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 seated posture, which means they cannot be used very effectively.

Therefore, the present invention aims to provide a seat system that can provide advertising information appropriate to an occupant sitting in a seat equipped with a sensor, in order to propose new value for seats.

In order to solve the above-mentioned problems, the seat system of the present invention comprises a seat body, a seat having a sensor provided on the seat body for acquiring information for identifying the physical condition of an occupant sitting in the seat body, a server storing a plurality of pieces of advertising information, and a terminal capable of acquiring the information from the sensor and communicating with the server.
The terminal or the server selects advertising information related to the information or the evaluation value from the plurality of pieces of advertising information based on the information or the evaluation value based on the information, and notifies the seat occupant of the advertising information.

According to this configuration, advertising information is selected based on information acquired by a sensor installed in the seat body and notified to the seat occupant, so advertising information appropriate to the physical condition of the seat occupant sitting in a seat having a sensor can be provided.

The terminal may also include a location information acquisition unit that acquires location information of the sheet, and the terminal or the server may select advertising information related to the information or the evaluation value and the location information from the plurality of pieces of advertising information based on the information or the evaluation value and the location information.

In this way, in addition to information corresponding to the physical condition, location information is also referenced to select advertising information, making it possible to provide advertising information suited to the location of the seated occupant and the seated occupant's physical condition.

The terminal may also identify the location of the advertiser of the selected advertising information based on the selected advertising information, and report the advertising information on the condition that the location identified by the location information is within a predetermined area that includes the location of the advertiser.

This allows the occupant to be notified of advertising information that corresponds to their current location, enabling them to quickly move to the location where they can receive the goods or services presented in the advertising information and quickly receive the services, etc.

The sensor may be a pressure sensor, and the terminal may calculate an evaluation value related to exercise based on the pressure value as the information, and the terminal or the server may select advertising information based on the evaluation value.

By doing this, advertising information is selected based on the evaluation value related to exercise, so that facilities etc. that suit the seated person's level of exercise can be introduced to the seated person.

The terminal may also be capable of executing an exercise program that causes the seat occupant to exercise based on the pressure value from the pressure sensor, and may notify the seat occupant of selected advertising information on the condition that a specified exercise has been completed while the exercise program is being executed.

This allows the seated person to be notified of advertising information based on the results of the exercise program.

According to the present invention, advertising information is selected based on information acquired by a sensor installed in the seat body and is notified to the seat occupant, so advertising information suited to the physical condition of the seat occupant sitting in a seat having a sensor can be presented.

In addition to the information corresponding to the physical condition, by referring to the location information and selecting advertising information, it is possible to provide advertising information that is appropriate for the location of the seated occupant and the seated occupant's physical condition.

In addition, by providing advertising information on the condition that the location specified by the location information is within a specified range from the advertiser's location, the seated person can quickly move to the location where they can receive the goods or services presented in the advertising information, and can quickly receive the services, etc.

In addition, by selecting advertising information based on the exercise-related evaluation value, it is possible to introduce the seated person to facilities that suit the seated person's level of exercise.

In addition, by notifying the seated person of selected advertising information on the condition that a specified exercise has been completed while the exercise program is being performed, the seated person can be notified of advertising information according to the results of the exercise program.

Hereinafter, an embodiment of the present invention will be described 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 server SV, and a smartphone SP as an example of a terminal.

The vehicle seat S is configured, for example, as a vehicle seat that is installed in a vehicle. In the present invention, front, back, left, right, up and down are based on an occupant P sitting in the vehicle seat S.

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

The seat cushion S1 and the seat back S2 are provided with multiple pressure sensors PS1 to PS6 under the cover 10. The pressure sensors PS1 to PS6 are an example of a sensor, and acquire measured values that are information for identifying the physical condition of the seated occupant P sitting in the seat body S0. The pressure sensors PS1 to PS6 are positioned so that they can detect the condition of the seat surface facing the seated occupant P sitting in the seat body S0, and acquire pressure values from the seated occupant P sitting in the seat body S0.

