Then, the control device 46 sends the user information to the other mobile terminal 62, and causes the user interface 69 to display a user information screen 105 including the user information. The user information screen 105 may be, for example, Figure 7 In addition, the control device 46 may also send the user information to the navigation system 67 so that the user interface 72 displays the user information screen 105 .

[0199] In addition, the user information may be stored in at least one of the control device 46, the server 61, and the control device 68. The control device 68 selects the stored user information according to the operation of other users, generates a user information screen 105 based on the selected user information, and displays the user information screen 105 on the user interface 69. The control device 68 may display a user information selection screen showing a list of past user information on the user interface 69, so that other users can select the user information to be displayed. In this way, the user can confirm the past user information.

[0200] In addition, the server 61 may store the user information transmitted from the plurality of control devices 46. Then, the control device 68 generates the user information screen 105 based on the user information selected from the user information transmitted from the plurality of control devices 46 according to the operation of other users, and displays the user information screen 105 on the user interface 69. The control device 68 may also display the user information selection screen showing the list of user information transmitted from the plurality of control devices 46 on the user interface 69, so that other users can select the user information to be displayed. In this way, other users can confirm the user information acquired through the plurality of control devices 46.

[0246] The seat system 401 includes an interior light 441, which is provided on the roof 440 (top plate) of the upper surface that divides the vehicle compartment 402, and is a lighting device for illuminating the interior of the vehicle compartment 402. In the present embodiment, the interior light 441 is provided above and in front of each seat body 405. The interior light 441 can be turned on and off according to input signals, and its brightness can be changed. That is, the interior light 441 can be controlled to turn on, turn off, and dim.

[0247] The seat system 401 further includes a first sensor 451 and a second sensor 452 (see Fig.24). The first sensor 451 is disposed inside the seat body 405 and receives input from a user sitting on the seat body 405. The first sensor 451 is a sensor disposed on the seat cushion 410 of each seat body 405 and is used to detect that the user sits on the seating surface 413 of the seat cushion 410. That is, the first sensor 451 is a seating sensor that uses the seating surface 413 of the corresponding seat body 405 as the detection area 451S. In the present embodiment, the first sensor 451 is composed of a pressure sensor that detects the pressure of the seating surface 413 (upper surface) of the seat cushion 410. The first sensor 451 can detect changes in pressure corresponding to the rise and fall of the knees of the user sitting on the seat body 405. However, the first sensor 451 may also be other sensors, for example, it may also include a plurality of membrane switches that are disposed on the seat cushion 410 or the seat back 411 and become turned on when the user sits down. In addition, the first sensor 451 may be a proximity sensor provided on the seat cushion 410 or the seat back 411 for detecting the approach of the user, or a touch sensor for detecting the contact (touch) of the user on the seat back 411. In addition, the first sensor 451 may be a temperature sensor for detecting the temperature change of the surface of the seat cushion 410 or the seat back 411 due to the contact of the user. In addition, the first sensor 451 may be a humidity sensor for detecting the change of humidity of the surface of the seat cushion 410 or the seat back 411 due to the contact of the user.

[0248] The second sensor 452 may be provided at a position that can be touched (within the range of action) by a user sitting on the seat body 405, or may be provided on any component that divides the vehicle compartment 402. The second sensor 452 is a sensor for detecting contact between a user and a predetermined area (hereinafter referred to as a touch area 452S) on the surface of the component on which the sensor is provided. The second sensor 452 may detect the contact of the user based on at least one of the pressure applied to the touch area 452S due to the contact of the user, the load applied to the touch area 452S above a threshold, the user approaching the touch area 452S, the temperature change of the touch area 452S due to the contact of the user, and the humidity change of the touch area 452S due to the contact of the user. That is, the second sensor 452 may include at least one of a pressure sensor that detects the pressure applied to the touch area 452S, a membrane switch that is turned on due to the load applied to the touch area 452S, a proximity sensor that detects the approach to the touch area 452S, a temperature sensor that detects the temperature of the touch area 452S, and a humidity sensor that detects the humidity of the touch area 452S.

