An embodiment of the present invention will be described below with reference to the drawings.
As shown in FIG. 1, the seat system 1 includes a vehicle seat S as an example of a seat, a wearable device W, and a smartphone SP as an example of a terminal.

The vehicle seat S is configured, for example, as a vehicle seat installed in a vehicle. In the present invention, front and rear, left and right, and up and down are based on the seated person P sitting on the vehicle seat S. As shown in FIG.

As shown in FIG. 2, the vehicle seat S includes a seat body S0 and a control device 100. As shown in FIG. The seat body S0 has a seat cushion S1 and a seat back S2. The seat cushion S1 and the seat back S2 include a cushion pad 20 and an outer skin 10 covering the cushion pad 20. As shown in FIG. The cushion pad 20 is made of urethane foam or the like and supported by a frame (not shown). The skin 10 is made of synthetic leather, fabric, or the like.

A plurality of pressure sensors PS1 to PS6 are provided under the skin 10 of the seat cushion S1 and the seat back S2. The pressure sensors PS1 to PS6 are examples of first sensors, and acquire measured values as first information for detecting the motion of the seated person P sitting on the seat body S0. The pressure sensors PS1 to PS6 are arranged so as to be able to detect the state of the seat surface facing the seated person P seated on the seat body S0, and acquire pressure values from the seated person P sitting on the seat body S0.

Each pair of pressure sensors PS1 to PS6 are provided symmetrically with respect to the center of the vehicle seat S in the left and right direction.
Specifically, the seat cushion S1 is provided with pressure sensors PS1 to PS3. The pressure sensor PS1 and the pressure sensor PS2 are arranged at positions corresponding to the buttocks of the seated person P on the seat cushion S1. The pressure sensor PS1 and the pressure sensor PS2 constitute a first cushion sensor SC1 that measures the pressure from the seated person P's buttocks. The pressure sensor PS2 is arranged slightly before the pressure sensor PS1. Note that the first cushion sensor SC1 may include only one of the pressure sensor PS1 and the pressure sensor PS2.

The pressure sensor PS3 is located under the seated person P's thighs. The pressure sensor PS3 constitutes a second cushion sensor SC2 that measures the pressure value from the thighs of the seated person P. The pressure sensor PS3 is located far forward from the pressure sensors PS1 and PS2.

The seat back S2 is provided with pressure sensors PS4 to PS6. The pressure sensor PS4 is provided at a position corresponding to the back of the seated person P's waist. Pressure sensor PS5 is positioned slightly above pressure sensor PS4. Both the pressure sensor PS4 and the pressure sensor PS5 constitute a first back sensor SB1 that measures the pressure from the seated person P's waist. Note that the first back sensor SB1 may include only one of the pressure sensor PS4 and the pressure sensor PS5.

The pressure sensor PS6 is arranged at a large distance above the pressure sensors PS4 and PS5. The pressure sensor PS6 is positioned corresponding to the upper part of the seated person P's back. The pressure sensor PS6 constitutes a second back sensor SB2 that measures the pressure value from the seated person P's shoulder blades.

Note that the pressure sensors PS1 to PS6 are, for example, elements whose electrical resistance changes according to external pressure, and the higher the pressure value, the higher (or lower) the voltage of the detection signal.

A paint 31 is applied to the outer surface of the skin 10 at positions corresponding to the respective pressure sensors PS1 to PS6. The paint 31 is exposed to the outside of the skin 10 by being applied to the outer surface of the skin 10 . The color of the paint 31 is different from the color of the outer surface of the skin 10.例文帳に追加Specifically, for example, when the outer surface of the skin 10 is black, the color of the paint 31 can be a color such as yellow that stands out against black.

Such paint 31 displays the positions of the pressure sensors PS1 to PS6 so as to be visible from the outside of the seat body S0 before the seated person P sits on the vehicle seat S. As shown in FIG.

The control device 100 is connected to the pressure sensors PS1-PS6 so that pressure values can be obtained from the pressure sensors PS1-PS6. The control device 100 can transmit information detected by each of the pressure sensors PS1 to PS6 to the smart phone SP.

Specifically, the controller 100 is connected to a short-range communication device 3A that enables short-range wireless communication such as Bluetooth (registered trademark) or Wi-Fi (registered trademark). The control device 100 can communicate with the smartphone SP via the short-range communication device 3A.

