Description

Provide a method for patients to visually request assistance information

The present invention relates to the user interface (Eye-Control) technology, and more particularly to a method of providing a patient with visual assistance request information.

A patient means a subject who is caused by a physical injury or is suffering from a disease, whether or not he is hospitalized, usually lying on the bed for treatment or recuperation. Some patients may be unable to speak because of a condition, or they may not clearly articulate or direct to a health care provider, caregiver, or family member, such as a bodyache, itching, or discomfort, with a spoken or physical gesture.

There is a rare form of gradual freezing human disease, the full name of "Motor Neuron Diseases" (MND). In patients with this condition, the body will gradually become unable to move at the beginning, as if the body is frozen; about three years after the diagnosis, it will begin to have difficulty swallowing, eating, and the tongue is weak, and gradually Unable to speak at the normal speaking speed, causing communication obstacles. In addition, for example, a patient who has performed a gas cut is not easy to speak with, but it is also a challenge in communication.

In order to improve the above problems, the more advanced technology in the market already has visual operation aids with built-in eye tracking devices, which can provide patients with information on eye contact to request assistance. Among them, the visual operation is also called Eye-Control. Generally, the computer screen is used as the viewing interface of the patient's eyes. The computer screen will display the phonetic symbols, English letters and numbers, etc. for the eyes to stare (Gazing) and then point. The selected character block is used by the patient to express the demand assistance information by means of eye typing. but, If a patient (for example, a patient with gradual freezing disease) is in urgent need, such as going to the toilet or suffering from a certain pain, it takes a long time to apply the above-mentioned eye-control typing method, which is very difficult in this process. It is conceivable.

On the other hand, in the case of a normal person, it is quite easy to use a finger to operate the keyboard and the mouse to input an instruction; however, the eyes are gazing at the character block in the screen interface to operate a key press (key down/ The click event is limited by the fact that the eye is not easy to intuitively press; therefore, a lot of eye control input methods have been developed to allow the eye control to produce a click event.

Most of the consensus among the parties is to generate a press event with dwell time. However, if the human eye gaze at something for too long (>1000ms), the eyes are easily tired; if the gaze time is too short (<300ms), the eye tracking device is not easy to capture the pupil position. It is also known that the gaze time of typing with the eyes falls on the average of 400~1000ms, which is accelerated by the continuous learning relationship. Some people use the glance method, the speed of people's glance is quite fast (<100ms), the average gaze time is about 100-600ms, the user uses a specific order of glance to obtain the user's instructions; however, this method of glance, The user has to practice, remember, and even practice the imagination. It is not a very intuitive method. Compared with the patient, there is still room for improvement in the sensitivity and convenience of the eye control operation.

In view of this, the present invention aims to improve the traditional eye-controlled typing method, which requires more operation time, and for the patient suffering from the pain of the patient, when the demand assistance information is released, it is obviously unsatisfactory and has convenient operation and owing. Good question.

Further, one of the objects of the present invention is to abandon the operation mode of the traditional eye-controlled typing, and to create an interface that is easy to use the eye to control the selection command based on the common instruction required to collect the patient's course in advance, and to match the text-to-speech system. (TTS), pre-translated (multi-language), body map (Body Map), etc. as interface options, allowing patients to quickly control the information required by clicking on the required instructions.

In order to achieve the above object, a preferred embodiment of the present invention is to propose A method for providing a patient with visual assistance demand information, comprising: sequentially performing: (1) setting a plurality of eye control instruction sets according to a common requirement of the patient, the plurality of eye control instruction sets having a hierarchical and classification association; (2) constructing a plurality of pressed event tiles and a plurality of user interfaces, wherein the plurality of pressed event tiles are edited according to the association of the plurality of eye control command sets and classifications, The plurality of user interface layers are layered to reveal the plurality of classified pressing event tiles, and the plurality of user interfaces are sequentially displayed on a display screen; (3) applying the display screen to one of the tracking devices Detecting that the patient's pupil gaze at each of the plurality of user interfaces to generate a page turning signal or a trigger signal; the page turning signal commands each user interface of the layer to turn pages, The trigger signal command a prompting unit generates a demand assistance information of the patient; wherein the plurality of pressed event tiles include at least one body part pattern instruction, and the demand assistance information includes at least sound release.

