, as shown in FIG. 16C , the combination module 40 is implemented with a curved portion, which can face the back of the head when combined on the temple, and has an ear-wearing structure, such as the inner shell of the ear The body 920 can be combined with the ear, wherein an electrode 1115 is arranged on the inner side of the curved part, and implemented in a dispersed form, so as to overcome the shading of the hair, here, further, each dispersed contact point can also be implemented as a The telescopic form is more helpful to achieve contact with the skin. Another electrode 1116 is set on the ear-wearing structure. In this way, the electrode set on the ear-wearing structure is regarded as a reference electrode, and the electrode on the combined module The electrodes are regarded as activity detection electrodes, which can obtain EEG signals in the occipital area of the cerebral cortex; or, alternatively, the binding module can also be implemented to contact the V-shaped depression, so that the cerebral cortex can be obtained. EEG signals in the temporal lobe.

Here, it is advantageous that the circuit system can be arranged in the combination module and/or the ear-wearing structure without limitation, and the combination module can be implemented as plugged in or sleeved on the temples, especially relatively Preferably, the above-mentioned adjustment mechanism is implemented on the ear contact part to align with the same position of different users, for example, the V-shaped depression, so as to make the use more convenient, so there is no limitation.

Here, when setting up the combined module, it is preferable to choose one that allows the relative position between the electrodes and/or the light sensor and the head to be continuously maintained stable, for example, the upper part of the ear can rest on the ear through the mirror feet In order to obtain stable strength, or use the shape of the combined module to achieve a stable contact position behind the ear.

In this way, regardless of the structure of the user's glasses, the physiological signal acquisition function can be obtained through the combination module, which is not only convenient to use, but also helps to increase the user's acceptance, which is quite advantageous. The way.

Next, the scope of application of the glasses structure according to the present invention will be described.

As mentioned above, the glasses structure according to the present invention can obtain various electrophysiological signals, such as electroencephalogram signals, electrooculogram signals, myoelectric signals, skin electrosignal An additional optical sensor can be installed to obtain blood physiological signals, such as pulse wave signals, blood oxygen concentration, etc., and the glasses structure is suitable for long-term wear on the face, so that the glasses structure according to the present invention has various applications possible.

For example, it can be applied to neurophysiological feedback programs. Common purposes of neurophysiological feedback include, but are not limited to, relaxation, and improvement of concentration, etc., and the physiological information mainly referred to by neurophysiological feedback is to obtain brain activity by measuring EEG signals, and through the glasses structure of the present invention To set the electrodes, not only the setting of the electrodes becomes quite convenient, but also the neurophysiological feedback procedures for improving physical and mental conditions can be carried out at any time and place.

In addition, there is also a kind of neurophysiological feedback whose purpose is to train the balance of the left and right brains, or to understand whether the left and right brains are synchronized, and this kind of situation is especially suitable for the EEG detection device in the form of glasses of the present invention, because the original glasses have The structure has mirror feet that are erected on the two ears respectively, which can contact the two sides of the head respectively, for example, the temporal lobe area of the cerebral cortex (electrodes contacting the temporal lobe area are set on the mirror feet on both sides), or the cerebral cortex occipital area. lobe area (set the back-curving structure of the temples in Figure 11E on both temples), or the frontal lobe area of the cerebral cortex (use the upper edge of the mirror frame to touch the upper eye socket), etc. Therefore, it is only necessary to configure the electrode position appropriately. The activities of the left and right hemispheres can be naturally obtained separately. For example, a common reference electrode can be set, for example, at the position where the end of the temple contacts the mastoid bone, or on the external ear-wearing structure, and different A single electrode on the mirror leg forms a sampling loop (dual-channel reference combination paradigm); or, a reference electrode can also be set on both mirror legs to form a sampling channel with the electrodes on the same or the other mirror leg , can also obtain the activities of different hemispheres (dual-channel reference combination paradigm); or, two electrodes can also be set on each temple, and let the two electrodes on one temple form a single sampling channels, the activities of different hemispheres can be obtained respectively (two-channel bipolar combination paradigm).

In addition to understanding the activity of the left and right hemispheres, when the electrodes are placed closer to the eyes, for example, the position where the frame of the mirror contacts the eye, or the position where the temples contact the side of the eye, etc. The number can also be used to understand the movement of the left and right eyes, so it has various uses.

And in a special embodiment, then be implemented as, the electrode on the nose pad on the right side and the electrode on the mirror leg of the right side form a sampling circuit, and the electrode on the nose pad on the left side and the electrode on the mirror leg of the left side form a sampling loop. circuit, this way is especially beneficial to obtain the separate actions of the left and right eyes, here, only need to pay attention to separate the circuits of the two circuits, for example, implement the metal parts in the mirror frame as two parts that are not connected on the left and right In this case, the distribution of the circuit can be directly set in the left and right part of the glasses structure respectively, or it can also be connected through an external module and temple Arranging circuits in combination is a possible implementation.

Furthermore, it can also be applied to general physiological feedback procedures. For example, a large part of the physiological feedback is aimed at relaxing the body and mind, and the electrodermal signal is the most common physiological signal used to represent the degree of relaxation in the physiological feedback procedures. In addition, EMG signals can also indicate the degree of muscle tension, which is also a physiological signal related to relaxation.

Moreover, through the information providing unit of the present invention, for example, lenses, light-emitting elements, display elements, display units, etc. arranged on the glasses structure, earphones, etc. Computers, etc. In the various physiological feedback programs mentioned above, users will be able to understand the changes in their own physiological states in real time, for example, through visual, auditory, and/or tactile means, and use them as a basis for self-awareness control.

In addition, when the optical sensor is installed, the user's blood physiological signals, such as pulse wave signals, blood oxygen concentration, etc., can be obtained. Among them, when continuous pulse wave signals can be obtained, heart rate changes can be obtained. In addition to knowing the heart rate changes during wearing, it can also be further used to obtain RSA information (Respiratory Sinus Arrhythmia, sinus arrhythmia), and through the RSA information, the user's breathing situation can be known. Accordingly, according to the present invention The glasses structure can be applied to breathing training, for example, it can cooperate with the information providing unit to provide user breathing guidance, and/or the physiological state that changes due to breathing training, etc. In addition, through the heart rate variability (HRV, Heart rate variability) can also understand the activity of the autonomic nervous system, which is also an important basis for judging whether the human body is in a state of relaxation or tension.

