BACKGROUND ART Conventionally, there is known a device in which a pressure sensor or the like is mounted on a driver's seat to estimate a sitting posture of a seated person (Patent Document 1).

JP, 11-064131, A

However, since the conventional device only evaluates and presents the sitting posture of the driver, it cannot be effectively used. Therefore, the inventors of the present application are studying a seat experience system having a seat experience device that can be operated by the motion of a seated person in order to propose a new value of the seat. The seats from now on can be used not only as a seat but also as a place for activities.

However, if there is only one type of sensor for detecting the motion of the seated person to operate the seat experience device, a person who cannot perform a motion suitable for the sensor, for example, some people with physical disabilities use the seat. There is a problem that it is not possible to do activities.

Therefore, an object of the present invention is to enable various people to use the seats for activities.

The present invention that solves the above-mentioned problems is provided with a first seat body, a second seat body, and a first seat body, and a first measurement for detecting a motion of a seated person sitting on the first seat body. A first sensor that obtains a value and a second sensor that is provided on the second seat body and that obtains a second measurement value for detecting the motion of a seated person sitting on the second seat body A second sensor and a seat experience device capable of acquiring the first measurement value from the first sensor and capable of acquiring the second measurement value from the second sensor are provided.
The seat experience device is a motion detection unit that detects a motion of the seated person based on the acquired input signal, and can detect the motion of the seated person based on both the first measurement value and the second measurement value. It has a motion detector. The seat experience device is configured to be able to perform a specific motion based on the motion detection unit detecting the motion of the seated person.

With such a configuration, the seated person sitting on the first seat body can detect the motion by the first sensor and cause the seat experience device to perform a specific motion based on the detection. On the other hand, the seated person sitting on the second seat body can detect the motion by the second sensor and cause the seat experience device to perform a specific motion based on the detection. Therefore, even a person who can only perform an operation that can be detected by only one of the first sensor and the second sensor can perform the activity using the seat. As a result, various people can use the seats for activities. For example, even people who do not have the same behavior can share the same community through the seat and provide an enjoyable experience.

Further, the present invention for solving the above-mentioned problems includes a seat body, a first sensor provided in the seat body, which acquires a first measurement value for detecting a motion of a seated person sitting on the seat body, and a seat body. And a second sensor for detecting a motion of a seated person sitting on the seat body, which acquires a second measurement value of a type different from the first measurement value, and a first measurement value from the first sensor. A seat experience device that is capable of acquiring the second measurement value from the second sensor may be provided. That is, one sheet body may include the first sensor and the second sensor.

With such a configuration, the seated person sitting on the seat body can detect the motion by the first sensor, and can cause the seat experience device to perform a specific motion based on the detection, and the motion by the second sensor. It is also possible to cause the seat experience device to perform a specific operation based on the detection. Therefore, even a person who can only perform an operation that can be detected by only one of the first sensor and the second sensor can perform the activity using the seat. As a result, various people can use the seats for activities.

In the seat experience system described above, it is preferable that the seat experience device is configured to notify the seated person of the action.

According to such a configuration, the seated person can be operated and the seat experience system can be effectively used.

In the seat experience system described above, the second sensor may include an amplifier circuit that brings the amplitude of the second measurement value closer to the amplitude of the first measurement value.

In the seat experience system described above, the seat experience device includes a sensor determination unit that determines whether the sensor connected to obtain the measurement value is the first sensor or the second sensor, and the sensor determined by the sensor determination unit. And a signal correction unit that corrects the magnitude of the input signal acquired from the second sensor so that the amplitude of the input signal is closer to that when the signal is acquired from the first sensor. it can.

According to such a configuration, by correcting the magnitude of the input signal according to the characteristics of the second sensor, the same can be said when using the second sensor in the seat experience device as when using the first sensor. Such an operation can be performed.