The control device 100, the smartphone SP, and the wearable device W have a CPU, ROM, RAM, and rewritable nonvolatile memory (not shown), and execute pre-stored programs. Note that the smartphone SP further includes a display DSP.

The wearable device W is a watch-type device worn on the arm of the seated person P, and further includes a display W1 and an acceleration sensor W2. The wearable device W has, for example, a function of acquiring the number of steps of the seated person P based on acceleration acquired by the acceleration sensor W2, and a function of transmitting the number of steps of the seated person P to the smartphone SP.

Here, the second sensor according to the present embodiment is composed of the acceleration sensor W2 and a step number conversion unit (control unit configured by the aforementioned CPU or the like) that converts the acceleration into the number of steps. The second sensor according to the present embodiment acquires the number of steps of the seated person P as an example of the second information for detecting the physical condition of the seated person P.

The smartphone SP acquires pressure values from the pressure sensors PS1 to PS6 via the control device 100, and from the wearable device W for a predetermined time in the past, for example, for one hour (from one hour before the present to the present It has a function to acquire the number of steps during A seat application for providing the seated person P with a game that can be executed based on a signal (pressure value) transmitted from the vehicle seat S is installed in the smartphone SP.

In the seat application according to the present embodiment, it is possible to provide the seated person P with a 100m run game and a Zen meditation game. The 100m run game is a game in which a character displayed on the display DSP runs based on the pressure value transmitted from the vehicle seat S.

Specifically, the smartphone SP acquires the pressure values P3 _R and P3 _L of the left and right pressure sensors PS3 in the vehicle seat S when executing the 100m run game. Then, the normal pressure _P3n , which is the average pressure of the seated person P sitting at that time, and the threshold value P3th for detecting the peak of the pressure value are determined, and the average leg of the seated person P is determined. A normal step period TS _n is calculated.

Specifically, when the seated person P lifts his/her legs alternately, the pressure values P3 _R and P3 _L change as shown in FIG. 3, for example. In FIG. 3, the portion where the pressure suddenly decreases indicates that the pressure at the pressure sensor PS3 is decreased due to the seated person P raising his or her leg. That is, the pressure value around 140 where the pressure does not decrease becomes the average normal pressure _P3n when the leg is not raised. To calculate the normal pressure P3 _n , for example, the difference between the previous value and the current value of the pressure values P3 _R and P3 _L (the value obtained by subtracting the previous value P3(n−1) from the current value P3(n)) is used. ) is less than or equal to a predetermined value (that is, when the change in value is small), the current values may be counted and averaged.

The threshold value P3th is a threshold value for determining that the leg is being raised. For example, in the case of FIG. 3, a value of about 100 to 120 may be used. Therefore, a value obtained by multiplying the normal pressure _P3n by a predetermined value can be used as the threshold value P3th. For example, a value obtained by multiplying the normal pressure _P3n by a predetermined value of about 0.6 to 0.9 can be set as the threshold value P3th.

The normal step period _TSn is the average value of the step period TS, which is the time interval between the peaks of the pressure values _P3R and _P3L .
The pressure values P3 _R and P3 _L change from negative to positive under the condition that each of the pressure values P3 _R and P3 _L is smaller than the threshold value P3th (exceeds from the upper side to the lower side). , and the previous value P3(n-1) at this time can be set as the peak value Pm.

When the smartphone SP detects the peaks of the pressure values P3 _R and P3 _L according to the motion of the seated person P, the smartphone SP calculates the peak value Pm, and based on the peak value Pm and the normal pressure P3 _n , the height of the leg raised. A step strength F(F _R , _FL ) is calculated. The step strength F can be obtained by subtracting the peak value Pm from the magnitude of the peak, that is, the normal pressure _P3n . In this embodiment, in order to eliminate differences due to the size of the physique of the seated person P, the value is normalized by the normal pressure _P3n . For example, the step strength F is
F=( _P3n -Pm)/ _P3n
and

When the smartphone SP calculates the step strength F during the 100m run game, it moves the character on the display DSP toward the goal. The amount of movement at this time corresponds to the magnitude of the step strength F. FIG. The smartphone SP moves the character toward the goal by F[m], for example.

In addition, the smartphone SP calculates the number of steps as an example of the amount of activity of the seated person P during the 100m run game. Specifically, for example, the number of peak values Pm calculated during a 100m game can be used as the number of steps.

