<1-1. Overall system configuration>
FIG. 1 is a diagram schematically showing a biofeedback system 10 according to the present embodiment. Biofeedback refers to an operation of measuring a physiological activity (reaction) indicating the state of a living body, converting the activity into easy-to-understand information (for example, image, voice, or vibration) and transmitting the activity to the living body. The biofeedback system 10 is used, for example, for functional recovery (rehabilitation) of the user's body. Rehabilitation is an example of "predetermined exercise" in the present invention. The biofeedback system 10 is used, for example, for rehabilitation of a user who cannot move the spinal column, knees, hips or shoulders as desired. As used herein, the term "user" refers to a person undergoing rehabilitation through the biofeedback system 10. The biofeedback system 10 may be operated by an operator other than the user. Examples of "operators" include physiotherapists, nurses and doctors.

As shown in FIG. 1, the biofeedback system 10 includes an information terminal 100 and an orthotic device 200. The orthotic device 200 is worn by the user and is configured to detect parameters related to the user's posture. In the example shown in FIG. 1, the orthotic device 200 is configured to detect the degree of bending (angle) of the user's back.

Ultimately, users need to be able to move their bodies as they wish without referring to posture information. In the biofeedback system 10 according to the present embodiment, a device is provided so that the user can move his / her body as he / she wants without referring to the posture information.

That is, in the biofeedback system 10, the information terminal 100 continuously notifies the user of the posture information, while stopping the notification of the posture information at a predetermined timing. Therefore, according to the biofeedback system 10, rehabilitation in a state where posture information is notified (hereinafter, also referred to as “first rehabilitation”) to rehabilitation in a state where posture information is not notified (hereinafter, also referred to as “second rehabilitation”). .) Can be switched at an appropriate timing. As a result, according to the biofeedback system 10, it is possible to effectively support rehabilitation so that the user can move his / her body as he / she wants without referring to the posture information. The first rehabilitation is an example of the first predetermined exercise, and the second rehabilitation is an example of the second predetermined exercise.

The capacitance sensor 21 is composed of an electrode layer 241,242 and an insulating layer 246 sandwiched between the electrode layers 241,242. The capacitance sensor 22 is composed of an electrode layer 243 and 244 and an insulating layer 247 sandwiched between the electrode layers 243 and 244.

Each electrode layer is formed of, for example, a thin film formed of metal or a conductive resin, or a fabric knitted or woven using metallic fibers or conductive fibers. Further, each insulating layer is formed of, for example, a resin film such as a polyurethane film, a PET (polyethylene terephthalate) film, and a biaxially stretched polypropylene film. Two layers adjacent to each other are joined, for example, by an adhesive.

FIG. 5 is a diagram schematically showing a curved state of the fiber sensor 240. As shown in FIG. 5, in this example, the electrode layer 241 of the fiber sensor 240 is curved in a convex shape, and the electrode layer 244 of the fiber sensor 240 is curved in a concave shape. In this case, the insulating layer 246 included in the capacitance sensor 21 becomes thin, and the insulating layer 247 included in the capacitance sensor 22 becomes thick. As a result, the capacitance C1 of the capacitance sensor 21 becomes large, and the capacitance C2 of the capacitance sensor 22 becomes small. In the orthotic device 200, the bending degree (angle) of the fiber sensor 240 can be calculated from the difference between the capacitance C1 and the capacitance C2.

The storage unit 220 is an auxiliary storage device such as a hard disk drive or a solid state drive. The storage unit 220 is configured to store, for example, the control program 221. By executing the control program 221 by the CPU 211, various functions in the orthotic device 200 are realized.

[2. motion]
<2-1. Calibration operation>
In the biofeedback system 10, first, the orthotic device 200 is calibrated. Calibration is a task of determining a reference (position at zero angle) for the degree of bending of the fiber sensor 240. Calibration is performed with the orthotic device 200 worn by the user.

FIG. 6 is a flowchart showing the procedure of the calibration operation. The process shown in this flowchart is executed by the control unit 210 with the orthotic device 200 worn by the user at the time of preparing for the start of rehabilitation.

With reference to FIG. 6, the control unit 210 determines whether or not an instruction to execute calibration (hereinafter, also referred to as “calibration execution instruction”) has been received from an operator such as a physiotherapist (hereinafter, also referred to as “calibration execution instruction”). Step S100). For example, the operator gives a calibration execution instruction at the timing when the posture of the user becomes the ideal posture.

