[Technical Field]

[0001] The present invention relates to a seating system including a seat having a sensor. [Background technology]

[0002] BACKGROUND ART Conventionally, a vehicle seat is known in which a plurality of pressure sensors are arranged on the seat to detect the seating posture of an occupant (Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2017-65504 Summary of the Invention [Problem to be solved by the invention]

[0004] However, conventional vehicle seats only evaluate and indicate the driver's seating posture, which is problematic in that they cannot be used very effectively.

[0005] Therefore, an object of the present invention is to improve the entertainment value of seats in order to propose new value for seats. [Means for solving the problem]

[0006] In order to solve the above problem, the seat system according to the present invention includes a seat, a seat actuation device that moves the entire seat, and a control unit. The seat has a seat body and a sensor that acquires user information, which is information about a user sitting in the seat body. The control unit is capable of executing an application program that operates based on the user information acquired by the sensor, and while the application program is running, the control unit controls the seat actuation device based on the user information acquired by the sensor to move the entire seat.

[0007] According to this configuration, while an application program that operates based on user information is being executed, the entire seat is moved based on the user information. Therefore, for example, when an application program that provides a game is executed, the entire seat can be moved in accordance with the game, thereby improving the entertainment value of the seat.

[0008] The seat operating device may also include a rail that movably supports the seat, and a motor that moves the seat on the rail.

[0009] According to this configuration, the seat can be moved along the rails while the application program is being executed.

[0010] The application program may be a program for moving a character on a screen, and the control unit may change the moving speed of the character and the moving speed of the sheet in accordance with the user information.

[0011] According to this configuration, the moving speed of the character on the screen and the moving speed of the seat are changed in accordance with the user information, which further improves the entertainment value of the seat.

[0012] The sensor may also include a first sensor and a second sensor arranged on one side of the movement direction of the seat relative to the first sensor, and the control unit may determine whether the user has leaned to one side or the other of the movement direction based on information from the first sensor and the second sensor, and if it determines that the user has leaned to one side of the movement direction, move the seat to one side of the movement direction, and if it determines that the user has leaned to the other side of the movement direction, move the seat to the other side of the movement direction.

[0013] With this configuration, when the user leans their body on the seat, the seat can be moved in the direction in which the user leans their body.

[0014] The seat operating device may include a base that rotatably supports the seat, and a motor that rotates the seat.

[0015] According to this configuration, the seat can be rotated while an application program is being executed.

[0016] The sensor may also have a left sensor arranged on the left side of the seat body and a right sensor arranged on the right side of the seat body, and the control unit may determine whether the user has leaned to the left or right based on information from the left sensor and the right sensor, and if it determines that the user has leaned to the left, rotate the seat counterclockwise, or if it determines that the user has leaned to the right, rotate the seat clockwise.

[0017] According to this configuration, the user can rotate the seat by leaning their body left or right on the seat. [Effects of the Invention]

[0018] According to the present invention, the entertainment value of the seat can be improved.

[0019] Furthermore, according to the present invention, the seat operating device includes a rail and a motor, so that the seat can be moved along the rail while an application program is being executed.

[0020] Furthermore, according to the present invention, the control unit can change the moving speed of the character on the screen and the moving speed of the seat in accordance with the user information, thereby further improving the entertainment value of the seat.

[0021] Furthermore, according to the present invention, the control unit is configured to determine the inclination of the user's body based on information from a first sensor and a second sensor arranged at different positions in the movement direction, and to move the seat according to the direction of the inclination, thereby making it possible to move the seat according to the user's inclination on the seat.

[0022] Furthermore, according to the present invention, the seat operating device includes a motor that rotates the seat, so that the seat can be rotated while an application program is being executed.

[0023] Furthermore, according to the present invention, the inclination of the user's body is determined based on information from the left and right sensors, and the seat is rotated according to the direction of the inclination, thereby allowing the seat to be rotated according to the user's inclination on the seat.

