The pressure sensor 26 is arranged far above the pressure sensor 24 and the pressure sensor 25. The pressure sensor 26 is located corresponding to the shoulder of the seated person and can measure the pressure value from the shoulder of the seated person.

In the present embodiment, the seat system 1 shall provide a game of reflex measurement using each pressure sensor 21 to 26. In the present embodiment, each pressure sensor 21 to 26 is an example of a sensor that acquires a measured value for detecting the movement of a seated person sitting on the seat body S10. The game of reflexes measurement is a game in which a seated person sitting on the seat body S10 can measure reflexes according to a pose or a message of a character displayed on the display DSP of the smartphone SP.

The seat body S10 is provided with a holder 4 for holding the smartphone SP. The holder 4 is formed by bending a wire, one end of which is fixed to the seat back S2, and the other end of which is provided with a fixing portion 4A for fixing the smartphone SP. By fixing the smartphone SP to the fixing portion 4A, the seated person can see the display DSP of the smartphone SP without holding the smartphone SP in his / her hand. Therefore, the seated person can perform the movement instructed in the game of reflex measurement using the whole body while watching the display DSP.

The seat experience device 10 includes an ECU 100 and a smartphone SP as an example of a terminal.
A short-range communication device 3A that enables short-range wireless communication such as Bluetooth (registered trademark) or Wi-Fi (registered trademark) is connected to the ECU 100. Further, the ECU 100 is connected to the pressure sensors 21 to 26.

The ECU 100, the smartphone SP, and the server SV have a CPU (not shown), a ROM, a RAM, a rewritable non-volatile memory, and the like, and execute a program stored in advance. The smartphone SP further includes a display DSP. By operating according to the program, the smartphone SP causes the smartphone SP to execute each step for executing the game of reflex measurement.

Specifically, the smartphone SP has a function of acquiring measured values from the pressure sensors 21 to 26 via the short-range communication device 3A and the ECU 100, and executing a game of reflex nerve measurement based on the acquired measured values. ing. Further, the smartphone SP can communicate with the server SV via the Internet.

The smartphone SP has a function of outputting an instruction to perform a predetermined action to the seated person during the game of reflex measurement. Specifically, the smartphone SP outputs an instruction randomly selected from a plurality of instructions as an instruction to perform a predetermined operation.

In the present embodiment, the smartphone SP gives the seated person a first instruction to raise both knees shown in FIG. 5 and an action to raise the left knee shown in FIG. 6 as instructions to perform a predetermined action. The second instruction for prompting and the third instruction for prompting the action of raising the right knee shown in FIG. 7 are randomly selected and output using a random value. Here, in each of the screens shown in FIGS. 6 and 7, the character performing the action of raising the left knee or the right knee is displayed in a manner as if the seated person is reflected by a mirror so that the seated person can easily understand. ing. In addition to the image displayed on the display DSP, each instruction may be given by voice output from the speaker of the smartphone SP.

The smartphone SP has a function of determining whether or not the seated person has performed a predetermined operation based on the change of the measured value (pressure) acquired from the pressure sensor corresponding to the instruction after outputting the instruction. .. Specifically, the smartphone SP acquires the measured value from the pressure sensor 21L arranged under the buttocks of the seated person when the selected instruction is the first instruction.

When the selected instruction is the second instruction, the smartphone SP acquires the measured value from the pressure sensor 23L arranged under the left thigh of the seated person. When the selected instruction is the third instruction, the smartphone SP acquires the measured value from the pressure sensor 23R arranged under the right thigh of the seated person.

Here, when the seated person performs the action of raising both knees corresponding to the first instruction, the measured value as shown in FIG. 8A is acquired from the pressure sensor 21L. The smartphone SP calculates the differential value shown in FIG. 8B based on the measured value acquired from the pressure sensor 21L, and compares this differential value with the third threshold value TH3 and the threshold value TH11 to give the first instruction. The output timing is determined, and it is determined whether or not the seated person has performed a predetermined operation.

Specifically, the smartphone SP outputs an instruction (first instruction) to the seated person to perform a predetermined operation on condition that the differential value of the measured value acquired from the pressure sensor 21L is smaller than the third threshold value TH3. (Time t1). Here, in order to accurately measure the reflexes of the seated person, it is desirable that the seated person is in a stationary state before starting a predetermined movement. Therefore, the third threshold value TH3 is set to a value close to 0, and when the time based on the random value elapses after the differential value becomes smaller than the third threshold value TH3, an instruction randomly selected using the random value is given. By outputting, it is possible to accurately measure the reflexes of the seated person.

