Description

[Technical Field]

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

[0002] Conventionally, a known seat system includes a seat body, a plurality of sensors provided in the seat body, and a control unit that executes an application program (hereinafter simply referred to as "app") based on information from the sensors (see Patent Document 1). In this technology, the seat body is configured as a seat for one person. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 2019-182167 Summary of the Invention [Problem to be solved by the invention]

[0004] It is also conceivable to provide a seat system in which multiple sensors are provided on a bench-like seat body that is long in the left-right direction, allowing one or more users to run an app. However, in this case, if the user sits in a position on the seat body that is not located near the sensor, the control unit cannot obtain information from the sensor, which causes a problem in that the app cannot be run. It is also conceivable to have the user sit in a specific position on the bench-like seat body, but in this case, the location where the user can sit is extremely limited, which causes a problem of reduced user convenience.

[0005] Therefore, the present invention aims to prevent extreme restrictions on where a user can sit in a seat system that has a seat body that is long in the left-right direction, while preventing the control unit from being unable to obtain information from a sensor and being unable to execute an app. [Means for solving the problem]

[0006] In order to solve the above problem, the seat system of the present invention comprises a seat body that is long in the left-right direction, a plurality of sensors that are provided on the seat body and acquire information to identify the physical condition of a user sitting on the seat body, the plurality of sensors being located at different positions in the left-right direction, and a control unit that executes an application program based on information from the sensors. Based on the outputs of the multiple sensors, the control unit sets some of the multiple sensors located at different positions in the left-right direction that have a stronger response than the other sensors as app sensors to be used by the application program.

[0007] According to this configuration, when a user sits in a first position on the seat body, some of the sensors corresponding to the first position are set as application sensors. Also, when a user sits in a second position on the seat body that is different from the first position, some of the sensors corresponding to the second position are set as application sensors. Therefore, in a seat system that includes a seat body that is long in the left-right direction, it is possible to prevent extreme restrictions on where a user can sit, while also preventing the control unit from being unable to obtain information from the sensors and being unable to execute an application.

[0008] The sensor may also be a pressure sensor.

[0009] According to this configuration, the control unit can execute an application that operates based on a change in pressure applied to the pressure sensor by the user.

[0010] The sensor may also include a plurality of first sensors arranged in the left-right direction, and a plurality of second sensors arranged in the left-right direction, the second sensors being located at different positions in an orthogonal direction perpendicular to the left-right direction relative to the first sensors.

[0011] According to this configuration, the control unit can identify a greater variety of user actions, allowing the control unit to execute a variety of applications.

[0012] The control unit may also set two first sensors having the strongest response among the plurality of first sensors and two second sensors having the strongest response among the plurality of second sensors as the application sensors.

[0013] According to this configuration, it is possible to set an optimum sensor as the application sensor.

[0014] In addition, the second sensors may be arranged in the perpendicular direction to the first sensors, and the control unit may set two first sensors having the strongest response among the plurality of first sensors and second sensors arranged in the perpendicular direction to each of the two first sensors having the strongest response as the sensors for the application.

[0015] According to this configuration, a signal from the second sensor is not required in setting the application sensor, which simplifies the processing in the control unit.

[0016] The control unit may also have a first control unit connected to the first sensor and the second sensor located within a first range in the left-right direction, and a second control unit connected to the first sensor and the second sensor located within a second range in the left-right direction that is different from the first range, and the first control unit or the second control unit may output an instruction to encourage the user to sit back down if the number of first sensors whose response strength is equal to or greater than a predetermined value is less than a standard number.

[0017] With this configuration, the sensors are identified by two control units, which reduces the processing load on one control unit. Also, if the number of first sensors whose response strength is equal to or greater than a predetermined value is less than the standard number, it is highly likely that the user is not sitting in an appropriate position. In this case, by outputting an instruction to prompt the user to reseat, the application sensor settings can be reliably performed by either the first control unit or the second control unit.

