[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 of the present invention comprises a seat body on which a user can sit, a plurality of sensors provided on the seat body to which information is input by the user, and a control unit that acquires information from the sensors. The control unit changes the output based on the degree of coincidence between the timings of inputting information to the at least two sensors.

[0007] With this configuration, the output is changed based on the degree of coincidence between the timing of information input to the two sensors, so that various application programs, such as games, can be provided to the user, thereby improving the entertainment value of the seat.

[0008] The control unit may also execute an application program based on the information from the sensor, and the higher the degree of coincidence of the input timing, the higher an evaluation value of the application program.

[0009] The application program may be a program for moving a character on a screen, and the control unit may increase the speed of the character as the degree of coincidence of the input timing increases.

[0010] According to this configuration, it is possible to provide the user with a game such as a three-legged race, for example.

[0011] The sensors may be pressure sensors, and the control unit may determine that the smaller the difference between the pressure values ​​simultaneously acquired by the two pressure sensors, the higher the degree of coincidence of the input timings.

[0012] The control unit may also calculate the sum of the differences in pressure values ​​of the two pressure sensors over a predetermined period going back from the present time, and determine that the smaller the sum is, the higher the degree of coincidence of the input timings.

[0013] The control unit may also notify the timing of inputting information to the sensor.

[0014] The seat body may be capable of accommodating two or more users, the plurality of sensors may include a first sensor to which information is input from a first user and a second sensor to which information is input from a second user, and the control unit may change the output based on the degree of coincidence between the timing of the first user inputting information to the first sensor and the timing of the second user inputting information to the second sensor.

[0015] The seat body may also include a first seat body on which a first user can sit and a second seat body separate from the first seat body on which a second user can sit, the first seat body having a first sensor to which information is input from the first user, and the second seat body having a second sensor to which information is input from the second user, and the control unit may change the output based on the degree of coincidence between the timing of the first user inputting information to the first sensor and the timing of the second user inputting information to the second sensor. [Effects of the Invention]

[0016] According to the present invention, the entertainment value of the seat can be improved.

[0017] Furthermore, the control unit can provide the user with a game such as a three-legged race, for example, by increasing the speed of the character moving on the screen as the degree of coincidence in the timing of input of information to the sensors increases.

DETAILED DESCRIPTION OF THE INVENTION

[0019] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. 1, the seat system 1 includes a seat 10 and a control unit 20. In the following description, front, back, left, right, up and down are based on the user sitting in the seat 10.

[0020] The seat 10 is a bench-like seat and includes a seat body 11 whose seat surface is longer in the left-right direction than in the front-to-back direction, and a plurality of pressure sensors P as an example of sensors. The seat body 11 can accommodate two or more users. The seat body 11 includes a seat cushion 11A and a seat back 11B.

[0021] The pressure sensor P is a sensor that acquires pressure, which is information for identifying the physical state (posture and movement of the user's body) of the user sitting on the seat main body 11. The pressure sensor P is provided between the surface and pad of the seat cushion 11A.

[0022] The plurality of pressure sensors P includes a plurality of first sensors P1 to which pressure information is input from a first user, and a plurality of second sensors P2 to which pressure information is input from a second user. In this embodiment, the number of the first sensors P1 and the number of the second sensors P2 are each set to 12.

[0023] The plurality of first sensors P1 are arranged in a first range R1, which is a range to the right of the center in the left-right direction of the seat cushion 11A. The plurality of first sensors P1 are arranged so that two rows of six first sensors P1 arranged at intervals in the left-right direction are arranged at intervals in the front-rear direction. The six rear first sensors P1 are arranged at positions corresponding to the buttocks of the seated occupant. The six front first sensors P1 are arranged at positions corresponding to the thighs of the seated occupant.

[0024] The second sensors P2 are arranged in a second range R2, which is a range to the left of the center of the seat cushion 11A in the left-right direction. The second sensors P2 are arranged in two rows, each row consisting of six second sensors P2 spaced apart in the left-right direction, and spaced apart in the front-rear direction. The six rear second sensors P2 are arranged in positions corresponding to the buttocks of the seated occupant. The six front second sensors P2 are arranged in positions corresponding to the thighs of the seated occupant.

