  Hereinafter, embodiments of the present invention will be described in detail for each example.

1 and 2 are explanatory views showing an example of the tools of Patent Documents 1 and 2. FIG.
The tools introduced below are those published by the present inventor based on patent documents and those that have been filed separately from the present application.
As described above, in Patent Document 1, the degree of pain is expressed by the number and size of protrusions. The pain tool 12 to the pain tool 17 shown in FIG. 1 are examples of tools that quantitatively express seven levels of pain.

  The basic structure of this tool is a sphere. The structure was such that many protrusions protruded around the sphere as the pain was felt. Ask the subjects to choose something that shows their level of pain. By picking each one up, you can express the degree of pain in one of seven levels, like yesterday and today.

  In Patent Document 2, the degree of stiffness of the joint is expressed by the degree of deformation of the rod. The basic structure of this tool is a straight bar. The bending tool 21 to the bending tool 27 shown in FIG. 2 are examples of tools that express the degree of stiffness in seven stages. For example, when the joint is difficult to bend due to rheumatism or the like, the person who chooses the degree of stiffness is selected. The test subject can be expressed in any of the seven levels, such as the last time he has bent this far and this time he has bent this much.

FIG. 3 shows an example of a tool already filed by the applicant.
This tool expressed the degree of stagnation by the number of protrusions on the inner surface of the hollow sphere. The stagnation tool 31 to the stagnation tool 35 shown in FIG. 3A are examples of tools that express the degree of stagnation in five stages. In this example, a hollow sphere divided into two as shown in FIG. As the degree of stagnation increases, the number of protrusions 26 increases. The subject can express the degree of itchiness this time this time and this time this time.

  All of the tools in the above examples can express their own emotions using vision and touch while actually touching the hand. It was found that it is easy to express psychological quantities quantitatively for children who are difficult to express in words. On the other hand, it was examined whether the same thing can be done with the tablet-type computer which has spread widely recently.

  However, it has been found that just selecting the tool image displayed on the display as it is is less real and the accuracy of the obtained data is lower than when the tool is actually selected by hand. In the present invention, the subject himself / herself can freely change the image of the tool with his / her finger to compensate for the non-solid object. In addition, by combining videos and coloring, the subjects can more easily convey their feelings.

  Similar to the above example, the apparatus of the present invention expresses a change in psychological quantity by the degree of deformation of the basic structure of the article. Image data indicating the structure of the article is displayed on the display of the computer, and the movement of the finger touching the display is detected. The computer storage device stores in advance image data indicating the basic structure and a large number of image data in which the degree of deformation of the basic structure is gradually increased. Depending on the direction in which the finger moves and the distance that the finger touches the display, any image data obtained by modifying the basic structure is selected and displayed. In the following embodiments, a tablet computer is used. Hereinafter, this is simply referred to as a tablet 40.

(Tablet operation screen)
FIG. 4 shows an operation screen for expressing pain.
When the subject measures pain for the first time, the pain tool 11 (FIG. 1) having a basic shape is displayed on the display of the tablet 40 as shown in FIG. This indicates a state without any pain. Then, the finger 44 touching the display is swiped in the horizontal direction (X-axis direction). When the distance that the finger touches the display is short, as shown in (b), the pain tool 14 (FIG. 1) is displayed around the sphere, and the protrusion 20 having a medium size protrudes from the basic structure. become.

  On the other hand, when the distance that the finger touches the display is long, as shown in (c), the pain tool (17) is displayed, and a large protrusion 20 protrudes from the basic structure. In addition, the number of protrusions 20 has increased. When the finger 44 is moved in the direction opposite to the arrows (b) and (c), the size of the protrusion 20 is reduced, the number is reduced, and the opposite deformation is performed. The subject freely moves his / her finger while viewing this image, and determines the degree of his / her pain while viewing the change in the shape of the image.

  For example, when the user thinks that his / her pain is the extent shown in FIG. Thereby, the identification information of the image data selected by the subject is stored in the storage device of the tablet 40. As will be described later with reference to FIG. 7, the identification information of the subject, the identification information of the displayed image data, and the like are stored. When the subject has made this measurement in the past and examines how the degree of pain has changed since then, the previously stored image data is displayed on the initial screen. Using the image data of the initial screen as a starting point, the deformed image data is displayed on the display according to the direction in which the finger moves and the distance that the finger touches the display.