The pressure sensors PS1 to PS6 are provided in pairs symmetrically on the left and right sides of the vehicle seat S with respect to the center of the vehicle seat S on the left and right sides.
Specifically, the seat cushion S1 is provided with pressure sensors PS1 to PS3. The pressure sensors PS1 and PS2 are disposed in positions on the seat cushion S1 corresponding to the buttocks of the seated occupant P. The pressure sensors PS1 and PS2 constitute a first cushion sensor SC1 that measures pressure from the buttocks of the seated occupant P. The pressure sensor PS2 is disposed slightly in front of the pressure sensor PS1. Note that the first cushion sensor SC1 may include only one of the pressure sensors PS1 and PS2.

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

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

Pressure sensor PS6 is positioned far above pressure sensors PS4 and PS5. Pressure sensor PS6 is located corresponding to the upper part of the back of seated occupant P. Pressure sensor PS6 constitutes a second back sensor SB2 that measures the pressure value from the shoulder blades of seated occupant P.

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

Paint 31, which serves as a position indicator, is applied to the outer surface of the skin 10 at positions corresponding to the pressure sensors PS1 to PS6. The paint 31 is applied to the outer surface of the skin 10 and is exposed to the outside of the skin 10. The color of the paint 31 is different from the color of the outer surface of the skin 10. Specifically, for example, if the outer surface of the skin 10 is black, the color of the paint 31 can be a color that stands out against the black, such as yellow.

This type of paint 31 visually indicates the positions of each pressure sensor PS1 to PS6 from the outside of the seat body S0 before the occupant P sits in the vehicle seat S.

The control device 100 is connected to the pressure sensors PS1 to PS6 so that it can acquire pressure values from each of the pressure sensors PS1 to PS6. The control device 100 can transmit information detected by each of the pressure sensors PS1 to PS6 to the smartphone SP.

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

The control device 100, smartphone SP, and server SV each have a CPU, ROM, RAM, rewritable non-volatile memory, etc. (not shown), and execute pre-stored programs. The smartphone SP further includes a display DSP and a location information acquisition unit 2.

The smartphone SP has a function of acquiring pressure values from each of the pressure sensors PS1 to PS6 via the control device 100. A seat app is installed on the smartphone SP to provide the seat occupant P with games that can be played based on signals (pressure values) transmitted from the vehicle seat S.

The seat app according to this embodiment is capable of providing a 100m sprint game to a seated person P. The 100m sprint game is a game in which a character displayed on the display DSP runs based on pressure values transmitted from the vehicle seat S. The 100m sprint game is an example of an exercise program that causes a seated person P in the vehicle seat S to exercise based on pressure values from pressure sensors PS1 to PS3.

In more detail, when the smartphone SP plays the 100m sprint game, it acquires the pressure values P3R and P3L of the left and right pressure sensors PS3 on the vehicle seat S. It then determines the normal pressure P3n, which is the average pressure of the seated occupant P sitting at that time, and the threshold value P3th for detecting the peak of the pressure value, and calculates the normal step period TSn, which is the period for moving the average legs of the seated occupant P.

Specifically, when seated person P alternately raises his/her legs, pressure values P3R, P3L change, for example, as shown in FIG. 3. In FIG. 3, the part where the pressure suddenly decreases indicates that the pressure at pressure sensor PS3 has decreased as a result of seated person P raising his/her legs. In other words, the pressure value around 140 where the pressure does not decrease becomes the average normal pressure P3n when the legs are not raised. To calculate normal pressure P3n, for example, the absolute value of the difference between the previous and current values of pressure values P3R, P3L (this value is the current value P3(n) minus the previous value P3(n-1)) is equal to or less than a predetermined value (i.e., when the change in value is small), and then the current values are tallied and averaged.

The threshold value P3th is a threshold value for determining whether the leg is being raised, and in the case of FIG. 3, for example, a value of about 100 to 120 can be used. Therefore, the threshold value P3th can be a value obtained by multiplying the normal pressure P3n by a predetermined value. For example, the threshold value P3th can be a value obtained by multiplying the normal pressure P3n by a predetermined value of about 0.6 to 0.9.