In addition, since increasing the amplitude of RSA can help trigger the relaxation response (Relaxation Response), relieve accumulated stress, and achieve the effect of increasing the ratio of parasympathetic nerve/sympathetic nerve activity, therefore, by observing the user's heart rate change pattern, and When the heart rate begins to accelerate, the guide informs the user that it is possible to inhale, and when the heart rate begins to slow down, the guide informs the user that it is possible to start exhaling, so as to achieve the effect of increasing the RSA amplitude, that is, to cause a gap between breathing and heart rate. The coherence (coherence) also helps to achieve relaxation. Furthermore, because the magnitude of the amplitude obtained by the peak and trough of RSA, that is, the difference between the maximum value and the minimum value of the heart rate in a breathing cycle, will be related to the activity of the autonomic nerve. Therefore, Also, this information can be provided to the user in real time as a basis for the user to adjust physiological activities.

And in a special embodiment, as shown in Figure 17, the circuit system is set in a wrist-worn structure, for example, in a watch, bracelet, that is, the user can have the function of picking up EEG signals at ordinary times The watch/bracelet is worn on the wrist. When it is necessary to measure the EEG signal, it is connected to the glasses structure to complete the electrical connection with the electrodes on the glasses structure. Or, the wrist-worn structure and glasses are usually worn. Connecting the two when there is a need for measurement is also a very convenient and integrated choice for daily life, and this situation is especially suitable for physiological feedback and breathing training.

Due to the portability provided by the wrist-worn device and the convenience of setting the information providing unit on it, coupled with the design that the EEG signal can be obtained only by matching the structure of the glasses, the user can almost unlimited time and place. Physiological feedback/breathing training, at this time, if you can further set electrodes on the wrist-worn structure to obtain ECG signals together with the electrodes on the glasses structure, or set a light sensor on the glasses structure or wrist-worn structure to obtain heart rate , can understand the breathing situation from this, and then execute the breathing training program, and if there are ECG electrodes and light sensors at the same time, the pulse transit time (PTT) can be obtained, and then calculated using the relationship between PTT and blood pressure Reference blood pressure value, or further use PPT as physiological feedback information. Therefore, a variety of physiological information can be obtained only by wearing the wrist-worn structure and the glasses structure, and the operation is convenient, which is quite an advantageous implementation mode.

Moreover, since the setting position of the wrist-worn structure is exactly the position where the information-providing interface is generally set, for example, a watch, a bracelet, therefore, during physiological feedback or breathing training, it is natural to provide physiological feedback through the wrist-worn structure. Information, and/or breathing guidance, etc., or as an input interface for the user, is quite convenient. In addition, if the user chooses to close the eyes for physiological feedback or breathing training, it can also be connected to a sound-generating element, For example, it is connected to the wrist-worn structure, or extends from the glasses structure, or is set on the glasses structure to generate audio, for example, several audio files that have been stored, or generate audio in real time, for example, with a specific Frequency audio, and the audio can be sound and/or voice, and then give feedback and/or guidance to the user through hearing; or give user feedback and/or guidance through the vibration of the wrist-worn structure and/or glasses structure / or bootstrap, both are quite advantageous ways.

Here, the sound-generating element can be implemented to be arranged on an ear-mounted structure, for example, implemented as an earphone to be worn on the ear to make it more convenient to use, and furthermore, it can also be arranged on the ear-mounted structure Electrodes, for example, are arranged on the surface of the inner shell of the ear to obtain EEG signals, for example, as mentioned above, together with the electrodes on the glasses structure to obtain EEG signals, for example, as reference electrodes, or two Electrodes can be used to obtain EEG signals alone. Or, the ear-worn structure can also be provided with electrodes that can be contacted by the upper limbs. In this way, ECG signals can be obtained together with the electrodes on the glasses structure, or Use the electrodes on the ear-worn structure and the electrodes on the wrist-worn structure to obtain ECG signals; moreover, an optical sensor can also be set on the ear-worn structure to obtain the heart rate, and as mentioned above, the physiological Information, such as HRV, RSA, breathing behavior, etc., can also be applied to physiological feedback and/or breathing training. In addition, when using two wearable structures to obtain ECG signals, for example, electrodes on the wrist-worn structure cooperate with glasses The ECG signal can also be used to perform physiological feedback and/or breathing training when the electrodes on the structure/ear wear structure.

Furthermore, in addition to the above-mentioned functions, the wrist-worn structure can also provide other physiological signal detection options. For example, electrodes can be placed on the surface that is in contact with the wrist and also on another surface that can be touched by the upper limb. Electrodes, so as to obtain ECG signals by contacting the electrodes with both hands; or, two electrodes can be arranged on the surface of the wrist contact, so as to obtain skin electrical signals and/or electromyographic signals; or, extend a finger-wearing structure, and the The finger-worn structure can be implemented with two electrodes on the surface in contact with the finger to obtain skin electrical signals and/or electromyographic signals, or only have one electrode and cooperate with another electrode that can be contacted by another upper limb For example, it can be installed on the wrist-worn structure, glasses structure, or finger-worn structure to obtain ECG signals, wherein the finger-worn structure can also be used to install light sensors to obtain blood physiological information such as heart rate and blood oxygen concentration. It is quite an advantageous way. In addition, the acquisition of electrodermal signals can also be achieved through electrodes on the wrist-worn structure and electrodes on another wearable structure, such as a finger-worn structure, a glasses structure, or an ear-worn structure.

In addition to being used in physiological feedback and breathing guidance, it can also be used to detect the mental state of the human body.

A person's mental state can be known through many physiological signals, such as EEG signals, oculoelectric signals, and the activity state of the autonomic nervous system. Among them, different brain wave frequencies represent different mental states of the human body. For example, when the human body When awake and focused, a dominant beta wave (approximately 12-28Hz) can be measured, on the other hand, when the body is in a relaxed state, a dominant alpha wave (approximately 8-12Hz) can be measured , and when you are about to enter a sleep state, you can observe lower frequency brain waves.

Furthermore, in the autonomic nervous system, when the activity of sympathetic nerves increases, the human body tends to be in a tense state, while when the activity of parasympathetic nerves increases, it tends to make the human body enter a relaxed state. Physiological phenomena will also have corresponding changes. For example, when the activity of parasympathetic nerves increases, the heart rate will decrease accordingly. Therefore, by observing the physiological signals that reflect changes in the autonomic nervous system, it is also possible to understand a person's mental state.

