The seat system 1 further includes a control device 70 connected to each of the first sensors 51, each of the second sensors 52, each of the fore-aft movement actuators 36, each of the tilt actuators 37, and each of the interior lights 41. The control device 70 is an electronic control unit (ECU) that is composed of a microcomputer, ROM, RAM, peripheral circuits, an input/output interface, drivers, etc. The control device 70 receives signals from the first sensors 51 and the second sensors 52, and transmits signals to the fore-aft movement actuators 36, the tilt actuators 37, and the interior lights 41 to control them by outputting them appropriately.

The seat system 1 further includes an application execution device 72 held by the user who is seated in the vehicle. The application execution device 72 is a so-called smartphone equipped with a touch panel 73, a memory, and a central processing unit (hereinafter, the processing unit 74). The touch panel 73 functions as a display unit that displays information, and also functions as an input unit that accepts input by touch from the user. The processing unit 74 wirelessly communicates with a control device 70 provided in the vehicle S, and can obtain the detection results of the first sensor 51 and the second sensor 52. The processing unit 74 can also control the forward/rearward movement actuator 36, the tilt actuator 37, and the interior light 41 by transmitting a predetermined signal to the control device 70.

The processing device 74 is capable of executing a 100m sprint game application that moves a character displayed on the touch panel 73 in response to user input to the sensor (see FIG. 4(A) and FIG. 5(C)). Below, the details of the processing performed in the game application executed by the processing device 74 will be described with reference to FIG. 3, FIG. 4, and FIG. 5.

As shown in FIG. 3, the processing device 74 first displays on the touch panel 73 a participation acceptance screen 80 (see FIG. 4(A)) into which the user's intention to participate is input, and accepts input from the user indicating the intention to participate (ST1). The participation acceptance screen 80 includes a "Yes" input button corresponding to the intention to participate and a "No" input button corresponding to the intention not to participate.

When the processing device 74 detects a touch on the "Yes" input button on the participation acceptance screen 80, as shown in FIG. 3, the processing device 74 displays a sensor selection screen 81 (see FIG. 4(B)) on the touch panel 73, and executes a selection acceptance process (ST2) that allows the user to select one sensor (hereinafter, operation input sensor) that will perform operation input. When the processing device 74 detects a touch on the "No" input button on the participation acceptance screen 80, it ends the application.

In the selection reception process, the processing device 74 first acquires the position of the application execution device 72 by wirelessly communicating with the control device 70, for example, via Bluetooth (registered trademark). The processing device 74 estimates the seating position of the user holding the application execution device 72 from the acquired position of the application execution device 72. Next, the processing device 74 estimates the surface on which the user sits, i.e., the seating surface 13, based on the estimated seating position of the user, and determines the first sensor 51, which detects touch on the seating surface 13, to be the first input sensor.

Furthermore, based on the estimated seating position of the user, the processing device 74 extracts from the second sensors 52 sensors that are reachable by the seated user and that are provided outside the seat body 5 on which the user is seated, and determines the second input sensor. In this embodiment, the processing device 74 determines two second input sensors, a second front input sensor and a second lateral input sensor, from the second sensors 52. More specifically, the processing device 74 determines a sensor located in front of the user and reachable by the seated user as the second front input sensor, and a sensor located to the side of the user and reachable by the seated user as the second lateral input sensor.

In this embodiment, when the user is seated in the mid-seat body 5B (rear seat body), the processing device 74 determines the first sensor 51 provided on the seat cushion 10 of the mid-seat body 5B as the first input sensor. Furthermore, the processing device 74 determines the second sensor 52 provided on the upper back surface of the seat back 11 of the front seat body 5A (front seat body) in front of the mid-seat body 5B where the user is seated as the second front input sensor. The second front input sensor detects the user's contact with the upper back surface of the seat back 11 of the front seat body 5A.

When the user is seated in the front seat body 5A, the second sensor 52 that detects contact with the instrument panel 20 is determined to be the second front input sensor. When the user is seated in the rear seat body 5C, the second sensor 52 that is provided on the upper back surface of the seat back 11 of the mid-seat body 5B and detects contact of the user with the upper back surface of the seat back 11 of the mid-seat body 5B is determined to be the second front input sensor.