[0249] In this embodiment, if Fig.24As shown, the second sensor 452 includes a sensor 453, which is arranged inside the front seat body 405A, and the upper back portion of the seat back 411 of the front seat body 405A is used as a touch area 453S. In addition, the second sensor 452 includes a sensor 454, which is arranged inside the middle seat body 405B, and the upper back portion of the seat back 411 of the middle seat body 405B is used as a touch area 454S. Fig.23 As shown, the second sensor 452 further includes sensors 455 and 456, whose touch areas 455S and 456S are provided on the side surfaces of the door trims 417 and 418 on the vehicle interior side, respectively; a sensor 457, whose touch area 457S is provided on the side surface of the rear trim 419 on the vehicle interior side; and a sensor 458, whose touch area 458S is provided on the surface of the instrument panel 420 on the vehicle interior side. The second sensor 452 may further include a sensor 459, which is provided on the roof 440 (top plate), and whose touch area 459S is provided on the surface of the roof 440 on the vehicle interior side. The second sensor 452 may further include a sensor 461, which is provided on a pillar 460 constituting a window pillar, and whose touch area 461S is provided on the surface of the pillar 460 on the vehicle interior side. The touch areas 458S, 459S, and 461S may be provided at positions that can be contacted (touched) by a user sitting on any seat body 405.

[0250] The seat system 401 further includes a control device 470, which is connected to the first sensor 451, the second sensor 452, the front-rear moving actuator 436, the tilting actuator 437, and the interior light 441, respectively. The control device 470 is an electronic control unit (ECU) composed of a microcomputer, ROM, RAM, peripheral circuits, an input / output interface, a driver, etc. The control device 470 receives signals from the first sensor 451 and the second sensor 452, and sends signals to the front-rear moving actuator 436, the tilting actuator 437, and the interior light 441, so that the front-rear moving actuator 436, the tilting actuator 437, and the interior light 441 output signals appropriately, thereby controlling the front-rear moving actuator 436, the tilting actuator 437, and the interior light 441, respectively.

[0251] The seat system 401 also has an application execution device 472 held by the user on the vehicle. The application execution device 472 is a so-called smart phone having a touch screen 473, a memory, and a central processing unit (hereinafter referred to as the processing device 474). The touch screen 473 functions as a display unit that displays information, and functions as an input unit that accepts input based on user contact. The processing device 474 can communicate with the control device 470 provided in the vehicle S via wireless, thereby receiving the detection results of the first sensor 451 and the second sensor 452. In addition, the processing device 474 can control the front and rear movement actuator 436, the tilting actuator 437 and the interior light 441 respectively by sending a specified signal to the control device 470.

[0252] The processing device 474 can execute a 100-meter running game application program for moving a character displayed on the touch screen 473 according to the user's input to the sensor (see Fig.26 (A) and Fig. 27 (C) in the following. Fig.25 , Fig.26 and Fig. 27 To illustrate the details of the processing performed in the game application executed by the processing device 474.

[0253] First, if Fig.25 As shown, the processing device 474 causes the touch screen 473 to display a participation acceptance screen 480 (see Fig.26 In (A) of FIG. 1 , an input indicating the user's intention to participate is accepted ( ST1 ). The participation acceptance screen 480 includes an input button “Yes” corresponding to the user's intention to participate and an input button “No” corresponding to the user's intention not to participate.

[0254] When the processing device 474 detects that the "Yes" button is touched on the participation acceptance screen 480, Fig.25 As shown, the processing device 474 causes the touch screen 473 to display a sensor selection screen 481 (see Fig.26 In (B)), a selection acceptance process (ST2) is executed for allowing the user to select a sensor for operation input (hereinafter referred to as an operation input sensor). When the processing device 474 detects that the input button "No" is touched on the participation acceptance screen 480, the application is terminated.

