Description

Smart reading glasses

The present invention relates to the technical field of glasses, and in particular to a pair of smart reading glasses that can automatically turn on the lighting when the user gets out of bed after wearing the glasses.

Falls are common accidents in daily life, and they are more frequent in the elderly. For example, people over 65 years old are the most at risk of death from falls. With the occurrence of falls, various injuries will occur to the human body. General physical injuries such as abrasions, musculoskeletal system sprains, strains and fractures and other high-risk factors will cause serious injuries to the elderly. 20 to 30% of the elderly who fall will suffer moderate or above injuries, resulting in reduced mobility and even affecting the ability to live in daily life. Therefore, special personnel need to be provided for additional care, increasing medical and social costs.

Among them, some studies have pointed out that in addition to physical injuries, elderly people also suffer psychological injuries from falls. After falling, the elderly are afraid of falling again, so they will cognitively restrict their daily life situations that are common with falling in the hope of avoiding falling again. However, this not only causes a decline in the quality of life, but also reduces daily life activities, leading to the deterioration of various body functions, increasing the risk of falling again.

Among them, more than 80% of the elderly over 80 years old need to go to the toilet three times a night. When they get up to go to the toilet at night, they usually have to get out of bed in the dark or in very poor lighting conditions to find things such as slippers and/or need to hold on to the wall or walker to find the light switch, and then walk through the corridor and other spaces to reach the toilet. It can be seen that getting up to go to the toilet during sleep is the time when most elderly people fall, so how to protect the elderly from falling during this period is an important issue.

Please refer to Figure 1 and Figure 2 together. Figure 1 is a schematic diagram of the structure of the first implementation of the smart reading glasses of the present invention. Figure 2 is a schematic diagram of the block structure of the first implementation of the smart reading glasses of the present invention.

As shown in the figure, the smart presbyopic glasses 1 of the first embodiment of the present invention include a lens body 10, two light-emitting units 21, at least one first sensor 31, a second sensor 32, a power supply unit 40 and a processing unit 50.

The eyeglass body 10 may be composed of technical means or components such as presbyopic glasses that are well known or commonly used by the general knowledgeable person in the relevant technical field, and has a frame portion 11, and the frame portion 11 is provided with two presbyopic lenses 13 corresponding to the user's eyes. In addition, the two sides of the frame portion 11 are respectively connected to a leg portion 12 that can be bent and stored. By the way, the frame portion 11 and the leg portion 12 may be provided with a storage space at the required position to accommodate components such as the light-emitting unit 21, the first sensor 31, the second sensor 32, the power supply unit 40 and the processing unit 50.

The light emitting unit 21 may be a light emitting diode, and the two light emitting units 21 are disposed in the lens frame 11 and adjacent to the lens leg 12. It is worth mentioning that the eyeglass body 10 includes two light guides 14. The two light guides 14 are disposed respectively corresponding to the two light emitting units 21, and the light guides 14 at least surround one side of the light emitting unit 21 in the direction between the two sides of the lens frame 11 (referred to as the inner side of the light emitting unit 21) and one side of the lens frame 11 in the direction below (referred to as the lower side of the light emitting unit 21). For example, the light guide portion 14 may completely surround the light emitting unit 21 or only surround the inner side of the light emitting unit 21 and the lower side of the light emitting unit 21. In this way, the light source of the light emitting unit 21 is prevented from interfering with the user. In addition, the light guide portion 14 may preferably be a structure with a diameter gradually increasing from the lens frame portion 11 to the front of the lens frame portion 11; for example, the light emitting unit 21 is recessed a distance from the surface of the lens frame portion 11, and the light guide portion 14 is a concave cavity with a diameter gradually increasing from the lens frame portion 11 to the front of the lens frame portion 11; for another example, the light emitting unit 21 is aligned with the surface of the lens frame portion 11, and the light guide portion 14 is a convex portion with a diameter gradually increasing from the lens frame portion 11 to the front of the lens frame portion 11. Preferably, the light guide portion 14 may be further configured as a lens or provided with a reflector so that the light source of the light emitting unit 21 can be guided toward the front of the eyeglass body 10.