FIG. 5 shows an example in which a moving image is included in the basic structure.
For example, first, a still image of the pain tool 17 is displayed. Here, the direction of detecting the movement of the finger to be swiped is distinguished from the process corresponding to the movement. The horizontal direction with respect to the display is the X-axis direction, and the vertical direction is the Y-axis direction. Immediately before this state is reached, the subject swipes in the X-axis direction, and in the example of FIG.

  Here, the finger 44 touching the display is swiped in the vertical direction (Y-axis direction). When the distance that the finger touches the display is short, as shown in (b), the protrusion 20 is small and starts to vibrate. On the other hand, if the distance that the finger touches the display is long, as shown in FIG. In addition, you may make the protrusion 20 move so that it may expand or contract.

  In any case, when the protrusion 20 vibrates, it is possible to regard this as own pain and convey the emotion faithfully to a person. It is possible to convey a feeling closer to the actual feeling than when selecting still image data. Note that you can swipe your finger in any direction on the display. When swiping from the lower left of the display to the upper right, the protrusions increase and at the same time the protrusion amplitude increases. By tracing the display with your finger in various directions, you can find an image that can convey your psychology well, and you will be more interested.

FIG. 6 shows an example of changing the color of a part or the whole of the tool.
For example, first, using the color selection icon 48, the subject is allowed to select whether the color to be developed is red or blue. Of course, the color may be fixed or more types. For example, the color sample list is displayed by touching the tool for more than one second or touching a button called color change. You may specify a color in that state. Then, the tool is displayed on the display, and the distance that the finger touches the display by swiping is measured.

  When the swipe distance is small, a part of the protrusion is colored. If the swipe distance is large, more protrusions are colored. The degree of itchiness can be expressed by the number of colored protrusions. For example, when the red color is dark, itching is strong, and when the red color is light, it is determined that itching is small. Even in this case, the dynamic state in which the color density becomes thicker or thinner around a certain density is more effective for making the subject feel itchy. In addition, it is possible to perform measurement with higher accuracy when the subject himself / herself changes the concentration and selects the corresponding concentration, rather than selecting samples of several concentrations.

  With the tools as described above, the image displayed on the display of the tablet computer changes into various shapes depending on the operation of the subject's finger. Also, various movements or various colors appear. As a result, the subject is interested in selecting an image using a tablet computer, and can quantitatively convey the psychological quantity without using a three-dimensional structure tool. A process for determining the stage of the degree of pain based on the image data determined by the subject will be described below.

(Tablet features)
FIG. 7 is a functional block diagram of the tablet.
The apparatus of the present invention is configured by functional blocks as shown in the figure, for example. The tablet 40 includes an arithmetic processing device 50 and a storage device 52. The arithmetic processing unit 50 includes a display control unit 54, a contact distance measurement unit 56, a shift amount calculation unit 58, an image vibration control unit 62, an image color selection unit 64, a determination operation detection unit 66, and a psychological amount determination unit 67. ing. These are realized by a computer program that gives each function to the computer.

  The storage device 52 stores an image data group 68, a determination icon 70, a color selection icon 72, a psychological amount determination table 74, and determination data 78. The determination data is data including the subject identification information 80, the image data identification information 82, and the determination result 84.

  The display control unit 54 has a function of reading image data from the image data group 68 and displaying it on the display of the tablet 40. The contact distance measuring means 56 has a function of measuring a contact distance until the finger is released from the display after the finger touches the display. The shift amount calculation means 58 has a function of calculating the degree of change in shape corresponding to the finger movement distance with respect to the image data displayed on the display in the initial state. That is, it calculates how much the value of the boyer who selected the image data displayed on the screen is shifted. When the calculation result of the shift amount calculation means 58 is input, the display control means 54 reads new image data from the image data group 68 and displays it on the display.