If it is determined that the calibration execution instruction is not accepted (NO in step S100), the control unit 210 waits until the calibration execution instruction is accepted. On the other hand, when it is determined that the calibration execution instruction has been accepted (YES in step S100), the control unit 210 executes the calibration (step S110). Specifically, the control unit 210 considers the angle (bending degree) of the fiber sensor 240 at the timing of receiving the calibration execution instruction to be zero. The control unit 210 outputs the amount of change from the angle regarded as zero as the angle of the fiber sensor 240. According to the biofeedback system 10, for example, by using the ideal state of a specific site (for example, the spinal column) as a reference, the amount of deviation from the ideal state can be detected as an angle.

<2-2. Behavior during rehabilitation>
When the rehabilitation is started, each of the device 200 and the information terminal 100 performs various operations. As described above, for example, in the information terminal 100, a switching operation between the first rehabilitation and the second rehabilitation is performed. The types of switching modes include a first automatic mode, a second automatic mode, and a manual mode. The trigger for switching the rehabilitation type changes depending on which mode is set. Hereinafter, the operation of the equipment 200, the operation of the information terminal 100 in the first automatic mode, the operation of the information terminal 100 in the second automatic mode, the operation of the information terminal 100 in the manual mode, the common operation of the information terminal 100 in each mode, and The operation of the information terminal 100 other than the time of rehabilitation will be described in order.

(2-2-1. Operation of the device)
FIG. 7 is a flowchart showing the operation procedure of the orthotic device 200 during rehabilitation. The process shown in this flowchart is repeatedly executed by the control unit 210 in a predetermined cycle.

With reference to FIG. 7, the control unit 210 acquires the calculation result from the capacitance difference calculation unit 250 (step S200). The control unit 210 calculates the angle of the fiber sensor 240 based on the calculated capacitance difference (step S210). The control unit 210 controls the communication I / F 230 so as to transmit the calculated information (angle information) indicating the angle to the information terminal 100 (step S220). By repeating this process in a predetermined cycle, the latest angle information of the fiber sensor 240 is transmitted to the information terminal 100 in a predetermined cycle.

(2-2-2. Operation of information terminal in the first automatic mode)
FIG. 8 is a flowchart showing an operation procedure of the information terminal 100 during the first rehabilitation when the information terminal 100 is set to the first automatic mode. The process shown in this flowchart is executed by the control unit 110 during the first rehabilitation when the information terminal 100 is set to the first automatic mode.

With reference to FIG. 8, the control unit 110 determines whether or not the angle information has been acquired from the orthotic device 200 via the communication I / F 130 (step S300). If it is determined that the angle information has not been acquired (NO in step S300), the control unit 110 waits until the angle information is acquired.

On the other hand, when it is determined that the angle information has been acquired (YES in step S300), the control unit 110 stores the acquired angle information in the storage unit 120 (step S310). The control unit 110 generates posture information based on the acquired angle information (step S320). The posture information is image information indicating the state of the posture of the user. The control unit 110 controls the monitor 140 so as to display the generated posture information (step S330).

FIG. 9 is a diagram schematically showing an example of posture information displayed on the monitor 140. With reference to FIG. 9, the scale image 300 is displayed on the monitor 140. The scale image 300 has, for example, a rectangular shape, and angles (angles of the fiber sensor 240) are assigned at equal intervals in the longitudinal direction. In this example, angles of −30 ° to 60 ° are assigned at equal intervals.

A bar image 305 is displayed on the scale image 300. The bar image 305 has a rectangular shape, and one end of the bar image 305 is fixed at a position of 0 °. The position of the other end of the bar image 305 is variable. The position of the other end of the bar image 305 indicates the angle of the current fiber sensor 240. That is, as the angle of the fiber sensor 240 changes, the bar image 305 expands and contracts in the longitudinal direction of the scale image 300. By visually recognizing the posture information, the user can recognize how the spinal column is bent.

Further, the upper limit line image 310 shows the position of the upper limit value of the angle range targeted by the user, and the lower limit line image 315 shows the position of the lower limit value of the angle range targeted by the user. By visually recognizing the bar image 305, the upper limit line image 310, and the lower limit line image 315, the user can recognize whether or not the current bending condition of the spinal column is within the target range.

