Description

The present invention relates to a seat system including a seat having a sensor.

Conventionally, a vehicle seat is known in which multiple pressure sensors are arranged on the seat to detect the seating position of the occupant (Patent Document 1).

JP 2017-65504 A

However, conventional vehicle seats only evaluate and indicate the driver's seating posture, which means they are not very effective.

The present invention aims to improve the entertainment value of seats in order to offer new value to seats.

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.

With this configuration, the output is changed based on the degree of coincidence between the timing of information input to the two sensors, making it possible to provide users with a variety of application programs, such as games, thereby improving the entertainment value of the seat.

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

Furthermore, 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.

With this configuration, it is possible to provide users with games such as a three-legged race, for example.

Furthermore, the sensor may be a pressure sensor, 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 timing.

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

The control unit may also notify the timing of information input to the sensor.

Furthermore, 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 at which the first user inputs information to the first sensor and the timing at which the second user inputs information to the second sensor.

The seat body may 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.

This invention can improve the entertainment value of seats.

In addition, the control unit can increase the speed of the character moving on the screen the more closely the timing of information input to the sensors matches, allowing the user to play games such as a three-legged race, for example.

FIG. 10 is a diagram illustrating a modified example of a method for setting an application sensor. FIG. 1 shows a seat system with two seat bodies.

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, and up and down are based on the user sitting in the seat 10.

The seat 10 is a bench-like seat and includes a seat body 11 with a seat surface that is longer left-to-right than it is front-to-back, and multiple pressure sensors P as an example of a sensor. The seat body 11 can accommodate two or more users. The seat body 11 includes a seat cushion 11A and a seat back 11B.

The pressure sensor P is a sensor that acquires pressure, which is information used to identify the physical state (posture and movement) of the user sitting in the seat body 11. The pressure sensor P is located between the surface and pad of the seat cushion 11A.

The multiple pressure sensors P include multiple first sensors P1 to which pressure information is input from a first user, and multiple second sensors P2 to which pressure information is input from a second user. In this embodiment, the number of first sensors P1 and the number of second sensors P2 are each 12.

The multiple first sensors P1 are arranged within a first range R1, which is the range to the right of the left-right center of the seat cushion 11A. The multiple first sensors P1 are arranged so that two rows of six first sensors P1 are spaced apart in the left-right direction, and each row is spaced apart in the front-to-rear direction. The six rear first sensors P1 are arranged in positions corresponding to the buttocks of the seated occupant. The six front first sensors P1 are arranged in positions corresponding to the thighs of the seated occupant.

The multiple second sensors P2 are arranged within a second range R2, which is the range to the left of the center in the left-right direction of the seat cushion 11A. The multiple second sensors P2 are arranged so that two rows of six second sensors P2 are spaced apart in the left-right direction, and each row is spaced apart in the front-to-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.

The control unit 20 has the function of executing an application program (hereinafter 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 also has a screen 23A.

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

In this embodiment, an example of the app is an app that provides a three-legged race game. The three-legged race game is a game in which a first user and a second user seated on the seat main body 11 move their left and right legs up and down alternately while matching the movements of their partner's legs, causing a character displayed on the screen 23A of the smartphone 23 to 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 first and second users' left and right legs match, the greater the speed of the character.

The first control unit 21 is connected to each first sensor P1 and acquires information from each first sensor P1. The second control unit 22 is connected to each second sensor P2 and acquires information from each second sensor P2.

The first control unit 21 has a function of setting the two first sensors P1 with the strongest response among the six front first sensors P1 as the 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 the first application sensor from the multiple first sensors P1 and outputs information obtained 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."

The second control unit 22 has a function of setting the two second sensors P2 with the strongest response among the six second sensors P2 on the front side as the 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 obtained 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."

The smartphone 23 has a function to execute a three-legged race game app based on information from the first app sensor and the second app sensor. The smartphone 23 has a function to change output based on the degree of coincidence between the timing of information input to the first app sensor and the timing of information input to the second app sensor. In detail, the smartphone 23 increases the speed of the character on the screen 23A the closer 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. Furthermore, the smartphone 23 increases the speed of the character on the screen 23A the closer 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.

In a three-legged race game, the character's speed is directly linked to the time it takes to reach the finish line from the start, and is therefore equivalent to the evaluation value in the app. In other words, the higher the evaluation value, the more advantageous the player's progress in the game. In this embodiment, the character's speed corresponds to the evaluation value.

Therefore, in this embodiment, the smartphone 23 increases the evaluation value in the app the closer the 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. Furthermore, the smartphone 23 increases the evaluation value in the app the closer the 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.

As shown in FIG. 4, the smartphone 23 has a function of determining that the degree of matching of the input timing is higher the smaller 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, which are acquired simultaneously. Furthermore, the smartphone 23 has a function of determining that the degree of matching of the input timing is higher the smaller 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, which are acquired simultaneously.

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 of time going back from the present time, and determines that the smaller the sum S, the higher the degree of coincidence of the input timing.

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).

If it is determined in step S1 that communication is not possible (No), the smartphone 23 ends this processing. If it is determined in step S1 that 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.

Furthermore, if 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 each application sensor to the smartphone 23.

After step S2, the smartphone 23 determines whether 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 a flag F indicating whether calibration for the three-legged race game has already been performed is 0 (S4).

Here, calibration refers to the 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.

If it is determined in step S4 that F = 0 is not true (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 = 0 (Yes), that is, if calibration has never been performed in the past, the smartphone 23 performs calibration (S5).

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 specified 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 specified time to be equal. The smartphone 23 also sets a correction value for each right leg sensor to align the peak values of the pressure values, just like the left leg sensors.