  The image vibration control means has a function of reading out and displaying from the image data group 68 a moving image that vibrates or appears on the protrusion centering on the displayed image. The image color selection means 64 has a function of reading image data colored according to the contact distance of the finger from the image data group 68 and displaying it on the display. The determination operation detection unit 66 has a function of storing the identification information of the image data being displayed in the storage device 52 together with the identification information of the subject when the determination icon 46 displayed on the display is touched.

  As described above, the image data group 68 includes still images and moving images. The image data displayed on the display changes gradually according to the movement of the finger. The smoother this change is, the better the operability. Accordingly, a large number of still images are included in the image data group 68. Identification information such as a serial number is assigned to all image data. The display control means 54 selects image data with a pointer.

  In addition, when a moving image that vibrates the protrusion is displayed with a certain still image in an initial state, the corresponding moving image may be selected. Therefore, the moving image is also included in the image data group 68 with identification information. In addition, a process for continuously transforming image data by a program may be executed. In any case, it is only necessary to add identification information for identifying which stage of image data the image data displayed on the display is. The determination icon 70 and the color selection icon 72 are image data for displaying an icon on the display.

FIG. 8 is an explanatory diagram of the operation of the psychological quantity determination means 67.
When the determination icon 70 is touched, the identification information of the image data displayed on the display is acquired. The psychological quantity determination means 67 has a function of determining, from the image data identification information 82, for example, what level the pain level is in 7 levels in total. The psychological quantity determination table 74 is used for this determination. This is data in which determination results 84 corresponding to the image data identification information 82 are listed. By this process, the determination data 78 shown in FIG. 7 is generated. The determination data 78 is then analyzed by a doctor or the like.

(Computer program)
FIG. 9 is a flowchart of the computer operation of the example of FIGS.
First, the application is activated in step S11. Next, in step S12, subject designation processing is performed. That is, the identification information of the subject is input. In step S13, the history of the subject in the storage device is read. If there is a history, the identification information of the latest image data is read, and the initial screen display is performed with the corresponding image data (step S14).

  In step S15, a swipe operation is detected. When the swipe operation is performed, the process proceeds to step S16, and when the answer is no, the process waits. In step S16, the contact distance of the finger to the operation screen is detected. In step S17, it is determined whether or not the swipe line has an X-direction component. If the result of this determination is yes, the process proceeds to step S18, and if no, the process proceeds to step S19. In step S18, the number of protrusions is increased or decreased according to the swipe direction.

  In step S19, it is determined whether the swiped line has a Y-direction component. When the result of this determination is yes, the process proceeds to step S20, and when no, the process proceeds to step S21. In step S20, the process of increasing or decreasing the vibration of the protrusion according to the swipe direction is performed.

  In step S21, it is determined whether the determination icon has been clicked. If the result of this determination is yes, the process proceeds to step S22, and if no, the process returns to step S15. In step S22, identification information of the determined image data is acquired. In step S23, the psychological quantity is determined from the identification information of the image data, and the result is output to a display, for example.

FIG. 10 is a flowchart of the computer operation of the example of FIG.
In step S31, the application is activated. In step S32, a process for designating a subject is performed. In step S33, an initial screen is displayed. Up to this point, the processing is the same as that in FIG. Next, in step S34, color selection is accepted. Set for color development by subject's desired color.

  In step S35, a swipe operation is detected. When the swipe operation is performed, the process proceeds to step S36, and when the answer is no, the process waits. In step S36, the contact distance of the finger to the operation screen is detected. In step S37, it is determined whether the swiped line has an X-direction component. If the result of this determination is yes, the process proceeds to step S38, and if no, the process proceeds to step S39. In step S38, the number of protrusions is increased or decreased according to the swipe direction.

  In step S39, it is determined whether the swiped line has a Y-direction component. When the result of this determination is yes, the process proceeds to step S40, and when no, the process proceeds to step S41. In step S40, color density increase / decrease processing according to the swipe direction is performed. At this time, if the density of the color is dynamically increased or decreased around a certain density, it becomes easier to capture the emotion of pain. Step S41 and the subsequent steps are the same as the processing after step S21 in FIG.