Among them, at least one first sensor 31 is arranged at the foot of the glasses 12 and is located on the side facing the user. In this embodiment, a first sensor 31 is used as an exemplary state. The first sensor 31 can be a light blocking sensor, a temperature sensor or a distance sensor, etc., which is configured to sense the user's wearing and generate a wearing signal 311. For example, when the user wears the smart presbyopic glasses 1 of the present invention on the face, the first sensor 31 senses light blocking, close distance or temperature change and generates a wearing signal 311. Among them, the second sensor 32 can be a light sensor, which is arranged on the glasses body 10, and the second sensor 32 is configured to sense the ambient brightness and generate a turn-on signal 321.

The power supply unit 40 may be a disposable battery or a rechargeable battery such as a lithium battery, which is disposed in the eyeglass body 10 and configured to supply the power required for the operation of the smart reading glasses 1. Incidentally, the smart reading glasses 1 of the present invention may include a charging transmission interface such as TYPE-C or a wireless charging interface and related power control circuits, which are well known to those with ordinary knowledge in the relevant technical field and will not be elaborated here.

The processing unit 50 may be a central processing unit (CPU), a microcontroller unit (MCU), a microprocessor, a programmable controller, an application specific integrated circuit (ASIC), an arithmetic logic unit (ALU), a complex programmable logic device (CPLD), a field programmable gate array (FPGA), a single chip system (Soc) or other similar components or a combination of the above components. The processing unit 50 may have a storage or a register, which may be a random access memory (RAM), a read-only memory (ROM), such as an electronically erasable programmable read-only memory (EEPROM), etc. The processing unit 50 is disposed in the eyeglass body 10 and electrically connected to the two light emitting units 21, the at least one first sensor 31, the second sensor 32 and the power supply unit 40. The processing unit 50 controls the two light emitting units 21 to emit the first color light source 211 toward the front of the eyeglass body 10 according to the wearing signal 311 and the opening signal 321. It is worth mentioning that in different embodiments, the number of the first sensors 31 can be two. When the number of the first sensors 31 is two, the processing unit 50 can control the two light-emitting units 21 to emit the first color light source 211 when receiving the wearing signal 311 and the opening signal 321 of only one of the first sensors 31; or, the processing unit 50 can control the two light-emitting units 21 to emit the first color light source 211 when receiving the wearing signal 311 of the two first sensors 31 at the same time and the opening signal 321.

That is to say, when the smart reading glasses 1 of the present invention sense that the user wears it on the face and the ambient light is insufficient, the two light emitting units 21 of the smart reading glasses 1 of the present invention will emit the first color light source 211 toward the front of the glasses body 10. The smart reading glasses 1 of the present invention can use the second sensor 32 to sense that the ambient light is insufficient and when it is worn on the face, the two light emitting units 21 are turned on for lighting, so that the user can find assistive devices such as slippers or crutches, and can provide lighting to avoid being tripped or injured by collisions while walking, thereby greatly reducing the risk of falling.

Please refer to Figure 3 and Figure 4 together. Figure 3 is a schematic diagram of the structure of the second embodiment of the smart reading glasses of the present invention. Figure 4 is a schematic diagram of the block diagram of the second embodiment of the smart reading glasses of the present invention. In this embodiment, the components with the same component symbols have the same or similar configuration and operation as the aforementioned embodiments, and the same or similar parts will not be repeated here.

As shown in the figure, the smart reading glasses 1 of the second embodiment of the present invention include a body temperature sensor 33. The body temperature sensor 33 may be a technical feature or technical means similar to a forehead thermometer, which is arranged on the side of the lens frame 11 facing the user, and correspondingly located between the two eyes of the user. The body temperature sensor 33 is electrically connected to the processing unit 50, and senses the user's body temperature in an upward direction from the lens frame 11 to generate a body temperature signal 331. When the processing unit 50 determines that the body temperature signal 331 exceeds a body temperature threshold value 51 (for example, 37.5°C, etc., which can be adjusted according to actual application), the processing unit 50 controls the two light-emitting units 21 to emit a second color light source 212 that is different from the first color light source 211. For example, the first color light source 211 may be white light or yellow light, and the second color light source 212 may be orange light or red light, etc. In different embodiments, the processing unit 50 may gradually change the color according to the difference between the body temperature signal 331 and the body temperature threshold value 51. For example, when the body temperature signal 331 is close to or slightly greater than the body temperature threshold value 51, the white light or yellow light is changed to orange light, and when the body temperature signal 331 is greater than the body temperature threshold value 51, the orange light is changed to red light, etc.