In addition, a large number of experiments have also confirmed that blinking patterns are related to people's fatigue, lack of attention, and stress, and these also reflect people's mental state. Knowing the blink pattern, for example, whether the number of blinks per unit time has changed, and whether the blinking speed has slowed down, etc., is also helpful to understand the person's mental state, for example, whether there is drowsiness, and these can be obtained by obtaining eye signals. Learned.

As mentioned above, these signals can be obtained through the glasses structure of the present invention, and since it is hoped to detect people's waking state, drowsiness, or fatigue during daily life, study, and work, the glasses structure It has the advantages of being unobtrusive and highly acceptable to users, and will be the most suitable choice.

Furthermore, if multiple physiological information can be referred to at the same time, the accuracy of the detection results can be effectively improved. For example, while obtaining the EEG signal, the oculoelectric signal is also referred to to know the user's eyes. Activity status, or simultaneously analyze the state of brain wave and autonomic nerve activity, so as to increase the accuracy of judgment through multiple indicators.

Therefore, in a preferred embodiment, the present invention is implemented to judge the mental state of a person by simultaneously detecting EEG signals and eye movement signals. The selection of such a combination is based on knowing that the user is in a state through the frequency of brain waves. In the case of mental concentration or relaxation, if the eye movement signal can be used to confirm the user's eye activity state, it will help to judge that the user is not in a resting state. In addition, the eye signal can also provide the user with The information of the blink pattern, for example, as mentioned above, whether the number of blinks and/or the blink speed changes, so that the user's mental state can be judged more accurately.

As mentioned above, electrodes can be placed on the frame unit, such as the bridge of the nose, the root of the mountain, the area between the eyes, and around the eye sockets, etc., and then cooperate with the electrodes on the temples to simultaneously obtain EEG signals and electro-ocular signals. , and there is a certain degree of difference in the signal strength and signal characteristics of the two signals, therefore, the two signals can be separated by means of signal processing. Using two physiological signals to judge the mental state not only greatly reduces the complexity of setting physiological sensing components, but also maximizes the use efficiency, which is quite an advantageous way. Moreover, through this design, users only need to Wearing glasses can achieve the purpose of monitoring one's own mental state, which is quite convenient.

In another preferred embodiment, the present invention is implemented by simultaneously using electro-oculogram signals and heart rate information as the basis for judging the mental state. The reason why these two kinds of physiological information are used is that, in addition to analyzing the eye blinking pattern, heart rate information can also be used to obtain a lot of physiological information that can represent the mental state. For example, as mentioned above, Analyzing the heart rate information can lead to autonomic nerve activity information and breathing conditions, etc. Among them, the autonomic nervous activity can determine whether the mental state is tense or relaxed. In addition, when the mental state is relaxed, fatigued, or lethargic, the respiratory rate will also become lower. Therefore, this can also be used as the basis for judgment. In addition, the heart rate is under the control of the autonomic nervous system, and the heart rate will also drop during relaxation, fatigue, and lethargy. Therefore, by combining brain wave frequency and heart rate information, it can also help to judge the mental state of the user more accurately.

On the other hand, since the detection of the mental state is usually applied during work in general daily life, for example, during driving, the reminder mechanism is also very important. Advantageously, based on the structural characteristics of the glasses structure, when it is judged that the user's mental state is not good, for example, when a default value is met, a reminder message can be sent naturally through the information providing interface provided on the glasses structure, In order to improve the mental state of the user, for example, as mentioned above, by arranging light-emitting elements near the glasses, the effect of visual reminders can be achieved by arranging display elements, display units, etc., for example, emitting flashes, generating colors Changes, reminder messages, etc.; or, sounding elements (air conduction or bone conduction form) can also be set near the position of the temples close to the ears, or implemented as earphones (air conduction or bone conduction forms) extending from the temples to Remind by sound or voice; or, a vibration module can also be provided at the position where the glasses structure is in contact with the skin to generate vibration. In addition, it can also be implemented by setting the vibration module in the earphone, without limitation.

Of course, it can also be implemented to provide the judged mental state to the user in real time through the information providing interface. For example, the mental state can be digitized and displayed by numbers, or the color change and vibration size can be used There is no limit to expressing the current mental state through the volume, volume of voice, etc.

In addition, in addition to performing calculation/analysis on the obtained physiological signal through the processor module installed in the wearable structure to obtain a reminder message, it can also be implemented as transmitting the obtained physiological signal to the external device, and the external device The device analyzes the mental state according to the received physiological signals. At this time, the information about the mental state and the reminder message when it is necessary to remind the user can be directly provided to the user through the information providing interface of the external device. Or, or send it back to the wearable device, and provide it through the information providing unit on it. In another preferred embodiment, it is implemented that the device worn on the body transmits the generated mental state information and/or reminder message to the external device, and the information of the external device provides an interface to transmit the relevant mental state information and /or a reminder message is provided to the user. Here, it should be noted that the external device can also provide information and/or messages to the user by generating tactile, auditory, or visual signals, without limitation.

In addition, since the detection of the awake state is mostly during daily life, for example, driving for a long time, if the starting time point of the mark detection can be matched, for example, when entering the driving period, the detection of the mental state can be activated, which will be more effective. Accurately provide judgment results.

Furthermore, it can also be used to stimulate the human body to achieve effects such as changing the physiological state, brain state, and state of consciousness. For example, the more common function is to achieve relaxation and improve concentration, for example, to treat ADHD (Attentiondeficit hyperactivity disorder, attention deficit hyperactivity disorder), improve memory, change mental state, for example, treat PTSD (Post traumatic Stress Disorder, post traumatic stress syndrome), improve mental ability and performance (Mental Capability and Performance), change the brain State, for example, treatment of dementia (Dementia), change of cognitive state (cognitive state), change/induce sleep state and other effects.

For this application, the advantage of the glasses structure is that its original structure surrounds the head and covers the eyes, so that no matter it is visual, auditory, and/or tactile stimulation, it can be implemented, such as , display elements can be set on one side, or both sides of the frame or mirror feet close to the eyes, such as display elements, light-emitting elements, etc., to generate flashes, color changes, etc., for visual stimulation; or on the mirror feet close to the ears A sounding element (air conduction or bone conduction) is set near the position, or an earphone (air conduction or bone conduction) is connected to generate auditory stimulation; or an oscillator can be set on the frame and mirror feet, to generate vibration stimulation; or, further, electrical stimulation can be generated by setting electrodes. Similarly, when it is implemented as an ear-wearing structure, it can also generate these stimuli, for example, a display element can be extended from the ear-wearing structure, a sound-emitting element can be set in the ear-wearing structure, and/or a vibration module can be set in the ear-wearing structure, etc. , and conduct electrical stimulation through electrodes placed on the ear-wearing structure.