In this embodiment, when the user is seated in the mid-seat body 5B, the processing device 74 determines the second sensor 52 provided on the door trim 17 of the rear door 16 located to the side of the mid-seat body 5B as the second lateral input sensor. Similarly, when the user is seated in the front seat body 5A, the processing device 74 determines the second sensor 52 provided on the door trim 18 of the front door 15 located to the side of the front seat body 5A as the second lateral input sensor. When the user is seated in the rear seat body 5C, the processing device 74 determines the second sensor 52 provided on the rear side trim 19 located to the side of the rear seat body 5C as the second lateral input sensor.

Next, the processing device 74 displays the positions of the first sensor 51, the second front sensor, and the second lateral sensor on the touch panel 73. At this time, as shown in FIG. 4(B), the processing device 74 may generate an image of the interior of the vehicle compartment 2 based on the user's seating position and display it on the touch panel 73.

At the same time, as shown in FIG. 4(B), the processing device 74 displays on the touch panel 73 an "A" button corresponding to the first sensor 51, a "B" button corresponding to the second front sensor, and a "C" button corresponding to the second side sensor. The processing device 74 then detects a touch on each button on the touch panel 73 to accept the user's selection. When the processing device 74 detects a touch on the "A" button, the "B" button, or the "C" button on the sensor selection screen 81, the processing device 74 saves the user's selection result in memory as the ID of the operation input sensor, and completes the selection acceptance process. At this time, in this embodiment, the processing device 74 stores in memory the ID (e.g., "A", "B", "C", etc.) indicating the button on which the touch was detected as the ID of the operation input sensor.

When the selection reception process is completed, the processing device 74 determines whether the user's seating position is the front seat body 5A or the mid-seat body 5B (ST3). If the seating position is the front seat body 5A or the mid-seat body 5B, the automatic adjustment of the seat body 5 is received (ST4). If the seating position is the rear seat body 5C, the automatic adjustment of the interior light 41 is received without receiving the automatic adjustment of the seat body 5.

As shown in FIG. 3, when accepting an automatic adjustment of the seat body 5, the processing device 74 displays a seat adjustment acceptance screen 82 (see FIG. 4(C)) on the touch panel 73 and accepts an input indicating the user's intention to execute the seat adjustment process (ST4). On the seat adjustment acceptance screen 82, a "Yes" input button is displayed, which corresponds to the intention to execute the automatic adjustment of the seat body 5, and a "No" input button is displayed, which corresponds to the intention not to execute the automatic adjustment of the seat body 5.

When the "Yes" button is touched on the seat adjustment reception screen 82, the processing device 74 drives the actuator 35 of the adjustment mechanism 25 to perform a seat adjustment process that displaces the seat body 5 on which the user sits so that the user can easily play the game (ST5). The displacement here includes translation, rotation, and deformation of the seat body 5, and includes at least the forward and backward movement of the seat cushion 10 relative to the floor 3 and the tilting of the seat back 11 relative to the seat cushion 10. In this embodiment, when the "Yes" button is touched on the seat adjustment reception screen 82, the processing device 74 drives the forward and backward movement actuator 36 via the control device 70 to move the seat body 5 on which the user sits as far back as possible. Furthermore, the processing device 74 drives the tilting actuator 37 via the control device 70 to tilt the seat back 11 of the seat body 5 on which the user sits as far forward as possible relative to the seat cushion 10 of the seat body 5 on which the user sits. As a result, the seat back 11 is in an upright position.

If the adjustment mechanism 25 includes a rotation mechanism 28, the processing device 74 may rotate the seat body 5 in the seat adjustment process to displace (move) the seat body 5 to a position that makes it easier for the user to play the game. More specifically, the processing device 74 may rotate the seat body 5 so that it faces forward in the seat adjustment process. This provides the user with an environment in which to better enjoy the game.

When the displacement of the seat body 5 is complete, as shown in FIG. 3, the processing device 74 displays an interior light adjustment reception screen 83 (see FIG. 5(A)) that receives the automatic adjustment of the interior light 41, and receives an input indicating the user's desire to perform automatic interior light adjustment (ST6).