DETAILED DESCRIPTION OF THE INVENTION

[0025] A first embodiment of the present invention will be described below with reference to the drawings. As shown in Figure 1, the seat system 1 is installed in a vehicle 50 with three rows of seats. The seat system 1 includes a seat 10, a seat actuation device 20, and a control unit 30. In this specification, front, rear, left, right, and top and bottom are determined based on the position of an occupant sitting in the seat 10.

[0026] The seat 10 is a seat in the third row of three rows of seats. The seats 10 are provided on the left and right sides of the vehicle interior (see FIG. 3). In this embodiment, the first row seat 41 and the second row seat 42 do not have sensors and do not constitute the seat system 1.

[0027] The seat actuation device 20 is a device that moves the entire seat 10 in the front-to-rear direction. As shown in FIG. 3(a), one seat actuation device 20 is provided for each of the left and right seats 10. In the following explanation, the left seat actuation device 20 will be explained as a representative, and an explanation of the right seat will be omitted.

[0028] The seat operating device 20 includes a rail 21 and a motor 22. The rails 21 extend in the front-rear direction from the first row to the third row of the three-row seat arrangement, with one rail 21 provided on each side of each seat 41, 42, 10. The rails 21 support the three seats 41, 42, 10 so that they can move in the front-rear direction. More specifically, as shown in FIG. 1 , each of the three seats 41, 42, 10 is supported by a slider 60 that is movably supported on the rail 21.

[0029] The motor 22 is a motor for moving the rearmost seat 10 on the rails 21, and is provided on the rearmost slider 60. The rearmost slider 60 has wheels (not shown) to which the driving force of the motor 22 is transmitted, and the rearmost slider 60 moves on the rails 21 as the wheels rotate.

[0030] As shown in FIG. 2, the seat 10 has a seat body 10A and pressure sensors PS1 to PS6 as an example of sensors.

[0031] The seat body 10A is a member having a seating surface that supports the user. The seat body 10A includes a seat cushion 11, a seat back 12, and a headrest 13. The seat cushion 11, the seat back 12, and the headrest 13 each have a frame that forms a skeleton, a pad that covers the frame, and a cover that covers the pad. The upper surface of the seat cushion 11 forms the seating surface. The front surfaces of the seat back 12 and the headrest 13 each form the seating surface.

[0032] The pressure sensors PS1 to PS3 are sensors that acquire measurements of pressure (hereinafter also referred to as "pressure values") from a user sitting on the seat main body 10A. The pressure values ​​from the user correspond to user information, which is information about the user sitting on the seat main body 10A. The pressure sensors PS1 to PS3 are provided between the surface and pad of the seat cushion 11, and the pressure sensors PS4 to PS6 are provided between the surface and pad of the seat back 12. Each of the pressure sensors PS1 to PS6 is provided in pairs symmetrically on the left and right sides of the center of the seat 10.

[0033] The pressure sensors PS1 and PS2 are disposed at positions on the seat cushion 11 corresponding to the user's buttocks. Specifically, the pressure sensor PS1 is disposed at a position corresponding to the lowest part of the user's ischial bones where the greatest load from the user is applied, and the pressure sensor PS2 is disposed in a position slightly in front of the pressure sensor PS1. The pressure sensors PS1 and PS2 acquire pressure values ​​from the user's buttocks. The pressure sensor PS3 is disposed at a position far forward from the pressure sensors PS1 and PS2, specifically at a position corresponding to the user's thighs. The pressure sensor PS3 acquires pressure values ​​from the user's thighs.

[0034] The pressure sensors PS4 and PS5 are disposed under the seat back 12. More specifically, the pressure sensor PS4 is disposed at a position corresponding to the back of the user's waist, and the pressure sensor PS5 is disposed slightly above the pressure sensor PS4. The pressure sensors PS4 and PS5 acquire pressure values ​​from the user's waist. The pressure sensor PS6 is disposed at a position far above the pressure sensors PS4 and PS5, specifically at a position corresponding to the upper part of the user's back. The pressure sensor PS6 acquires pressure values ​​from the position corresponding to the upper part of the user's back.