[0025] The control unit 20 has a function of executing an application program (hereinafter also simply referred to as "app") based on information from the pressure sensor P. The control unit 20 has a first control unit 21, a second control unit 22, and a smartphone 23. The first control unit 21, the second control unit 22, and the smartphone 23 each have a CPU, ROM, RAM, rewritable non-volatile memory, etc. (not shown), and execute pre-stored programs. The smartphone 23 further has a screen 23A.

[0026] The first control unit 21 and the second control unit 22 are capable of communicating with the smartphone 23. The first control unit 21 and the second control unit 22 may be provided in the seat main body 11, or may be configured as devices separate from the seat main body 11 and the smartphone 23.

[0027] In this embodiment, an application that provides a three-legged race game is exemplified as the application. The three-legged race game is a game in which a first user and a second user sitting on seat main body 11 move their left and right legs up and down alternately while matching the movements of their respective legs to the movements of the other user, thereby making a character displayed on screen 23A of smartphone 23 run. Note that, unlike an actual three-legged race, the three-legged race game in this embodiment is a game in which the closer the timing of the up and down movements of the left legs or right legs of the first and second users match, the faster the speed of the character becomes.

[0028] The first control unit 21 is connected to each of the first sensors P1 and acquires information from each of the first sensors P1. The second control unit 22 is connected to each of the second sensors P2 and acquires information from each of the second sensors P2.

[0029] The first control unit 21 has a function of setting two first sensors P1 having the strongest response among the six first sensors P1 on the front side as first application sensors to be used by the application. When the first user sits within the first range R1, the first control unit 21 sets a first application sensor from the multiple first sensors P1 and outputs information acquired from the left and right first sensors P1 set as the first application sensors to the smartphone 23. In the following description, of the left and right first sensors P1 set as the first application sensors, the left first sensor P1 will also be referred to as the "first left leg sensor," and the right first sensor P1 will also be referred to as the "first right leg sensor."

[0030] The second control unit 22 has a function of setting the two second sensors P2 having the strongest response among the six second sensors P2 on the front side as second application sensors to be used by the application. When the user sits within the second range R2, the second control unit 22 sets the second application sensors from the multiple second sensors P2 and outputs information acquired from the left and right second sensors P2 set as the second application sensors to the smartphone 23. In the following description, of the left and right second sensors P2 set as the second application sensors, the left second sensor P2 will also be referred to as the "second left leg sensor," and the right second sensor P2 will also be referred to as the "second right leg sensor."

[0031] The smartphone 23 has a function of executing a three-legged race game application based on information from the first application sensor and the second application sensor. The smartphone 23 has a function of changing output based on the degree of coincidence between the timing of information input to the first application sensor and the timing of information input to the second application sensor. Specifically, the smartphone 23 increases the speed of the character on the screen 23A as the degree of coincidence between the timing of information input to the first right leg sensor and the timing of information input to the second right leg sensor increases. Furthermore, the smartphone 23 increases the speed of the character on the screen 23A as the degree of coincidence between the timing of information input to the first left leg sensor and the timing of information input to the second left leg sensor increases.

[0032] In a three-legged race game, the speed of a character is directly linked to the time it takes to reach the goal, and therefore corresponds to an evaluation value in the app. In other words, the higher the evaluation value, the more advantageous the game progresses, and in this embodiment, the speed of a character corresponds to an evaluation value.

[0033] Therefore, in this embodiment, the smartphone 23 increases the evaluation value in the app as the timing of information input to the first right leg sensor and the timing of information input to the second right leg sensor match more closely. Also, the smartphone 23 increases the evaluation value in the app as the timing of information input to the first left leg sensor and the timing of information input to the second left leg sensor match more closely.

[0034] 4, the smartphone 23 has a function of determining that the degree of coincidence of the input timings is higher as the absolute value of the difference ΔP between the pressure value PR1 of the first right leg sensor and the pressure value PR2 of the second right leg sensor acquired simultaneously is smaller. Also, the smartphone 23 has a function of determining that the degree of coincidence of the input timings is higher as the absolute value of the difference between the pressure value of the first left leg sensor and the pressure value of the second left leg sensor acquired simultaneously is smaller.