First of all, the glasses structure and the ear-wearing structure based on the present invention are originally provided with electrodes, so they are advantageously used for electrical stimulation.

For example, common electrical stimulation includes, for example, tCS (transcranial Current Stimulation, transcranial electrical stimulation), TENS (Transcutaneous electrical nerve stimulation, transcutaneous electrical nerve stimulation), MET (Microcurrent Electrical Therapy, microcurrent electrical therapy), And other known electrical stimulation, among them, the common form of tCS includes tDCS (transcranial Direct Current Stimulation, transcranial direct current stimulation), tACS (transcranial Alternating Current Stimulation, transcranial alternating current stimulation), and tRNS (transcranial Random Noise Stimulation, Transcranial random noise stimulation), and in particular, because transcranial electrical stimulation (applied current range is usually lower than 2 mA) is applied to the local physiological tissue above the cerebral cortex, thereby affecting the activity of the corresponding cerebral cortex, and therefore The applied current is very weak, therefore, during the period of electrical stimulation, the subject usually does not have obvious sensations, wherein different cerebral cortex regions (as shown in Figure 5A) are in charge of different functions of the human body correspondingly, for example , vision is mainly controlled by the occipital lobe, hearing is mainly controlled by the temporal lobe, somatosensory is mainly controlled by the parietal lobe, and advanced cognitive functions, such as language and self-awareness, are mainly controlled by the frontal lobe. Installed on the skull corresponding to different cerebral cortex regions, in addition to obtaining the activity of the corresponding cortical regions, it can also affect the cerebral cortex of the region by means of electrical stimulation.

There is another type of electrical stimulation, Electrode stimulation of tongue. According to research, electrical stimulation of the tongue activates two major cranial nerves: the lingual nerve (part of the trigeminal nerve) and the chorda tympani (part of the facial nerve), while stimulation of the cranial nerve activates Generates the flow of neural impulses to the somatosensory areas of the parietal cortex and to the brainstem, which is the control center for many vital functions, including sensory perception and movement, and then, starting from the brainstem, These nerve impulses travel through the brain and activate, or reactivate, neurons and structures involved in brain function -- the cerebral cortex, spinal cord, and, potentially, the entire central nervous system.

It is known that, in addition to achieving the various effects mentioned above, the application of electrical stimulation to the human body is also known to help improve certain symptoms, such as local pain such as shoulder and neck pain, migraine, depression, epilepsy, stroke, etc. , where the locations used for stimulation, such as the trigeminal nerve, vagus nerve, sympathetic nerve, cerebral cortex, etc., are all located near the head and ears, just adjacent to the structure of the glasses and the position of the ear-wearing structure, such as the earlobe, auricle, The ear canal, behind the ear, near the temple, forehead, top of the head, back of the brain, etc., for example, the many branches of the trigeminal nerve, such as the auriculotemporal nerve located near and above the ear, and the supraorbital nerve ), the supratrochlear artery nerve, and the ophthalmic nerve are located near the eye socket and forehead, and these are just the positions where the glasses structure/earwear structure will contact when it is placed on the head/ear, so , it is quite suitable to use the glasses structure and the ear-wearing structure to implement; moreover, it can also achieve the effect of improving the physiological state through electrical stimulation of acupuncture points.

For example, it can be implemented in the form of glasses, directly through the two electrodes arranged in the structure of the glasses, for example, the electrodes that contact the sides of the head, or the electrodes that contact the area between the eyes and the side of the head, can directly control the brain. In addition, when there is an ear-wearing structure at the same time, the electrodes on the ear-wearing structure can be used to electrically stimulate the brain together with the electrodes on the glasses. And since the electrical stimulation can be performed as long as the wearable structure is directly worn and the electrodes are contacted, no matter what form is used, the implementation of electrical stimulation can be made easier and more convenient.

In addition to directly using the electrodes on the wearable structure for electrical stimulation, other implementations are also possible. For example, the electrodes can be extended through the wearable structure as a medium for electrical stimulation. For example, only one Electrodes, and perform electrical stimulation together with one of the electrodes on the wearable structure, or extend two electrodes, and perform electrical stimulation through two extended electrodes, are all feasible ways, and when using the form of extended electrodes, Advantageously, the optional contact position becomes more extensive, not limited to the setting position of the wearing structure. For example, as shown in Figures 18A-18B, electrodes can be extended from the temples of the glasses to contact the back of the neck, Behind the ear, forehead, etc., electrodes can also be extended from the ear-mounted structure to contact the forehead, temples, behind the neck, behind the ear, etc. Two electrodes, but it can also be implemented that only one electrode extends, without limitation.

When the electrodes are extended, the electrodes can be placed on the skin using an attachment element, such as a patch as shown in the figure, or the attachment element can also be another wearable structure, such as a structure extending from glasses. There are ear-worn structures, neck-worn structures, arm-worn structures, wrist-worn structures, and finger-worn structures.

Alternatively, another wearing structure can also be extended from the ear-wearing structure, for example, another ear-wearing structure, a head-wearing structure, a neck-wearing structure, an arm-wearing structure, a wrist-wearing structure, a finger-wearing structure, etc., are all feasible ways, Among them, the head-wearing structure allows electrodes to be set in the frontal lobe area, parietal lobe area (as shown in Figure 19A-19B ) and occipital lobe area corresponding to the cerebral cortex according to the different setting positions, and the neck-wearing structure allows The electrodes are placed near the neck and shoulders, so they can be changed according to actual needs without limitation.

Furthermore, in particular, the attachment element can be implemented as an intraoral structure when performing tongue electrical stimulation, so that the user can place multiple electrodes on the tongue and, when performing tongue electrical stimulation, place electrodes on the The electrode configuration on the intraoral structure is preferably implemented in a matrix form, for example, a 9x9 or 12x12 electrode configuration, and when providing electrical stimulation, it can be implemented to have different electrical stimulation methods according to programming The change, for example, the electrical stimulation pattern (pattern) with time or space change generated through the electrode configuration, therefore, can be changed according to actual use requirements without limitation.

In addition, alternatively, when it is implemented as two extension electrodes, it may be implemented that two extension elements are used to carry them respectively, or it may be implemented that one extension element simultaneously carries two electrodes, without limitation.

