The first control device 200, the second control device 300, and the smartphone SP have CPUs, ROMs, RAMs, rewritable non-volatile memories, etc. (not shown), and execute pre-stored programs. Note that the smartphone SP further includes a display DSP.

The smartphone SP can communicate with the child seat 2 and the cart-attached chair 3 . Specifically, the smartphone SP acquires pressure values from the pressure sensors PS1 to PS3 via the first control device 200, and acquires pressure values from the pressure sensors PS4 to PS6 via the second control device 300. are doing. The smartphone SP is installed with a seat application for providing the seated person P with a game that can be executed based on signals (pressure values) transmitted from the child seat 2 and the cart-equipped chair 3 .

In the seat application according to the present embodiment, it is possible to provide the seated person P with a 100m run 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 child seat 2 or the chair 3 attached to the cart.

As shown in FIG. 3 , the smartphone SP includes a motion detection unit 110 , a game processing unit 120 , a step count calculation unit 130 , a data storage unit 140 and a notification unit 150 .

The motion detection unit 110 has a function of acquiring pressure values that change according to the motion of the seated person P from the child seat 2 and the cart-attached chair 3 . When the pressure value is acquired from the child seat 2 or the cart-attached chair 3 , the motion detection unit 110 outputs the acquired pressure value to the game processing unit 120 and the number of steps calculation unit 130 .

The game processing unit 120 has a function of executing a 100m run game based on the pressure value. For example, when a seated person P sitting in the child seat 2 runs a 100m running game, the game processing unit 120 acquires the pressure values P3 _R and P3 _L of the left and right pressure sensors PS3 in the child seat 2 . 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. 4, for example. In FIG. 4, 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. 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). , the previous value P3(n-1) at this time can be taken as the peak value Pm.

When the game processing unit 120 detects the peaks of the pressure values P3 _R and P3 _L according to the motion of the seated person P, the game processing unit 120 calculates the peak value Pm, and raises the leg based on the peak value Pm and the normal pressure P3 _n . A step strength F (F _R , _FL ) is calculated. The step strength F can be a value 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 game processing unit 120 calculates the step strength F during the 100-meter run game, the game processing unit 120 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. Note that the game processing unit 120 performs the same processing as described above when acquiring the pressure value from the cart-attached chair 3 . In the following description, the pressure value obtained from the child seat 2 is also referred to as "first pressure value", and the pressure value obtained from the cart-equipped chair 3 is also referred to as "second pressure value".

Returning to FIG. 3, the number-of-steps calculation unit 130 can calculate, as a first evaluation value, the first number of steps, which is the exercise amount of the seated person P sitting in the child seat 2, based on the first pressure value. Based on the pressure value, the second number of steps, which is the exercise amount of the seated person P sitting on the cart-attached chair 3, can be calculated as the second evaluation value. Specifically, for example, the number-of-steps calculation unit 130 measures the number of peak values Pm calculated by the game processing unit 120, and acquires this number as the number of steps. The number-of-steps calculation unit 130 outputs the measured number of steps to the data storage unit 140 .

The data accumulation unit 140 has a function of accumulating the first number of steps and the second number of steps output from the number-of-steps calculation unit 130 as integrated data. Specifically, the step count calculator 130 integrates the first step count and the second step count. Also, in this embodiment, the number of steps accumulated in the data accumulation unit 140 is updated every day. That is, in this embodiment, the total number of steps for one day is accumulated in the data accumulation unit 140 .

The notification unit 150 has a function of notifying the seated person P of the data accumulated in the data accumulation unit 140 . Specifically, in this embodiment, the notification unit 150 displays the total number of steps accumulated in the data accumulation unit 140 on the display DSP. Note that the method of notification by the notification unit 150 is not limited to this, and may be notified by voice, for example.

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 processing shown in FIG. 5 (START). In this control, the smartphone SP first determines whether or not it is in a state of being able to communicate with the child seat 2 or the cart-equipped chair 3 (S11).

If it is determined that communication is not possible in step S11 (No), the smartphone SP ends this process. When it is determined that communication is possible in step S11 (Yes), the smartphone SP displays the start screen (see FIG. 6) of the 100m run game on the display DSP (S12).

After step S12, the smart phone SP determines whether or not the 100m run game has been selected (S13). When it is determined that the 100m run game has been selected in step S13 (Yes), the smartphone SP executes the 100m run game (S14).

After step S14, specifically during the 100m run game, the smartphone SP calculates the number of steps based on the pressure value (S15). After step S15, more specifically, after the 100-meter run game ends, the smartphone SP adds (integrates) the current number of steps to the past number of steps accumulated in the data accumulation unit 140 (S16).

After step S16, the smartphone SP displays the integrated number of steps on the display DSP (S17). After step S17, the smartphone SP determines whether or not termination of the sheet application has been selected (S18).

If it is determined in step S18 that termination of the sheet application has not been selected (No), the smartphone SP returns to the process of step S12. If it is determined in step S18 that termination of the sheet application has been selected (Yes), the smartphone SP terminates this process.