[0035] In detail, the smartphone 23 calculates the sum S of the absolute value of the difference ΔP between the pressure values ​​PR1, PR2 of the first right leg sensor and the second right leg sensor and the absolute value of the difference between the pressure values ​​of the first left leg sensor and the second left leg sensor over a predetermined period going back from the present time, and determines that the smaller the sum S, the higher the degree of matching of the input timing.

[0036] Next, the operation of the smartphone 23 will be described in detail. When the user launches the three-legged race game app, the smartphone 23 starts the process shown in Fig. 2 (START). In this process, the smartphone 23 first determines whether or not it is in a state where it can communicate with the seat 10 (S1).

[0037] If it is determined in step S1 that the smartphone 23 is not in a state where communication is possible (No), the smartphone 23 ends this process. If it is determined in step S1 that the smartphone 23 is in a state where communication is possible (Yes), the smartphone 23 displays a start image of the three-legged race game on the screen 23A (S2). Note that the start image displays a start button for starting the three-legged race game and an end button for ending the app.

[0038] Furthermore, when it is determined that communication is possible, the smartphone 23 requests the pressure values ​​to be used in the three-legged race game from the first control unit 21 and the second control unit 22. Upon receiving the request, the first control unit 21 and the second control unit 22 configure the first application sensor and the second application sensor, and transmit the pressure values ​​of the respective application sensors to the smartphone 23.

[0039] After step S2, the smartphone 23 determines whether or not the start button displayed on the screen 23A has been selected (S3). If it is determined in step S3 that the start button has been selected (Yes), the smartphone 23 determines whether or not a flag F indicating whether calibration in the three-legged race game has already been performed in the past is 0 (S4).

[0040] Here, calibration is a process of aligning the peak pressure value input from the first user to the first application sensor and the peak pressure value input from the second user to the first application sensor in a three-legged race game to equivalent values.

[0041] If it is determined in step S4 that F is not 0 (No), that is, if calibration has been performed in the past, the smartphone 23 starts the three-legged race game (S9) without performing calibration (S5). If it is determined in step S4 that F is 0 (Yes), that is, if calibration has never been performed in the past, the smartphone 23 performs calibration (S5).

[0042] During calibration, the smartphone 23 displays instructions for each user on the screen 23A. For example, the smartphone 23 displays a message on the screen 23A saying, "Move both legs up and down alternately for a predetermined time." The smartphone 23 sets a correction value to correct the peak values ​​of the pressure values ​​of each left leg sensor acquired during the predetermined time to be equal. Similarly to the left leg sensors, the smartphone 23 also sets a correction value for each right leg sensor to equalize the peak values ​​of the pressure values.

[0043] After step S6, the smartphone 23 sets the flag F to 1 (S6) and executes the three-legged race game (S7). Note that the processing in the three-legged race game will be described in detail later.

[0044] After step S7, or if it is determined No in step S3, the smartphone 23 displays the start image and determines whether or not the end button displayed on the screen 23A has been selected (S8). If it is determined in step S8 that the end button has not been selected (No), the smartphone 23 returns to the processing of step S2. If it is determined in step S8 that the end button has been selected (Yes), the smartphone 23 ends this processing.

[0045] 3, in a three-legged race game, after notifying each user of a signal to start their character, the smartphone 23 acquires pressure values ​​from the pressure sensors P corresponding to each leg of each user (S21). More specifically, in step S21, the smartphone 23 acquires each pressure value from the first left leg sensor, the second left leg sensor, the first right leg sensor, and the second right leg sensor. Furthermore, the smartphone 23 corrects the pressure value on the first user's side or the pressure value on the second user's side so that the peaks of the pressure value on the first user's side and the pressure value on the second user's side are aligned.