After outputting the instruction, the smartphone SP determines that the predetermined operation has started on the condition that the differential value exceeds the threshold value TH11 (time t2). The smartphone SP determines that the predetermined operation is completed on the condition that the differential value exceeds the threshold value TH11 and then becomes smaller than the threshold value TH11 (time t3).

Here, the threshold value TH11 corresponds to the first threshold value and the second threshold value. That is, in the present embodiment, the first threshold value and the second threshold value are set to the same value (threshold value TH1).

The smartphone SP has a function of calculating a response time T1 from outputting an instruction to perform a predetermined operation to performing a predetermined operation.

In the present embodiment, the response time T1 is the reaction time T11 from the output of the instruction to perform the predetermined operation to the start of the predetermined operation, and the predetermined operation after outputting the instruction to perform the predetermined operation. Includes the operation completion time T13 until the completion of. Further, in the present embodiment, the smartphone SP calculates the reaction time T11, the operation completion time T13, and the operation time T12 from the start to the completion of the predetermined operation.

When the seated person performs the operation of raising the left knee corresponding to the second instruction, the measured value as shown in FIG. 9A is acquired from the pressure sensor 23L. The smartphone SP calculates the differential value shown in FIG. 9B based on the measured value acquired from the pressure sensor 23L, and compares this differential value with the threshold values TH3 and TH12 to output the second instruction. Is determined, and it is determined whether or not the seated person has performed a predetermined operation.

The method of determining the timing of outputting the second instruction based on the third threshold value TH3 is the same as the method of determining the timing of outputting the first instruction described above.

The threshold TH12 corresponds to the first threshold and the second threshold. The threshold value TH12 is a threshold value corresponding to the differential value of the measured value acquired when the left knee raising operation is performed, and is different from the threshold value TH11 used when both knee raising operations are performed. .. In FIG. 9B, the threshold value TH12 is shown in the negative region for convenience, but the threshold value TH2 is assumed to be a positive value.

After outputting the instruction (time t11), the smartphone SP determines that the predetermined operation has started on the condition that the differential value is a negative value and the magnitude of the differential value exceeds the threshold value TH12. (Time t12). Further, the smartphone SP determines that the predetermined operation is completed on the condition that the magnitude of the differential value exceeds the threshold value TH12 and then the magnitude of the differential value becomes smaller than the threshold value TH12 (time t13).

The method of calculating the reaction time T11, the operation time T12, and the operation completion time T13 is the same as the case where the above-mentioned operation of raising both knees is performed.

When the seated person performs the action of raising the right knee corresponding to the third instruction, the measured value as shown in FIG. 10A is acquired from the pressure sensor 23R. The smartphone SP calculates the differential value shown in FIG. 10B based on the measured value acquired from the pressure sensor 23R, and compares this differential value with the threshold values TH3 and TH13 to output the third instruction. Is determined, and it is determined whether or not the seated person has performed a predetermined operation.

Here, the threshold value TH13 corresponds to the first threshold value and the second threshold value. In the present embodiment, the threshold value TH13 is set to the same value as the threshold value TH12 described above. A method of determining the timing (time t21) for outputting the third instruction, a method of determining the start of a predetermined operation (time t22), a method of determining the completion of the predetermined operation (time t23), and each time T11. The calculation method of ~ T13 is the same as the case of outputting the second instruction.

The smartphone SP outputs an instruction to perform a predetermined operation and calculates T11 to T13 at each time a plurality of times, notifies the seated person of the average of the acquired times T11 to T13, and at each time T11 to T13. It has a function of notifying the seated person of the value evaluated based on the average (hereinafter, also referred to as "evaluation value"). Further, the smartphone SP has a function of notifying the seated person of the best time of each of the acquired times T11 to T13 and notifying the seated person of the evaluation value determined based on the best time. More specifically, as shown in FIG. 11, the smartphone SP notifies the seated person by displaying the best time, the average value, and the evaluation value of T11 to T13 at each time on the display DSP.

The smartphone SP determines the evaluation value by comparing the calculated reaction time T11 with the stored reference reaction time T21. Specifically, the smartphone SP compares the calculated average value of the reaction time T11 with the reference reaction time T21 to determine an evaluation value with respect to the average value of the reaction time T11. Further, the smartphone SP compares the calculated best time of reaction time T11 with the reference reaction time T21 to determine an evaluation value for the best time of reaction time T11. The reference reaction time T21 to be compared with the average value and the reference reaction time T21 to be compared with the best time may be the same value or different values.