When the posture information is displayed in step S330 with reference to FIG. 8 again, the control unit 110 determines whether or not the first rehabilitation time has elapsed from the start time of the first rehabilitation (step S340). The first rehabilitation time indicates the time during which the first rehabilitation is continuously performed, and is determined in advance in, for example, the control program 121.

If it is determined that the first rehabilitation time has not elapsed (NO in step S340), the control unit 110 repeats the processes of steps S300 to S340 until the first rehabilitation time elapses. On the other hand, when it is determined that the first rehabilitation time has elapsed (YES in step S340), the control unit 110 controls the monitor 140 so as to stop displaying the posture information, and shifts to the second rehabilitation process (YES in step S340). Step S350). According to the biofeedback system 10, the type of rehabilitation can be switched from the first rehabilitation to the second rehabilitation at an appropriate timing programmed in advance.

FIG. 10 is a flowchart showing an operation procedure of the information terminal 100 during the second rehabilitation when the information terminal 100 is set to the first automatic mode. The process shown in this flowchart is executed by the control unit 110 during the second rehabilitation when the information terminal 100 is set to the first automatic mode.

With reference to FIG. 10, the control unit 110 determines whether or not the angle information has been acquired from the orthotic device 200 via the communication I / F 130 (step S400). If it is determined that the angle information has not been acquired (NO in step S400), the control unit 110 waits until the angle information is acquired.

On the other hand, when it is determined that the angle information has been acquired (YES in step S400), the control unit 110 stores the acquired angle information in the storage unit 120 (step S410). The control unit 110 determines whether or not the second rehabilitation time has elapsed from the start time of the second rehabilitation (step S420). The second rehabilitation time indicates the time for continuously performing the second rehabilitation, and is determined in advance in the control program 121, for example.

If it is determined that the second rehabilitation time has not elapsed (NO in step S420), the control unit 110 repeats the processes of steps S400 to S420 until the second rehabilitation time elapses. On the other hand, when it is determined that the second rehabilitation time has elapsed (YES in step S420), the control unit 110 executes the process according to the control program 121 (step S430). The control unit 110 executes, for example, a process for shifting to the first rehabilitation again.

By the way, if the type of rehabilitation is suddenly switched, it may surprise the user. In order to avoid such a situation, in the biofeedback system 10, a notice is given to notify the user that the type of rehabilitation will be changed after a few seconds.

FIG. 11 is a flowchart showing the procedure of the transition notice of the rehabilitation type. The process shown in this flowchart is, for example, executed by the control unit 110 in parallel with the process shown in the flowchart of FIG. 8 or FIG.

With reference to FIG. 11, the control unit 110 determines whether or not the transition notice timing of the rehabilitation type has arrived (step S500). The transition advance notice timing is, for example, a timing several seconds before the lapse of the first rehabilitation time in step S340 of FIG. 8, or a timing several seconds before the lapse of the second rehabilitation time in step S420 of FIG.

When it is determined that the shift notice timing has not arrived (NO in step S500), the control unit 110 waits until the shift notice timing arrives. On the other hand, when it is determined that the transition notice timing has arrived (YES in step S500), the control unit 110 controls the monitor 140 to execute the shift notice (step S510). For example, the control unit 110 causes the monitor 140 to display the countdown. According to the biofeedback system 10, for example, since the transition to the second rehabilitation is announced, the user can face the second rehabilitation after preparing his / her mind in advance.

(2-2-3. Operation of information terminal in the second automatic mode)
FIG. 12 is a flowchart showing an operation procedure of the information terminal 100 during the first rehabilitation when the information terminal 100 is set to the second automatic mode. The process shown in this flowchart is executed by the control unit 110 during the first rehabilitation when the information terminal 100 is set to the second automatic mode.

With reference to FIG. 12, the control unit 110 determines whether or not the angle information has been acquired from the orthotic device 200 via the communication I / F 130 (step S600). If it is determined that the angle information has not been acquired (NO in step S600), the control unit 110 waits until the angle information is acquired.

On the other hand, when it is determined that the angle information has been acquired (YES in step S600), the control unit 110 stores the acquired angle information in the storage unit 120 (step S610). The control unit 110 generates posture information based on the acquired angle information (step S620). The posture information is image information indicating the state of the posture of the user. The control unit 110 controls the monitor 140 so as to display the generated posture information (step S630). The posture information is, for example, image information as shown in FIG.