In the seat experience system described above, the seat experience device includes a sensor determination unit that determines whether the sensor connected to obtain the measurement value is the first sensor or the second sensor, and the sensor determined by the sensor determination unit. When the sensor is the first sensor, the first threshold value is set as the threshold value, and when the sensor determined by the sensor determination unit is the second sensor, the second threshold value different from the first threshold value is set. A threshold value setting unit for setting the threshold value can be provided. In this case, the motion detection unit can detect the motion of the occupant by comparing the input signal with the threshold value set by the threshold value setting unit.

According to such a configuration, by setting the threshold values according to the characteristics of the first sensor and the second sensor, the first sensor is used even when the second sensor is used in the seat experience device. It is possible to perform the same operation as when performing.

In the seat experience system described above, the first connector having a plurality of terminals connected to the first sensor, the second connector having a plurality of terminals connected to the second sensor, the first sensor and the second sensor A third connector that is connectable to both sensors and that is connected to the seat experience device may be provided. In this case, the combination of connecting the plurality of terminals of the second connector is different from the combination of connecting the plurality of terminals of the first connector, and the sensor determination unit determines that the connector connected to the third connector is the first connector. By determining which of the second connectors it is, it is possible to determine whether the connected sensor is the first sensor or the second sensor.

According to the present invention, even a person who can only perform an operation that can be detected by only one of the first sensor and the second sensor can perform the activity using the seat. As a result, various people can use the seats for activities.

Further, when the second sensor has an amplifier circuit for bringing the amplitude of the second measurement value closer to the amplitude of the first measurement value, it is not necessary to adjust the output of the input signal from the sensor.

In addition, by changing the magnitude and threshold value of the input signal according to the characteristics of the second sensor, the same operation as when using the first sensor can be performed when the second sensor is used in the seat experience device. Can be made

In addition, the seat experience device does not include an IC chip or the like having a storage medium by discriminating between the first sensor and the second sensor depending on whether the connector connected to the third connector is the first connector or the second connector. However, the type of sensor can be determined.

The pressure sensor PS6 is arranged far away from the pressure sensors PS4 and PS5. The pressure sensor PS6 is located corresponding to the upper part of the back of the seated person, and can measure the pressure value from the upper part of the back of the seated person.

In the present embodiment, the seat experience system 1 is supposed to provide a game of 100 m running using the pressure sensor PS3. In the present embodiment, the pressure sensor PS3 is an example of a first sensor that acquires a first measurement value for detecting the motion of the seated person sitting on the first seat body S10. In the game of running 100 m, the seated person sitting on the first seat body S10 alternately raises and lowers his legs to cause the pressure sensor PS3 to sense the pressure, and the display DSP of the smartphone SP is displayed according to the number of steps of raising the legs. It is assumed that the character displayed above is run and competes with the character operated by the smartphone SP or another occupant (player) for 100 m.

The seat experience device 10 includes the ECU 100 and the smartphone SP.
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. The ECU 100 is also connected to the pressure sensors PS1 to PS6 via the connector 30. The connector 30 includes a first connector 31 having a plurality of terminals, which is connected to the pressure sensors PS1 to PS6, and a third connector 33 which is connected to the seat experience device 10.
The configurations of the smartphone SP and the ECU 100 will be described later.

As shown in FIG. 2, the seat experience system 1 can be configured by connecting the second seat A2 to the seat experience device 10. The second sheet A2 is a sheet different from the first sheet A1 and is used, for example, for a physically handicapped person who cannot move his/her legs to use the seat experience device 10 like a normal person. It is a thing.

The second sheet A2 includes a second sheet body S20 and infrared sensors IS1 and IS2 as an example of a second sensor.
The second seat body S20 includes a seat cushion S1, a seat back S2, and a headrest S3 similar to those of the first seat body S10, and further includes left and right armrests S4 rotatably provided on the seatback S2.

The infrared sensors IS1 and IS2 are sensors that acquire a second measurement value for detecting the motion of a seated person who is sitting on the second seat body S20, and are a different type of sensor from the pressure sensor PS3. The infrared sensors IS1 and IS2 are provided on the second sheet body S20. Specifically, the infrared sensors IS1 and IS2 are arranged on the upper surfaces of the front end portions of the left and right armrests S4, respectively. The infrared sensors IS1 and IS2 are sensors that detect infrared rays, and when a hand is placed on the infrared sensors IS1 and IS2, the voltage output by sensing the hand of a person changes. In the present embodiment, it is assumed that the second measurement value of the infrared sensors IS1 and IS2 has a smaller signal amplitude than the first measurement value of the pressure sensor PS3.