[0035] The pressure sensors PS1 to PS6 are elements whose electrical resistance changes depending on the external pressure, and the greater the pressure value, the higher or lower the voltage of the detection signal. The pressure sensors PS1 to PS6 output the pressure values ​​to the control unit 30 (more specifically, the seat control unit 31, which will be described later).

[0036] The control unit 30 includes a seat control unit 31 and a smartphone 32 .

[0037] The seat control unit 31 is capable of communicating with the smartphone 32. The seat control unit 31 is capable of acquiring pressure values ​​from the pressure sensors PS1 to PS6 of the left and right seats 10, and is capable of transmitting the acquired pressure values ​​to the smartphone 32. The seat control unit 31 also has a function of moving the entire seat 10 by controlling the motor 22 based on information transmitted from the smartphone 32. Control of the motor 22 will be described later.

[0038] The smartphone 32 has a function to execute a seat application. The seat application is an application, among various application programs (hereinafter also referred to as "applications") executed by the smartphone 32, that operates based on pressure values ​​acquired from the pressure sensors PS1 to PS6 via the seat control unit 31. The seat application is, for example, a game that uses the seat 10 as a controller. An example of the game is a 100m sprint game.

[0039] The 100m sprint game is a game in which a user sitting on the seat 10 moves both legs up and down alternately to make a character displayed on the screen DS of the smartphone 32 run (move). The smartphone 32 progresses the game by determining whether the user is raising and lowering their legs based on pressure values ​​from the left and right pressure sensors PS3, for example.

[0040] When the smartphone 32 starts executing the seat application, it makes an inquiry to the seat control unit 31 to acquire pressure values ​​from the pressure sensors PS1 to PS6. When the seat control unit 31 receives the inquiry from the smartphone 32, it acquires pressure values ​​from the pressure sensors PS1 to PS6 and transmits the acquired pressure values ​​to the smartphone 32.

[0041] Furthermore, the smartphone 32 has a function of setting, based on the pressure value, the movement speed of the character and the seat 10 while the seat app is running. For example, the movement speed of the character and the seat 10 can be set to a faster speed as the number of times the user raises and lowers their legs per unit time increases.

[0042] When the smartphone 32 sets the movement speed of the seat 10, it transmits the set movement speed of the seat 10 to the seat control unit 31. When the seat control unit 31 receives the movement speed of the seat 10, it sets the rotation speed of the motor 22 based on the movement speed of the seat 10 and drives the motor 22 at the set rotation speed. The rotation speed of the motor 22 is set to a larger value as the movement speed of the seat 10 increases.

[0043] In this embodiment, the user can select whether or not the seat application and the seat 10 are linked. When the link between the seat application and the seat 10 is permitted, the seat control unit 31 rotates the motor 22 at the rotation speed set as described above. When the link between the seat application and the seat 10 is not permitted, the seat control unit 31 does not rotate the motor 22.

[0044] Next, the operations of the smartphone 32 and the seat control unit 31 will be described in detail. When the seat application is started, the smartphone 32 executes the process shown in FIG.

[0045] In the process of FIG. 4, the smartphone 32 first displays on the screen DS an image for selecting whether to link the sheet application and the sheet 10 (S1). The image for selecting whether to link the sheet application and the sheet 10 is, for example, the image shown in FIG. 7(a). This image includes an image of text such as "Do you want to move the sheet in linkage with the 100m game?", a button image B1 with the word "Yes" written on it for selecting the linkage, and a button image B2 with the word "No" written on it for not selecting the linkage.

[0046] 4, after step S1, the smartphone 32 determines whether or not there is a request to link the seat 10 to the seat app (S2). In detail, in step S2, if the smartphone 32 determines that the button image B1 has been selected, it determines that there is a request, and if the smartphone 32 determines that the button image B2 has been selected, it determines that there is no request.