[0018] The seat body may include a seat cushion and a seat back, the first sensor may be located at a rear portion of the seat cushion, and the second sensor may be located at a front portion of the seat cushion.

[0019] With this configuration, pressure from the user is more likely to be applied to the first sensor than to the second sensor, so that, for example, when a second sensor aligned perpendicular to each of the two most responsive first sensors is set as an application sensor, the two most responsive first sensors can be more reliably selected. [Effects of the Invention]

[0020] According to the present invention, in a seat system having a seat body that is long in the left-right direction, it is possible to prevent the user's seating location from being extremely restricted, while also preventing the control unit from being unable to obtain information from the sensor and being unable to execute an app.

[0021] Furthermore, by using a pressure sensor as the sensor, an application that operates based on changes in pressure applied to the pressure sensor by the user can be executed by the control unit.

[0022] Furthermore, by providing a plurality of first sensors and a plurality of second sensors on the seat body, the types of user actions that can be discriminated by the control unit can be increased, allowing a variety of applications to be executed by the control unit.

[0023] Furthermore, by setting the two first sensors with the strongest response and the two second sensors with the strongest response as the application sensors, it is possible to set the optimum sensors as the application sensors.

[0024] Furthermore, by setting the two first sensors with the strongest response and the second sensors aligned perpendicular to each of the two first sensors with the strongest response as sensors for the application, signals from the second sensors are not required when setting the sensors for the application, thereby simplifying processing in the control unit.

[0025] Furthermore, by configuring the two control units to distinguish between sensors, the processing load on one control unit can be reduced. Also, if the number of first sensors whose response strength is equal to or greater than a predetermined value is less than the standard number, it is highly likely that the user is not sitting in an appropriate position. In this case, by outputting an instruction to prompt the user to reseat, the application sensor settings can be reliably performed by either the first control unit or the second control unit.

[0026] Furthermore, by configuring the first sensor to be located at the rear of the seat cushion and the second sensor to be located at the front of the seat cushion, pressure from the user is more likely to be applied to the first sensor than to the second sensor. Therefore, for example, when second sensors aligned perpendicular to two first sensors with the strongest response are set as sensors for an application, the two first sensors with the strongest response can be more reliably selected.

[0028] 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.

[0029] 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 includes a seat cushion 11A and a seat back 11B.

[0030] 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.

[0031] The pressure sensors P include a plurality of first sensors P1 arranged in the left-right direction and a plurality of second sensors P2 arranged in the left-right direction. In this embodiment, the number of the first sensors P1 and the number of the second sensors P2 are each 12.

[0032] The first sensors P1 are located at the rear of the seat cushion 11A and are arranged at regular intervals in the left-right direction. The second sensors P2 are located at the front of the seat cushion 11A and are arranged at regular intervals in the left-right direction. Each second sensor P2 is arranged at an interval in the front-rear direction, which is an example of an orthogonal direction perpendicular to the left-right direction, relative to the corresponding first sensor P1.

[0033] 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.

[0034] 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.

[0035] In this embodiment, an application that provides a 100-meter sprint game is exemplified as the application. The 100-meter sprint game is a game in which a user sitting on the seat main body 11 moves both legs up and down alternately to make a character displayed on the screen 23A of the smartphone 23 run.

[0036] The first control unit 21 is connected to six first sensors P1 and six second sensors P2 located within a first range R1 in the left-right direction of the seat cushion 11A. The second control unit 22 is connected to six first sensors P1 and six second sensors P2 located within a second range R2 different from the first range R1 in the left-right direction of the seat cushion 11A. In this embodiment, the first range R1 is defined as the range from the center to the right end of the seat cushion 11A in the left-right direction, and the second range R2 is defined as the range from the center to the left end of the seat cushion 11A in the left-right direction.