When the 100m game ends, the smartphone SP displays the calculated number of steps on the display DSP. Further, the smart phone SP transmits the calculated number of steps to the wearable device W when it is in a state capable of communicating with the wearable device W at the end of the 100m game.

The wearable device W has a function of adding the number of steps transmitted from the smartphone SP to the number of steps measured by the wearable device W. As a result, the result of the exercise of the seated person P on the vehicle seat S can be reflected in the wearable device W, so that the exercise amount of the seated person can be accurately managed.

The zazen game is a game for having the seated person P sit on the vehicle seat S and do zazen. In the Zen meditation game, the seated person P is placed so that the pressure applied to the left side of the seat cushion S1 and the pressure applied to the right side substantially match, and the pressure applied to the front side and the pressure applied to the rear side of the seat cushion S1 substantially match. It can be configured as a game that encourages the posture of

Specifically, for example, the meditation game can be configured as a game in which a cursor that moves as the center of gravity of the seated person P moves is aligned with a target displayed on the display DSP. Specifically, in the xy coordinate system displayed on the display DSP, when the position of the center of the target is (X0, Y0), the cursor position is changed to (Xn, Yn) so as to satisfy the following equation. You can set it.

Xn=X0-((P1 _R +P2 _R +P3 _R )/3-(P1 _L +P2 _L +P3 _L )/3)
Yn=Y0-((P1 _R +P1 _L +P2 _R +P2 _L )/4-(P2 _R +P2 _L +P3 _R +P3 _L )/4)
P1 _R : pressure value of right pressure sensor PS1 P1 _L : pressure value of left pressure sensor PS1 P2 _R : pressure value of right pressure sensor PS2 P2 _L : pressure value of left pressure sensor PS2 P3 _R : right pressure Pressure value P3 _L of sensor PS3: Pressure value of left pressure sensor PS3

In the zazen game, the closer the position of the cursor to the center of the target (X0, Y0), the better the zazen is performed. . In the zazen game, the result of zazen is displayed according to the percentage of the judgment value during a predetermined period of time. For example, if the ratio of the GOOD judgment value for a predetermined period of time is 90% or more, the characters "GOOD" are displayed as a result indicating that Zen meditation at the level of a monk has been performed. In addition, when the ratio of the GOOD judgment value during the predetermined time is less than 70%, the characters "BAD" are displayed as a result indicating that the zazen is completely unsuccessful. In other cases, the characters "NORMAL" are displayed as a result indicating that the zazen at the ordinary person's level has been performed.

The smartphone SP acquires the number of steps in the past hour from the wearable device W on the condition that the seat application described above is started, and based on the acquired number of steps, the activity using the pressure sensors PS1 to PS3 is performed. It has a function of presenting the plan to the seated person P. Here, in the present embodiment, as shown in FIG. 4, a 100-meter run game, a Zen meditation game, and a break (end of the seat application) are exemplified as activity plans.

The smartphone SP determines a plan to be presented to the seated person P by comparing the number of steps during the past hour with specific reference values (3000, 5000) shown in FIG. Specifically, when the number of steps in the past hour is less than 3000, the smartphone SP presents an activity plan for promoting exercise, that is, a 100m run game, because the amount of exercise of the seated person P is insufficient. do.

Further, when the number of steps in the past hour is 3000 steps or more and less than 5000 steps, the smartphone SP has a sufficient exercise amount of the seated person P, so the smartphone SP plans an activity that can be enjoyed with a relatively small amount of exercise. Present a Zen meditation game. In addition, when the number of steps in the past hour is 5000 or more, the smartphone SP presents an activity plan for the seated person P to take a break, that is, to end the seat application, because the seated person P tends to exercise too much. do.

Further, the smartphone SP determines whether or not the seated person P is seated on the seat body S0 based on the pressure values obtained from the pressure sensors PS1 to PS3. It is configured to present the plan to the person P. Further, when the seated person P executes the plan, for example, when the 100m run game is executed, the smartphone SP calculates the number of steps in the 100m run game based on the pressure value, and calculates the number during the 100m run game. Based on the number of steps and the number of steps obtained from the wearable device W, the plan is determined again and the determined plan is presented.