The infrared sensors IS1 and IS2 are connected to the ECU 100 of the seat experience device 10 via the connector 30. The connector 30 includes a second connector 32 connected to the infrared sensors IS1 and IS2, and a third connector 33 connected to the ECU 100. The third connector 33 of FIG. 2 is the same as the third connector 33 shown in FIG. That is, the third connector 33 can be connected to both the first sensor and the second sensor. Further, the seat experience device 10 of FIG. 2 and the seat experience device 10 of FIG. 1 are the same. That is, the seat experience device 10 can acquire the first measurement value from the pressure sensor PS3 and can also acquire the second measurement value from the infrared sensors IS1 and IS2.

The second sheet body S20 is provided with a holder 4 for holding the smartphone SP. The holder 4 is formed by bending a wire, one end thereof is fixed to the seat back S2, and the other end thereof 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 hand. Therefore, it is possible to see the display DSP while operating the application of the smartphone SP by holding the seated person's hand over the infrared sensors IS1, IS2.

As shown in FIG. 3, the ECU 100 includes a measurement value acquisition unit 110, a processing unit 120, a communication unit 130, and a storage unit 190. The ECU 100 and the smartphone SP have a CPU, a ROM, a RAM, a rewritable nonvolatile memory, and the like (not shown), and each functional unit is realized by executing a program stored in advance.

The measurement value acquisition unit 110 has a function of acquiring pressure measurement values from the pressure sensors PS1 to PS6 and the infrared sensors IS1 and IS2 at regular control cycles. The measurement value acquired by the measurement value acquisition unit 110 is stored in the storage unit 190 and used by the processing unit 120. The storage unit 190 is used to appropriately store data necessary for calculation, processing and the like.

The processing unit 120 has a function of determining the type of sensor connected to the ECU 100, communicating with the smartphone SP, and transmitting the measured value and the type of sensor to the smartphone SP. For this reason, the processing unit 120 has a sensor determination unit 121 that determines whether the sensor connected to the ECU 100 capable of acquiring the measurement value is the pressure sensor PS3 or the infrared sensors IS1 and IS2.

Here, the sensor determination unit 121 will be described while explaining the structure of the connector 30.
As shown in FIG. 6A, the first connector 31 and the second connector 32 are, for example, 20-pin female connectors having a plurality of terminals, and the third connector 33 is the first connector 31 and It is, for example, a 20-pin male connector having a plurality of terminals that can be coupled to both the second connectors 32. The first connector 31 and the second connector 32 have holes for receiving 20 pins, but not all of the holes have valid terminals inside, and unused holes are not necessary. Is included. As described later, the combination of connecting the plurality of terminals of the second connector 32 is different from the combination of connecting the plurality of terminals of the first connector 31.

As shown in FIG. 6B, a function is assigned to each of the plurality of terminals according to each pin number (No.). 1 to 12 are signal terminals. The output value of each sensor is It is assigned to any of 1 to 12. For example, each of the pressure sensors PS1 to PS6 has a No. Nos. 1 to 12 of the infrared sensors IS1 and IS2. Assigned to 1 and 2 respectively

No. 13 is a common terminal, for example, a 5V terminal. No. of the third connector 33. The terminal 13 is a common output terminal set to a predetermined voltage. On the other hand, No. 1 of the first connector 31 and the second connector 32. Reference numeral 13 is a common input terminal that contacts the common output terminal.

No. 14 to 20 are identification terminals for identifying the type of the connected sensor. No. of the third connector 33. Reference numerals 14 to 20 denote at least one identification signal input terminal for detecting the identification voltage. On the other hand, at least one of the first connector 31 and the second connector 32 is No. 14 to 20 have at least one identification terminal which is connected to the identification signal input terminal and which is electrically connected to the common input terminal. One of the first connector 31 and the second connector 32 is No. 14 to 20 may not have an effective identification terminal (terminal connected to the identification signal input terminal).
The first connector 31 and the second connector 32 are the identification terminals of the portion corresponding to the identification signal input terminal of the third connector 33, that is, No. The arrangements of the identification terminals corresponding to 14 to 20 are different from each other.