[0255] In the selection acceptance process, the processing device 474 first performs wireless communication with the control device 470 based on, for example, Bluetooth (registered trademark) to obtain the position of the application execution device 472. The processing device 474 estimates the seated position of the user holding the application execution device 472 based on the acquired position of the application execution device 472. Next, the processing device 474 estimates the surface on which the user is sitting, that is, the seat surface 413, based on the estimated seated position of the user, and determines the first sensor 451 that detects the touch of the seat surface 413 as the first input sensor.

[0256] Furthermore, the processing device 474 extracts a sensor that is accessible to the seated user and disposed outside the seat body 405 where the user is seated from the second sensors 452 based on the estimated seated position of the user, and determines it as the second input sensor. In the present embodiment, the processing device 474 determines the second front input sensor and the second lateral input sensor as two second input sensors from the second sensors 452. More specifically, the processing device 474 determines the sensor that is located in front of the user and accessible to the seated user as the second front input sensor, and determines the sensor that is located to the side of the user and accessible to the seated user as the second lateral input sensor.

[0257] In this embodiment, when the user's seated position is located in the middle seat body 405B (rear seat body), the processing device 474 determines the first sensor 451 provided on the seat cushion 410 of the middle seat body 405B as the first input sensor. In addition, the processing device 474 determines the second sensor 452 provided on the upper back side of the seat back 411 of the front seat body 405A (front seat body) on the front side of the middle seat body 405B where the user is seated as the second front input sensor. The second front input sensor is used to detect the contact between the user and the upper back side of the seat back 411 of the front seat body 405A.

[0258] When the user's sitting position is the front seat body 405A, the second sensor 452 for detecting contact with the instrument panel 420 is determined as the second front input sensor. When the user's sitting position is the rear seat body 405C, the second sensor 452 provided on the upper back portion of the seat back 411 of the middle seat body 405B and for detecting contact between the user and the upper back portion of the seat back 411 of the middle seat body 405B is determined as the second front input sensor.

[0259] In this embodiment, when the user's seated position is the middle seat body 405B, the processing device 474 determines the second sensor 452 provided on the door trim 417 of the rear door 416 located on the side of the middle seat body 405B as the second lateral input sensor. Similarly, when the user sits on the front seat body 405A, the second sensor 452 provided on the door trim 418 of the front door 415 located on the side of the front seat body 405A is determined as the second lateral input sensor. When the user sits on the rear seat body 405C, the second sensor 452 provided on the rear side trim 419 located on the side of the rear seat body 405C is determined as the second lateral input sensor.

[0260] Next, the processing device 474 displays the positions of the first sensor 451, the second front sensor, and the second lateral sensor on the touch screen 473. Fig.26 As shown in (B) in FIG. 4 , the processing device 474 can construct an image of the interior of the vehicle 402 according to the user's seating position and display it on the touch screen 473 .

[0261] At the same time, if Fig.26 As shown in (B) in the figure, the processing device 474 causes the touch screen 473 to display the button "A" corresponding to the first sensor 451, the button "B" corresponding to the second front sensor, and the button "C" corresponding to the second lateral sensor. After that, the processing device 474 accepts the user's selection by detecting the touch of each button on the touch screen 473. When the processing device 474 detects the touch of button "A", button "B" or button "C" in the sensor selection screen 481, the processing device 474 saves the user's selection result as the ID of the operation input sensor in the memory, and completes the selection acceptance process. At this time, in the present embodiment, the processing device 474 stores the ID of the button detected to be touched (for example, "A", "B", "C", etc.) as the ID of the operation input sensor in the memory.

[0262] When the selection acceptance process is completed, the processing device 474 determines whether the user's seat position is the front seat body 405A or the middle seat body 405B (ST3). When the seat position is the front seat body 405A or the middle seat body 405B, the automatic adjustment of the seat body 405 is accepted (ST4). When the seat position is the rear seat body 405C, the automatic adjustment of the seat body 405 is not accepted, but the automatic adjustment of the interior light 441 is accepted.