[0046] After notifying the user of the signal to start the character, the smartphone 23 may notify each user of the timing for inputting information to each left leg sensor or each right leg sensor. Specifically, the smartphone 23 may notify each user of the timing for inputting information to each left leg sensor or each right leg sensor by voice, for example, a message such as "1, 2, 1, 2, . . . " or a message such as "in, out, in, out, . . . ". The notification of the input timing may also be made by a simple sound other than voice, an image, a light, a vibration, or the like.

[0047] After step S21, the smartphone 23 calculates the sum S of the absolute values ​​of the differences in pressure values ​​between the first right leg sensor and the second right leg sensor and the absolute values ​​of the differences in pressure values ​​between the first left leg sensor and the second left leg sensor over a predetermined period going back from the present time (S22). In this embodiment, each pressure value is acquired every 50 ms, and the predetermined period is set to 0.5 s. As a result, the number of differences acquired over the predetermined period is 10 for the right leg and 10 for the left leg.

[0048] After step S22, the smartphone 23 calculates the degree of coincidence D using the sum S and the following formula (1) (S23). D=1-S / 20460 (1)

[0049] Here, the pressure value data is represented in 10 bits. Therefore, the minimum difference between two pressure values ​​is 0, and the maximum difference is 1023. The number of differences obtained during a predetermined period is 10 for the right leg and 10 for the left leg, so the maximum value of the sum S of all differences is 20,460. Therefore, the ratio calculated by dividing the sum S of all differences during a predetermined period by the maximum value of 20,460 for the sum S indicates that the input timing of each user is more misaligned the smaller the ratio. Then, by subtracting this ratio from 1, the degree of agreement D, which indicates the degree to which the input timing of each user is aligned, is calculated. Note that the greater the degree of agreement D, the greater the degree of agreement between the input timing of each user.

[0050] After step S23, the smartphone 23 sets the speed of the character based on the degree of coincidence D (S24). In detail, in step S24, the smartphone 23 increases the speed of the character as the degree of coincidence D increases.

[0051] After step S24, the smartphone 23 moves the character on the screen 23A at the speed set in step S23 (S25). After step S25, the smartphone 23 determines whether the character has reached the goal (S26).

[0052] If it is determined in step S26 that the character has not reached the goal (No), the smartphone 23 returns to the processing of step S21. If it is determined in step S26 that the character has reached the goal (Yes), the smartphone 23 displays the result on the screen 23A (S27) and ends this processing.

[0053] Next, a description will be given of an example of the operation of the control unit 20. In the following example, a case where calibration has not been performed in the past will be described.

[0054] 1, when a first user is sitting in a first range R1 on the right side of seat 10 and a second user is sitting in a second range R2 on the left side, and the first user operates smartphone 23 to launch an app for a three-legged race game, smartphone 23 requests pressure values ​​to be used in the three-legged race game from first control unit 21 and second control unit 22. In response to the request, first control unit 21 and second control unit 22 transmit the pressure values ​​of the respective app sensors to smartphone 23.

[0055] Smartphone 23 displays a start image on screen 23A, and when the first user selects the start button on the start image, calibration is executed (S3: Yes → S4: Yes → S5). In the calibration, instructions for each user are displayed on screen 23A, and each user moves both legs up and down alternately in accordance with the instructions. Note that each user may look at screen 23A of smartphone 23 together, or may look at the screen of a large monitor to which smartphone 23 is connected together.

[0056] When the calibration is completed, the smartphone 23 executes a three-legged race game (S7). In the three-legged race game, each user alternately moves both legs up and down while synchronizing their leg movements. In the three-legged race game, if the leg movements of each user are not synchronized, the speed of the characters on the screen 23A is slow, so each user tries to synchronize their leg movements by, for example, synchronizing their voices.

[0057] In the three-legged race game, as the leg movements of the users become synchronized, the speed of the character increases. When the character reaches the goal, the smartphone 23 displays the time from the start to the goal as a result, and ends the three-legged race game.

[0058] As described above, the following effects can be obtained in this embodiment. Since the output is changed based on the degree of coincidence of the timing of information input to each right leg sensor or each left leg sensor, a three-legged race game app can be provided to the user, thereby improving the entertainment value of the seat 10.