(Experimental result)
FIG. 11 is an explanatory diagram of data showing a specific experimental example.
Here, the existing numerical evaluation scale was compared with the experimental data of the device of the present invention using a tablet, and its usefulness was confirmed. There are 4 test subjects, all 22-year-old men. A numerical evaluation scale marks a 10 cm long line segment without a scale. The scale is shown on the right side of the graph. The lower end corresponds to “no pain” and the upper end corresponds to “very painful”. The result is shown by a solid line. Judgment of the degree of pain by a tablet was made into 7 steps. A scale of 1-7 was displayed on the left side of the graph. The result is shown by a broken line. In addition, the subject was allowed to freely vibrate the protrusions. The vibration level is shown on the left scale. The results are shown by a one-dot chain line.

The experiment was performed in the following order.
1) I was asked to list five experiences of pain that I have experienced so far.
2) The degree of pain was shown on a numerical evaluation scale.
3) About the five pains listed by each subject, the degree of pain was judged by a tablet.
4) The subjects were asked how they felt better than the numerical evaluation tool (how well they expressed their pain). Subjects were evaluated on a scale of 1 (very bad) to 5 (very good).

  As a result of taking the average of the impressions, the average of the four people became 3.5. In particular, a good evaluation was obtained that “the stabbed pain was easy to express” in that the protrusions increased and decreased. On the other hand, the shape of the protrusion as shown in FIG. 3 was evaluated as “It is difficult to express dull pain or the like even if stimulating pain can be expressed”. In order to express dull pain, it was found that the shape of the protrusions should be more gentle. Therefore, it has been found preferable to add a function capable of selecting the shape of the protrusion. In addition, with regard to changes in shape, vibrations of protrusions, and changes in color, individual differences appeared in preferences for each subject. It was found that the selection could be adapted to the individual differences of the subjects.

  From the above experiments, the apparatus of the present invention is easier to grasp visually than numerical evaluation, and is based on the real model shown in FIGS. Compared to static tools, it is easier to convey various pain expressions. Moreover, various changes could be taken in and a versatile device could be realized.

FIG. 12 is a block diagram of an operation screen and an arithmetic processing system for expressing a pain state.
In this embodiment, an example will be described in which a pain state is determined by detecting the degree of pain, the type of pain, and the temporal change in pain. The tablet 40 shown in this drawing displays a window for expressing the degree of pain as a waveform. As shown in this figure, the subject expresses the state of pain he / she feels on the window by drawing a wave using the finger 44.

  When the test button 95 is tapped after drawing the wave, the tablet 40 vibrates the main body so as to correspond to the waveform drawn on the window. The arithmetic processing unit 98 and the storage device 99 of the tablet 40 for executing such operations are configured by functional blocks as shown in the figure, for example.

  The arithmetic processing unit 98 of the tablet 40 includes a data reading unit 100, a digitizing unit 102, an envelope acquiring unit 104, a vibration pattern generating unit 106, a vibrator driving unit 108, a single waveform detecting unit 110, and a periodicity determination. Means 112 are provided. The storage device 99 stores input waveform data 86, digitized data 87, envelope data 89, and basic waveform data 91 to 93.

  The data reading unit 100 has a function of reading input waveform data 86 drawn on the window of the tablet 40. The digitizing means 102 has a function of digitizing the read input waveform data 86. The envelope acquisition unit 104 has a function of analyzing the digitized data 87 and acquiring envelope data 89. The vibration pattern generation unit 106 has a function of generating a vibration pattern having a strength change corresponding to the envelope data 89. The vibrator drive unit 108 has a function of vibrating the tablet 40 with the vibration pattern generated by the vibration pattern generation unit 106.

  The single waveform detecting means 110 has a function of analyzing the input waveform data 86 and detecting one unit of waveform included therein. Further, the single waveform detection unit 110 has a function of determining which of the basic waveform data 91 to 93 corresponds to this one unit waveform. The periodicity determining unit 112 has a function of determining in what cycle a unit waveform is generated in the input waveform data 86.

FIG. 13 is an explanatory diagram of a specific example of each data stored in the storage device 99.
(A) is the input waveform data 86 obtained from the waveform drawn on the window of the tablet 40. (B) shows the result of digitizing the input waveform data 86. The horizontal axis of the input waveform data 86 is the time axis, and for example, the level of the input waveform data 86 is measured every quarter second. The digitized data 87 becomes effective data for analyzing the input waveform data 86 and further storing it in the storage device 99.