[0263] like Fig.25 As shown, when the automatic adjustment of the seat body 405 is accepted, the processing device 474 causes the touch screen 473 to display the seat adjustment acceptance screen 482 (see Fig.26In (C)), an input indicating that the user wishes to perform the seat adjustment process is accepted (ST4). In the seat adjustment acceptance screen 482, an input button "Yes" corresponding to the intention to perform the automatic adjustment of the seat body 405 and an input button "No" corresponding to the intention not to perform the automatic adjustment of the seat body 405 are displayed.

[0264] When the touch of the button "Yes" is detected in the seat adjustment acceptance screen 482, the processing device 474 performs a seat adjustment process, which is to drive the actuator 435 of the adjustment mechanism 425 to displace the seat body 405 on which the user is sitting so as to facilitate the user to play the game (ST5). The so-called displacement here includes parallel movement, rotation and deformation of the seat body 405, at least including the front and rear movement of the seat cushion 410 relative to the floor 403 and the tilting of the seat back 411 relative to the seat cushion 410. In this embodiment, when the touch of the button "Yes" is detected in the seat adjustment acceptance screen 482, the processing device 474 drives the front and rear movement actuator 436 through the control device 470 to move the seat body 405 on which the user is sitting as far as possible to the rear. In addition, the processing device 474 drives the tilting actuator 437 through the control device 470 to tilt the seat back 411 of the seat body 405 on which the user is sitting as far as possible to the front relative to the seat cushion 410 of the seat body 405 on which the user is sitting. As a result, the seat back 411 is in an upright position.

[0265] When the adjustment mechanism 425 includes the rotation mechanism 428, the processing device 474 can rotate the seat body 405 during the seat adjustment process, so that the seat body 405 is displaced (moved) to a position that is convenient for the user to play the game. More specifically, the processing device 474 can rotate the seat body 405 in a manner that faces forward during the seat adjustment process. Accordingly, an environment in which the user can enjoy the game better can be provided.

[0266] When the displacement of the seat body 405 is completed, as shown in FIG. Fig.25 As shown, the processing device 474 displays a vehicle interior light adjustment acceptance screen 483 (see Fig. 27 In (A)), an input indicating that the user wishes to perform automatic adjustment of the interior lighting of the vehicle is accepted (ST6).

[0267] When the touch of the "Yes" button is detected in the interior light adjustment acceptance screen 483, the processing device 474 turns off the interior light 441 (ST7). Fig.25 As shown, the processing device 474 causes the touch screen 473 to display a game execution screen 484 (see Fig. 27(B) in the figure). When a touch of the “No” button is detected on the interior light adjustment acceptance screen 483 , the processing device 474 displays the game execution screen 484 on the touch screen 473 without switching the interior light 441 on and off.

[0268] When displaying the game execution screen 484, the processing device 474 refers to the memory to obtain the ID of the operation input sensor selected by the user. Thereafter, the processing device 474 performs execution processing of the application program for executing a 100-meter run according to the signal detected by the operation input sensor selected by the user, and the 100-meter run refers to moving the character displayed on the touch screen 473 toward the finish line (ST8). More specifically, when the ID corresponding to the A button is stored in the memory as the ID of the operation input sensor, the processing device 474 obtains the signal detected by the first input sensor through the control device 470. Thereafter, the processing device 474 moves the character displayed on the touch screen 473 according to the signal detected by the first input sensor. In the present embodiment, the processing device 474 may be configured to move the character forward according to the rise and fall of the knees of the user sitting on the seat body 405 detected by the first input sensor.

[0269] When the ID corresponding to the B button is stored in the memory as the ID of the operation input sensor, the processing device 474 moves the character according to the signal detected by the second front input sensor. More specifically, the control device 470 can move the character forward according to the user's contact (touch) detected by the second front sensor.

[0270] When the ID corresponding to the C button is stored in the memory as the ID of the operation input sensor, the processing device 474 moves the character according to the signal detected by the second lateral sensor. More specifically, the control device 470 can move the character forward according to the user's contact (touch) detected by the second lateral input sensor.