Next, the operation of the smart phone SP (specifically, the control unit within the smart phone SP) will be described in detail.
When the seated person P starts up the seat application, the smartphone SP starts the control shown in FIG. 5 (START). In this control, the smartphone SP first determines whether or not it is in a state capable of communicating with the control device 100 of the vehicle seat S (S11).

If it is determined that communication is not possible in step S11 (No), the smartphone SP ends this control. When it is determined that communication is possible in step S11 (Yes), the smart phone SP determines whether communication with the wearable device W is possible (S12).

When it is determined that communication is possible in step S12 (Yes), the smartphone SP sets the flag FL indicating that communication with the wearable device W is possible to 1 (S13). The number of steps during the time is obtained and stored (S14).

When it is determined that communication is not possible in step S12 (No), the smartphone SP sets the flag FL to 0 (S15). After step S14 or step S15, the smartphone SP determines an activity plan based on the number of steps in the past hour and the table shown in FIG. 4 (S16).

Specifically, when step S16 is executed first after starting the seat application, the smartphone SP determines an activity plan based on the number of steps acquired from the wearable device W in the past hour. Further, when the smartphone SP executes step S16 after executing a 100m run game or a Zen meditation game, which will be described later, the number of steps stored and the number of steps obtained in the 100m run game or the execution time of the Zen meditation game Based on , the number of steps in the past hour is recalculated, and the activity plan is determined again.

Specifically, when executing step S16 after executing the 100-meter run game, the smartphone SP corresponds to the time corresponding to the execution time of the 100-meter run game based on the number of steps stored in the past hour. By adding the number of steps obtained in the 100-meter run game to the deleted number of steps, the number of steps for the past hour is updated. Further, when executing step S16 after executing the zazen game, the smartphone SP calculates the number of steps corresponding to the execution time of the zazen game from the stored number of steps for the past hour. Decrease to update the number of steps during the past hour.

After step S16, the smartphone SP determines whether or not the person P is seated on the vehicle seat S based on the pressure value transmitted from the vehicle seat S (S17). When it is determined that the person is not seated in step S17 (No), the smartphone SP displays on the display DSP a display prompting the seated person P to sit on the vehicle seat S (see FIG. 6) (S18). .

When it is determined that the user is seated in step S17 (Yes), the smartphone SP displays a game selection screen (see FIG. 7) for selecting a game on the display DSP (S19). At this time, the smartphone SP displays the plan determined in step S15 on the game selection screen, and displays the button for selecting the determined plan larger than the other buttons.

After step S19, the smart phone SP determines whether or not the 100m run game has been selected (S20). If it is determined in step S20 that the 100m run game has been selected (Yes), the smartphone SP starts the 100m run game (S21).

After step S21, the smartphone SP calculates the number of steps based on the pressure value during the 100m run game (S22). After step S22, more specifically after the end of the 100m run game, the smartphone SP displays the result of the number of steps on the display DSP (S23).

After step S23, the smartphone SP determines whether or not the flag FL indicating that communication with the wearable device W is possible is 1 (S24). When it is determined that FL=1 in step S24 (Yes), the smart phone SP transmits the number of steps obtained in the 100m run game to the wearable device W (S25), and returns to the process of step S16. When it is determined that FL is not 1 in step S24 (No), the smartphone SP skips step S25 and returns to the process of step S16.

If it is determined in step S20 that the 100m run game has not been selected (No), the smartphone SP determines whether or not the Zen meditation game has been selected (S26). If it is determined in step S26 that the meditation game has been selected (Yes), the smartphone SP executes the meditation game (S27) and returns to the process of step S16.

If it is determined in step S26 that the Zen meditation game has not been selected (No), the smartphone SP determines whether or not termination of the seat application has been selected (S28). If it is determined in step S28 that termination of the sheet application has not been selected (No), the smartphone SP returns to the process of step S19. If it is determined in step S28 that termination of the sheet application has been selected (Yes), the smartphone SP terminates this control.

Next, an example of specific operations of the smartphone SP will be described in detail.
As shown in FIG. 1, a seated person P who has hardly exercised in the past hour operates a smartphone SP while each device (S, W, SP) constituting the seat system 1 is in a communicable state. When the seat application is started up, the processing of step S11: Yes→step S12: Yes→steps S13 and S14 is sequentially executed in the control shown in FIG.