[0037] As shown in FIG. 2(a), the first control unit 21 has a function of setting the two most responsive first sensors P1 among the six first sensors P1 on the right side and the two most responsive second sensors P2 among the six second sensors P2 on the right side as application sensors to be used by the application. In FIG. 2, the two most responsive first sensors P1 and the two most responsive second sensors P2 are indicated by hatching. When the user sits within the first range R1, the first control unit 21 sets application sensors from the multiple pressure sensors P within the first range R1 and outputs information acquired from the four pressure sensors P set as application sensors to the smartphone 23.

[0038] 2(b), the second control unit 22 has a function of setting the two first sensors P1 with the strongest response among the six first sensors P1 on the left side and the two second sensors P2 with the strongest response among the six second sensors P2 on the left side as application sensors to be used by the application. When the user sits within the second range R2, the second control unit 22 sets application sensors from the multiple pressure sensors P within the second range R2 and outputs information obtained from the four pressure sensors P set as the application sensors to the smartphone 23.

[0039] As shown in FIG. 2(c), the first control unit 21 has a function of outputting an instruction to prompt the user to sit back down if the number of first sensors P1 whose response strength is equal to or greater than the predetermined value is less than the standard number. Similarly, the second control unit 22 has a function of outputting an instruction to prompt the user to sit back down if the number of first sensors P1 whose response strength is equal to or greater than the predetermined value is less than the standard number. Here, the standard number is the number of sensors predicted to be arranged within the width of the buttocks of a user with an average body size, which is four in this embodiment. The predetermined value is set to a relatively low value. If the first control unit 21 or the second control unit 22 determines that the number of sensors whose response strength is equal to or greater than the predetermined value is less than four, such as when the user sits across the first range R1 and the second range R2, the first control unit 21 or the second control unit 22 outputs an error signal to the smartphone 23 corresponding to an instruction to prompt the user to sit back down.

[0040] Next, a detailed description will be given of the operations of the smartphone 23, the first control unit 21, and the second control unit 22. The smartphone 23 repeatedly executes the process shown in FIG.

[0041] 3, the smartphone 23 first determines whether or not the 100m sprint game app has been started (S1). If it is determined in step S1 that the app has not been started (No), the smartphone 23 ends this process.

[0042] If it is determined in step S1 that the app has been started (Yes), the smartphone 23 outputs a request to the first control unit 21 and the second control unit 22 to instruct them to output information acquired by the pressure sensor P (hereinafter also referred to as the "sensor signal") to the smartphone 23 (S2).

[0043] After step S2, the smartphone 23 determines whether or not a sensor signal has been acquired from the first control unit 21 or the second control unit 22 (S3). If it is determined in step S3 that a sensor signal has been acquired (Yes), the smartphone 23 executes an app based on the acquired sensor signal (S4).

[0044] Specifically, the smartphone 23 determines whether the user's body is leaning forward, backward, left, or right based on the pressure values ​​of the pressure sensors P, and allows the user to select the start or end of the 100m sprint game by moving a cursor displayed on the screen 23A in the direction of the body lean. After starting the 100m sprint game, the smartphone 23 determines whether the user is moving both legs up and down alternately based on sensor signals from the left and right second sensors P2, and makes the character displayed on the screen 23A run.

[0045] After step S4, the smartphone 23 determines whether the app has been terminated (S5). If it is determined in step S5 that the app has not been terminated (No), the smartphone 23 returns to the processing of step S4. If it is determined in step S5 that the app has been terminated (Yes), the smartphone 23 transmits a termination signal indicating that the app has been terminated to the first control unit 21 and the second control unit 22 (S6), and terminates this processing.

[0046] If it is determined in step S3 that a sensor signal has not been acquired from either the first control unit 21 or the second control unit 22 (No), the smartphone 23 determines whether or not an error signal has been received from the first control unit 21 or the second control unit 22 (S7). If it is determined in step S7 that an error signal has not been received from either the first control unit 21 or the second control unit 22 (No), the smartphone 23 returns to the processing of step S2.