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

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

As shown in FIG. 3, in a three-legged race game, after the smartphone 23 notifies each user of a signal to start their character, it acquires pressure values from the pressure sensors P corresponding to each leg of each user (S21). Specifically, in step S21, the smartphone 23 acquires pressure values from the first left leg sensor, second left leg sensor, first right leg sensor, and 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 values on the first user's side and the second user's side are aligned.

After announcing 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 by voice, for example, a message such as "1, 2, 1, 2, ..." or a message such as "in, out, in, out, ...". The input timing may also be notified by simple sound, video, light, vibration, or the like other than voice.

After step S21, the smartphone 23 calculates the sum S of the absolute values of the difference in pressure values between the first right leg sensor and the second right leg sensor and the absolute values of the difference 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 0.5 s. As a result, the number of differences obtained over the predetermined period is 10 for the right leg and 10 for the left leg.

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)

Here, pressure value data is represented in 10 bits. Therefore, the minimum difference between two pressure values is 0, and the maximum is 1023. The number of differences obtained over a specified 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 over a specified period by the maximum value of 20,460 for the sum S, indicates that the smaller the ratio, the more misaligned the input timing of each user is. 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 more closely the input timing of each user is aligned.

After step S23, the smartphone 23 sets the character's speed based on the degree of matching D (S24). In detail, in step S24, the smartphone 23 increases the character's speed as the degree of matching D increases.

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).

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.

Next, an example of the operation of the control unit 20 will be described. The following example shows a case where calibration has not been performed in the past.

As shown in FIG. 1, when a first user is sitting within a first range R1 on the right side of the seat 10 and a second user is sitting within a second range R2 on the left side, and the first user operates the smartphone 23 to launch a three-legged race game app, 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. In response to the request, the first control unit 21 and the second control unit 22 transmit the pressure values of each app sensor to the smartphone 23.

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

Once calibration is complete, the smartphone 23 executes a three-legged race game (S7). In the three-legged race game, each user alternates between moving their 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 screen 23A will be slow, so each user will try to synchronize their leg movements by, for example, synchronizing their voices.

In the three-legged race game, as the leg movements of each user become synchronized, the character's speed increases. When the character reaches the finish line, the smartphone 23 displays the time from the start to the finish line as the result, and the three-legged race game ends.

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.

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, components with substantially the same structure as those in the above-described embodiment will be assigned the same reference numerals, and their description will be omitted.

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

Specifically, in this example, the origin is set to a position equidistant from the two pressure sensors Pa and Pb adjacent to the left and right of the rear pressure sensors P and the two pressure sensors Pc and Pd located in front of these pressure sensors Pa and Pb, with the left of the origin set to the positive x-coordinate and the rear of the origin 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") determines 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 above a predetermined value corresponding to the user being seated.

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 the 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;

When a pressure value equal to or greater than a predetermined value is applied to only the four pressure sensors Pa to Pd shown in FIG. 5, the seat control unit 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.

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)

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 a three-legged race game application 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 application sensors.

The seat cushion 11A may have a mark on its surface that the user can recognize as an application sensor. In this case, the seat control unit may execute the application using the pressure sensor corresponding to the mark as the application sensor.

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 also be provided in the seat back 11B.

In the above embodiment, a bench-like seat body 11 capable of seating two or more users was illustrated, 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.

The first seat body 31 is seatable for the 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.

The second seat body 32 allows a second user to sit on it 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. Note that the second sensor P2 may be provided in at least one of the seat cushion 32A, the seat back 32B, and the headrest 32C.

The smartphone 23 changes its output based on the degree of coincidence between the timing of information input by the first user to the first sensor P1 and the timing of information input by the second user to the second sensor P2. 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.

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 press the pressure sensor P on the seat cushion 31A with their hand, and the second user may press the pressure sensor P on the seat back 31B with their hand. In this case, for example, an app such as a game in which points increase exponentially when two users press the pressure sensors P at the same time can be employed.

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, and if they get it right four times in a row, 10,000 points are added. If the timing isn't 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 can also be one in which points increase the more closely the timing matches.

In the above embodiment, unlike in an actual three-legged race, the character's speed was increased when there was a high degree of matching between the movement timing of the right legs or left legs of each user, but the present invention is not limited to this. For example, as in an actual three-legged race, the character's speed may be increased when there is a high degree of matching between the movement timing of the left and right inner legs or the left and right outer legs of each user.

The determination of the degree of coincidence in the timing of information input to the sensor is not limited to the above embodiment. For example, the degree of coincidence may be determined to be higher the smaller 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.

A character may be a car, a plane, etc. The character may also move relative to the background around the character by moving the background.

The seat may be a vehicle seat used in automobiles, ships, etc., or a seat installed indoors in public facilities, etc.

In the above embodiment, the control unit is configured from a first control unit 21, a second control unit 22, and a 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, causing a character on the monitor to move.

The control unit may increase the character's speed as the degree of coincidence between the timing of information input to three or more sensors increases. In this case, the app could be, for example, a three-person, four-legged race game.

The control unit can change the output based on the degree of coincidence between the timing of information input to multiple sensors. For example, the control unit can move an object that the control unit is moving when the degree of coincidence between the input timings is equal to or greater than a predetermined value, and can prevent the object from moving when the degree of coincidence between the input timings is less than the predetermined value. The object may be, for example, a character on the screen, a vehicle such as a cart that the user rides in, or a robot.

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

In the embodiment shown in 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.

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.

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

The sensors may also be installed 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, doors, floor), etc.

The elements described in the above embodiments and variations may be implemented in any combination.