In a further implementation, the plurality of pressed event tiles are included in a user interface of each single layer to display a plurality of specific operation instruction tiles and a plurality of specific requirement instruction tiles, and the body part pattern instruction Belong to one of the specific demand instruction tiles. among them:

Each of the plurality of specific operation instruction blocks 31 and the plurality of specific requirement instruction blocks 32 may be respectively attached with a specific event text (or an instruction name) and attached to a specific color display for visual resolution (as shown in FIG. 3a and FIG. 3b, Figure 3d, Figure 3e, detailed later.

In addition, the tracker 11 shown in FIG. 2 can display a line of sight cursor 13 (shown by a dotted circle in FIG. 3) in each of the user interfaces 20 when detecting the gaze position of the patient's eye 12, the line of sight. The cursor 13 can be designed to a particular geometric shape or a particular symbolic representation, and the line of sight cursor 13 can follow the gaze position of the patient's eye 12 in each of the user interfaces 20 and stop at a particular tile position.

In addition, as shown in FIG. 3, the present invention is planned on each page user interface 20, particularly in a blank area between the plurality of specific operation instruction blocks 31 and a plurality of specific demand instruction blocks 32. There are a plurality of gaze venting areas 33; and a part of the specific operation instruction block 31 (for example, the emotion expression instruction 31b shown in FIG. 3a, the virtual attendant expression instruction 31e) and a part of the specific requirement instruction block 32 (for example, The diet instruction 32d, the medication instruction 32e, and the personal hygiene instruction 32f) shown in Fig. 3a can also be located in the gaze venting area 33.

Thereby, the plurality of gaze venting areas 33 can reveal pre-built translated instructions or guiding words (for example, Chinese, English, Indonesian, Vietnamese, etc.) to guide the patient's eyes to gaze related operational states. The plurality of gaze venting zones 33 can also provide an area for the patient to rest slightly as the line of sight of the eye when the pressing event is not operated. It should be particularly noted that the number and location of the specific operation instruction block 31, the specific requirement instruction block 32, and the gaze venting area 33 may be based on each user interface 20 Increase, decrease and replace the actual configuration requirements.

On the other hand, the present invention focuses on improving the accuracy of the eye control operation pressing the event block 30, and in particular, a plurality of array dots 21 (shown in FIG. 3) are arranged in each of the user interfaces 20 as corrections. Auxiliary reference point for the patient's eye gaze position.

Referring to FIG. 3a, a preferred embodiment of the user interface 20a as a front page is disclosed. When the plurality of press event blocks 30 are attached to the color display, the dots 21 located in or behind the block 30 are illustrated. The plurality of pressed event tiles 30 may be covered, and the dots 21 may be exposed in a blank area around the plurality of pressed event tiles 30.

As shown in FIG. 3a, it is also revealed that a plurality of specific operation command blocks 31a to 31e can be respectively disposed at the peripheral edges of the user interfaces 20 in different color blocks as required by the disclosure. It is a service bell command 31a, an emotion expression command 31b, a sleep mode command 31c, a page turning command 31d, a virtual attendant expression command 31e, or other configuration areas such as a body sense command, an interface zoom command, etc., for patient eye control. Click (ie, press the button).

It is further revealed in FIG. 3a that the plurality of specific requirement instruction blocks 32a to 32f can be respectively arranged in the central area of the first page (user interface 20a) with different color blocks, for example, as the daily life instruction 32a, a special situation command 32b, a body sense command 32c, a diet command 32d, a drug command 32e, a personal hygiene command 32f, and the like, and a configuration area of the demand assistance command; in addition, a plurality of specific demand instruction blocks 32 may also serve as the above-mentioned demand instruction. The configuration area of the prefix language (for example, I want, I need, feel, no), in particular, including the above-mentioned body feeling command 32c, a body part pattern instruction 32g is displayed on the sub-layer user interface 20b (as shown in the figure). 3b) for the eye control of the patient (ie, the operation is pressed).