[0271] However, the processing device 474 can change the movement amount of the character according to the size of the signal detected by the operation input sensor. When the character reaches the end point, the processing device 474 causes the touch screen 473 to display a result display screen 485 (see Fig. 27 (C) in the figure, after which the application is terminated.

[0272] Next, the operation of the seat system 401 thus configured will be described. For example, when a user sitting on the middle seat body 405B starts an application for a 100-meter running game, a participation acceptance screen 480 is displayed on the touch screen 473 of the application execution device 472. When the user touches the button "Yes", a sensor selection screen 481 is displayed. At this time, the processing device 474 selects a sensor that detects contact between the user and the seat surface 413 where the user is sitting from the first sensor 451 and sets it as the first input sensor. In addition, the processing device 474 sets a sensor that is provided on the back surface of the seat back 411 of the front seat body 405A and is used to detect contact between the user and the back surface as the second front input sensor. In addition, the processing device 474 sets a sensor that is provided on the door trim 418 of the rear door 416 located on the side of the middle seat body 405B and is used to detect contact between the user and the surface on the inside of the vehicle as the second lateral input sensor. After that, the processing device 474 causes the touch screen 473 to display the positions of the first input sensor, the second front input sensor, and the second lateral input sensor and the buttons corresponding to each other on the sensor selection screen 481. Accordingly, the user can select an operation input sensor from the first input sensor, the second front input sensor, and the second lateral input sensor.

[0273] After that, when the user touches the button displayed on the sensor selection screen 481 and selects the sensor, the processing device 474 causes the touch screen 473 to display the seat adjustment acceptance screen 482. When the user touches the button "Yes" displayed on the seat adjustment acceptance screen 482, the middle seat body 405B moves as far back as possible. Accordingly, the distance between the front seat body 405A and the middle seat body 405B becomes larger, and the middle seat body 405B where the user sits is arranged in a position where the user can easily move his legs up and down. At the same time, the seat back 411 of the middle seat body 405B where the user sits stands up relative to the seat cushion 410, and the middle seat body 405B becomes a shape in which the user can easily move his legs up and down. Accordingly, the application execution device 472 can adjust the seat body 405 to a position and shape in which the user in the car can better enjoy the game. That is, the position and shape of the seat body 405 can be adjusted to be suitable for using the application, thereby providing the user with an environment to better enjoy the game.

[0274] Next, the processing device 474 causes the touch screen 473 of the application execution device 472 to display the interior light adjustment acceptance screen 483. When the user touches the "Yes" button on the interior light adjustment acceptance screen 483, the interior light 441 is turned off. As a result, the user can easily recognize the screen display of the touch screen 473. As a result, an environment in which the user can enjoy the game better is provided.

[0275] After that, the processing device 474 causes the touch screen 473 to display the game execution screen 484. The user moves the character by inputting to the operation input sensor selected by the user. That is, the operation input sensor selected from the first sensor 451 and the second sensor 452 constitutes the application controller of the application execution device 472. When the character reaches the finish line, the processing device 474 ends the 100-meter running game application.

[0276] Next, the effect of the seat system 401 constructed in this way will be described. On the sensor selection screen 481, the user can select an operation input sensor from the first input sensor, the second front input sensor, and the second lateral input sensor, which is a sensor for performing input for operating a character. Accordingly, compared with the case where only the first sensor 451 is provided in the car 402, the number of sensors to which the user can perform input can be increased. Therefore, for example, a user with mobility impairments can select the second front sensor or the second lateral sensor to enjoy the game. That is, the seat system 401 can provide operation input methods corresponding to more users. In addition, the operation mechanism of the game application executed by the application execution device 472 can be increased. Accordingly, more users can enjoy the game application, so that more colorful applications can be provided to the users.