  (C) shows the envelope data 89 of the input waveform data 86. When the envelope data 89 is modulated by the vibration waveform 88 for driving the vibrator, the vibrator can be vibrated so as to change the intensity of vibration faithfully to the input waveform data 86.

  In addition, one unit of waveform 90 is extracted with a monotonically increasing portion and a monotonically decreasing portion included in the input waveform data 86 as a set. In the storage device, three types of basic waveform data A91, basic waveform data B92, and basic waveform data C93 are stored in advance. The basic waveform data A91 is used for determination of sharp pain, the basic waveform data B92 is not sharp but strong pain, and the basic waveform data C93 is used for determination of dull pain. It can be seen that one unit of waveform 90 shown in this figure corresponds to basic waveform data A91. What is necessary is just to normalize so that the width | variety and height of 1 unit of waveform 90 and basic waveform data A91 may be equalized, and to obtain | require the difference value of both numerical data, and to judge whether it is the minimum.

  The subject does not always draw the waveform of the figure faithfully to the temporal change in pain. If the phenomenon of abstract pain is expressed in the form of waves, there are cases where waves are drawn with the consciousness. Therefore, it is effective to extract a waveform of one unit, to determine the degree and nature of pain from its shape, and to determine the nature of pain from the degree of repetition of pain from periodicity. For example, it is determined that the degree of pain is A and that there is periodicity. The subject's feelings about the pain are obtained from the results of Example 1. By combining these, it is possible to objectively grasp the condition of the subject.

  Furthermore, the above data can be widely used for obtaining and analyzing the health condition of the subject. For example, it is possible to provide a function of storing the input waveform data 86 as image data or digitizing it into a storage device and then transferring it to a server or another computer via a network.

FIG. 14 is an explanatory diagram showing another method for determining the nature of pain.
In the above example, subjects were subjects who answered the question "What happens if the nature of pain is expressed in the form of a wave?" This embodiment, on the other hand, helps to determine the nature of the child's pain that can only respond to simple questions.

  On the display of the tablet 40 shown in (a) of the figure, a figure having the protrusion 20 described in the first embodiment is displayed. A test subject holds the protrusion 20 with a finger 44. Then, tell them to press hard when they feel pain.

  In (b), the side view when the finger | toe 44 touches the display screen 120 was shown. As shown in this figure, the area where the fingertip contacts the display screen 120 varies depending on whether the finger 44 is just touching the display screen 120 or when the finger 44 is strongly pressed against the display screen 120. The state is shown in (c).

  The contact surface 122 when the finger 44 is lightly pressed against the display screen 120 and the contact surface 123 when the finger 44 is strongly pressed against the display screen 120 will be compared. When the strength with which the fingertip is pressed against the display screen 120 is changed, the contact area between the fingertip and the display screen 120 changes depending on the degree of pain. When the test subject touches the protrusion 20 and changes the strength of pressing his / her finger according to his / her pain change, the temporal change in the degree of pain can be acquired as data by recording the change in the contact area. it can.

  In order to detect such a change in the contact pressure of the finger, a contact pressure detection means is provided. The above processing is possible with the known tablet 40, but if a sensor for directly detecting the contact pressure is newly attached to the upper surface of the display, the detection output can be used. (D) shows envelope data 89 corresponding to the temporal change of the degree of pain acquired by this method. If the vibration waveform 88 corresponding to the envelope data 89 is generated, the tablet 40 can be vibrated according to the nature of the pain, as in the above embodiment.

FIG. 15 is a functional block diagram of an apparatus for directly inputting a temporal change in pain.
A slider 128 is displayed at the center of the screen of the tablet 40. In addition, a start button 130, a test button 95, and an enter button 96 are displayed on this screen.

  The finger 44 is touched on the slider 128, and the temporal change in pain is represented by a waveform. For this operation, the arithmetic processing unit 98 is provided with a graph constant velocity moving means 136, a slider position detecting means 138, and a drawing means 140. The storage device 99 stores input waveform data 126.