Continuing with Figure 3b, a preferred embodiment of the sub-layer user interface 20b shown after clicking the body sensation command 32c in Figure 3a is disclosed. Further, the first page command 31f, the open call command 31g, the return (or previous page) command 31h, and the like belonging to the specific operation instruction block may be respectively configured in the user interface according to the operation requirement. At the peripheral edge of 20b, the body part pattern command 32g belonging to the specific demand instruction block can be disposed in the central area of the layer user interface 20b. In addition, the user interface 20b of the layer is divided into two. The upper gaze area 33a and the lower gaze area 33b are disposed on the upper layer (not shown), and the upper gaze area 33a is distributed. The home command 31f, the open call command 31g, the return command 31h, and the body part pattern command 32g are provided, and the lower gaze vent area 33b is provided with a text for explanation or guidance.

It should be further noted that the body part pattern command 32g shown in FIG. 3b includes a 3D body part enlargement pattern command 32g' and at least one 3D whole body pattern command 32g separated by display with additional visual feedback; the patient's eyes can first gaze and use The eye control flips the body part displayed by the 3D whole body pattern command 32g" so that the 3D body part enlargement pattern command 32g' can dynamically display the 3D whole body pattern command 32g', the guided body enlargement portion. In the embodiment shown in FIG. 3b, the patient's first eye control line cursor 13a is moved to select the human hand palm disclosed in the 3D whole body pattern command 32g", and then the body part enlargement pattern command 32g' can dynamically display the palm of the hand. In the enlarged view, the patient can further move from the eye-control sight cursor 13a in the illustration of the body partial magnification pattern command 32g' to zoom and click on the finger portion of the palm where the palm is actually painful.

Referring to FIG. 3c again, the periphery of the body part enlargement pattern command 32g' is provided with a direction command block 320g', a zoom instruction block 321g', and a rotation instruction block 322g'.

Wherein, the animation guide of the body part derived from the body part pattern instruction 32g, and the text block (or instruction) guidance of the degree of discomfort such as itching or pain may be adapted to the specific operation instruction block 31a and the specific requirement instruction block. 32a, 32b, 32d, 32e, 32f is expected to increase or decrease the actual situation of the patient, or replace it with a non-animated text or voice command block, which is within the scope of application of the present invention.

Step S3: Detecting a press event.

Referring to FIG. 4, a program diagram for detecting a press event according to the present invention is disclosed, and a software program compiled from a plurality of eye control instruction sets shown in Table 2 is used to detect a pressing event of a patient's eye control operation (ie, click to select The process consists of: first gazing at the patient's pupil The demand page (for example, the home page) of the plurality of user interfaces 20 is used for eye control to select the desired pressing event block 30; then, the software program selects the instruction of pressing the event block 30 according to the patient's selection. A page flip signal 40 or a trigger signal 50 is generated.

When the patient's eye control selects the desired press event block 30 to generate the page flip signal 40, the software program will revert to the plurality of user interfaces 20 for page turning to command the layered user. The interface is displayed on the display screen; accordingly, the page turning action of the upper and lower pages can be performed back and forth, so that the patient can search and click the desired event type of the event block 30 layer by layer.

When the patient eye control selects the desired press event block 30 to generate the trigger signal 50, the software program commands a prompting unit 60 to generate a demand assistance information 61 of the patient; wherein the demand assistance information 61 can include The sound 61a and the text/graphic 61b form are sent to the medical staff, caregivers or relatives and friends. For example, when the patient eye control selects the service bell command 31a belonging to the specific operation command block (as shown in FIG. 3a), the software program generates a trigger signal 50 (as shown in FIG. 4) to command the prompt unit 60 to sound 61a, or sound. Request assistance information 61 in the form of 61a and text/graphics 61b is released to the public. The sound and text information may be at least one of voice or text in a software program setting or selected multi-language, and the sound also includes a non-speech voice.