[0277] The sensor provided on the seat cushion 410 of the seat body 405 where the user sits is set as the first input sensor. Accordingly, the first sensor 451 can be provided at a position where the user can easily input. In addition, the user can operate the game application while sitting on the seat body 405, thereby facilitating the operation of the game application.

[0278] The sensor provided on the dashboard 420 or the back of the seat back 411 located in front of the seat body 405 where the user sits is set as the second front input sensor. Thus, the sensor provided at a position where the user can easily perform input can be set as the second front input sensor.

[0279] The sensor provided on the door trim 417, 418 or the rear trim 419 located on the side of the seat body 405 where the user sits is set as the second lateral input sensor. Thus, the sensor provided at a position where the user can easily perform input can be set as the second lateral input sensor.

[0280] In the above-mentioned embodiment, the game application includes a selection process and an execution process, wherein the selection process refers to a process of allowing the user to select at least one sensor from the first sensor 451, the second front sensor, and the second lateral sensor; and the execution process refers to a process of moving the character according to the signal from the selected sensor. Accordingly, even if the user accidentally touches a sensor other than the selected sensor, the character does not move, and erroneous actions caused by input to sensors other than the selected sensor can be prevented. In addition, the user can select the sensor used to operate the game application, that is, the operation input sensor, from the first input sensor and the second input sensor, so the user can select the sensor suitable for operating the game application.

[0281] (11th embodiment) The 11th embodiment is different from the 10th embodiment in the structure of the application execution device 472 of the seat system 501, the details of the selection acceptance process, the seat adjustment process and the execution process included in the 100-meter running game application, and the other structures are the same as the 10th embodiment. Therefore, the description of the other structures is omitted.

[0282] like Fig.28 As shown, the application execution device 472 involved in this embodiment has a GPS receiver 502, and the processing device 474 of the application execution device 472 can communicate through a public line and connect to a server 504 storing weather information via a network 503 such as the Internet.

[0283] In the selection acceptance process, the processing device 474 receives a signal from an artificial satellite through the GPS receiver 502, thereby acquiring the position of the application execution device 472. After that, the processing device 474 is connected to the server 504 storing weather information through the network 503. After that, the processing device 474 acquires the predicted outdoor temperature at the position of the application execution device 472 from the server 504. When the predicted outdoor temperature is above a predetermined threshold, the processing device 474 selects the first sensor 451 and stores the ID of the first sensor 451 as the selection result in the memory. At this time, since the outdoor temperature is above the threshold, the processing device 474 causes the touch screen 473 to display a screen notifying the user that the operation input sensor is selected by the processing device 474 because the outdoor temperature is above the threshold. When the predicted outdoor temperature is lower than the predetermined threshold, the positions of the first input sensor, the second front input sensor, and the second lateral input sensor and buttons "A" to "C" are displayed on the touch screen 473 in the same manner as in the tenth embodiment. Thereafter, the processing device 474 receives the user's selection of the operation input sensor by detecting the touch of each button on the touch screen 473, and stores the ID of the operation input sensor in the memory.

[0284] The processing device 474 controls the workload of the adjustment mechanism 425 in the seat adjustment process based on the information from the server 504. More specifically, in the seat adjustment process, when the outdoor temperature is above the threshold, the processing device 474 controls the workload of the tilt actuator 437 in such a manner that the seat back 411 is located at a position slightly tilted backward relative to the seat cushion 410, thereby deforming the seat body 405, compared with a case where the outdoor temperature is less than the threshold.

[0285] During the execution process, when the outdoor temperature is above the threshold, the processing device 474 moves the person earlier relative to the input to the first input sensor, compared to the case where the outdoor temperature is below the threshold. That is, during the execution process, when the outdoor temperature is above the threshold, the processing device 474 increases the speed of the person's movement relative to the input to the first input sensor.