More specifically, the smartphone SP determines a higher evaluation value when the calculated reaction time T11 (average, best time) is shorter than the reference reaction time T21 (average, best time), and the longer the reaction time T21 (average, best time), the lower the evaluation value. To determine. In this embodiment, three stages of evaluation values such as a high evaluation value, a normal evaluation value, and a low evaluation value are illustrated. The evaluation values are "Excellent", "Good", and "Bad" in descending order.

The smartphone SP selects the evaluation value of "Excellent" when T11-T21 <-α1 and selects the evaluation value of "Good" when -α1 ≤ T11-T21 ≤ α2, and T11-T21> In the case of α2, the evaluation value of “Bad” is selected. Here, α1 and α2 are positive values.

The smartphone SP determines the evaluation values for the operation time T12 and the operation completion time T13 by comparing with the reference operation time T22 and the reference operation completion time T23, respectively, in the same manner as for the reaction time T11. You may.

The smartphone SP stores the attributes of the seated person, such as gender and age, and has a function of transmitting the calculated attributes of the seated person T11 to T13 and the attributes of the seated person to the server SV. The server SV has a function of accumulating the attributes of the seated person and T11 to T13 at each time.

Next, the operation of the smartphone SP (specifically, the processing unit in the smartphone SP) will be described in detail.
When the seated person launches the application for playing the reflex nerve measurement game, the smartphone SP starts the process shown in FIG. 2 (START). In this process, the smartphone SP first determines whether or not it is in a state where it can communicate with the sheet S (S11).

If it is determined in step S11 that communication is not possible (No), the smartphone SP ends this process. If it is determined in step S11 that communication is possible (Yes), the smartphone SP displays the start screen (see FIG. 3) of the reflex nerve measurement game on the display DSP (S12).

In the start screen shown in FIG. 3, a start button B1 for starting the reflex nerve measurement game and an end button B2 for ending the reflex nerve measurement game are displayed.

After step S12, the smartphone SP determines whether or not the start button B1 is selected (S13). If it is determined in step S13 that the start button B1 is not selected (No), the smartphone SP determines whether or not the end button B2 is selected (S14).

If it is determined in step S14 that the end button B2 is not selected (No), the smartphone SP returns to the process of step S12. If it is determined in step S14 that the end button B2 is selected (Yes), the smartphone SP ends this process.

If it is determined in step S13 that the start button B1 is selected (Yes), the smartphone SP displays the initial screen shown in FIG. On the initial screen, the standard posture that the seated person should take first is displayed using a picture image and a message consisting of a seat and a character. Specifically, on the initial screen, the character sitting deep on the seat is displayed in color and prominently, and the message "Please sit deep on your back" is displayed. As a result, the seated person can take a standard posture such as sitting deeply on the seat.

In addition, on the initial screen, three types of pictorial images and three types of messages indicating what kind of movement the seated person should perform from the reference posture are displayed in an inconspicuous manner such as thin lines or gray. Has been done. Specifically, on the initial screen, the character performing the action of raising the left knee is displayed with the message "Raise the left knee".

Similarly, on the initial screen, a character and a message corresponding to the action of raising both knees and a character and a message corresponding to the action of raising the right knee are displayed. In addition, a message is displayed on the initial screen to encourage the seated person to prepare for the movement, such as "When the posture is stable, one of the postures will be displayed. Please concentrate on the screen."

The three images corresponding to each motion are displayed side by side below the image showing the reference posture. The image corresponding to the movement of raising both knees is arranged in the center of the three images. The image corresponding to the action of raising the left knee is arranged to the left of the image corresponding to the action of raising both knees. The image corresponding to the action of raising the right knee is arranged to the right of the image corresponding to the action of raising both knees.

Returning to FIG. 2, the smartphone SP randomly selects an instruction to perform a predetermined operation after displaying the initial screen in step S15 (S16). Specifically, the smartphone SP randomly gives one instruction from the first instruction for urging both knees to be raised, the second instruction for urging the left knee to be raised, and the third instruction for urging the right knee to be raised. select.

After step S16, the smartphone SP sets a threshold value according to the selected instruction as a threshold value for determining a predetermined operation (S17). Specifically, for example, when the first instruction is selected as the instruction to perform a predetermined operation, the smartphone SP sets the threshold value TH11 (see FIG. 8B) in step S16.