[0047] If it is determined in step S7 that an error signal has been received from the first control unit 21 or the second control unit 22 (Yes), the smartphone 23 outputs an instruction to encourage the user to reseat based on the error signal (S8), and returns to the processing of step S2. Here, the instruction to encourage the user to reseat may be displayed as an image on the screen 23A, may be output as an audio signal, or may be a combination of an image and an audio signal.

[0048] The first control unit 21 and the second control unit 22 repeatedly execute the processing shown in Fig. 4. In the following explanation, the processing in the first control unit 21 will be explained as a representative, and the processing in the second control unit 22 will not be explained as it is similar.

[0049] 4, the first control unit 21 first determines whether or not there is a request for a sensor signal from the smartphone 23 (S21). If it is determined in step S21 that there is no request for a sensor signal (No), the first control unit 21 ends this process.

[0050] If it is determined in step S21 that there is a request for a sensor signal (Yes), the first control unit 21 determines whether or not there are four or more first sensors P1 whose pressure values ​​are equal to or greater than a predetermined value, thereby determining whether or not the user's body is located within the first range R1 (S22). If it is determined in step S22 that there are four or more first sensors P1 whose pressure values ​​are equal to or greater than a predetermined value (Yes), the first control unit 21 sets the first sensor P1 whose pressure value is highest and the first sensor P1 whose pressure value is second highest as sensors for the application (S23).

[0051] After step S23, the first control unit 21 sets the second sensor P2 with the highest pressure value and the second sensor P2 with the second highest pressure value as application sensors (S24). After step S24, the first control unit 21 outputs the sensor signals acquired from the pressure sensors P set as application sensors to the smartphone 23 (S25).

[0052] After step S25, the first control unit 21 determines whether or not an end signal has been received from the smartphone 23 (S26). If it is determined in step S26 that an end signal has not been received (No), the first control unit 21 returns to the processing of step S25. If it is determined in step S26 that an end signal has been received (Yes), the first control unit 21 resets the settings of the application sensor (S27) and ends this processing.

[0053] If it is determined in step S22 that there are not four or more first sensors P1 whose pressure values ​​are equal to or greater than the predetermined value (No), the first control unit 21 determines whether the number of first sensors P1 whose pressure values ​​are equal to or greater than the predetermined value is 0 (S28). If the number of first sensors P1 whose pressure values ​​are equal to or greater than the predetermined value is 0 in step S28 (Yes), the user is not sitting within the first range R1, so the first control unit 21 ends this process without setting an application sensor.

[0054] If it is determined in step S28 that the number of first sensors P1 whose pressure value is equal to or greater than the predetermined value is not 0 (No), since at least a part of the user's body is outside the first range R1, the first control unit 21 outputs an error signal to the smartphone 23 to instruct the user to reseat (S29), and terminates this process.

[0055] Next, a specific example of the operations of the smartphone 23, the first control unit 21, and the second control unit 22 will be described. 2(a), when the user sits near the right end of the seat body 11, for example, the four first sensors P1 on the right side output pressure values ​​equal to or greater than a predetermined value to the first control unit 21. When the user sitting in the seat body 11 launches an app on the smartphone 23, the smartphone 23 requests the first control unit 21 and the second control unit 22 for sensor signals (steps S1 and S2 in FIG. 3).

[0056] When the first control unit 21 receives a request for a sensor signal from the smartphone 23 (S21: Yes), it determines Yes in step S22 and sets up sensors for the application (S23, 24). Specifically, the first control unit 21 sets up four pressure sensors P indicated by hatching with dots as sensors for the application. Thereafter, the first control unit 21 outputs the sensor signals acquired from each pressure sensor P set up as a sensor for the application to the smartphone 23 (S25).

[0057] On the other hand, since no sensor signal is output from the pressure sensor P to the second control unit 22, even if the second control unit 22 receives a request for a sensor signal from the smartphone 23 (S21: Yes), the second control unit 22 ends the processing of Figure 4 without setting up a sensor for the app or outputting an error signal (S22: No → S28: Yes → END).