For example, No. 1 of the first connector 31. No identification terminal to be connected to the common input terminal (No. 13) is provided in the portion of No. 14, and the No. 14 of the second connector 32 is provided. 14 is provided with an identification terminal connected to the common input terminal (No. 13). Therefore, for example, as shown in FIG. 7A, when the first connector 31 is connected to the third connector 33, the ECU 100 obtains a LOW signal, and the sensor determination unit 121 determines that the No. The ECU 100 can determine that the content assigned to LOW of 14 is a sensor of company A, for example. On the other hand, when the second connector 32 is connected to the third connector 33, the ECU 100 obtains a HIGH signal, and the sensor determination unit 121 determines that the No. The ECU 100 can determine that the content assigned to the 14 HIGHs, for example, the sensor of the B company.

Similarly, the sensor determination unit 121 determines the No. of the connector (for example, the first connector 31 and the second connector 32) connected to the third connector 33. The type of sensor can be determined by a combination of whether or not the identification terminals are provided in 15 to 17. For example, as shown in FIG. If the identification terminals are not provided in all of Nos. 15 to 17, No. Nos. 15 to 17 are all LOW signals, and it can be determined that the pressure sensor is connected. If the identification terminal is provided only on No. 17, No. Only 17 becomes HIGH, and it can be determined that the infrared sensor is connected. In addition, No. If only 16 has the identification terminal, it can be determined that the heartbeat sensor is connected. For the connector to which another sensor is connected, provide the identification terminal in a combination different from that of the pressure sensor and the infrared sensor. For example, many types of sensors can be identified. In addition, No. The types of sensors can be set to 18 to 20 in correspondence with the combination of HIGH or LOW signals.

When the ECU 100 is powered on and another connector is connected to the third connector 33, the sensor determination unit 121 determines the type of sensor corresponding to the connected connector and determines the ID of the ECU 100 (identification information). ), and the determined sensor type is transmitted to the smartphone SP.

Returning to FIG. 3, the smartphone SP has a signal correction unit 211, a motion detection unit 212, a game processing unit 213, and a storage unit 290.

When the sensors determined by the sensor determination unit 121 are the infrared sensors IS1 and IS2, the signal correction unit 211 outputs the infrared signals from the infrared sensors IS1 and IS2 so that the amplitude of the input signal becomes closer to that when the signal is obtained from the pressure sensor PS3. It has a function of correcting the magnitude of the acquired input signal.
Specifically, the signal correction unit 211 generates a corrected input signal by multiplying an input signal (value) input as a digital value by a correction coefficient. Therefore, the storage unit 290 stores, in a table, the correction coefficient to be applied to the signal (value) acquired from the sensor, corresponding to the type of the sensor. For example, the storage unit 190 stores 1 for the pressure sensor PS3, 2 for the infrared sensors IS1, IS2, and the like.

The signal correction unit 211 refers to the storage unit 290 based on the type of sensor received from the ECU 100 and acquires a correction coefficient corresponding to the sensor. Then, the input signal is multiplied by this correction coefficient to generate a corrected input signal.
For example, since the correction coefficient of the pressure sensor PS3 is 1, the signals of the input signals SI _R and SI _L as shown in FIG. 4A become the correction input signals as they are. Further, since the correction coefficients of the infrared sensors IS1 and IS2 are 2, when the input signal as shown in FIG. 5(a) is input, the value is doubled and as shown in FIG. 5(b). It becomes the correction input signal. As a result, even if the amplitude of the input signals of the infrared sensors IS1 and IS2 is small, the amplitude can be set to the same magnitude as the correction input signal of the pressure sensor PS3, and the same threshold value SIth is used for operation. Can be detected.