When the processing device 74 detects a touch on the "Yes" button on the interior light adjustment reception screen 83, it turns off the interior light 41 (ST7). When the interior light 41 is turned off, the processing device 74 displays a game execution screen 84 (see FIG. 5(B)) on the touch panel 73, as shown in FIG. 3. When the processing device 74 detects a touch on the "No" button on the interior light adjustment reception screen 83, it displays the game execution screen 84 on the touch panel 73 without switching the interior light 41 on or off.

When the processing device 74 displays the game execution screen 84, it refers to the memory and acquires the ID of the operation input sensor selected by the user. The processing device 74 then performs an execution process to execute a 100m sprint application that moves the character displayed on the touch panel 73 toward the goal based on the signal detected by the operation input sensor selected by the user (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 74 acquires the signal detected by the first input sensor via the control device 70. The processing device 74 then moves the character displayed on the touch panel 73 based on the signal detected by the first input sensor. In this embodiment, the processing device 74 may be configured to move the character forward in response to the raising and lowering of the knees of the user seated on the seat main body 5 detected by the first input sensor.

When the ID corresponding to the B button is stored in the memory as the ID of the operation input sensor, the processing device 74 moves the character based on the signal detected by the second front input sensor. More specifically, the control device 70 may move the character forward in response to a user's contact (touch) detected by the second front sensor.

When the ID corresponding to the C button is stored in the memory as the ID of the operation input sensor, the processing device 74 moves the character based on the signal detected by the second lateral sensor. More specifically, the control device 70 may move the character forward in response to a user's contact (touch) detected by the second lateral input sensor.

However, the processing unit 74 may change the amount of movement of the character depending on the magnitude of the signal detected by the operation input sensor. When the character reaches the goal, the processing unit 74 displays a result display screen 85 (see FIG. 5(C)) on the touch panel 73, which includes the time required to reach the goal and the calories burned, and then ends the application.

Next, the operation of the seat system 1 configured in this manner will be described. For example, when a user seated on the mid-seat main body 5B starts an application for a 100m sprint game, a participation acceptance screen 80 is displayed on the touch panel 73 of the application execution device 72. When the user touches the "Yes" button, a sensor selection screen 81 is displayed. At this time, the processing device 74 selects a sensor that detects contact with the seating surface 13 on which the user sits from the first sensors 51 and sets it as the first input sensor. Also, the processing device 74 sets a sensor that is provided on the back surface of the seat back 11 of the front seat main body 5A from the second sensors 52 and detects the user's contact with the back surface as the second front input sensor. Also, the processing device 74 sets a sensor that is provided on the door trim 18 provided on the rear door 16 located to the side of the mid-seat main body 5B and detects the user's contact with the surface on the inside of the vehicle as the second lateral input sensor. After that, the processing device 74 displays the positions of the first input sensor, the second front input sensor, and the second lateral input sensor on the sensor selection screen 81 and the buttons corresponding to each sensor on the touch panel 73. This allows the user to select the operation input sensor from among the first input sensor, the second front input sensor, and the second side input sensor.

After that, when the user touches a button displayed on the sensor selection screen 81 to select a sensor, the processing device 74 displays a seat adjustment reception screen 82 on the touch panel 73. When the user touches the "Yes" button displayed on the seat adjustment reception screen 82, the mid-seat body 5B moves as far back as possible. This increases the distance between the front seat body 5A and the mid-seat body 5B, and the mid-seat body 5B on which the user sits is positioned in a position that makes it easy for the seated user to move their legs up and down. At the same time, the seat back 11 of the mid-seat body 5B on which the user sits rises up against the seat cushion 10, and the mid-seat body 5B takes on a shape that makes it easy for the seated user to move their legs up and down. This allows the application execution device 72 to adjust the seat body 5 to a position and shape that allows the user in the vehicle to enjoy the game more. In other words, the position and shape of the seat body 5 are adjusted to suit the use of the application, and an environment in which the user can enjoy the game more can be provided.

Next, the processing device 74 displays an interior light adjustment reception screen 83 on the touch panel 73 of the application execution device 72. When the user touches the "Yes" button on the interior light adjustment reception screen 83, the interior light 41 is turned off. This makes it easier for the user to recognize the screen display on the touch panel 73. This provides the user with an environment in which they can enjoy the game more.