[0047] If it is determined in step S2 that a request has been made (Yes), the smartphone 32 notifies the user of an instruction to arrange the seats 41, 42, and 10 in the game positions (S3). The instruction to arrange the seats 41, 42, and 10 in the game positions can be given by, for example, displaying an image shown in FIG. 7(b) on the screen DS. This image includes an image of text such as "Please arrange the seats in the first and second rows at the front and the seats in the third row at the rear," an image of a diagram showing the seat arrangement, and a button image B3 with the word "OK" written on it for proceeding with the process after the user has arranged the seats in the game positions.

[0048] 4, after step S3, the smartphone 32 transmits a linkage permission signal to the seat control unit 31 to link the seat 10 with the seat application (S4). In detail, after step S3, the smartphone 32 determines whether or not the button image B3 is selected, and if the button image B3 is selected, executes the process of step S4.

[0049] After step S4, or if step S2 returns No, the smartphone 32 displays a start image of the 100m sprint game on the screen DS (S5). The start image displays a start button for starting the 100m sprint game, an end button for ending the seat app, and a number setting button for setting the number of players participating in the game.

[0050] After step S5, the smartphone 32 determines whether or not the start button displayed on the screen DS has been selected (S6). If it is determined in step S6 that the start button has been selected (Yes), the smartphone 32 determines whether or not a flag F indicating whether calibration in the 100m sprint game has already been performed in the past is 0 (S7).

[0051] Here, calibration refers to a process of determining a standard value for pressure in accordance with the weight of the user in the 100-meter sprint game. The smartphone 32 determines whether the user is raising or lowering their legs by comparing the pressure values ​​acquired by the pressure sensors PS1 to PS6 with the standard value. When there are two players, the smartphone 32 performs calibration for each player sitting on each seat 10.

[0052] If it is determined in step S7 that F=0 (Yes), that is, if calibration has never been performed in the past, the smartphone 32 performs calibration (S8). After step S8, the smartphone 32 sets flag F to 1 (S9) and executes the 100m sprint game (S10). The processing of the 100m sprint game will be described in detail later.

[0053] If it is determined in step S7 that F is not 0 (No), that is, if calibration has been performed in the past, the smartphone 32 starts the 100m sprint game (S10) without performing calibration (S8).

[0054] After step S10, or if it is determined No in step S6, the smartphone 32 displays a start image and determines whether or not the end button displayed on the screen DS has been selected (S11). If it is determined in step S11 that the end button has not been selected (No), the smartphone 32 returns to the processing of step S5. If it is determined in step S11 that the end button has been selected (Yes), the smartphone 32 ends this processing.

[0055] 5, when the 100m sprint game starts, the smartphone 32 first acquires pressure values ​​from the pressure sensors PS1 to PS6 of the seat 10 (S31). After step S31, the smartphone 32 calculates the number of leg lifts per unit time based on the pressure values ​​(S32).

[0056] After step S32, the smartphone 32 sets the movement speed of the character and the seat 10 according to the number of times the leg is raised per unit time (S33). More specifically, in step S33, the smartphone 32 sets the movement speed of the character and the seat 10 to a larger value as the number of times the leg is raised per unit time increases. After setting the movement speed of the character, the smartphone 32 moves the character on the screen DS at the set movement speed.

[0057] The movement speed of the seat 10 may have an upper limit set so that the user sitting in the seat 10 does not interfere with the second-row seat 42. The upper limit can be determined by experiment, simulation, or the like. In this case, if the movement speed of the seat 10 set based on the number of leg lifts per unit time is greater than the upper limit, the smartphone 32 sets the upper limit as the "movement speed of the seat 10."

[0058] After step S33, the smartphone 32 transmits the set movement speed of the seat 10 to the seat control unit 31 (S34). After step S34, the smartphone 32 determines whether or not the character on the screen DS has reached the goal (S35). Note that if there are two players, the smartphone 32 performs the processes of steps S31 to S34 for each of the left and right seats 10, and determines in step S35 whether or not either of the two characters has reached the goal.

[0059] If it is determined in step S35 that the goal has not been reached (No), the smartphone 32 returns to the processing of step S31. If it is determined in step S35 that the goal has been reached (Yes), the smartphone 32 transmits an end signal to the seat control unit 31 (S36). After step S36, the smartphone 32 displays the result of the game on the screen DS and ends this processing.