After step S17, the smartphone SP starts acquiring the measured value from the pressure sensor according to the selected instruction (S18). Specifically, for example, when the first instruction is selected as the instruction to perform a predetermined operation, the smartphone SP starts acquiring the measured value from the pressure sensor 21L corresponding to the buttocks in step S18. Note that step S18 corresponds to the acquisition step.

After step S18, the smartphone SP starts calculating the differential value of the acquired measured value (S19). After step S19, the smartphone SP determines whether or not the differential value is smaller than the third threshold value TH3 (S20).

When it is determined in step S20 that the differential value is smaller than the third threshold value TH3 (Yes), the smartphone SP determines that the seated person is stationary in the reference posture, and then the time based on the random number value is determined. After that, the selected instruction is output (S21). The above-mentioned steps S20 and S21 correspond to the instruction step.

Specifically, when the smartphone SP outputs an instruction in step S21, the smartphone SP displays a screen (FIGS. 5 to 7) corresponding to the instruction on the display DSP. As shown in FIG. 5, on the screen corresponding to the first instruction, the character and the message corresponding to the action of raising both knees are displayed more emphasized than the other images depending on the presence or absence of coloring and the thickness of the line. To. As shown in FIG. 6, on the screen corresponding to the second instruction, the character and the message corresponding to the action of raising the left knee are displayed more emphasized than the other images depending on the presence or absence of coloring and the thickness of the line. To. As shown in FIG. 7, on the screen corresponding to the third instruction, the character and the message corresponding to the action of raising the right knee are displayed more emphasized than other images depending on the presence or absence of coloring and the thickness of the line. To.

Returning to FIG. 2, the smartphone SP determines whether or not the seated person has started a predetermined operation by determining whether or not the differential value exceeds the first threshold value after step S21 (S22). .. Specifically, for example, when the selected instruction is the first instruction, the smartphone SP determines whether or not the differential value exceeds the threshold value TH11 corresponding to the first instruction.

When it is determined in step S22 that the differential value exceeds the first threshold value (Yes), the smartphone SP calculates the reaction time T11 from the output of the instruction to the start of the predetermined operation (S23). After step S23, the smartphone SP determines whether or not the predetermined operation by the seated person is completed by determining whether or not the differential value is smaller than the second threshold value (S24).

Specifically, for example, when the selected instruction is the first instruction, the smartphone SP determines whether or not the differential value is smaller than the threshold value TH11 corresponding to the first instruction. The above-mentioned steps S22 and S24 correspond to the determination step.

When it is determined in step S24 that the differential value becomes smaller than the second threshold value (Yes), the smartphone SP should perform the predetermined operation with the operation time T12 from the start to the completion of the predetermined operation. The operation completion time T13 from the output of the instruction to the completion of the predetermined operation is calculated (S25). Either of the operation time T12 and the operation completion time T13 may be calculated first. That is, the operation completion time T13 may be calculated by calculating the operation time T12 first and adding the operation time T12 to the reaction time T11, or the operation completion time T13 may be calculated first and from the operation completion time T13. The operating time T12 may be calculated by subtracting the reaction time T11.

After step S25, the smartphone SP determines whether or not an instruction to perform a predetermined operation has been output a predetermined number of times (S26). Here, the predetermined number of times may be set arbitrarily, but in the present embodiment, it is set to 6 times.

If it is determined in step S26 that the instruction has not been output a predetermined number of times (No), the smartphone SP returns to the process of step S15. When it is determined in step S26 that the instruction has been output a predetermined number of times (Yes), the smartphone SP has the best time / average value of each time T11 to T13 in the first instruction and each time T11 to T13 in the second instruction. The best time / average value and the best time / average value of each time T11 to T13 in the third instruction are displayed on the display DSP to notify the seated person (S27: see FIG. 11). Further, in step S27, the smartphone SP also displays the evaluation value in each instruction on the display DSP and notifies the seated person (see FIG. 11). Here, step S27 corresponds to the notification step.

After step S27, the smartphone SP transmits each time T11 to T13 corresponding to each calculated instruction to the server SV together with the attributes of the seated person, and ends this process.

Next, an example of a specific operation of the seat system 1 will be described in detail.
As shown in FIG. 1, when the seated person operates the smartphone SP to launch the reflex nerve measurement application in a state where each device (S, SP) constituting the seat system 1 can communicate, the process shown in FIG. In step S11: Yes → step S12, the processes are sequentially executed. As a result, the start screen shown in FIG. 3 is displayed on the display DSP.