The control unit 110 determines whether or not the angle information (parameter) acquired in step S600 satisfies the first predetermined condition (step S640). As an example of the first predetermined condition, (1) the angle is continuously within the range of the first threshold value for a predetermined time, and (2) the angle is continuously maintained for a predetermined time and is within the range of the second threshold value (second threshold value). > It is within the range of the first threshold value), and the frequency of the fluctuation of the angle is lower than the predetermined threshold value.

When it is determined that the angle information does not satisfy the first predetermined condition (NO in step S640), the control unit 110 repeats the processes of steps S600 to S640 until the angle information satisfies the first predetermined condition. On the other hand, when it is determined that the angle information satisfies the first predetermined condition (YES in step S640), the control unit 110 controls the monitor 140 so as to stop the display of the posture information, and shifts to the second rehabilitation process. (Step S650). According to the biofeedback system 10, the type of rehabilitation can be switched from the first rehabilitation to the second rehabilitation at an appropriate timing when the parameter (angle information) satisfies a predetermined condition.

FIG. 13 is a flowchart showing an operation procedure of the information terminal 100 during the second rehabilitation when the information terminal 100 is set to the second automatic mode. The process shown in this flowchart is executed by the control unit 110 during the second rehabilitation when the information terminal 100 is set to the second automatic mode.

With reference to FIG. 13, the control unit 110 determines whether or not the angle information has been acquired from the orthotic device 200 via the communication I / F 130 (step S700). If it is determined that the angle information has not been acquired (NO in step S700), the control unit 110 waits until the angle information is acquired.

On the other hand, when it is determined that the angle information has been acquired (YES in step S700), the control unit 110 stores the acquired angle information in the storage unit 120 (step S710). The control unit 110 determines whether or not the angle information (parameter) satisfies the second predetermined condition (step S720). As an example of the second predetermined condition, (1) the angle continues for a predetermined time and is out of the range of the third threshold value, and (2) the angle continues for a predetermined time and the fourth threshold value (fourth threshold value < It is out of the range of the third threshold value), and the frequency of the fluctuation of the angle is higher than the predetermined threshold value.

When it is determined that the angle information does not satisfy the second predetermined condition (NO in step S720), the control unit 110 repeats the processes of steps S700 to S720 until the angle information satisfies the second predetermined condition. On the other hand, when it is determined that the angle information satisfies the second predetermined condition (YES in step S720), the control unit 110 executes the process according to the control program 121 (step S730). The control unit 110 executes, for example, a process for shifting to the first rehabilitation again.

In the second automatic mode, it can be said that the rehabilitation progresses smoothly as the ratio of the second rehabilitation time to the total rehabilitation time increases. For example, after the end of rehabilitation, the ratio of the time of the first or second rehabilitation to the total time of the rehabilitation may be calculated, and the calculated ratio may be displayed on the monitor 140. This allows the user to visually recognize how effective the rehabilitation is. Further, for example, after the end of rehabilitation, the transition from the past of the ratio of the time of the first or second rehabilitation to the total time of the rehabilitation may be displayed on the monitor 140. As a result, the user can visually recognize how the effect of the rehabilitation is manifested by continuing the rehabilitation.

(2-2-4. Operation of information terminal in manual mode)
FIG. 14 is a flowchart showing an operation procedure of the information terminal 100 during the first rehabilitation when the information terminal 100 is set to the manual mode. The process shown in this flowchart is executed by the control unit 110 during the first rehabilitation when the information terminal 100 is set to the manual mode.

With reference to FIG. 14, the control unit 110 determines whether or not the angle information has been acquired from the orthotic device 200 via the communication I / F 130 (step S800). If it is determined that the angle information has not been acquired (NO in step S800), the control unit 110 waits until the angle information is acquired.

On the other hand, when it is determined that the angle information has been acquired (YES in step S800), the control unit 110 stores the acquired angle information in the storage unit 120 (step S810). The control unit 110 generates posture information based on the acquired angle information (step S820). The posture information is image information indicating the state of the posture of the user. The control unit 110 controls the monitor 140 so as to display the generated posture information (step S830). The posture information is, for example, image information as shown in FIG.

The control unit 110 determines whether or not the instruction to stop displaying the posture information has been received (step S840). For example, the control unit 110 determines whether or not the posture information display stop instruction has been received from the operator via the reception unit 150.