In step S14, the number of steps less than 3000 steps is acquired by the smart phone SP because the seated person P has hardly exercised during the past hour. After that, the smart phone SP determines the activity plan to be the “100m run game” based on the number of steps less than 3000 steps and the table of FIG. 4 (S16). After step S16, the smartphone SP determines whether the seated person P is seated on the vehicle seat S based on the pressure value transmitted from the vehicle seat S (S17).

In step S17, when the occupant P is not seated on the vehicle seat S, as shown in FIG. A message prompting the user to take a seat is displayed (S18). When the seated person P sits on the vehicle seat S according to the message, it is determined as Yes in step S17, and the game selection screen shown in FIG. 7 is displayed (S19).

On the game selection screen at this time, since the activity plan determined in step S16 is "100m run game", a message such as "I recommend the 100m run game" prompting the seated person P to exercise is displayed. Along with this, a button B1 for starting the 100m run game is displayed in a larger size than the other buttons B2 and B3. When the seated person P selects the button B1, a determination of Yes is made in step S20, and the 100m run game is executed (S21-S23).

After the end of the 100m run game, the smartphone SP transmits the number of steps measured during the 100m run game to the wearable device W (S25), and returns to the process of step S16. When the seated person P runs the 100m run game several times and the number of steps in the past hour increases to 3000 steps or more, the smartphone SP determines the activity plan to be the "zazen game" in step S16. do.

When the activity plan is determined to be the meditation game, the smartphone SP displays a game selection screen as shown in FIG. 8 on the display DSP. At this time, on the game selection screen,
A message "We recommend the Zen meditation game" is displayed, and a button B2 for starting the Zen meditation game is displayed larger than the other buttons B1 and B3. When the seated person P selects the button B2, it is determined as Yes in step S26, and the meditation game is executed (S27).

When the seated person P executes the Zen meditation game several times and the number of steps in the past hour decreases to less than 3000 steps, the smartphone SP changes the activity plan to the "100m run game" again in step S16. decide. On the game selection screen shown in FIG. 8, the seated person P ignores the recommended plan and performs actions such as running a 100-meter run game several times. After that, the smartphone SP determines the activity plan to be "rest" in step S16.

When the activity plan is determined to be rest, the smartphone SP displays a game selection screen as shown in FIG. 9 on the display DSP. At this time, on the game selection screen,
A message "Take a break is recommended" is displayed, and a button B3 for taking a break, that is, ending the sheet application, is displayed larger than the other buttons B1 and B2. When the seated person P selects the button B3, a determination of Yes is made in step S28, and the seat application ends.

As described above, according to the seat system 1 of the present embodiment, the following effects can be obtained.
Based on the number of steps acquired from the wearable device W worn by the seated person P, the smartphone SP presents the seated person P with an activity plan using the pressure sensors PS1 to PS3. The seated person P can be presented with an activity plan suitable for biological information, activity information, and the like.

By adopting the pressure sensors PS1 to PS3 as the first sensors, it is possible to present the seated person P with an activity plan using the pressure sensors PS1 to PS3, more specifically, a plan that encourages the seated person P to exercise.

By presenting the plan to the seated person P on the condition that the seated person P is seated on the seat body S0, the plan is presented when the seated person P is in a state where the vehicle seat S can be used. Therefore, the seated person P can quickly select and execute the presented plan.

When the seated person P executes the 100-meter run game, the number of steps of the seated person P is calculated and displayed to the seated person P, so that it is possible to easily know how much the seated person P has exercised.

The activity plan is determined again based on the number of steps reflecting the execution result of the plan and the number of steps acquired from the wearable device W, and the plan is presented to the seated person P, so that the body of the seated person P at that time The seated person P can be presented with the plan most suitable for the state.

Since the smart phone SP transmits the number of steps calculated in the 100m running game to the wearable device W, the wearable device W can use the amount of activity (the number of steps) in the vehicle seat S, so that the wearable device W can obtain an accurate number of steps. can be stored.

Since the smart phone SP compares the number of steps with a specific reference value to determine the plan to be presented to the seated person P, an appropriate plan can be determined.

Although the embodiments of the present invention have been described above, the present invention can be modified as appropriate and implemented as shown in other forms below.

In the above-described embodiment, the seated person P is notified of the number of steps of the seated person P calculated in the 100m run game by displaying it on the display DSP, but the present invention is not limited to this.