Then, the processing device 74 displays a game execution screen 84 on the touch panel 73. The user moves the character by inputting to the operation input sensor selected by the user. In other words, the operation input sensor selected from the first sensor 51 and the second sensor 52 constitutes the application controller of the application execution device 72. When the character reaches the goal, the processing device 74 ends the 100m sprint game application.

Next, the effects of the seat system 1 configured in this manner will be described. On the sensor selection screen 81, the user can select an operation input sensor that performs input to operate the character from among the first input sensor, the second front input sensor, and the second lateral input sensor. This increases the number of sensors that the user can input from compared to when only the first sensor 51 is provided in the vehicle interior 2. Therefore, for example, a user with a disability can select the second front sensor or the second lateral sensor and enjoy a game. In other words, the seat system 1 can provide an operation input method that is suitable for more users. In addition, it is possible to increase the number of operation means for the game application executed by the application execution device 72. This allows more users to enjoy the game application, and a wider variety of applications can be provided to the users.

A sensor provided on the seat cushion 10 of the seat main body 5 on which the user sits is set as the first input sensor. This allows the first sensor 51 to be provided in a position that makes it easy for the user to input. In addition, the user can operate the game application while seated on the seat main body 5, making it easy to operate the game application.

A sensor provided on the instrument panel 20 located in front of the seat body 5 on which the user sits or on the back of the seat back 11 is set as the second front input sensor. This allows a sensor provided in a position that is easy for the user to input to be set as the second front input sensor.

The sensor provided on the door trim 17, 18 or the rear side trim 19 located to the side of the seat body 5 where the user sits is set as the second lateral input sensor. This allows the sensor provided in a position where the user can easily input to be set as the second lateral input sensor.

In the above embodiment, the game application includes a selection process that allows the user to select at least one sensor from the first sensor 51, the second front sensor, and the second side sensor, and an execution process that moves the character based on a signal from the selected sensor. This prevents the character from moving even if the user unintentionally touches a sensor other than the selected sensor, thereby preventing malfunctions due to input to a sensor other than the selected sensor. In addition, since the user can select the sensor to be used to operate the game application from the first input sensor and the second input sensor, i.e., the operation input sensor, the user can select the sensor suitable for operating the game application for himself or herself.

<<Second embodiment>>
The seat system 101 according to the second embodiment differs from the first embodiment in the configuration of the application execution device 72, and the details of the selection reception process, seat adjustment process, and execution process included in the 100m sprint game application, but is otherwise similar to the first embodiment. Therefore, a description of the other configuration will be omitted.

As shown in FIG. 6, the application execution device 72 according to this embodiment is equipped with a GPS receiver 102, and the processing device 74 of the application execution device 72 is connectable to a server 104 that holds weather information via a network 103 such as the Internet by public line communication.

In the selection reception process, the processing device 74 receives a signal from a satellite via the GPS receiver 102 and acquires the position of the application execution device 72. The processing device 74 then connects to the server 104 that holds weather information via the network 103. The processing device 74 then acquires the predicted outside temperature at the position of the application execution device 72 from the server 104. When the predicted outside temperature is equal to or higher than a predetermined threshold, the processing device 74 selects the first sensor 51 and stores the ID of the first sensor 51, which is the selection result, in memory. At this time, since the outside temperature is equal to or higher than the threshold, the processing device 74 may display a screen on the touch panel 73 notifying the user that the processing device 74 has selected the operation input sensor because the outside temperature is equal to or higher than the threshold. When the predicted outside 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 the "A" to "C" buttons are displayed on the touch panel 73, as in the first embodiment. The processing device 74 then detects touches to each button on the touch panel 73, accepts the user's selection of the operation input sensor, and stores the ID of the operation input sensor in memory.

In the seat adjustment process, the processing device 74 controls the amount of operation of the adjustment mechanism 25 based on information from the server 104. More specifically, when the outside air temperature is equal to or higher than a threshold value in the seat adjustment process, the processing device 74 controls the amount of operation of the tilt actuator 37 so that the seat back 11 is inclined slightly rearward relative to the seat cushion 10, as compared to when the outside air temperature is less than the threshold value, thereby deforming the seat body 5.