[0286] The action and effect of the seat system 501 involved in the eleventh embodiment are explained. In the selection acceptance process, when it is predicted that the outdoor temperature is above the threshold, such as in summer, the processing device 474 selects the first sensor 451 as the operation input sensor. Accordingly, compared with the case where the user inputs to the second front sensor or the second lateral sensor, the amount of movement performed by the user in the game can be reduced. Accordingly, when the predicted outdoor temperature reaches above the threshold, such as in summer, the user can be prevented from excessively consuming physical energy due to playing games. On the other hand, when the outdoor temperature is less than the threshold, the user himself selects the operation input sensor from the first input sensor, the second front input sensor, and the second lateral input sensor.

[0287] In this way, in the seat system 501 involved in the eleventh embodiment, the operation input sensor is selected based on the information related to the user's surrounding environment stored in the server 504, that is, the outdoor temperature. That is, in the seat system 501, a sensor suitable for the user's surrounding environment can be selected as the operation input sensor, and the user operates the game application by inputting to the operation input sensor. Accordingly, the usability of the seat system 501 is improved.

[0288] Furthermore, in this embodiment, when the outdoor temperature is above the threshold, the moving speed of the character relative to the input to the first input sensor is increased. This can reduce the amount of movement performed by the user in the game, thereby providing an environment more suitable for the user.

[0289] When the outdoor temperature is above the threshold, the seat back 411 is located at a position slightly tilted backward relative to the seat cushion 410. Accordingly, when the outdoor temperature is above the threshold, a gap is easily formed between the back of the user and the seat back 411. Accordingly, the user can enjoy the game in a cooler environment, and the seat body 405 has a shape that is more suitable for the user. That is, the processing device 474 can control the tilt actuator 437 according to the user's condition based on the information from the server 504, so that the user can be provided with an environment in which the user can enjoy the game better.

[0290] (12th embodiment) The seat system 601 according to the 12th embodiment is different from the seat system 401 according to the 10th embodiment in that it includes a speaker 602. In addition, in the 12th embodiment, the content of the game executed in the application execution device 472 is different from that in the 10th embodiment, and the participation acceptance screen 480, the selection acceptance process, and the execution process are different. The other structures of the 12th embodiment are the same as those of the 10th embodiment, and therefore the description thereof is omitted.

[0291] like Fig.29As shown, the seat system 601 includes: a speaker 602A, which is provided on the door trim 417 of the left and right front doors 415; a speaker 602B, which is provided on the door trim 418 of the left and right rear doors 416; and a speaker 602C, which is provided on the left and right rear side trims 419. The speakers 602A, 602B, and 602C are respectively connected to the side surfaces of the corresponding door trims 417, 418 or the rear side trims 419 on the vehicle exterior side, and are connected to the control device 470 through a predetermined signal line. Each speaker emits a sound to the interior of the vehicle compartment 402 according to a signal from the control device 470. That is, the control device 470 can control the sound output from each speaker 602A, 602B, and 602C. The control device 470 receives a signal from the processing device 474 of the application execution device 472, and outputs a signal to each speaker.

[0292] The game application executed in the application execution device 472 is shown in the game execution screen 684 (see Fig.30 ) is a gaming application in which the user can input music into the sensor.

[0293] In the selection acceptance process, similarly to the tenth embodiment, the processing device 474 displays the first input sensor, the second front input sensor, and the second lateral input sensor on the sensor selection screen 481 to accept the user's selection of the two operation input sensors. The processing device 474 stores the IDs of the two operation input sensors in the memory.

[0294] In the execution process, the processing device 474 first obtains the seat position of the user holding the application execution device 472, and extracts the speaker 602 closest to the seat position as the output speaker. After that, the processing device 474 causes the output speaker to output the specified music. At this time, the processing device 474 displays the game execution screen 684 corresponding to the music (see Fig.30 ), and simultaneously acquires signals from two operation input sensors through the control device 470. The processing device 474 can make the game execution screen 684 display the input instructions of the user to the operation input sensors at this time. In addition, the processing device 474 calculates the consistency between the music and the time when the user inputs to the operation input sensors respectively based on the signals from the two operation input sensors, and displays the result on the screen.