If it is determined that the display stop instruction is not accepted (NO in step S840), the control unit 110 repeats the processes of steps S800 to S840 until the display stop instruction is received. On the other hand, when it is determined that the display stop instruction has been accepted (YES in step S840), the control unit 110 controls the monitor 140 so as to stop the display of the posture information, and shifts to the second rehabilitation process (step S850). ). According to the biofeedback system 10, the type of rehabilitation can be switched from the first rehabilitation to the second rehabilitation at a timing considered appropriate by the operator.

FIG. 15 is a flowchart showing an operation procedure of the information terminal 100 during the second rehabilitation when the information terminal 100 is set to the manual mode. The process shown in this flowchart is executed by the control unit 110 during the second rehabilitation when the information terminal 100 is set to the manual mode.

With reference to FIG. 15, the control unit 110 determines whether or not the angle information has been acquired from the orthotic device 200 via the communication I / F 130 (step S900). If it is determined that the angle information has not been acquired (NO in step S900), the control unit 110 waits until the angle information is acquired.

On the other hand, when it is determined that the angle information has been acquired (YES in step S900), the control unit 110 stores the acquired angle information in the storage unit 120 (step S910). The control unit 110 determines whether or not the instruction to restart the display of the posture information has been received (step S920).

If it is determined that the display restart instruction is not accepted (NO in step S920), the control unit 110 repeats the processes of steps S900 to S920 until the display restart instruction is received. On the other hand, when it is determined that the display restart instruction has been accepted (YES in step S920), the control unit 110 executes the process according to the control program 121 (step S930). The control unit 110 executes, for example, a process for shifting to the first rehabilitation again.

(2-2-5. Common operation of information terminals in each mode)
FIG. 16 is a flowchart showing a procedure of an operation executed in the information terminal 100 regardless of the mode. The process shown in this flowchart is repeatedly executed by the control unit 110 during the second rehabilitation. The process shown in this flowchart is not executed during the first rehabilitation.

With reference to FIG. 16, the control unit 110 determines whether or not the angle information has been acquired from the orthotic device 200 via the communication I / F 130 (step S1000). If it is determined that the angle information has not been acquired (NO in step S1000), the control unit 110 waits until the angle information is acquired.

On the other hand, when it is determined that the angle information has been acquired (YES in step S1000), the control unit 110 determines whether or not the acquired angle information (parameter) is out of the target range (step S1010). The target range is defined by, for example, an upper limit value and a lower limit value of an angle, or an upper limit value of an angle fluctuation. Information indicating the target range is stored in the storage unit 120.

When it is determined that the parameter is within the target range (NO in step S1010), the control unit 110 executes the process of step S1000 again. On the other hand, when it is determined that the parameter is out of the target range (YES in step S1010), the control unit 110 determines whether or not the state in which the parameter is out of the target range continues for a predetermined time (step S1020). ..

If it is determined that the time has not continued for a predetermined time (NO in step S1020), the control unit 110 executes the process of step S1000 again. On the other hand, if it is determined that the continuation has continued for a predetermined time (YES in step S1020), the control unit 110 controls the monitor 140 to display an alert (step S1030).

FIG. 17 is a diagram schematically showing an example of an alert displayed on the monitor 140. As shown in FIG. 17, the message 400 is displayed on the monitor 140. The message 400 is a message for notifying the user that the posture has deteriorated.

According to the biofeedback system 10, when the posture of the user is deteriorated, a predetermined notification (display of an alert) is given, so that the user can be urged to improve the posture. Further, according to the biofeedback system 10, since the predetermined notification (alert display) is not performed during the first rehabilitation, it is possible to avoid the situation where excessive information is provided to the user.

<2-3. Operation other than during rehabilitation>
FIG. 18 is a flowchart showing the procedure of the operation performed after the rehabilitation. The process shown in this flowchart is repeatedly executed by the control unit 110 after the rehabilitation is completed.

With reference to FIG. 18, the control unit 110 determines whether or not the display instruction of the transition of the posture information (first posture information) during the second rehabilitation has been received (step S1100). When it is determined that the display instruction has been accepted (YES in step S1100), the control unit 110 generates the first posture information based on the angle information stored in the storage unit 120, and displays the first posture information. Controls the monitor 140 (step S1110). The first posture information is, for example, image information.

FIG. 19 is a diagram showing an example of the first posture information. With reference to FIG. 19, the horizontal axis represents time and the vertical axis represents the angle of the fiber sensor 240. The first posture information shows the transition of the angle information during the second rehabilitation. According to the biofeedback system 10, since the first posture information is notified after the rehabilitation, the user can confirm his / her posture during the second rehabilitation after the rehabilitation.