When the outside air temperature is equal to or higher than the threshold during the execution process, the processing device 74 moves the character faster in response to an input to the first input sensor than when the outside air temperature is lower than the threshold. In other words, when the outside air temperature is equal to or higher than the threshold during the execution process, the processing device 74 increases the character movement speed in response to an input to the first input sensor.

The operation and effects of the seat system 101 according to the second embodiment will be described. When the outside temperature is predicted to be equal to or higher than the threshold in the selection reception process, for example on a summer day, the first sensor 51 is selected as the operation input sensor by the processing device 74. This allows the amount of exercise performed by the user while playing the game to be reduced compared to when the user inputs to the second front sensor or the second lateral sensor. This prevents the user from losing too much physical strength while playing the game when the predicted outside temperature is equal to or higher than the threshold, for example on a summer day. On the other hand, when the outside temperature is below the threshold, the user himself selects the operation input sensor from among the first input sensor, the second front input sensor, and the second lateral input sensor.

In this way, in the seat system 101 according to the second embodiment, an operation input sensor is selected based on the outside air temperature, which is information related to the user's surrounding environment stored in the server 104. That is, in the seat system 1, a sensor suitable for the user's surrounding environment is selected as the operation input sensor, and the user can operate the game application by inputting information into that operation input sensor. This improves the usability of the seat system 1.

Furthermore, in this embodiment, when the outside temperature is equal to or higher than a threshold, the character's movement speed in response to an input to the first input sensor is increased. This reduces the amount of exercise the user must perform during the game, providing a more suitable environment for the user.

When the outside air temperature is equal to or higher than the threshold, the seat back 11 is tilted slightly backward relative to the seat cushion 10. This makes it easier for a gap to form between the user's back and the seat back 11 when the outside air temperature is equal to or higher than the threshold. This allows the user to enjoy the game in a cooler environment, and the seat body 5 has a shape that is more suitable for the user. In other words, the processing device 74 can control the tilt actuator 37 according to the user's situation based on information from the server 104, providing the user with an environment in which the game can be more enjoyed.

<<Third embodiment>>
The seat system 201 according to the third embodiment differs from the seat system 1 according to the first embodiment in that it includes a speaker 202. In the third embodiment, the content of the game executed in the application execution device 72 differs from that of the first embodiment, and the participation acceptance screen 80, selection acceptance process, and execution process are different. The other configurations of the third embodiment are the same as those of the first embodiment, and therefore description thereof will be omitted.

As shown in FIG. 7, the seat system 201 has a speaker 202A provided on the door trim 17 of the left and right front doors 15, a speaker 202B provided on the door trim 18 of the left and right rear doors 16, and a speaker 202C provided on the left and right rear side trim 19. The speakers 202A, 202B, and 202C are coupled to the outer side of the corresponding trims 17, 18, and 19, and are connected to the control device 70 via a predetermined signal line. Each speaker generates sound toward the inside of the passenger compartment 2 based on a signal from the control device 70. That is, the control device 70 can control the sound output from each speaker 202A, 202B, and 202C. The control device 70 receives a signal from the processing device 74 of the application execution device 72 and outputs a signal to each speaker.

The game application executed by the application execution device 72 allows the user to input to the sensor in time with the music, as shown on the game execution screen 284 (see Figure 8).

In the selection reception process, the processing device 74 displays the first input sensor, the second front input sensor, and the second side input sensor on the sensor selection screen 81, as in the first embodiment, and receives two operation input sensors from the user. The processing device 74 stores the IDs of the two operation input sensors in memory.

In the execution process, the processing device 74 first acquires the seating position of the user holding the application execution device 72, and extracts the speaker 202 closest to the seating position as the output speaker. The processing device 74 then causes the output speaker to output a predetermined piece of music. At this time, the processing device 74 displays a game execution screen 284 (see FIG. 8) corresponding to the music, and simultaneously acquires signals from the two operation input sensors via the control device 70. At this time, the processing device 74 may display input instructions to the user for each of the operation input sensors on the game execution screen 284. Furthermore, the processing device 74 may calculate the degree of coincidence between the music and the timing of the user's input to each of the operation input sensors based on the signals from the two operation input sensors, and display the results on the screen.