  After touching the start button 130, when the finger 44 touches the slider 128 and moves the finger 44 in the vertical direction of the screen, a wave is drawn on the left side of the slider 128. The waves are automatically displayed to move to the left side of the figure at a constant speed. When the pain is felt small, the slider 128 is moved to the direction indicated as “no pain”. When pain is felt greatly, the slider 128 is moved to the direction indicated as “pain”.

  As described above, the slider position detecting means 138 captures the temporal change of pain only by moving the finger 44 on the slider 128 in the vertical direction of the screen. The graph drawn by the constant velocity moving means 136 moves to the left at a constant velocity. The drawing means 140 redraws the input waveform each time. As a result, input waveform data 126 as shown in the following drawing can be acquired.

FIG. 16 is an explanatory diagram of the input waveform data 126 acquired in the fourth embodiment.
The vertical axis in the figure indicates the degree of pain. The horizontal axis shows the passage of time. The input waveform data 126 that has been input indicates the time variation of the magnitude of pain as it is. In the case of this embodiment, since a pain-free line can be provided, a pain change graph can be obtained as it is. The vibration waveform 88 for driving the vibrator can be obtained in the same manner as in the previous embodiments.

FIG. 17 is a flowchart illustrating the processing operation of the apparatus according to the second embodiment.
First, as shown in FIG. 12, the subject draws a waveform with a finger on the display of the tablet 40 in step S11. In step S12, it is determined whether or not the test is started. If the test button 95 is tapped, the result of this determination is yes. In that case, the process proceeds to step S13. If no, the process waits until the test button 95 is tapped in step S12.

  In step S13, the data reading unit 100 acquires a waveform drawn on the display. As a result, the input waveform data 86 is stored in the storage device 99. In step S14, the digitizing means 102 digitizes the waveform. As a result, the digitized data 87 is stored in the storage device 99. In step S15, the envelope acquisition unit 104 acquires the envelope of the input waveform data 86. As a result, envelope data 89 is stored in the storage device 99.

  In step S16, the vibration pattern generation means 106 generates a vibration pattern. In step S17, the vibrator driving means 108 drives the vibrator. The subject compares this vibration pattern with his / her pain. If it is determined that they match, the determination button 96 is tapped. If it is determined that they do not match, the waveform is redrawn and the test button 95 is tapped again.

  In step S18, it is determined whether or not the enter button 96 has been tapped. If the result of this determination is yes, the process proceeds to step S19, and if no, the process returns to step S11. In step S19, the waveform is determined. That is, as described with reference to FIG. 13E, the single waveform detection means 110 compares the waveform 90 of one unit with the basic waveform to determine the nature of the pain. Next, in step S20, the periodicity already described is determined. In step S21, these determination results are output to the display.

FIG. 18 is a flowchart illustrating the processing operation of the apparatus according to the third embodiment.
As shown in FIG. 14, in step S31, an image of the pain tool is displayed. Then, let the subject touch his finger. In step S32, when a fingertip touches a predetermined area of the window, this is detected and processing starts. In step S33, the contact pressure detection means calculates the contact area of the finger.

  The output of the contact pressure detection means 114 is processed in the same manner as in the embodiment of FIG. That is, it is digitized by the digitizing means 102 shown in FIG. 12, and envelope data is generated by the envelope obtaining means 104 in step S34. In step S35, a vibration waveform is generated. In step S36, the vibrator is driven. While touching a finger, it is preferable to operate so as to vibrate in response to the pressure of the finger.

  In step S37, it is determined whether the time is up. The detection of the contact pressure may be performed with a time limit of about 1 minute, for example. It may be stopped when the finger is removed from the display. When the time is up, the process proceeds to step S38. In step S38, input waveform data is generated, and in step S39, the waveform is determined. Subsequently, periodicity is determined in step S40. In step S41, the result is output. These processes are the same as those already described in the previous embodiment.

FIG. 19 is a flowchart of processing operations of the apparatus according to the fourth embodiment.
This process starts by detecting the tap of the start button 130 in step S51. In step S52, the graph constant velocity moving unit 136 starts moving the graph. In this state, when the slider 128 is moved with the finger 44, the input waveform data 126 as shown in FIG. 15 is displayed on the display. In step S53, the slider position detecting means 138 detects the state of the slider. In step S54, the drawing unit 140 draws a graph corresponding to the state of the slider.