Here, it should be noted that the electrodes used, whether they are electrodes placed on the wearable structure or extended electrodes, can be implemented as dry electrodes or wet electrodes, for example, electrodes using conductive paste , without limitation, among them, it is particularly advantageous that the use of self-adhesive wet electrodes, such as patch electrodes, can further improve the contact stability between the electrodes and the skin outside of the wearable structure, and there are many options for the implementation form, such as , can use wet electrodes in an extended form, or replace the electrodes of the original wearable structure with wet electrodes, all of which are feasible ways.

And when adopting the form of the dry type electrode, it is particularly advantageous that the contact ensuring structure as mentioned above can be adopted, for example, implemented as dispersed electrical contact points, and/or implemented as a stretchable structure, etc., especially Unfortunately, the contact point near the head is likely to be blocked by hair, and by adopting a contact securing structure, the execution of electrical stimulation will be ensured. Therefore, an appropriate electrode type can be selected according to the purpose of use without limitation.

In practice, an electrical signal is mainly generated by a signal generating unit and transmitted to the electrode connected to it, so that the electrode can apply electrical stimulation to the user. Therefore, by changing the electrical signal, the electrode applied to the user The electrical stimulation of the patient can be changed. Here, it should be noted that the generated electrical stimulation is in a non-invasive form, and the content of the applied electrical stimulation can be changed according to the purpose of the electrical stimulation. Waveform current and voltage changes, or, in the case of using pulse waves, even if the frequency is the same, the duration of stimulation can be changed through pulse width modulation (PulseWidth Modulation); or, in the case of using direct current for stimulation Under the present circumstances, direct current can be used as a bias voltage (offset), and a selected waveform is loaded on it, which is also a feasible way, so there is no limitation.

In addition, it is further advantageous that since the wearable structure of the present application is originally designed to obtain EEG signals and/or other physiological signals, the detection function of physiological signals and electrical stimulation can also be combined on the same device, Through such a combination, it is equivalent to directly providing a means to confirm the effect of electrical stimulation, which is undoubtedly a more advantageous choice.

For example, one of the physiological states that can be changed by electrical stimulation is the state of brain activity, and its changes can be known through EEG signals, for example, as mentioned above, the ratio of alpha waves to beta waves can be observed , and then understand the user's current relaxation and tension. In addition, through the multi-channel setting, the activity and energy difference between the left and right brains can be known. Furthermore, the potential difference between the left and right brains can also be observed. In addition, the cortical slow potential (SCP) can be used to understand the brain activity of concentration, and after understanding the state of brain activity, you can adjust various parameters of electrical stimulation, such as current, voltage, intensity, frequency, duty cycle , duration, etc., to affect the brain to achieve the goal, and after the electrical stimulation, the effect of electrical stimulation can be known by understanding the changes in brain activity, and adjustments can be made as a basis.

Alternatively, electrodermal activity (EDA, electrodermal activity) is also an indicator for observing physiological state changes. Electrodermal activity at the site of electrical stimulation can be obtained through electrodes placed on the head, or electrodes extending to other parts of the body, such as the neck, shoulders, wrists, and fingers, regardless of whether it is before the start of electrical stimulation, During and/or after the electrical stimulation, changes in electrical skin activity can be observed as a reference for deciding and/or adjusting the electrical stimulation mode.

Alternatively, changes in physiological state due to electrical stimulation can also be observed by detecting changes in heart rate. Heart rate variability (HRV, Heart Rate Variability) can be obtained by calculating the heart rate, and heart rate variability is the best way known to understand the autonomic nervous system. Therefore, whether the purpose of electrical stimulation is to relax, improve concentration, improve Mental state, improving sleep state, changing the state of the brain, or treating certain symptoms, by understanding the changes in the autonomic nerves, can effectively control the relevant physiological changes, and then use it as a basis for adjusting electrical stimulation. Here, the heart rate can be obtained by disposing an optical sensor or an electrocardiographic electrode, without limitation.

On the other hand, when the detection of brain waves detects that the user is drowsy, the effect of reminding and preventing falling asleep can also be achieved through the execution of electrical stimulation. For example, the user can choose to wear glasses, earphones, etc. when driving or reading. Neck wear structure, etc., and whether drowsiness occurs by monitoring brain waves, electrical skin activity, and/or heart rate, as the basis for generating electrical stimulation.

Here, it should be noted that when the detected physiological signal is an electrophysiological signal, the electrodes for obtaining the electrophysiological signal and the electrodes for performing electrical stimulation can be further implemented to be shared with each other, for example, one of Electrode sharing, or sharing of both electrodes, simplifies the overall configuration.

There are different implementation options for the implementation of generating and adjusting the electrical stimulation according to the physiological state. For example, it can be implemented such that the generation of electrical stimulation, the mode of electrical stimulation, and the parameters of electrical stimulation are automatically controlled by the signal generating unit, and it can also be implemented so that the user can operate by himself, for example, it can be displayed through the screen of a mobile phone or worn on the wrist. components, glasses lenses, or earphones, etc., and notify the user of the measured physiological state information, and then the user can decide whether to perform electrical stimulation, which electrical stimulation mode to choose, or Whether to adjust the parameters of the electrical stimulation, etc., of course, can also be implemented as an automatic or manual operation mode can be selected according to needs, and there is no limit.

For example, a set of electrical stimulation modes can be provided for the user to choose freely, or it can be further implemented as selecting a relevant electrical stimulation mode from the set according to the measured physiological state information before using it Alternatively, it can also be implemented so that the user can adjust the electrical stimulation parameter settings as described above, which are all possible implementations and are not limited.

Therefore, performing electrical stimulation through a wearable structure does provide a way to make the implementation of electrical stimulation easier. If coupled with the ability to obtain the user's physiological signals in real time, it will help improve the adjustment and selection of electrical stimulation modes. , and the effect that electrical stimulation can achieve, so it is indeed a very advantageous way.

On the other hand, on the premise that the glasses structure and/or the ear-wearing structure of the present invention can obtain EEG signals, in particular, it can also be applied to perform Physiological Resonance Stimulation.