[0060] The seat control unit 31 repeatedly executes the process shown in FIG. 6, the seat control unit 31 first determines whether or not an interlocking permission signal has been acquired from the smartphone 32 (S51). If it is determined in step S51 that an interlocking permission signal has not been acquired (No), the seat control unit 31 ends this process.

[0061] If it is determined in step S51 that the interlock permission signal has been acquired (Yes), the seat control unit 31 acquires the movement speed of the seat 10 from the smartphone 32 (S52). After step S52, the seat control unit 31 sets the rotation speed of the motor 22 according to the movement speed of the seat 10 (S53).

[0062] After step S53, the seat control section 31 rotates the motor 22 at the set rotation speed (S54). After step S54, the seat control section 31 determines whether or not an end signal has been received from the smartphone 32 (S55).

[0063] If it is determined in step S55 that the end signal has not been acquired (No), the seat control unit 31 returns to the process of step S52. If it is determined in step S55 that the end signal has been acquired (Yes), the seat control unit 31 stops the motor 22 (S56) and ends this process.

[0064] If there are two players, the seat control unit 31 performs the processes of steps S52 to S54 and S56 for each of the left and right seats 10. In step S56, the seat control unit 31 may reversely rotate the motor 22 to return the seat 10 to the rearmost position, which is the initial position, and then stop the motor 22.

[0065] Next, an example of the operation of the smartphone 32 and the seat control unit 31 will be described. When the first user U1 shown in Fig. 8(a) starts the sheet application, the smartphone 32 displays the image shown in Fig. 7(a) on the screen DS. When the first user U1 selects the button image B1, the smartphone 32 displays the image shown in Fig. 7(b) on the screen DS.

[0066] The first user U1 follows the instructions of the letters and figures displayed on the screen DS to place the sheets 41, 42, and 10 in the game positions as shown in Fig. 3(b). When the first user U1 selects the button image B3, a start image (not shown) is displayed on the screen DS.

[0067] When the first user U1 sets the number of players to two in the start image and starts the 100m sprint game, as shown in Figures 8(a) and 8(b), the smartphone 32 sets the movement speed of the first character CH1 and the movement speed of the left seat 10 according to the number of times the first user U1 sitting on the left seat 10 lifts his leg. The smartphone 32 also sets the movement speed of the second character CH2 and the movement speed of the right seat 10 according to the number of times the second user U2 sitting on the right seat 10 lifts his leg.

[0068] If the second user U2 raises his / her leg more frequently than the first user U1, the smartphone 32 moves the second character CH2 forward on the screen DS at a faster moving speed than the first character CH1. If the second user U2 raises his / her leg more frequently than the first user U1, the seat control unit 31 moves the right seat 10 forward at a faster moving speed than the left seat 10.

[0069] Thereafter, the smartphone 32 similarly changes the movement speeds of the characters CH1 and CH2 in accordance with changes in the number of times the users U1 and U2 lift their legs. The seat control unit 31 also changes the movement speed of the seats 10 in accordance with changes in the number of times the users U1 and U2 lift their legs. When either the character CH1 or CH2 reaches the goal on the screen DS, the smartphone 32 displays the results of the 100-meter sprint game on the screen DS and ends the game. The seat control unit 31 also stops the movement of each seat 10.

[0070] When the number of players is set to one, the smartphone 32 displays only one character on the screen DS and moves only one character. When the number of players is set to one, the seat control unit 31 moves only one seat 10 and does not move the other seat 10.

[0071] The correspondence between the characters and the seats 10 may be selectable by the user, for example, when setting the number of players. For example, if a first user U1 sits in the right seat 10 and a second user U2 sits in the left seat 10, the identification number of the right seat 10 may be associated with the first character CH1, and the identification number of the left seat 10 may be associated with the second character CH2.

[0072] As described above, the following effects can be obtained in this embodiment. During execution of a seat application that operates based on a pressure value, the entire seat 10 is moved based on the pressure value, so that when a 100m sprint game is executed, the entire seat 10 can be moved in accordance with the game, improving the entertainment value of the seat 10.