Next, an example of specific operations of the smartphone SP will be described in detail.
As shown in FIG. 1, for example, when a person P (child) sitting in the child seat 2 starts a seat application on the smartphone SP to kill time while heading to a supermarket in a vehicle CR, the process of FIG. 5 is started. be. When the smartphone SP can communicate with the child seat 2 (S11: Yes), as shown in FIG. 6, the start screen of the 100m run game is displayed on the display DSP of the smartphone SP (S12).

On the start screen, a button B1 for starting the 100m run game and a button B2 for ending the seat application are displayed. When the seated person P selects the button B1, a determination of Yes is made in step S13, and the 100m run game is executed (S14).

When the 100m run game ends, the smartphone SP calculates the number of steps for one game and accumulates it in the data accumulation unit 140 (S15, S16), and also calculates the total number accumulated in the data accumulation unit 140 for the current day. is displayed on the display DSP (S17, see FIG. 7). When the seated person P executes the 100m run game a plurality of times in the vehicle, the number of steps for one game is sequentially accumulated in the data accumulation unit 140 each time the game ends.

When the vehicle CR arrives at the supermarket and the seated person P selects the end button B2 on the start screen shown in FIG. 6, the smartphone SP ends the seat application. When the seated person P seated on the cart-attached chair 3 of the shopping cart SHC while shopping at the supermarket activates the seat application of the smartphone SP again to kill time, the process of FIG. 5 is started again.

When the smartphone SP is in a state of being able to communicate with the cart-attached chair 3 (S11: Yes), as shown in FIG. ). Thereafter, as described above, the number of steps for one game is sequentially accumulated in the data accumulation unit 140 each time the seated person P executes the game. Therefore, the seated person P can know the total number of steps in which the number of steps in the vehicle CR and the number of steps in the shopping cart SHC are added, so that how much the seated person P has exercised can be easily known. be able to. In addition, since the parent of the seated person P can also know the number of steps (exercise amount) of the child for one day, the child's subsequent activity plan, meal menu, etc. can be determined in consideration of the exercise amount. .

As described above, according to the seat system 1 of the present embodiment, the following effects can be obtained.
In an environment where seats (2, 3) having pressure sensors are installed in various places, a seated person P sitting on a given seat can use information obtained from other seats.

Having the data storage unit 140 in the smartphone SP eliminates the need for a server, which will be described later, so that the configuration of the seat system 1 can be simplified.

Since the number of steps, which is the amount of exercise of the seated person P, is used as an evaluation value, the number of steps integrated by the seated person P can be referred to, and the physical condition of the seated person P can be grasped.

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 addition, in the following description, the same reference numerals are given to the structures substantially similar to those of the above-described embodiment, and the description thereof is omitted.

In the above embodiment, the data storage unit 140 is provided in the smartphone SP, but the present invention is not limited to this. For example, as shown in FIGS. may be provided. Specifically, in the form shown in FIG. 8, the seat system 1A includes a server SV in addition to the child seat 2, the cart-attached chair 3, and the smartphone SP described above.

As shown in FIG. 9, the smartphone SP includes a transmission section 160 and a reception section 170 instead of the data storage section 140 in the above embodiment. The transmission unit 160 has a function of associating the number of steps for one game calculated by the number-of-steps calculation unit 130 with the identification information corresponding to the seated person P and transmitting the information to the server SV. The receiving unit 170 has a function of receiving the later-described total number of steps transmitted from the server SV and outputting the received total number of steps to the notification unit 150 . Thereby, the smart phone SP is configured to acquire the data integrated by the server SV (the total number of steps) from the server SV and notify the seated person P of the acquired data.

The server SV includes a receiver 410 , a data storage 420 and a transmitter 430 . The receiving unit 410 has a function of receiving the number of steps associated with the identification information from the smart phone SP. Upon receiving the number of steps associated with the identification information, receiving section 410 outputs the received number of steps to data storage section 420 together with the identification information.

The data accumulation unit 420 has a function of accumulating and accumulating the number of steps acquired from the reception unit 410 for each identification information. The transmission unit 430 has a function of transmitting the total number of steps corresponding to the seated person P accumulated in the data accumulation unit 420 to the smart phone SP.

In this form, the smartphone SP is configured to execute the processing shown in FIG. 10, and the server SV is configured to execute the processing shown in FIG. The process shown in FIG. 10 has new steps S31 and S32 instead of step S16 in the process shown in FIG. 5, and other processes are the same as those in FIG.

In the process shown in FIG. 10, the smartphone SP calculates the number of steps in step S15, and then transmits the calculated number of steps to the server SV (S31). After step S31, the smartphone SP requests and acquires the total number of steps as integrated data from the server SV (S32), and displays the acquired total number of steps on the display DSP (S17).

As shown in FIG. 11, the server SV constantly determines whether or not the number of steps has been acquired from the smartphone SP (S41). If it is determined in step S41 that it has not been acquired (No), the server SV terminates this process.