First, a brain activity detection unit obtains EEG signals at a specific time through at least two EEG electrodes, and then performs frequency domain analysis processing on the obtained EEG signals through a processing unit, for example, through Fourier transform , or use a digital filter to obtain the energy distribution of the EEG signal, and then, in different brain wave frequency bands, for example, the delta frequency band (0.1-3 Hz), theta frequency band (4-7 Hz), slow alpha Band (8-9 Hz), Mid Alpha Band (9-12 Hz), Fast Alpha Band (12-14 Hz), Slow Beta Band (12.5-16 Hz), Mid Beta Band (16.5-20 Hz), Fast In the β frequency band (20.5-28 Hz), or other frequency bands, one or several energy peaks (peak energy) can be observed during this period, for example, an energy peak of 8 Hz appears in the α frequency band, or 8 energy peaks appear simultaneously. Hz and 10 Hz energy peaks, and after selecting a frequency range, for example, selecting the α frequency band, or a frequency range defined by itself, a stimulation signal generating unit can use the frequency of the energy peak in the frequency band as the Generate a physiological stimulation signal and apply it to the user.

Here, it should be noted that the specific time can be implemented in real time, for example, the frequency domain analysis process is performed once every second or less, or a longer period of time, for example, 5 minutes or longer Time, and then perform frequency domain analysis and processing for a long period of time, and then take the average value, or directly perform frequency domain analysis and processing for the entire period of time, are all possible methods, which can be changed according to actual needs, without certain restrictions.

As for the determination of the frequency of the stimulation signal, a better way after research is to select a frequency that has a frequency proportional relationship with the energy peak. For example, if the frequency of the stimulation signal is n and the frequency of the energy peak is m, then n and The proportional relationship where m is an integer is feasible. For example, n:m can be 1:2, 1:3, 2:3, 3:2, 3:1, etc., without limitation. Having a proportional relationship can be beneficial to achieve entrainment, and then achieve resonance phenomenon.

Here, it should be noted that as long as the peak energy frequency and frequency proportional relationship are determined according to the above method, a slight deviation can be tolerated in actual implementation, and all belong to the scope of the present invention without limitation. Stimulation signals with different ratios can be mixed, for example, two stimulation signals with a ratio of 1:2 and 1:3 can be mixed to facilitate synchronization/resonance through multiple harmonic components, and, The mixed signal ratio, strength and type can also be implemented to change over time. Moreover, when implemented to provide auditory stimulation, music can be further mixed, for example, sounds from nature, to increase user acceptance. Therefore, all possibilities are possible without limitation.

When the resonance is reached, one of the possibilities is that the effect of increasing the target peak energy can be achieved. For example, the selected 8 Hz energy peak will have an increase in amplitude, and the other possibility is that the selected The frequency of the energy peak in the frequency band is affected. For example, when the resonance is reached, the frequency of the externally applied stimulus can be changed, for example, from 8 Hz to 8.1 Hz, so that the traction force between the two generated by the resonance can make this The frequency of the energy peak is thus changed, and in this way, the traction effect of changing the original natural frequency can be achieved by gradually increasing or decreasing the stimulation frequency.

Further, by increasing the peak energy of the target, or by changing the frequency of the stimulation signal provided to achieve traction and affect the frequency of the energy peak, it is possible to change the physiological or brain state, and/or Or the effect of the state of consciousness, for example, can induce various physiological states of the human body such as sleep state, degree of wakefulness, degree of relaxation, meditation depth, etc., and can also be used for some diseases related to brain activity, such as epilepsy, migraine, etc. There is a positive effect.

As for the type of stimulus signal, there are various possibilities. For example, visual stimulus signal, auditory stimulus signal, or electrical stimulus signal are all feasible ways. For example, the visual stimulus signal can be a video with a proportional flicker rate. The signal, for example, can be implemented in the form of flashing lights by setting LEDs, LCDs, or other display elements. The auditory stimulation signal can be an audio signal with a proportional sound change frequency. For example, sound emitting elements (air conduction or bone conduction), and in a special embodiment, the generation of auditory stimulation signals can be achieved by two sound generation sources, that is, using the so-called binaural beats (Binaural beats) method, by providing Two auditory signals with a frequency difference, and make the frequency difference proportional to the frequency of the target peak, and when the two auditory signals are fed into the brain at the same time, the brain will eventually perceive the frequency difference The effect of a third auditory signal, and such two sources of sound generation, there are various implementations, for example, sound emitting elements can be set on the temples on both sides of the glasses structure, this method is especially suitable for bone conduction In this way, the structural shape of the glasses will not change much; alternatively, the sounding components can also be arranged on the ear-wearing structure extended from the glasses structure, for example, two sides can be extended from the single temple. Two ear-mounted structures, or one ear-mounted structure is extended from the two temples respectively, so as to be arranged on the two ears; or, it is also quite suitable for the situation where two ear-mounted structures are used separately, only need to add sound-generating components respectively That is, all of them can be implemented.

There are also different implementation forms of electrical stimulation. As mentioned above, the type of electrical stimulation can be changed by selecting different current and voltage application waveforms. In addition, electrical stimulation can also choose the stimulation site. Cranial Electrical Stimulation, Transcutaneous Electrical Nerve Stimulation, or through Tongue Electrical Stimulation, etc., so there are various possibilities.

Furthermore, in addition to applying a single stimulus, two or more stimuli can also be applied at the same time, for example, adding visual stimulation and auditory stimulation at the same time, or applying electrical stimulation and auditory stimulation at the same time, or applying stimulation to different cerebral cortex regions. Performing electrical stimulation at the same time is an optional execution method. In addition, the second stimulation source can also be implemented by an external device, such as a light source, a sound source, a mobile phone, etc., there is no limit, and in this case, many The frequencies of the two stimuli can be the same or different, there is no limit, as long as there is a frequency proportional relationship with the energy peak.

Then, after stimulating by means of resonance, through the detection of EEG signals, the effect of the stimulation can also be known by observing the brain waves during and/or after the stimulation, for example, whether the energy of the target peak has increased , and/or the magnitude of its increase, etc. Therefore, when the effect is not achieved, the execution method of the stimulus can be changed in real time, for example, when the magnitude of the energy increase is not as expected, the intensity of the stimulus can be enhanced, or the The timing of stimulation, or changing the waveform of the stimulation signal, etc., all help to increase the effect of stimulation.

Such a resonance stimulation method can accurately perform resonance stimulation on the existing brain wave frequency of the human body to achieve an enhanced effect, and can be adjusted in real time. It is a very efficient physiological stimulation method.

Here, in the same way, no matter the type of resonant physiological stimulation applied, or the mode of execution, parameter setting, etc., it can also be implemented to allow users to choose by themselves, for example, through the structure of glasses and ear-worn structures. Input operation interface, such as button, touch interface, light sensor, voice control, etc., or an external device that communicates with the structure of the glasses, such as a mobile phone, or a wrist-worn device. In addition, due to the resonance Physiological state changes caused by physiological stimuli can also be provided to the user through an information providing unit arranged on the structure of the glasses, or an external device that communicates with the structure of the glasses, for example, through visual, auditory, tactile, etc. It helps users to better understand their current physiological state, and also helps to achieve brain wave resonance.