[0073] The seat operating device 20 includes a rail 21 for movably supporting the seat 10 and a motor 22 for moving the seat 10 on the rail 21, so that the seat 10 can be moved along the rail 21 while the 100m running game is being played.

[0074] The moving speed of the character on the screen DS and the moving speed of the seat 10 are changed according to the pressure value that changes with the leg lifting action of the user, so that the entertainment value of the seat 10 can be improved.

[0075] The present invention is not limited to the first embodiment, and can be used in various forms as exemplified below. In the following description, members and processes having substantially the same structure as those in the first embodiment are denoted by the same reference numerals, and their description will be omitted.

[0076] 9, a seat operating device 70 according to the second embodiment has a pair of front and rear rails 71 extending left and right, and a motor 72 for moving the seat 10 left and right on the rails 71. In the second embodiment, a left pressure sensor PS2 is exemplified as the first sensor, and a right pressure sensor PS2 is exemplified as the second sensor arranged on one side of the first sensor in the movement direction of the seat 10.

[0077] The smartphone 32 has a function of determining whether the user has leaned to the right or left based on the pressure values ​​from the left and right pressure sensors PS2. If the smartphone 32 determines that the user has leaned to the right, it causes the seat control unit 31 to move the seat 10 to the right. If the smartphone 32 determines that the user has leaned to the left, it causes the seat control unit 31 to move the seat 10 to the left.

[0078] In the second embodiment, a shooting game is exemplified as a seat application in which a user moves a fighter plane, which is an object of operation, left and right and fires bullets from the fighter plane to defeat enemies. The smartphone 32 executes the process of FIG. 4 from when the seat application is launched until when it is terminated. In the second embodiment, the smartphone 32 executes the shooting game instead of the 100-meter sprint game in step S10 of the process of FIG. 4.

[0079] 10, in a shooting game, the smartphone 32 acquires pressure values ​​from the left and right pressure sensors PS2 (S31), and then determines whether the user has leaned to the left based on the pressure values ​​(S71). Specifically, in step S71, the smartphone 32 determines, for example, whether the pressure value of the left pressure sensor PS2 is greater than the pressure value of the right pressure sensor PS2 by a predetermined value or more.

[0080] If it is determined in step S71 that the user has leaned to the left (Yes), the smartphone 32 moves the operation target on the screen DS to the left (S72). After step S72, the smartphone 32 transmits a leftward movement signal to the seat control unit 31 to move the seat 10 to the left (S73).

[0081] If it is determined in step S71 that the user is not leaning to the left (No), the smartphone 32 determines whether or not the user is leaning to the right based on the pressure value (S74). Specifically, in step S74, the smartphone 32 determines, for example, whether or not the pressure value of the right pressure sensor PS2 is greater than the pressure value of the left pressure sensor PS2 by a predetermined value or more.

[0082] If it is determined in step S74 that the seat 10 has tilted to the right (Yes), the smartphone 32 moves the operation target on the screen DS to the right (S75). After step S75, the smartphone 32 transmits a right movement signal to the seat control unit 31 to move the seat 10 to the right (S76). Note that if the difference between the left and right pressure values ​​is less than a predetermined value, the smartphone 32 does not transmit either the left movement signal or the right movement signal to the seat control unit 31 (step S74: No).

[0083] After step S73 or step S76, or if the result of the determination in step S74 is No, the smartphone 32 determines whether the game has ended (S77). If the result of the determination in step S77 is that the game has not ended (No), the smartphone 32 returns to the processing of step S31. If the result of the determination in step S77 is that the game has ended (Yes), the smartphone 32 performs the processing of steps S36 and S37 similar to those in the first embodiment, and ends this processing.

[0084] Note that the operation of firing bullets from the fighter jet in a shooting game may be performed in any manner. For example, bullets may be fired automatically from the fighter jet without any user operation, or bullets may be fired from the fighter jet by the user pressing a pressure sensor located on the seat back 12.