When the seated person selects the start button B1, the processes of step S13: Yes → step S15 are sequentially executed. As a result, the initial screen shown in FIG. 4 is displayed on the display DSP. According to the initial screen, the seated person takes a standard posture of sitting deeply on the seat S with his / her back, and waits for instructions while maintaining this posture.

While the seated person is waiting for an instruction, the smartphone SP first randomly selects one instruction from the three instructions (S16). Here, it is assumed that the second instruction is selected as the first instruction.

The smartphone SP that has selected the second instruction sets the threshold value TH12 (see FIG. 9B) according to the second instruction by sequentially executing the processes of steps S17 to S19, and also sets the second instruction (left thigh). ) Is acquired from the pressure sensor 23L corresponding to), and the differential value of the measured value is calculated. When the smartphone SP executes step S20, when the seated person keeps the reference posture, the differential value becomes smaller than the third threshold value TH3 as shown in FIG. 9B (time t11). , The smartphone SP determines Yes in step S20 and outputs the selected second instruction (S21, time t11).

As a result, the display of the display DSP is switched from the initial screen to the screen of FIG. 6, and the seated person performs an operation of raising the left knee according to the screen of FIG. By performing such an operation, the measured value of the pressure sensor 23L corresponding to the left thigh changes as shown in FIG. 9A, and the differential value of the measured value is as shown in FIG. 9B. Change.

When the smartphone SP determines that the differential value is negative and the magnitude of the differential value exceeds the threshold value TH12 (S22: Yes), the smartphone SP calculates the reaction time T11 during the left knee raising operation (S23). After that, when the smartphone SP determines that the magnitude of the differential value is smaller than the threshold value TH12 (S24: Yes), it calculates the operation time T12 and the operation completion time T13 during the left knee raising operation (S25).

After that, in step S26, the smartphone SP determines that the instruction has not been output a predetermined number of times (6 times) (No), and returns to step S15. As a result, the display of the display DSP returns from the screen of FIG. 6 to the initial screen again. Therefore, the seated person takes the reference posture again according to the initial screen and waits for the next instruction.

After that, for example, when the instructions are sequentially selected in the order of the first command, the third command, the third command, the second command, and the first command, and the processes of steps S15 to S26 are repeated five times, the smartphone SP causes the smartphone SP. , Yes is determined in step S26, and the screen shown in FIG. 11 is displayed on the display DSP. As a result, the seated person can know the best time and the average value of T11 to T13 at each time during the left knee raising operation, both knee raising operations, and the right knee raising operation. In addition, the seated person can also know the evaluation value at each operation.

As described above, according to the seat system 1 of the present embodiment, the following effects can be obtained.
When the seated person seated on the seat S performs a predetermined operation according to the instruction from the smartphone SP, the smartphone SP outputs the instruction to perform the predetermined operation based on the measured value acquired from the pressure sensor. Notify the seated person of the response time T1 and the like. Therefore, the seated person seated on the seat S can grasp his / her reflexes.

Since both the reaction time T11 and the operation completion time T13 are included as the response time T1, the reflexes of the seated person can be appropriately measured.

Since the smartphone SP determines the evaluation value by comparing the calculated reaction time T11 with the stored reference reaction time T21, the seated person can adjust his / her reflex nerve ability based on the evaluation value. You can know how much it is.

Since the movement of the seated person is determined based on the pressure value acquired from the pressure sensor, specifically, the differential value, the movement of the seated person can be satisfactorily determined.

By outputting the instruction on the condition that the differential value becomes smaller than the third threshold value TH3, the instruction to perform a predetermined operation is given when the seated person is in a state of being almost stationary in the reference posture. , Reflexes can be measured accurately.

According to this, since it is possible to instruct the seated person to perform different movements randomly selected, the seated person can know the reflexes for each movement. In addition, the seated person can grasp the movements that he / she is good at and the movements that he / she is not good at.

Since the output of the instruction and the calculation of T11 to T13 at each time are performed a plurality of times and the average value of T11 to T13 at each time is notified to the seated person, the seated person can know the average reflex nerve.

Since the attributes and response times of the seated person (T11 to T13 for each time) are accumulated by the server SV, for example, the response time of another person having the same attributes as the seated person can be compared with the response time of the seated person. ..