With reference to FIG. 18 again, when it is determined in step S1100 that the display instruction is not accepted (NO in step S1100), the control unit 110 gives an instruction to display the first and second posture information in a comparable manner. It is determined whether or not it has been accepted (step S1120). When it is determined that the instruction for displaying the first and second posture information in a comparable manner is not accepted (NO in step S1120), the control unit 110 executes the process of step S1100 again.

On the other hand, when it is determined that the instruction to display the first and second posture information in a comparable manner has been received (YES in step S1120), the control unit 110 causes the first and second posture information to be displayed in a comparable manner. The monitor 140 is controlled (step S1130). The second posture information shows the transition of the angle information during the first rehabilitation. In step S1130, for example, the first posture information and the second posture information are displayed on the monitor 140 in a state of being arranged side by side.

According to the biofeedback system 10, the first posture information and the second posture information are displayed side by side, so that the user can visually see his / her posture during the first rehabilitation and his / her posture during the second rehabilitation. Can be easily compared.

[3. feature]
As described above, in the biofeedback system 10 according to the present embodiment, the posture information is continuously notified to the user, while the notification of the posture information is stopped at a predetermined timing. Therefore, according to this biofeedback system, it is possible to switch from the first rehabilitation to the second rehabilitation at an appropriate timing. As a result, according to the biofeedback system 10, it is possible to effectively support the rehabilitation of the user.

The biofeedback system 10 is an example of the "biofeedback system" of the present invention. The communication I / F 130 is an example of the "acquisition unit" of the present invention, and the monitor 140 is an example of the "notification unit" of the present invention. The reception unit 150 is an example of the "reception unit" of the present invention. The storage unit 120 is an example of the "storage unit" of the present invention. The fiber sensor 240 is an example of the "sensor" of the present invention. Further, it can be said that the configuration including the capacitance difference calculation unit 250 and the control unit 210 functions as an angle detection circuit.

[4. Modification example]
Although the embodiments have been described above, the present invention is not limited to the above embodiments, and various modifications can be made without departing from the spirit of the present invention. Hereinafter, a modified example will be described.

<4-1>
In the above embodiment, the fiber sensor 240 is used as a sensor for detecting the angle of a specific part of the user's body. However, the sensor that detects the angle of a specific part of the user's body is not limited to the fiber sensor 240. Any sensor may be used as long as the angle of a specific part of the user's body can be detected. That is, various known angle sensors can be used. For example, the angle sensor may be realized by a magnetic sensor composed of a combination of a magnet and a Hall element, or may be realized by an encoder capable of detecting an angle.

<4-2>
Further, in the above embodiment, an example of feeding back the bending condition of the spinal column to the user has been mainly described, but the content of feeding back to the user is not limited to this. For example, the degree of bending of the knees, shoulders or hips, or the posture during walking may be fed back to the user. In this case, the user wears, for example, an orthotic device capable of detecting the bending of the knee, shoulder or hip, or the posture during walking.

<4-3>
Further, in the above embodiment, the angle of a specific part of the user's body is detected by the orthotic device 200. According to the biofeedback system 10, since the sensor is attached to the orthotic device 200 worn by the user, the information necessary for detecting the parameter (angle) can be acquired with higher accuracy, and as a result, the parameter is higher. It could be detected with high accuracy. However, the orthotic device 200 is not always essential. For example, the angle of a specific part of the user's body may be detected by the camera. Further, the angle may be detected in the information terminal 100 based on the image captured by the camera.

<4-4>
Further, in the above embodiment, the process shown in the flowchart of FIG. 16 was performed only during the second rehabilitation. However, the timing at which the process shown in the flowchart of FIG. 16 is executed is not limited to this. The process shown in the flowchart of FIG. 16 may be executed, for example, during the first rehabilitation.

<4-5>
Further, in the above embodiment, the information terminal 100 can be set to the first automatic mode, the second automatic mode, and the manual mode. However, the information terminal 100 does not necessarily have to be configurable in all modes. The information terminal 100 may be set to, for example, only some modes.

<4-6>
Further, in the above embodiment, the calculation of the angle information based on the output of the fiber sensor 240 was performed on the device 200. However, the calculation of the angle information does not necessarily have to be performed by the orthotic device 200. The output of the fiber sensor 240 may be transmitted to the information terminal 100, and the angle information may be calculated in the information terminal 100.