  The data reading unit 100 shown in FIG. 12 acquires input waveform data 126 that can be digitized from the drawn graph. The subsequent processing is exactly the same as in the embodiment of FIG. When a touch on the test button 95 is detected in step S56, the vibrator is driven in step S57. If a touch on the enter button 96 is detected in step S58, the process proceeds to step S59. In step S59, the waveform is determined, and in step S60, the periodicity is determined. In step S61, the result is output.

20 to 22 are explanatory diagrams for explaining the results of the pain evaluation using vibration.
FIG. 20 shows a list of evaluation results of three subjects. The test subject asked five experiences that had been painful in the past, and confirmed whether the pain could be expressed using the vibration function of the smartphone. In addition, I asked the pain to be expressed with a “jagged” line, and investigated what kind of features appeared. The “jagged” line is that of Example 2 shown in FIG.

  The subjects exemplified here are one male 24 years old and two females 20 years old. For example, the abdominal pain of a 24-year-old man was represented by a “jagged” line with the symbol C-01 in FIG. Mr. C expressed the pain with lines C-01 to C-05, Mr. D with the lines D-01 to D-05, and Mr. E with the lines E-01 to E-05.

  The features seen in these “jagged” lines are as follows. For example, Mr. D did not start the wave from the bottom and the amplitude did not exceed the starting line for “pneumothorax” pain. It is thought that these expressed the breathlessness of pneumothorax. As for “when you fall asleep,” it is thought that the maximum pain was felt momentarily when the neck was turned to the angle where the pain was felt, the amplitude showed the maximum value, and the pain of pulling the tail was expressed by a fine wave. . It is thought that the beginning of the wave has turned upward because of the pain of stinging.

  In the case of Mr. E, in the case of “the ball hits the face”, it is considered that the pain as a gene that draws a tail after a large pain is expressed with a fine amplitude. As for “abdominal pain”, it was found that the wavelength range was longer than other jagged objects, and the patient felt dull pain. From this, it is considered that the greater the angle of the jagged wave, the more dull pain is expressed. As for “caval pain”, it is thought that it feels throbbing pain that matches the pulse with a large amplitude and expresses persistent pain with fine waves.

  Then, each smartphone was given a vibration corresponding to the “jagged” line to evaluate its effectiveness. In other words, in response to the question “Do you think you can express the intensity of pain using vibration?”, The evaluation was given in five stages from 5 (can) to 1 (cannot). In the case of evaluation 5 or 4, the opinion that it can be expressed, in the case of evaluation 3, the opinion that it is not different from that of Example 1, and in the case of evaluation 1 or 2, the effect is not felt so much Become. FIG. 21 shows the evaluation results as a line graph.

  From the above experimental results, the expression of pain using vibration was able to express pain more accurately by the presence of tactile feedback, the change of pain sensation, pain, It was found that there was an effect such as being able to remember more specifically.

  For example, Mr. C (male) uses 5 to 4 for expressing pain using vibration. In addition, Mr. D (female) assigns three types of pain to 5-4 on a five-point scale. For example, Mr. C (male) evaluates 5 for abdominal pain, 5 for low back pain after walking for 15 hours, 4 for headache, 4 for pain falling from the stairs, and 3 for pain when the thumb is cut. . These evaluations are evaluations obtained from the actual feelings of the subjects, and prove that pain can be expressed by vibration.

  Further, when paying attention to the jagged shape (characteristic of the waveform), it can be seen that the magnitude of the amplitude expresses the intensity of the pain, and expresses whether the pain is stinging or dull depending on the angle of the wavelength. Also, it can be seen that the overall length indicates the continuity of the pain, and if the jagged shape of the similar shape is repeatedly drawn, it indicates the repeatability of the pain. Some of these features can be automatically determined as in the above embodiment. Other characteristics may be determined by analysis by an expert. Therefore, it became clear that various pain information can be easily estimated from the primitive shape of the waveform. It is also possible to determine the evaluation standard by determining the maximum value of the amplitude when drawing the jaggedness, and to estimate the degree of pain intensity more accurately.