[0085] In the second embodiment, the seat control unit 31 repeatedly executes the process of Fig. 11. In the process of Fig. 11, the seat control unit 31 first executes the process of step S51 similar to that of the first embodiment. If the result of step S51 is No, the seat control unit 31 ends this process, and if the result of step S51 is Yes, the seat control unit 31 acquires a leftward movement signal or a rightward movement signal from the smartphone 32 (S91).

[0086] After step S91, the seat control unit 31 sets the rotation direction of the motor 72 in accordance with the left movement signal or the right movement signal (S92). Specifically, if the seat control unit 31 acquires a left movement signal in step S91, it sets the rotation direction of the motor 72 to a first rotation direction, which is a rotation direction for moving the seat 10 to the left. Furthermore, if the seat control unit 31 acquires a right movement signal in step S91, it sets the rotation direction of the motor 72 to a direction opposite to the first rotation direction, specifically a second rotation direction, which is a rotation direction for moving the seat 10 to the right. Furthermore, if the seat control unit 31 does not acquire either a left movement signal or a right movement signal in step S91, it does not set the rotation direction of the motor 72 and keeps the motor 72 stopped.

[0087] After step S92, if the rotation direction of the motor 72 is set in step S92, the seat control section 31 rotates the motor 72 in the set rotation direction (S93). Note that if the rotation direction of the motor 72 is not set in step S92, the seat control section 31 does not rotate the motor 72 in step S93.

[0088] After step S93, the seat control section 31 determines whether or not an end signal has been received from the smartphone 32 (S94). If it is determined in step S94 that an end signal has not been received (No), the seat control section 31 returns to the process of step S91.

[0089] If it is determined in step S94 that the end signal has been acquired (Yes), the seat control unit 31 stops the motor 72 (S56) and ends this process. As described above, according to the second embodiment, by the user leaning their body left or right on the seat 10, the operation target and the seat 10 can be moved in the direction of the leaning body.

[0090] The control method for moving the seat 10 in the direction of the user's body inclination can also be applied to the structure of the first embodiment. In this case, the first sensor and the second sensor may be sensors disposed at different positions in the front-rear direction, and the control unit may move the seat 10 in the front-rear direction in accordance with the user's front-rear inclination.

[0091] 12, a seat operating device 80 according to the third embodiment includes a base 81 that supports the seat 10 so that the seat 10 is rotatable about a vertical axis, and a motor 82 that rotates the seat 10. In the third embodiment, the left pressure sensor PS2 is exemplified as the left sensor, and the right pressure sensor PS2 is exemplified as the right sensor.

[0092] The smartphone 32 has a function of determining whether the user has leaned to the right or left based on the pressure values ​​from the left and right pressure sensors PS2. If the smartphone 32 determines that the user has leaned to the left, it causes the seat control unit 31 to rotate the seat 10 counterclockwise. If the smartphone 32 determines that the user has leaned to the right, it causes the seat control unit 31 to rotate the seat 10 clockwise.

[0093] In the third embodiment, a shooting game is exemplified as a seat application in which a user defeats enemies by rotating a rotating turret, which is an object to be operated by the user, left and right and firing bullets from the rotating turret. The smartphone 32 executes the process of FIG. 4 from when the seat application is launched until it is terminated. In the third embodiment, the smartphone 32 executes the shooting game instead of the 100-meter sprint game in step S10 of the process of FIG. 4.

[0094] In the third embodiment, the smartphone 32 performs substantially the same processing as the processing in Fig. 10. Specifically, the smartphone 32 rotates the operation target counterclockwise in the processing of step S72, and transmits a counterclockwise rotation signal to the seat control unit 31 in the processing of step S73. Furthermore, the smartphone 32 rotates the operation target clockwise in the processing of step S75, and transmits a clockwise rotation signal to the seat control unit 31 in the processing of step S76. The other processing in the processing in Fig. 10 is similar, and therefore description thereof will be omitted.