The smart reading glasses 1 of the present invention can use the body temperature sensor 33 to sense the physiological parameters of the user, so that the user or his family can quickly detect his physiological parameters and provide relevant care. It is worth mentioning that in different embodiments, the body temperature sensor 33 and the first sensor 31 can be integrated into a module and set at the foot of the glasses. It can use temperature changes to know whether the user is wearing the glasses and monitor the user's body temperature at the same time, thereby reducing components and manufacturing costs.

In addition, the smart reading glasses 1 include an indoor positioning unit 34 and a prompting unit 22. The indoor positioning unit 34 and the prompting unit 22 are disposed on the glasses body 10 and electrically connected to the processing unit 50. The indoor positioning unit 34, for example, can be configured to generate an indoor positioning signal 341 by using wireless transmission technologies such as wireless local area network (WLAN), WiFi, WiMAX, Bluetooth network, etc. in conjunction with indoor positioning-related algorithms. The processing unit 50 stores indoor configuration diagram information 52. The indoor configuration diagram information 52 has a plurality of indoor areas 521, and part of the indoor area 521 is configured as a risk warning area 522, such as a toilet or other area prone to falling. The indoor layout diagram information 52 can be stored in the processing unit 50 by wired or wireless transmission, or the smart reading glasses 1 can be used in conjunction with an application (APP) to plan the indoor layout diagram information 52 by using the user wearing the smart reading glasses 1 and moving indoors, and then the user uses the application (APP) to set the risk warning area 522. When the processing unit 50 determines that the user is located in the risk warning area 522 according to the indoor positioning signal 341, the processing unit 50 controls the prompt unit 22 to send a prompt message 221, wherein the prompt unit 22 can be a sound unit to use sound or other methods to remind the user to be careful when walking in the risk warning area 522; or, the prompt unit 22 can be combined with the light unit 21, that is, only the light unit 21 is provided to use the light source color change or flashing of the light unit 21 to remind the user to be careful when walking in the risk warning area 522.

Furthermore, the smart reading glasses 1 include a prediction unit 35, which is disposed on the glasses body 10 and electrically connected to the processing unit 50. The prediction unit 35 generates a prediction light signal 351 according to the user's usage status on multiple dates. The processing unit 50 controls the two light units 21 to emit the first color light source 211 toward the front of the glasses body 10 at a time point corresponding to the prediction light signal 351 according to the prediction light signal 351. Preferably, the lumen of the first color light source 211 of the light-emitting unit 21 controlled by the processing unit 50 according to the predicted light-emitting signal 351 is less than the lumen of the first color light source 211 emitted by the light-emitting unit 21 controlled by the processing unit 50 according to the wearing signal 311 and the opening signal 321.

Among them, the prediction unit 35 can obtain the prediction light signal 351 by using data statistics. It is worth mentioning that in different embodiments, the smart reading glasses 1 can have a wireless transmission connection to connect to a server, thereby transmitting the usage status of multiple dates to the server, so as to use the machine learning algorithm on the server to build a model, and use the model to make predictions, etc., so as to improve the accuracy of predicting the time point of possible toileting, and the prediction becomes more accurate as the usage time increases.

By the way, the connection between the electronic components can be achieved by routing wires inside the frame 11 and the leg 12 and by using contact points or connecting wires at the connecting axis of the frame 11 and the leg 12. These are technical means that are well known or commonly used by people with ordinary knowledge in the relevant technical field, and will not be elaborated here.

The smart reading glasses 1 of the present invention use the prediction unit 35 to predict the time point at which the user is likely to get up and go to the toilet under the user's usage conditions on multiple days, thereby generating the prediction light signal 351, and then The processing unit 50 is caused to control the two light-emitting units 21 at a time point corresponding to the predicted light-emitting signal 351 according to the predicted light-emitting signal 351 . With this, users can avoid situations such as searching for glasses in the dark when they wake up. Moreover, the brightness of the light emitted during prediction is smaller, which can avoid disturbing the user's sleep due to excessive brightness when the user does not wake up at the time point corresponding to the prediction light-emitting signal 351 .

The above description is for illustrative purposes only and is not intended to be limiting. Any equivalent modification or change made to the invention without departing from the spirit and scope of the invention shall be included in the scope of the patent application attached hereto.