[0059] The present invention is not limited to the above-described embodiment, but can be used in various forms as exemplified below. In the following description, members having substantially the same structure as those in the above-described embodiment are given the same reference numerals, and their description will be omitted.

[0060] The method for setting the application sensor is not limited to the method described in the above embodiment. For example, as shown in Fig. 5, the application sensor may be set by setting an origin at a predetermined position on the seat cushion 11A and determining the center of gravity of the user based on the set origin.

[0061] Specifically, in this example, the origin is set to a position equidistant from the two pressure sensors Pa, Pb adjacent to the left and right of the rear pressure sensors P and the two pressure sensors Pc, Pd located in front of these pressure sensors Pa, Pb, and the left of the origin is set to the positive x-coordinate, and the rear of the origin is set to the positive y-coordinate. The first control unit 21 or the second control unit 22 (hereinafter simply referred to as the "seat control unit") calculates the x-coordinate Gx and y-coordinate Gy of the center of gravity G based on the moment acting on the origin from each position of the multiple pressure sensors P that detect pressure values ​​equal to or greater than a predetermined value corresponding to the user being seated.

[0062] Specifically, the seat control unit obtains the x coordinate Gx and the y coordinate Gy of the center of gravity G by the following equations (2) and (3). Gx=ΣFn·xn / ΣFn (2) Gy=ΣFn·yn / ΣFn (3) Fn: pressure value of the nth pressure sensor P among multiple pressure sensors P that detect a pressure value equal to or greater than a predetermined value xn: x coordinate of the nth pressure sensor P yn: y coordinate of the nth pressure sensor P

[0063] When pressure values ​​equal to or greater than a predetermined value are applied only to the four pressure sensors Pa to Pd shown in FIG. 5, the seat control section calculates the x-coordinate Gx and y-coordinate Gy of the center of gravity G using the following equations (4) and (5). Gx={Fa·(-xa)+Fc·(-xc)+Fb·xb+Fd·xd} / (Fa+Fb+Fc+Fd) ···(4) Gy={Fc·(-yc)+Fd·(-yd)+Fa·ya+Fb·yb} / (Fa+Fb+Fc+Fd) ···(5) Here, the symbols added after the symbols F and x correspond to the symbols added after the pressure sensor P. That is, the pressure value of the pressure sensor Pa is Fa, and the x, y coordinates of the pressure sensor Pa are −xa, ya.

[0064] Since the origin is set at an equal distance from the four pressure sensors Pa to Pd, the above-mentioned equations (5) and (6) become the following equations (7) and (8). Gx={(Fb+Fd)-(Fa+Fc)} / (Fa+Fb+Fc+Fd) ···(7) Gy={(Fa+Fb)-(Fc+Fd)} / (Fa+Fb+Fc+Fd) ···(8)

[0065] After determining the x-coordinate Gx and y-coordinate Gy of the center of gravity G, the seat control unit sets the application sensors based on the center of gravity G. For example, in an application for a three-legged race game that uses information on the load from both legs of the user as in the above embodiment, the seat control unit can set the two pressure sensors Pc and Pd located in front of the center of gravity G as the application sensors.

[0066] A mark that can be recognized by the user as an application sensor may be provided on the seat surface of the seat cushion 11A. In this case, the seat control unit may execute the application using the pressure sensor corresponding to the mark as the application sensor.

[0067] In the above embodiment, the pressure sensor P is provided only in the seat cushion 11A, but the present invention is not limited to this, and the pressure sensor P may be provided in the seat back 11B.

[0068] In the above embodiment, the seat body 11 is shaped like a bench and can accommodate two or more users, but the present invention is not limited to this. For example, as shown in Fig. 6, the seat body 30 may have a first seat body 31 and a second seat body 32 that is separate from the first seat body 31.

[0069] The first seat body 31 is seatable for a first user and includes a seat cushion 31A, a seat back 31B, and a headrest 31C. The seat cushion 31A and the seat back 31B include a first sensor P1 that receives information from the first user. The first sensor P1 is connected to the first control unit 21. Note that the first sensor P1 may be provided in at least one of the seat cushion 31A, the seat back 31B, and the headrest 31C.