[0095] In the third embodiment, the seat control unit 31 performs substantially the same processing as that in Fig. 11. Specifically, the seat control unit 31 acquires a left rotation signal or a right rotation signal in step S91, and sets the rotation direction of the motor 82 in accordance with the left rotation signal or the right rotation signal in step S92. Other processing in the processing in Fig. 11 is similar, and therefore description thereof will be omitted.

[0096] As described above, according to the third embodiment, the user can rotate the operation object and the seat 10 by leaning his or her body left or right on the seat 10.

[0097] In the above embodiment, the control unit is configured by a seat control unit and a smartphone, but the present invention is not limited to this. For example, the control unit may be configured only by a vehicle-side control unit provided in the vehicle. In this case, the vehicle-side control unit may acquire information from a seat sensor and execute a seat app on the screen of the car navigation system.

[0098] The control unit may be configured to stop the movement of the seat when the user stands up from the seat while the seat application is running. In this case, the determination of whether the user has stood up from the seat may be made, for example, by determining whether the pressure values ​​of all the pressure sensors have become 0.

[0099] The control unit may be configured to stop the movement of the seat when the user presses a seat stop button displayed on the screen while the seat application is running.The control unit may be configured to stop the movement of the seat when the control unit receives a seat stop command from the user's voice while the seat application is running.

[0100] The control unit may be configured to stop the movement of the seat when an abnormal load equal to or greater than a predetermined value is applied to a motor for moving the seat while the seat application is running.The control unit may also be configured to stop the movement of the seat when an abnormality such as a disconnection occurs in the seat system.

[0101] The control unit may also be configured not to move the seat while the seat application is running if the charge level of the vehicle battery that supplies power to the motor that moves the seat is equal to or less than a predetermined value.

[0102] The way in which the seat is moved is not limited to the above embodiment. For example, the seat may be configured so that a first user and a second user play a competitive game (such as dice or rock-paper-scissors) on the smartphone screen, and the seat of the winner moves forward, and the seat of the loser moves backward. Also, for example, the seat may be configured so that when the user presses their back against the seat back, the seat moves backward.

[0103] The first and second row seats may be provided with motors, and these seats may be included in the seat system. In this case, when the 100m sprint game is started, the control unit may be configured to drive the motors of the first and second row seats to move the first and second row seats to their respective forward-most positions.

[0104] The rail 21 in the first embodiment may be a normal slide rail instead of a long rail extending from the first row to the third row.

[0105] The speed at which the seat moves may be constant. For example, in the case of a 100m sprint game, the seat may be configured to move forward at a constant speed only when the character's moving speed is equal to or greater than a predetermined value.

[0106] In the above embodiment, the operation target is moved relative to the background of the screen, but the present invention is not limited to this. For example, the operation target may be fixed at a predetermined position on the screen and the background may be moved, thereby moving the operation target on the screen relative to the background.

[0107] The mobile terminal is not limited to a smartphone, but may be, for example, a tablet.

[0108] The seat app may be a game such as a dance game or a car race, or may be any app that uses the seat as a controller to operate the seat. Specifically, it may simply be an app for operating the seat. In this case, the object to be operated may not be displayed on the screen, and only the seat may be moved in response to the user's movements on the seat. For example, the screen may display only the operation instructions for the seat, and the seat may be moved by the user moving their body on the seat while viewing the operation instructions.

[0109] In the above embodiment, a pressure sensor is used as an example of the sensor, but the present invention is not limited to this. The sensor may be, for example, an optical sensor, a capacitance sensor, a temperature sensor, a humidity sensor, a radio wave sensor, or a sound sensor. The user information is not limited to pressure values ​​and may be any information. For example, if a radio wave sensor is used as the sensor, information regarding the heart rate, which is a physical condition of the user, may be obtained by the radio wave sensor.

[0110] The sensors may also be provided on the left and right sides of the seat cushion or seat back (portions protruding from the seat surface), the headrest, the armrest, or parts around the seat (instrument panel, door, floor), etc.

[0111] The elements described in the above-described embodiment and modified examples may be implemented in any combination. [Explanation of symbols]