The motion detector 212 detects the motion of the seated person based on the acquired input signal. In the present embodiment, the motion of the seated person is detected based on the corrected input signal corrected by multiplying the input signal by the correction coefficient. Specifically, the operation detection unit 212 compares the correction input signal with the threshold value SIth, and when the correction input signal falls below the threshold value SIth (when the correction input signal changes from the base signal value to the threshold value SIth). Change), the detection signal is generated. As a result, the motion detector 212 can generate a detection signal as shown in FIG. 4B based on the measurement value of the pressure sensor PS3. Further, the operation detection unit 212 can generate a detection signal as shown in FIG. 5C based on the correction input signal of the infrared sensors IS1 and IS2 (FIG. 5B). The motion detector 212 can detect the motion of the seated person based on both the first measurement value and the second measurement value.

The game processing unit 213 has a function of processing a game using the detection signal. In the present embodiment, the game provided by the smartphone SP is a game of 100 m run, and the number of steps increases by 1 each time one detection signal is generated, and the character runs 1 m each time the number of steps increases by 1. Move the character on the display DSP of the smartphone SP. That is, the seat experience device 10 is configured to be able to perform a specific motion of moving the character in the game one step (running) based on the motion detection unit 212 detecting the motion of the seated person. There is.

Since the game itself running 100 m is not a characteristic part of the present invention, a simple example will be described. The game processing unit 213 displays a start screen displaying a game start button on the display DSP, and the seated person can play the game. Instruct the start of. When the seated person selects the button for starting the game, an explanation of how to move the character is displayed on the display DSP according to the type of the sensor received from the ECU 100. For example, when the sensor is the pressure sensor PS3, the explanation is displayed such as "Please raise your left and right legs alternately. If you move the legs alternately, the character will run faster". When the sensors are infrared sensors IS1 and IS2, the explanation is displayed such as "Shake your hand left and right on the optical sensor. If you shake your hand quickly, the character will run faster". In other words, the smartphone SP (seat experience device 10) is configured to notify the seated person that the seated person is prompted to perform an operation. Note that these descriptions may be output by voice.

Then, the game processing unit 213 performs a process of moving the character according to the detection signal until the player of the game runs 100m, and after running 100m, as a result of the game, running 100m from the start. Is configured to be displayed on the display DSP.

Next, an example of the processing of the seat experience device 10 will be described with reference to FIGS. 8 and 9.
As shown in FIG. 8, when the power is on, the ECU 100 refers to the above-mentioned table based on the signal input from the identification signal input terminal and determines the sensor connected to the third connector 33 ( S11). Then, it is determined whether or not it is connected to the smartphone SP (S12), and when it is connected (S12, Yes), the sensor type determined as the ID of the ECU is transmitted to the smartphone SP, and the process ends ( S13). On the other hand, when it is determined that the smartphone SP is not connected (S12, No), the process ends as it is.

As shown in FIG. 9, the application of the smartphone SP determines whether or not it is connected to the ECU 100 (S21), and when it is determined that it is not connected (S21, No), ends the process. On the other hand, when it is determined that the ECU 100 is connected to the ECU 100 (S21, Yes), the ECU 100 receives the ID of the ECU 100 and the sensor type from the ECU 100 (S22). Then, referring to the storage unit 290, the correction coefficient is set based on the type of sensor (S23).

Then, the game processing unit 213 prompts the seated person to start the game, and when the seated person selects the game start button, the game of 100 m running is started (S24). Then, the game processing unit 213 displays an explanation of how to move the character on the display DSP according to the type of sensor (S25).

Then, when the competition of the game of running 100 m starts, the signal correction unit 211 corrects the input signal received from the ECU 100 by multiplying it by the set correction coefficient (S26). Then, the operation detection unit 212 compares the correction input signal with the threshold value SIth and generates a detection signal when the correction input signal falls below the threshold value SIth (S27). The game processing unit 213 rewrites the image on the display DSP so that the character advances one step (1 m) each time the detection signal is generated.