Further, in FIG. 4, in the process of detecting the pressing event, there is a problem that the human eye sometimes has a line of sight error, and the eye control is not selected smoothly. In order to overcome this problem, the present invention proposes an embodiment as disclosed in FIG. 5, which illustrates that when the patient finds an error between the line of sight cursor 13a displaying the gaze position and the position of the pressed event block 30 to be gazed, the present invention can be utilized. The corner of the eye gaze at the dot 21a around the pressing event block 30 as the gaze position of the correction error, so as to correct the patient's sight cursor 13a to the center position of the pressing event block 30 to be gazed, thereby improving the software program. Check the appropriate rate of the press event.

Secondly, since the human eye's line of sight moves at a very fast speed, it is extremely prone to eye jitter when the line of sight moves. In this regard, the present invention also proposes an improvement. Please refer to FIG. 6 to illustrate the line of sight cursor 13b when following the patient's line of sight. When only the edge of one end of the event block 30 is pressed to generate the overlapping area A, the pressed event block 30 can be detected by the software-programmed sensing circuit (known in the art, so no further description). The overlapping area A is such that each of the pressing event blocks 30 can automatically adsorb the line of sight cursor 13b to the center position of the pressed event block 30 to improve the convenience of automatically positioning the sight line cursor 13b during the eye control operation, thereby improving the above. The problem of line of sight jitter.

In addition, because the eye control operation is not like the general hand and eye mouse, the pressing event is clearly generated, so the software program of the present invention is also equipped with the timing of the dwell time, so as to decide whether to detect the pressing. event. Further, the present invention particularly enhances the mechanism of visual feedback, and in the gaze venting area of the desired user interface, displays a schematic view of the countdown to facilitate the patient to know the action of the eye-controlled press event that he is operating. It is true.

As shown in FIG. 7, the reciprocal logic diagram of the operation pressing event of the present invention is disclosed, indicating that when the patient's eyes gaze at a user interface 20c, a line of sight cursor 13c is displayed on the user interface 20c, and the line of sight cursor 13c follows the patient. The line of sight moves to the pressed event block 30 to be selected. In this process, according to the line of sight error correction function of the dot 21a shown in FIG. 4 and the adsorption function of the overlapping area A shown in FIG. 5, the line of sight cursor 13c is fast. Locked at the center position of the pressed event block 30 to be selected, and then enters the system's preset countdown time, for example, the reciprocal of 2 seconds, 1 second, and 0 seconds is sequentially performed, and then the pressed event block 30 is executed immediately. Instructions. The state of the last 2 seconds, 1 second, and 0 seconds can be dynamically displayed in the gaze venting area 33 of each user interface 20 by a timed block 34 or an animation with a reciprocal number.

According to the description of the above embodiments, it should be understood and confirmed that the present invention deletes the typing interface, and changes the preset command, converts it into a command button on the computer interface, and adds a 3D body part pattern (or 3D body map). It allows the patient to clearly identify the location of physical discomfort, thereby shortening the time for patients to express demand information. In addition, the present invention also applies functions such as instant voice pronunciation and subtitle prompting, so that the patient and the caregiver, the caregiver or the family can quickly understand the patient's needs even if the language is not available, thereby assisting in dealing with the patient's body. Disease Pain problem. Furthermore, the cost of applying the hardware such as a computer or a display screen to the present invention is relatively low, and is an accessory cost that can be generally affordable to ordinary people.

It must be specifically stated that the term "event" in the description of the above embodiments can be interpreted as "instruction". The term "click" can be interpreted as "operational press" or "eye-control gaze". The term "tile" can be interpreted as "Icon". In addition, the term "patient" can be interpreted as "user". Therefore, the present invention is not intended for use by, for example, a patient suffering from gradual freezing of a person; in other words, a normal person can also use it; however, please note that the present invention is not Used for chatting, but used to quickly ask for help, shorten communication or patients endure painful time.