If it is determined that the number of steps has been acquired in step S41 (Yes), the server SV adds (integrates) the acquired number of steps to the past number of steps accumulated in the data accumulation unit 420 (S42). After step S42, the server SV determines whether there is a request for integrated data, that is, the total number of steps from the smartphone SP (S43).

If it is determined that there is no request in step S43 (No), the server SV terminates this process. If it is determined that there is a request in step S43 (Yes), the server SV transmits the integrated total number of steps to the smart phone SP (S43), and ends this process.

As described above, according to this embodiment, it is not necessary to provide a data storage unit in the smartphone SP, so the storage capacity of the smartphone SP can be saved.

Since the total number of steps integrated by the server SV is notified to the seated person P via the smartphone SP, the seated person P can effectively utilize the total number of steps.

In the above embodiment, only the total number of steps as integrated data is displayed on the display DSP, but the present invention is not limited to this, and integrated data can be used for various purposes. For example, an activity plan may be determined based on the total number of steps taken.

Specifically, the smartphone SP may be configured to execute the process shown in FIG. 12 in the seat system 1 shown in FIG. 1, for example. The process shown in FIG. 12 has a new step S51 in place of step S17 in the process shown in FIG. 5, and the rest of the process is the same as the process in FIG.

In the process shown in FIG. 12, the smartphone SP integrates and stores the number of steps in the data storage unit 140 (S16), determines an activity plan based on the integrated total number of steps, and displays the determined activity plan. Display on the DSP (S51). Here, in this form, a 100-meter run game and rest (end of sheet application) are exemplified as activity plans.

In step S51, when the total number of steps is less than a predetermined number of steps (for example, 3000 steps), the amount of exercise of the seated person P is insufficient. Presented as a recommended action plan. Specifically, as shown in FIG. 13, the smartphone SP displays on the display DSP a message prompting execution of the 100m run game, and pushes the button B1 for executing the 100m game from the button B2 for resting. is also displayed large.

In step S51, when the total number of steps is equal to or greater than a predetermined number of steps, the smartphone SP recommends taking a break, that is, ending the seat application, because the seated person P tends to exercise (game) too much. present as a plan. Specifically, as shown in FIG. 14, the smartphone SP displays a message prompting a break on the display DSP, and displays a button B2 for taking a break larger than the button B1 for executing the 100m game. .

According to this form, since an activity plan is presented to the seated person P based on the total number of steps (integrated data), an activity plan suitable for the physical condition of the seated person P can be presented to the seated person P. can. Also, when the parent of the seated person P sees the screen shown in FIG. 14, he/she can know that the child is overdoing the exercise (game), so he/she can take the smart phone SP away from the child.

In the above-described embodiment, the evaluation value (first evaluation value, second evaluation value) of the physical condition of the seated person P is the exercise amount (step count) of the seated person P. However, the present invention is not limited to this, and the evaluation value may be, for example, body weight or sitting time. For example, when the evaluation value is body weight, the smartphone SP can be configured to execute an application for measuring body weight, specifically the process shown in FIG. 15, in the seat system 1 shown in FIG.

The process shown in FIG. 15 has step S11 of the process shown in FIG. 5, and new steps S61 to S67. In the process shown in FIG. 15, when the smartphone SP determines that communication is possible in step S11 (Yes), it acquires the pressure value from the child seat 2 or the cart-equipped chair 3 (S61).

After step S61, the smartphone SP calculates the weight of the seated person P based on the pressure value (S62). After step S62, the smartphone SP updates the weight history accumulated in the data accumulation unit 140 (S63). Specifically, in step S<b>63 , the smartphone SP associates the weight calculated this time with the date, and accumulates it in the data accumulation unit 140 together with the weight and date data in the past. In other words, the smartphone SP integrates data by accumulating weight and date data instead of integrating data by adding the number of steps as in the above embodiment.

After step S63, the smartphone SP determines whether the application is active (S64). If it is determined in step S64 that it is in the active state (Yes), the smartphone SP, as shown in FIG. This month's weight history is displayed (S65).

If it is determined in step S64 that it is not in the active state (No), the smartphone SP notifies the body weight calculated this time in a message frame displayed on a part of the home screen as shown in FIG. 17 (S66). . After step S65 or step S66, the smartphone SP determines whether termination of the application has been selected (S67).

When it is determined that end is not selected in step S67 (No), the smartphone SP returns to the process of step S61. If it is determined that end is selected in step S67 (Yes), the smartphone SP ends this process.

According to this form, the seated person P can know the weight history (integrated data), so that the seated person P can easily manage the weight.

When the evaluation value is the sitting time, for example, advertisements, recommended applications, health advice, etc. can be presented to the seated person P based on the sitting time. For example, if the sitting time is longer than a predetermined time, it can be determined that the person is thirsty, and an advertisement for beverages can be presented to the seated person P. Note that the seating time may be calculated as the elapsed time after the pressure value becomes equal to or greater than a predetermined threshold value.

In the above-described embodiment, the pressure value was exemplified as the first information and the second information for detecting the physical condition of the seated person, but the present invention is not limited to this, and the first information and the second information are, for example, It may be a current value corresponding to the body temperature or the amount of perspiration.