Then, the processing of steps S26 and S27 is repeated until the character runs 100 m (S28, No), and when the character runs 100 m, that is, when the number of generated detection signals reaches 100 (S28, Yes). As a result of the game, the time required to run 100 m, that is, the time from the start until the number of detection signals reaches 100 is displayed on the display DSP (S29), and the process ends.

According to the seat experience system 1 of the present embodiment described above, the following effects can be obtained.

The seated person sitting on the first seat body S10 causes the seat experience apparatus 10 to perform a specific motion of running the character in the game of 100 m running by detecting the motion of moving the leg up and down by the pressure sensor PS3. You can On the other hand, a seated person sitting on the second seat body S20 causes the seat experience device 10 to run a character in a 100-m running game by detecting a motion of shaking hands with the infrared sensors IS1 and IS2. It can be operated. Therefore, even a person who can only perform an operation that can be detected by only one of the pressure sensor PS3 or the infrared sensors IS1 and IS2 can perform the activity using the seat. As a result, various people can use the seats for activities. For example, even people who do not have the same behavior can share the same community through the seat and provide an enjoyable experience.

Then, the seat experience device 10 informs the seated person that the seated person is prompted to perform an operation, so that the seated person can be operated and the seat experience system 1 can be effectively used.

Further, when the signal correction unit 211 corrects the size of the input signals of the infrared sensors IS1 and IS2 so as to approach the input signal of the pressure sensor PS3, the infrared sensors IS1 and IS2 are used in the seat experience device 10. Also, the same operation as when using the pressure sensor PS3 can be performed.

Further, the seat experience system 1 determines whether the connector connected to the third connector 33 is the first connector 31 or the second connector 32 based on the signal input from the identification signal input terminal of the third connector 33. Therefore, even if the sensor is not provided with an IC chip having a storage medium, the type of the sensor can be determined. That is, the type of sensor can be determined with a simple configuration.

As shown in FIG. 10, in the seat experience system of the second embodiment, the smartphone SP of the seat experience device 10A includes a threshold value setting unit 214 instead of the signal correction unit 211.

When the sensor determined by the sensor determination unit 121 is the pressure sensor PS3 (first sensor), the threshold value setting unit 214 sets the first threshold value as the threshold value SIth, and the sensor determination unit 121 determines. When the sensor is the infrared sensor IS1, IS2 (second sensor), a second threshold different from the first threshold is set as the threshold SIth. The second threshold value is stored in advance in the storage unit 290 of the smartphone SP according to the type of sensor, and is set so as to fall within the amplitude range of the input signals from the infrared sensors IS1 and IS2. Alternatively, the high signal value and the low signal value of the input signal within the past predetermined time are averaged and calculated, and the second threshold value is set so that the second threshold value is located between the high signal value and the low signal value. The value can also be set by calculation.

The motion detection unit 212 can detect the motion of the occupant by comparing the input signal with the threshold value set by the threshold value setting unit 214, as in the first embodiment.

In the second embodiment, as shown in FIG. 11, the smartphone SP does not perform step S23 (FIG. 9) of setting the correction coefficient, but proceeds to step S26 (FIG. 9) of correcting the input signal by applying the correction coefficient. Instead, the process of setting the threshold value may be executed (S126).

According to the second embodiment, when the input signals SI _R and SI _L as shown in FIG. 12A are input, the threshold value SIth falls within the amplitude range of the input signals SI _R and SI _L. Is set. Then, when the input signals SI _R and SI _L change from the base signal value by exceeding the threshold value SIth, a detection signal as shown in FIG. 12B can be generated.

As described above, also by the seat experience system of the second embodiment, by changing the threshold value SIth according to the characteristics of the second sensor, even when the second sensor is used in the seat experience device 10A. The same operation as that when using the first sensor can be performed. That is, the seat experience apparatus 10A can be operated in the same manner by using a plurality of different types of sensors provided in the first seat body S10.