In a special embodiment, as shown in Figures 19A-19B, it is implemented in the form of a headband placed on the top of the head and in-ear shells or earmuffs placed on both ears, such an arrangement is very suitable for obtaining cerebral cortex EEG signals in the parietal lobe area, where, as shown in the figure, when the ear-wearing structure is implemented in the form of an ear shell, the combination with the head-wearing structure is mainly implemented through connecting wires, and when the ear-wearing structure When the structure is implemented in the form of earmuffs, the combination with the headwear structure will mainly be implemented in the form of integrating the two, but it is not absolute, and other implementation modes are also feasible.

In practice, as shown in the figure, the two electrodes 191, 192 can be arranged on the headwear corresponding to the parietal lobe of the cerebral cortex to obtain EEG signals, or one more electrode can be arranged on the earwear structure. The electrode is used as a reference electrode to obtain dual-channel EEG signals using the reference combination paradigm with the two electrodes on the top of the head, or it can also be implemented as one electrode set on the headband and one electrode set on the ear-worn structure. Obtain the EEG signal of the parietal lobe area of the cerebral cortex; in addition, alternatively, the electrodes can also be placed close to the temporal lobe area of the cerebral cortex, for example, the position of the headband close to the ear, or on the ear-wearing structure, which is especially suitable for the ear The structure in the form of a mask can obtain the EEG signals of the temporal lobe area of the cerebral cortex, so it can be changed according to actual needs without limitation. In addition to obtaining EEG signals, the electrodes can also be used for electrical stimulation, such as transcranial electrical stimulation, resonance physiological stimulation, etc., or, electrical stimulation electrodes can also be set using attachment components, for example, extending from the head-mounted structure or Earwear structure. Here, further, in order to overcome the electrode contact problem that may be caused by the hair on the top of the head, the electrodes arranged on the headband are preferably implemented with the contact ensuring structure as mentioned above, on the one hand, the electrodes can pass through Hair, on the other hand also increases the contact area.

And because it just fits the form of a common headphone, it is also quite suitable for setting sound-generating elements (air conduction or bone conduction) in the ear-wearing structure, so that the user's audio frequency can be naturally provided. , for example, used to play music stored inside, such as mp3 sound files, or play music from an external device, or it can also be used to provide relevant physiological information, operation information, etc., for example, to perform physiological feedback/breathing Training, etc., or, further, can also be used for physiological stimulation, for example, the above-mentioned various auditory stimulation, and, since sound emitting elements can be set on both sides, it can also be implemented as using the above-mentioned binaural beat frequency method for physiological stimulation.

Therefore, under this framework, not only can obtain EEG signals and/or perform electrical stimulation, but can also provide audio and/or perform auditory stimulation. In addition, it is a common earphone form, and the user acceptance is quite high, which is very Choice with advantages.

And such a form, as long as it is made of soft and comfortable materials, is quite suitable for use during sleep. During sleep, by detecting EEG signals to understand brain activity, for example, rapid eye movement, deep sleep, etc., in addition to providing music that helps sleep, it can also be used to determine various effects on the brain. Stimulation, such as electrical stimulation, auditory stimulation, etc., and as mentioned above, the stimulation applied to the human body has the effect of improving/inducing the sleep state. Therefore, through such a configuration, the above-mentioned various stimulation methods will be achieved naturally, which is quite It has advantages; and further, other physiological sensing elements can also be added to obtain other physiological signals. Set other electrodes to obtain physiological signals such as electro-oculogram, electromyography, and electrodermal signals, or add a microphone to obtain information such as breathing conditions, snoring, and apnea (Sleep Apnea) events. It helps to understand sleep conditions in more detail, and, in addition to adjusting physiological stimuli, physiological signals can also be recorded for sleep diagnosis and analysis.

In addition, advantageously, based on the detection of EEG signals and/or other physiological signals, before performing electrical stimulation and/or resonant stimulation, the physiological state can be understood by observing the physiological signals, and then used as an indicator of whether to stimulate or not. Basis for decision, and/or basis for which stimulus to perform.

Among them, if the purpose of stimulation is to relax, improve concentration, change mental state, change/induce sleep state, change brain state, for example, cognitive state (cognitive state), etc., you can first observe brain waves or other physiological The signal is used to know whether the physiological state is in a stable physiological state, so as to determine whether stimulation can be started, and/or which stimulation is more suitable to be performed, which can help to achieve the stimulation effect more quickly.

For example, by observing the brain waves, it can be known whether the user is currently in a state of relaxation or tension. For example, if the α wave is dominant, it means that it is in a relatively relaxed state, and if the β wave is dominant, it means that it is in a tense state; on the other hand, if the If there are other physiological sensing components, other physiological signals can be used to understand the user's physiological state. For example, the optical sensor can obtain the user's heart rate, and use the RSA phenomenon to obtain the user's respiratory rate. Knowing the activity of the autonomic nervous system, and/or observing the coherence between heart rate and breathing, etc., which can represent whether the user is in a stable physiological state.

Through such prior observation, the stimulus can be executed in the most effective situation by setting preset conditions in advance. For example, if the observation is brain waves, the observation can be continued for a period of time or Whether the energy distribution in a specific frequency band is stable or whether the energy peak value is consistent between multiple segmented times. If the heart rate is observed, the heart rate, respiration rate, heart rate variability, and the coherence between heart rate and respiration can be observed. Whether sex, etc. fall within the preset range.

And further, if the user is in an unsuitable physiological state, for example, when a relatively unstable physiological state, the user can also be placed in a physiological feedback and/or breathing guidance/breathing training program as described above. After a more stable and relaxed physiological state, resonant stimulation/electrical stimulation is performed to make the effect of the overall procedure more significant. So there are possibilities, no limits.

This determination process can be implemented on a wearable device, or after the physiological signal is transmitted to an external device, and then executed by the external device, for example, the physiological signal is transmitted to the mobile phone through wireless transmission, and the application program in the mobile phone Calculate and decide whether to deliver a stimulus, and what kind of stimulus to deliver.

Here, it should be noted that although the above-mentioned stimuli are mainly about the structure of glasses, as is well known to those skilled in the art, the structure of glasses is a type of head-mounted structure, so all the above-mentioned contents are also applicable Applied to a device based on a head-mounted structure, whether it is used to obtain physiological signals or perform stimulation, it also falls within the scope of the present invention.