[0295] The effect of the seat system 601 involved in the twelfth embodiment is described. The seat system 601 involved in the twelfth embodiment includes a speaker 602, so it is possible to configure a game application that inputs to the operation input sensor according to sound. In addition, in order to appropriately execute the game, the application execution device 472 can emit sound from the speaker 602 through the control device 470. According to this, the application execution device 472 can provide an environment that makes the user feel more realistic and can better enjoy the game. That is, the application execution device 472 can provide the user with an environment suitable for using the application execution device 472.

[0296] The processing device 474 performs execution processing based on the signals from the two operation input sensors. Thus, the game application executed by the application execution device 472 can be operated based on the signals from the plurality of operation input sensors. Thus, the types of game applications that can be provided to the user can be increased.

[0297] The above is the end of the description of the specific implementation method, but the present invention is not limited to the above implementation method, and can be implemented in a significantly modified manner. In the above implementation method, an example of applying the seat system to a vehicle is described, but the seat system can also be applied to seats for other means of transportation other than automobiles, and seats installed in buildings such as theaters and houses.

[0298] The signal processing unit 56 determines whether a child seat or a child booster seat is mounted on the seat body 5 based on the signal from the sensor 40. When a child seat or a child booster seat is mounted, the output from the signal processing unit 56 to the application processing unit 57 may be set to 0. When the sensor 40 has a load sensor (pressure sensor), the signal processing unit 56 may detect whether a child seat or a child booster seat is mounted on the seat body 5 based on the load distribution detected by the sensor 40. For example, when the load distribution detected by the sensor 40 is consistent with a preset pattern, it can be determined that a child seat or a child booster seat is mounted on the seat cushion 7 of the seat body 5.

[0299] In addition, the child seat or child booster seat mounted on the seat body 5 may also have a sensor capable of sending a signal to the control device 46 through wireless communication. The sensor of the child seat or child booster seat may be the same as the sensor 40 applied to the seat body 5. When the signal processing unit 56 detects that the child seat or child booster seat is placed on the seat body 5, the output based on the signal from the sensor 40 of the seat body 5 is set to 0, thereby outputting the signal from the sensor provided in the child seat or child booster seat to the application processing unit 57. In this way, the user sitting in the child seat or child booster seat can also play the game.

[0300] In the above embodiment, an example of applying the seat system to a vehicle is described, but the seat system can also be applied to seats for other means of transportation other than automobiles, and seats installed in buildings such as theaters and houses. In addition, in the above embodiment, an example of using a disc frame 224 in the seat cushion frame 211 as a pressure-bearing component that can support the seated person is described, but the disc frame 224 can also be changed to other pressure-bearing components. The pressure-bearing component is a component that connects the front member 222 and the rear member 223, and can be, for example, a component formed by connecting a plurality of S-shaped springs or a plurality of wires with resin. The second control device 250 and the third control device 262 can also be supported by a pressure-bearing component such as an S-shaped spring.

[0301] In the tenth and eleventh embodiments, an example of executing a 100-meter running game application program is described by using a single application program execution device 472, but the present invention is not limited to this method. For example, the application program execution devices 472 may be configured to be able to communicate with each other wirelessly, and a plurality of application program execution devices 472 may simultaneously execute the 100-meter running game application program.

[0302] More specifically, when two users are seated on the middle seat body 405B, the two users can simultaneously enjoy the 100-meter running game. In this case, when the game application is started in one application execution device 472, the application execution device 472 notifies the other application execution devices 472 in the vehicle. Fig.31 As shown, the application execution device 472 may be configured to display characters corresponding to respective users on the touch screen 473, and to move the characters forward according to inputs to the respective operation input sensors. Thus, the users can select the operation input sensors suitable for them, and thus, a plurality of people including users with physical disabilities who find it difficult to input to the seat sensor can enjoy the game at the same time.

[0303] In the above embodiment, the seat systems 401, 501, and 601 installed in the vehicle S are described, but the present invention is not limited to this embodiment.