[0070] The second seat body 32 is seatable for a second user and includes a seat cushion 32A, a seat back 32B, and a headrest 32C. The seat cushion 32A and the seat back 32B include a second sensor P2 that receives information from the second user. The second sensor P2 is connected to the first control unit 21. The second sensor P2 may be provided in at least one of the seat cushion 32A, the seat back 32B, and the headrest 32C.

[0071] The smartphone 23 changes the output based on the degree of coincidence between the timing of information input to the first sensor P1 by the first user and the timing of information input to the second sensor P2 by the second user. Specifically, the smartphone 23 is capable of executing a three-legged race game app similar to that of the above embodiment. Even in this configuration, the same effects as those of the above embodiment can be obtained.

[0072] In this embodiment, an app may be employed in which a first user and a second user input pressure using only one first seat body 31. Specifically, the first user may manually press the pressure sensor P of the seat cushion 31A, and the second user may manually press the pressure sensor P of the seat back 31B. In this case, for example, an app such as a game in which points increase exponentially when two users simultaneously press the pressure sensors P may be employed.

[0073] In this game, for example, if two people get their timing right once, 10 points are added, if they get it right twice in a row, 100 points are added, if they get it right three times in a row, 1000 points are added, if they get it right four times in a row, 10,000 points are added, and if they don't get their timing right, the game starts over from 10 points. Note that the game is not limited to one in which points increase according to the number of times the timing is right, and it may also be one in which points increase the more closely the timing matches.

[0074] In the above embodiment, unlike an actual three-legged race, the speed of the character is increased when the timing of the movements of the right legs or the left legs of each user closely match, but the present invention is not limited to this. For example, as in an actual three-legged race, the speed of the character may be increased when the timing of the movements of the left and right inner legs or the left and right outer legs of each user closely match.

[0075] The determination of the degree of coincidence of the timing of inputting information to the sensors is not limited to the above embodiment. For example, the degree of coincidence may be determined to be higher as the difference between the time when the pressure value from the first user reaches its peak and the time when the pressure value from the second user reaches its peak is smaller.

[0076] The character may be a car, a plane, etc. The character may also move relative to the background, with the background moving around the character.

[0077] The seat may be a vehicle seat used in an automobile, a ship, or the like, or may be a seat installed indoors in a public facility or the like.

[0078] In the above embodiment, the control unit is configured with the first control unit 21, the second control unit 22, and the smartphone 23, but the present invention is not limited to this. For example, the control unit may be connected to each sensor in the seat and also to a monitor of a car navigation system or the like. In this case, the control unit may execute an app based on information from each sensor to cause a character on the monitor to move.

[0079] The control unit may increase the speed of the character as the coincidence of the timing of input of information to the three or more sensors increases. In this case, for example, a three-person four-legged race game may be adopted as the application.

[0080] The control unit may change the output based on the degree of coincidence of the timing of input of information to the plurality of sensors. For example, the control unit may move an object to be moved by the control unit when the degree of coincidence of the input timing is equal to or greater than a predetermined value, and may not move the object when the degree of coincidence of the input timing is less than the predetermined value. Note that the object may be, for example, a character on the screen, a vehicle such as a cart that the user rides, or a robot.

[0081] The sensor may be any sensor that receives information from a user, such as a light sensor, capacitance sensor, temperature sensor, humidity sensor, radio wave sensor, sound sensor, etc. The information is not limited to pressure values ​​and may be any type of information.

[0082] In the embodiment of Figure 1, two rows of sensors are provided, each row being aligned in the left-right direction. However, the present invention is not limited to this; for example, the number of rows of sensors aligned in the left-right direction may be one or three or more.

[0083] In the above embodiment, two control units (first control unit 21 and second control unit 22) are provided, but the present invention is not limited to this, and one control unit may be configured to acquire signals from all sensors provided in the seat body.

[0084] The application sensor settings may be reset when the user stands up from the seat 10.

[0085] 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.