<4-7>
Further, in the above embodiment, the zero point correction of the angle information based on the calibration result is performed on the device 200. However, the zero point correction of the angle information does not necessarily have to be performed in the orthotic device 200. For example, the zero point correction of the angle information may be performed in the information terminal 100.

<4-8>
Further, in the above embodiment, an example of giving feedback to the user through an image has been mainly described, but the means for giving feedback to the user is not limited to this. For example, the feedback to the user may be given by outputting the sound from the speaker 160, or the feedback to the user may be given by vibrating the information terminal 100. Further, each of the feedback by voice output and the feedback by vibration may be performed by, for example, the device 200. That is, feedback may be provided by outputting sound from the orthotic device 200, or feedback may be provided by vibrating the orthotic device 200.

<4-9>
Further, in the above embodiment, as shown in FIG. 16, an alert display is performed when the state in which the angle information is out of the target range continues for a predetermined time. However, the method for notifying the user that the angle information is out of the target range is not limited to this. For example, the message may be displayed when the angle information is within the target range, and the message display may be stopped when the state where the angle information is outside the target range continues for a predetermined time.

FIG. 20 is a flowchart showing a procedure of an operation executed in the information terminal 100 regardless of the mode in the modified example. The process shown in this flowchart is repeatedly executed by the control unit 110 during the second rehabilitation. At the start of the process shown in this flowchart, a message is displayed on the monitor 140.

FIG. 21 is a diagram showing an example of a message displayed on the monitor 140 in the modified example. As shown in FIG. 21, the message 400A is displayed on the monitor 140. The message 400A is a message for notifying the user that there is no problem in the posture.

With reference to FIG. 20, the control unit 110 determines whether or not the angle information has been acquired from the orthotic device 200 via the communication I / F 130 (step S1200). If it is determined that the angle information has not been acquired (NO in step S1200), the control unit 110 waits until the angle information is acquired.

On the other hand, when it is determined that the angle information has been acquired (YES in step S1200), the control unit 110 determines whether or not the acquired angle information (parameter) is out of the target range (step S1210). When it is determined that the parameter is within the target range (NO in step S1210), the control unit 110 executes the process of step S1200 again. On the other hand, when it is determined that the parameter is out of the target range (YES in step S1210), the control unit 110 determines whether or not the state in which the parameter is out of the target range continues for a predetermined time (step S1220). ..

If it is determined that the time has not continued for a predetermined time (NO in step S1220), the control unit 110 executes the process of step S1200 again. On the other hand, if it is determined that the continuation has continued for a predetermined time (YES in step S1220), the control unit 110 controls the monitor 140 so as to stop displaying the message (step S1230). According to the biofeedback system 10, when the posture of the user is deteriorated, the predetermined notification (message display) is stopped, so that the user can be urged to improve the posture.

<4-10>
Further, in the above embodiment, the angle of a specific part of the user's body is detected by the fiber sensor 240. For example, another acceleration sensor may be held in the device 200. Thereby, the inclination of a specific part of the user's body may be detected. Further, the posture of the user may be detected only by the acceleration sensor. That is, the angle of a specific part of the user's body is not always detected, and only the inclination of the specific part of the user's body may be detected. In this case, the tilt of a specific part of the user's body may be continuously notified to the user, and the tilt notification may be stopped at a predetermined timing. Even with such a configuration, switching from the first predetermined movement to the second predetermined movement is performed at an appropriate timing. As a result, according to this biofeedback system, it is possible to effectively support a predetermined exercise of the user.

FIG. 22 is a diagram showing an example of a screen displayed on the monitor 140 when both the angle and the inclination of a specific part of the user's body are detected. As shown in FIG. 22, the image displayed on the monitor 140 includes an angle notification area 500 and a tilt notification area 510. The image displayed in the angle notification area 500 is, for example, the same as the example of FIG.

For example, spheres 512,514,516 are displayed in the tilt notification area 510. The sphere 512 moves, for example, according to the inclination of the user in the roll direction, and the sphere 514 moves, for example, according to the inclination of the user in the tilt direction. The sphere 516 makes a movement that combines the movements of the spheres 512 and 514. By visually recognizing the tilt notification area 510, the user can easily recognize the tilt state of his / her body.