[0058] When the smartphone 23 receives the sensor signal from the first control unit 21 (S3: Yes), it executes the application based on the sensor signal (S4). Specifically, the smartphone 23 moves a cursor on the screen 23A in accordance with the tilt of the user's body, and makes a character on the screen 23A run in accordance with the movement of the user's legs moving up and down alternately.

[0059] When the user ends the app, the smartphone 23 transmits an end signal to the first control unit 21 (S5: Yes → S6). When the first control unit 21 receives the end signal from the smartphone 23 (S26: Yes), it resets the settings of the application sensor (S27).

[0060] As shown in Fig. 2(b), when the user sits within the second range R2 of the seat body 11, the application sensors are set by the second control unit 22, and the application sensors are not set or an error signal is not output by the first control unit 21. Note that the example in Fig. 2(b) shows an example in which pressure values ​​equal to or greater than a predetermined value are output from the five first sensors P1 to the second control unit 22, but even in this case, the second control unit 22 determines Yes in step S22 and executes the process of setting the application sensors (S23, S24).

[0061] 2(c), when the user sits across the first range R1 and the second range R2, pressure values ​​equal to or greater than a predetermined value are output from two first sensors P1 within the first range R1 to the first control unit 21, and pressure values ​​equal to or greater than a predetermined value are output from three first sensors P1 within the second range R2 to the second control unit 22. In this case, when the user launches the app, both the first control unit 21 and the second control unit 22 determine S22: No → S28: No, and output an error signal to the smartphone 23 (S29).

[0062] When the smartphone 23 receives an error signal from the first control unit 21 or the second control unit 22 (S7: Yes), it outputs an instruction to encourage the user to reseat (S8). The instruction to encourage the user to reseat can be, for example, a message such as "Do not sit in the center of the seat." When the user who has received the instruction to reseat moves his / her body and reseats within the first range R1 of the seat main body 11, the first control unit 21 sets the application sensor. When the user who has received the instruction to reseat moves his / her body and reseats within the second range R2 of the seat main body 11, the second control unit 22 sets the application sensor.

[0063] As described above, the following effects can be obtained in this embodiment. Since the application sensor is set according to the user's seating position in the seat body 11 that is long in the left-right direction, in a seat system 1 that has a seat body 11 that is long in the left-right direction, it is possible to prevent the user's seating location from being extremely restricted, while also preventing the smartphone 23 from being unable to obtain information from the pressure sensor P and being unable to execute the application.

[0064] Since the pressure sensor P is used as the sensor, the control unit 20 can execute an application such as a 100m sprint game that operates based on changes in pressure applied to the pressure sensor P by the user.

[0065] By providing multiple first sensors P1 lined up in the left-right direction and multiple second sensors P2 arranged in front of the first sensors P1 and lined up in the left-right direction, the number of types of user actions that can be distinguished by the smartphone 23 can be increased, and various apps can be executed on the smartphone 23.

[0066] The two first sensors P1 with the strongest response among the plurality of first sensors P1 and the two second sensors P2 with the strongest response among the plurality of second sensors P2 are set as sensors for the application, so that the optimum pressure sensor P can be set as a sensor for the application.

[0067] The control unit may also have a first control unit connected to the first sensor and the second sensor located within a first range in the left-right direction, and a second control unit connected to the first sensor and the second sensor located within a second range in the left-right direction that is different from the first range, and the first control unit and the second control unit may output an instruction to encourage the user to sit back down if the number of first sensors whose response strength is greater than or equal to a predetermined value is less than two.

[0068] Since the pressure sensors P are identified by two control units, namely, the first control unit 21 and the second control unit 22, the processing load on one control unit can be reduced. Also, if the number of first sensors P1 whose response strength is equal to or greater than a predetermined value is less than the standard number, it is highly likely that the user is not sitting in an appropriate position. In this case, by outputting an instruction to prompt the user to reseat, the application sensor can be reliably set by either the first control unit 21 or the second control unit 22.