The effects of the seat system 201 according to the third embodiment will be described. Since the seat system 201 according to the third embodiment includes the speaker 202, it is possible to configure a game application that performs input to an operation input sensor in accordance with sound. Furthermore, the application execution device 72 can generate sound from the speaker 202 via the control device 70 in a manner suitable for the execution of the game. This allows the application execution device 72 to provide the user with an environment that is more realistic and allows the user to enjoy the game more. In other words, the application execution device 72 can provide the user with an environment suitable for the use of the application execution device 72.

The processing device 74 performs execution processing based on signals from the two operation input sensors. This allows the game application executed by the application execution device 72 to be operated based on signals from multiple operation input sensors. This increases the variety of game applications that can be provided to users.

Although the description of the specific embodiment is now complete, the present invention is not limited to the above embodiment and can be modified and implemented in a wide variety of ways. For example, the first and second embodiments describe an example in which a 100m sprint game application is executed by one application execution device 72, but the present invention is not limited to this aspect. For example, the application execution devices 72 may be configured to be able to wirelessly communicate with each other, and multiple application execution devices 72 may be configured to be able to execute the 100m sprint game application simultaneously.

More specifically, when two users are seated in the mid-seat main body 5B, the 100m sprint game may be configured so that two people can enjoy the game at the same time. In this case, when a game application is started in one application execution device 72, the application execution device 72 may be configured to notify the other application execution devices 72 in the vehicle. Also, as shown in FIG. 9, the application execution device 72 may be configured to display characters corresponding to each user on the touch panel 73 and move the characters forward in response to input to each operation input sensor. This allows each user to select the operation input sensor that is most suitable for them, so that multiple people, including physically disabled users who have difficulty inputting information into the seating sensors, can enjoy the game at the same time.

In the above embodiment, the seat system 1, 101, 201 mounted on the vehicle S has been described, but is not limited to this embodiment.

The support base 309 accommodates an adjustment mechanism 325 that moves the support base 309 back and forth and left and right relative to the floor 303 and rotates it around a vertical axis, and a control device 370 that controls the drive of the adjustment mechanism 325. The adjustment mechanism 325 includes a plurality of wheels 325A and a motor 325B that controls the drive of each of the wheels 325A. When the game application is executed, the application execution device 372 obtains the position of the seat body 305 by wirelessly communicating with the control device 370. The application execution device 372 then operates the adjustment mechanism 325 via the control device 370 to move the seat body 305 forward, backward, left, and right, and further rotates the seat body 305 around a vertical axis, thereby moving the seat body 305 to a position suitable for playing a game.

In addition, a first sensor 351 that detects a user's contact with the seating surface 313 may be provided inside the seat body 305, more specifically inside the seat cushion 310, and a second sensor 352 that detects a user's contact may be provided on the desk 306.

In the second embodiment described above, the processing device 74 is configured to obtain the predicted air temperature from the server 104, but this is not limited to the above. For example, the processing device 74 may be configured to obtain the predicted weather, humidity, or precipitation from the server 104, and control the amount of operation of the adjustment mechanism 25 based on the obtained information.

In the third embodiment, the application execution device 72, 372 executes a game application based on signals from two operation input sensors, but this is not limited to the above embodiment. The application execution device 72, 372 may execute a game application based on signals from three or more sensors included in the first sensor 51, 351 or the second sensor 52, 352.

In the above embodiment, the adjustment mechanism 25 includes the slide mechanism 26, the reclining mechanism 27, the rotation mechanism 28 that rotates the seat cushion 10 around a vertical axis relative to the floor 3, and the height adjustment mechanism 29, but the adjustment mechanism 25 is not limited to these. The adjustment mechanism 24 may include, for example, a floor rotation mechanism that rotates at least a part of the floor 3. In this case, the floor 3 may include a plate-shaped fixed part that is fixed to a frame that constitutes the vehicle body and has a circular opening, and a disk-shaped movable part that is housed in the opening and is flush with the fixed part. The movable part is supported rotatably with an axis that is vertical to the frame that constitutes the vehicle body, and the floor rotation mechanism may include a motor that rotates the movable part relative to the frame.