Another common application is as a human machine interface (HMI, Human Machine Interface). For example, it can analyze the user's intention (intention) by detecting EEG signals, or detect the user's physiological changes, and then By comparing with an instruction comparison table, it is converted into an operation instruction to control the device combined with the man-machine interface, or remotely control the external device. In recent years, such a man-machine interface combined with physiological feedback has also been applied to games, for example, allowing users to train concentration through the presentation of games.

Since the sensor according to the present invention is in the form of earwear or glasses, it is also suitable for use as a human-machine interface, and in the case where the detected physiological signals include EEG signals, eye movement signals, myoelectric signals, heart rate sequences, etc. , there are several possible ways that can be used to generate instructions.

For example, but not limited to, since the proportion of α waves in the brain waves changes greatly with the action of closing and opening the eyes, generally speaking, when the eyes are closed, the proportion of α waves will increase significantly , Therefore, it can be used as the basis for generating instructions; or, the electromyography signal (EMG) can distinguish whether the muscle is contracted to apply force, and the order can be issued through the occlusal force of the left and right teeth respectively; or, through the heart rate sequence The resulting RSA phenomenon can obtain the respiratory rate, so instructions can be issued by changing the breathing behavior.

In addition, when electrodes are provided on the frame unit to contact around the eyes, such as the bridge of the nose, the root of the mountain, the area between the eyes, and/or the upper and lower edges of the orbit, the movement of the eyes can be detected and the electro-oculogram (EOG) can be obtained. ), and it is also possible to detect the movements of the left and right eyes separately by setting multiple sets of electrodes, so that instructions can be issued through the movements of the eyes. Blinking speed/frequency, eye opening/closing actions, and the time interval between opening and closing eyes, etc., while eye movements include moving to the left and right, or rotating clockwise, etc., so through the above-mentioned various actions , they can be used as different instructions, for example, you can blink two eyes at the same time to turn on/off the device and/or activate a certain function of the device, such as physiological signal measurement, information provision, image/sound provision, etc.; or, right Blinking means input (ENTER), blinking the left eye means canceling (CANCEL), blinking one eye or both eyes several times in succession means jumping out (ESC), in addition, you can also use the time to open or close the eyes to give instructions; or Yes, turn the eyeball to the right to indicate the next page, and turn the eyeball to the left to indicate the previous page, etc.; or, different commands can be achieved by combining multiple eye movements, so it is not limited and can be customized according to actual needs There are different definitions.

However, because people usually have natural movements of blinking and eyeball movement, other response conditions can also be combined to make the command issue more smoothly. For example, a prompt unit can be used to generate a message to let the user For example, a vibration module can be installed on the structure of the glasses to interact with the user through vibration messages, for example, the vibration message can be used to inform the user It has entered the state of receiving instructions, so that the user knows that the eye movement can be started, and then input instructions; or, the vibration message can be used as a confirmation notification that the input has been completed after the user completes the eye movement, or implemented as the following The vibration message notifies the user that the command has been received and needs to be further confirmed whether to execute it. At this time, the confirmation can be performed by performing the same action or the specified action again; Or, and interact with the user, and through such a method, the entire operation process will become easier and more convenient.

Alternatively, motion sensing elements, such as accelerometers, gyroscopes, and magnetic sensors, can also be used to detect body motions to issue instructions together with glasses motions, such as dynamic head motions, such as nodding and shaking etc., or static posture changes of the head, such as raising the head, lowering the head, or different tilt angles, etc., or hand movements, for example, the motion sensing element can be set on the wrist-mounted structure or the finger-mounted structure to Knowing a specific gesture, or changing the static posture of the hand, or, further, cooperating with each other to obtain more combinations, are all suitable choices.

For example, the confirmation of the executed eye movement can be confirmed by nodding, shaking the head; or, in the case of simultaneous blinking to activate/deactivate the device, the activation/deactivation command can be distinguished by raising the head/lowering the head, or, After starting a function of the device with eye movements, the function can be operated with gestures. For example, after starting a browser with eye movements, gestures can be used to browse webpages, etc. There are various combinations possible.

Of course, it is also possible to combine eye movements with other physiological signals, such as the above-mentioned EEG signals, EMG signals, heart rate, breathing behavior, etc., or choose a suitable combination from various physiological signals and cooperate with each other to execute Instructions, so that not only more instructions can be combined, but also the execution of instructions is easier, so there is no limit.

In this way, by using the glasses structure as a man-machine interface, there can be many operational applications. For example, when the glasses structure is implemented with an information providing unit, for example, as mentioned above, there is a sound element that can play audio , for example, mp3 sound files, etc., when there is a display element that can provide images, you can control the playback of music, videos, etc. through instructions, for example, start/stop, pause, fast forward/backward, etc. When the radio element is used, it can be used to control the connection and hang up of the call, or, when the glasses structure is equipped with a camera/video camera, it can be used to control actions such as taking pictures, starting/stopping photography, and zooming in/out. Here, as mentioned above, there are various options for setting the information providing unit. For example, it can be set on the temple on one side and communicate with the physiological signal acquisition unit on the other side through wired or wireless communication. The method of communication can be changed according to the actual implementation method.

In particular, such an example is just in line with the use requirements of today's common AR or VR glasses. For example, AR or VR glasses usually have sound and image providing functions, such as music stored on the glasses or from an external device. Or images, so as long as the concept of the present invention is used to issue instructions through eye movements, the use will be more natural and convenient.

Furthermore, it is also used to remotely control various devices in general daily life, such as mobile phone photography/photography, e-book browsing, computer operation, such as web browsing, remote control of home appliances such as TVs, and slide control during presentations. Man-machine control, etc., have quite a lot of application possibilities and are very advantageous.

Here, it should be noted that the above-mentioned embodiments using various physiological signals as instructions are not limited to being used alone, and can also be used in combination according to actual needs. In this way, not only can more types of instructions be combined , and make the scope of application wider.

To sum up, the present invention utilizes the metal strand structure in common eyeglasses for electrical conduction in the process of physiological signal extraction, so that the eyeglass structure can obtain electrophysiological signal acquisition without changing the appearance of the frame unit. Moreover, the present invention also proposes the possibility of obtaining electrophysiological signals through a single temple, and also allows ordinary glasses without metal parts to obtain electrophysiological signal acquisition functions simply by replacing the temples.