[0069] 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, the same reference numerals are used to designate components and processes that are substantially the same as those in the above-described embodiment, and the description thereof will be omitted.

[0070] The method for setting the application sensors is not limited to the method described in the above embodiment. For example, the two first sensors P1 with the strongest responses among the plurality of first sensors P1 and the second sensors P2 arranged in the front-to-rear direction with respect to each of the two first sensors P1 with the strongest responses may be set as the application sensors.

[0071] Specifically, as shown in Fig. 5, a new process of step S44 may be provided instead of step S24 in the process of Fig. 4. Then, in step S44, the smartphone 23 sets, as application sensors, two second sensors P2 located in front of the two first sensors P1 set as application sensors.

[0072] According to this embodiment, a signal from the second sensor P2 is not required when setting the application sensor, which simplifies the processing in the smartphone 23. Also, in this embodiment, the application sensor is set for the rear first sensor P1, which is more likely to receive pressure from the user than the front second sensor P2, and then the application sensor is set for the second sensor P2. Therefore, compared to a method in which the application sensor is set for the second sensor P2 and then the application sensor is set for the first sensor P1, for example, the two pressure sensors P with the strongest response can be more reliably selected.

[0073] As another method for setting the application sensor, the control unit 20 may store in advance basic patterns of combinations of two first sensors P1 and two second sensors P2, and set the application sensor based on the pressure value from one pressure sensor P that has the strongest response among the multiple pressure sensors P. Specifically, the control unit 20 stores, for example, a basic pattern of combinations of four pressure sensors P as shown by hatching with dots in FIG. 2(a). In more detail, the control unit 20 stores a basic pattern of combinations of a first sensor P1, a first sensor P1 shifted two pitches to the left from the first sensor P1, and two second sensors P2 located in front of the two first sensors P1.

[0074] The control unit 20 first identifies multiple pressure sensors P whose pressure values ​​are equal to or greater than a predetermined value. In the example of FIG. 2(a), the pressure sensors P whose pressure values ​​are equal to or greater than the predetermined value are eight pressure sensors P that are within the two-dot chain line that indicates the outline of the user's body. In this case, the pressure sensors P that may fit the basic pattern are the four pressure sensors P indicated by dotted hatching and the four pressure sensors P without dotted hatching.

[0075] If the pressure sensor P with the strongest response is any of the four pressure sensors P indicated by dotted hatching, the control unit 20 sets the four pressure sensors P indicated by dotted hatching as the application sensors. If the pressure sensor P with the strongest response is any of the four pressure sensors P without dotted hatching, the control unit 20 sets the four pressure sensors P without dotted hatching as the application sensors.

[0076] When such a basic pattern is stored, a mark located at the center of the basic pattern may be provided on the seat surface of the seat body 11. In this case, the number of sensors can be reduced.

[0077] The arrangement of the pressure sensors P is not limited to that of the above embodiment. For example, as shown in Fig. 6, a third sensor P3 may be provided between the first sensor P1 and the second sensor P2 in the front-rear direction. In this case, the two most responsive first sensors P1, the two most responsive second sensors P2, and the two most responsive third sensors P3 may be set as application sensors.

[0078] 7(a), the third sensor P3 shown in FIG. 6 may be positioned laterally offset from the first sensor P1 and the second sensor P2. Also, as shown in FIGS. 7(a) and 7(b), pressure sensors P with different placement patterns may be set as application sensors depending on the type of application being used. Specifically, for example, when executing a 100m sprint game application, the control unit 20 sets the five pressure sensors P indicated by dotted hatching in FIG. 7(a) as application sensors. Also, for example, when executing a game application in which a character on the screen 23A moves up, down, left, and right, the control unit 20 sets the four pressure sensors P indicated by dotted hatching in FIG. 7(b) as application sensors.