[Third Embodiment]
Next, a third embodiment will be described. In the third embodiment, only parts different from the first embodiment will be described, and similar parts will be denoted by the same reference numerals in the drawings and description thereof will be omitted.
In the third embodiment, the infrared sensors IS1 and IS2 described in the first embodiment are used as the first sensor, and the pressure sensor PS3 is used as the second sensor. The output and amplitude of the pressure sensor PS3 are smaller than those of the infrared sensors IS1 and IS2 when the amplifier circuit 40 described later is not provided. In addition, in the third embodiment, the sheet provided with the pressure sensor PS3 is the second sheet, and the sheet provided with the infrared sensors IS1 and IS2 is the first sheet.

On such a premise, the pressure sensor PS3 has a sensor element PS3e that detects pressure and an amplifier circuit 40. The amplifier circuit 40 is a circuit that amplifies the signal of the sensor element PS3e in order to bring the amplitude of the second measurement value of the pressure sensor PS3 close to the amplitude of the first measurement value of the infrared sensors IS1 and IS2.
The amplifier circuit 40 includes a first resistor Rm, an operational amplifier OP, a first resistor Rm, a second resistor Rpu, and a third resistor Rpd. The sensor-side resistance Rfsr, which is the sensor element PS3e, is a resistance whose resistance value changes in accordance with a change in pressure as a physical quantity to be measured.

The first resistor Rm is connected in series with the sensor-side resistor Rfsr between the power supply Vpp and the ground GND. Specifically, the end of the first resistor Rm opposite to the sensor-side resistor Rfsr is connected to the ground GND, and the end of the sensor-side resistor Rfsr opposite to the first resistor Rm is connected to the power supply Vpp. ing.

The operational amplifier OP is an amplifier including a non-inverting input terminal (+), an inverting input terminal (-), and one output terminal. The non-inverting input terminal (+) is connected to the wiring between the sensor-side resistor Rfsr and the first resistor Rm. The output voltage Vout output from the output terminal is fed back to the inverting input terminal (−) via the negative feedback circuit. The second resistor Rpu is arranged in the negative feedback circuit. The third resistor Rpd is arranged between the negative feedback circuit and the ground GND.

In such an amplifier circuit 40, the amplification factor can be changed by changing the resistance values of the first resistor Rm, the second resistor Rpu, and the third resistor Rpd.

On the other hand, although illustration is omitted, the smartphone SP of the seat experience device 10 is not provided with the signal correction unit 211 in the first embodiment or the threshold value setting unit 214 in the second embodiment.

According to such a seat experience system, since the pressure sensor PS3 as an example of the second sensor in the second seat includes the amplification circuit 40, the second measurement value of the pressure sensor PS3 is the same as that of the infrared sensors IS1 and IS2. It is amplified so that the magnitude of the amplitude approaches the first output value. Therefore, even if the seat experience device does not correct the signal or set the threshold value for each type of sensor, the second seat using the pressure sensor PS3 can be used for the first seat using the infrared sensors IS1 and IS2. The seat experience device can be operated as in the case. That is, in the seat experience device, it is not necessary to adjust the output of the input signal from the sensor.

The sensors PS1 to PS6, IS1 and IS2 are connected to the seat experience device 10 via a connector 30.

Each of the sensors PS1 to PS6, IS1 and IS2 has a memory that stores the identification information (ID) of the sensor and the type of sensor such as whether it is an infrared sensor or a pressure sensor. -By referring to the memory of each sensor PS1 to PS6, IS1, IS2 via the wiring connected to PS6, IS1, IS2, the ECU 100 can identify the type of sensor connected to each wiring. Is becoming Therefore, the connector 30 does not need to prepare a terminal for identification as in the first embodiment.

Similar to the first embodiment, the smartphone SP stores the correction coefficient corresponding to the sensor type in the storage unit 290, and is configured to set the correction coefficient according to the sensor type acquired from the memory. ing.

With such a configuration, a seated person sitting on the first seat A1 can use the seat experience device 10 in the same manner by using either the pressure sensor PS3 or the infrared sensors IS1, IS2. Therefore, even a person who can only perform an operation that can be detected by only one of the pressure sensor PS3 (first sensor) or the infrared sensors IS1, IS2 (second sensor) can perform the activity using the seat. .. As a result, various people can use the seats for activities. For example, even people who do not have the same behavior can share the same community through the seat and provide an enjoyable experience.