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 P3R, P3L can be determined to have reached their peak when the difference between the previous value and the current value changes from negative to positive under the condition that each pressure value P3R, P3L is smaller than the threshold value P3th (exceeding it from the upper side to the lower side), and the previous value P3(n-1) at this time can be determined to be the peak value Pm.

When the smartphone SP detects peaks in the pressure values P3R, P3L in response to the movement of the seated person P, it calculates the peak value Pm, and calculates the step strength F (FR, FL), which is the magnitude of leg lift, based on the peak value Pm and the normal pressure P3n. The step strength F can be the magnitude of the peak, that is, the value obtained by subtracting the peak value Pm from the normal pressure P3n. In this embodiment, in order to eliminate differences due to 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
Let us assume that.

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

At the end of the 100m sprint game, the smartphone SP obtains the time (time at the finish line of 100m) as an example of an evaluation value, and calculates the average time for a specified period of time in the past. Here, the time can be measured by starting time measurement with a timer from the start of the 100m sprint game, and ending the time measurement when the value obtained by multiplying the number of times step strength F has been calculated by F becomes 100 or more. Since step strength F is calculated based on the pressure value as described above, the smartphone SP calculates the time (evaluation value related to exercise) based on the pressure value (information). The average time for a specified period of time in the past can be, for example, the average time for the past month, or the average time for the past year.

When the 100m game ends, the smartphone SP displays the currently acquired and calculated time and the average time on the display DSP. In addition, if the smartphone SP is able to communicate with the server SV at the end of the 100m game, it transmits the currently acquired and calculated time and the average time to the server SV.

The smartphone SP is capable of acquiring the position of the smartphone SP itself from a position information acquisition unit 2 that utilizes a satellite positioning system. Therefore, when an occupant P seated in the vehicle seat S is operating the smartphone SP, the smartphone SP is able to acquire the position of the vehicle seat S (hereinafter referred to as position information).

The smartphone SP has a function of acquiring the position information acquired from the position information acquisition unit 2 as the position information of the vehicle seat S when the smartphone SP is in a state in which communication with the vehicle seat S is possible. The smartphone SP is also configured to transmit the position information of the vehicle seat S to the server SV.

The server SV stores multiple pieces of advertising information in association with attributes. In this embodiment, as shown in FIG. 4, the multiple pieces of advertising information are associated with the average time for the 100-meter sprint game described above (the athletic ability of the seated person P).

There are multiple pieces of advertising information (e.g., advertisements for sports gyms) corresponding to each attribute, and these pieces of advertising information are associated with the location of each advertiser. Here, the location of the advertiser is the location where the service corresponding to the advertising information is provided, such as the location of a store that provides the service or the location of a store that sells the product corresponding to the advertising information.

The server SV has a function of selecting advertising information related to the average time (the athletic ability of the seated person P) and the location information from among multiple pieces of advertising information based on the average time and the location information transmitted from the smartphone SP. In more detail, if the average time is less than 11 seconds, the server SV selects an advertisement for a sports gym as the advertising information because the athletic ability of the seated person P is high enough to be an athlete.

If the average time is 11 seconds or more and less than 14 seconds, the server SV selects an advertisement for a yoga school where the seated person P can exercise moderately as the seated person P has a relatively high level of physical ability. If the average time is 14 seconds or more and less than 17 seconds, the server SV selects an advertisement for a trekking guide where the seated person P can exercise with less exercise than the yoga school as the seated person P does not have a very high level of physical ability. If the average time is 17 seconds or more, the server SV selects an advertisement for exercise for the elderly as the seated person P is likely to be elderly.

The server SV selects multiple pieces of advertising information (e.g., advertisements for sports gyms) corresponding to the attributes from the table in FIG. 4, and then selects a predetermined number of advertisements from the multiple advertisements based on the position information indicating the position of the vehicle seat S. Specifically, for example, the server SV selects advertising information corresponding to the position of the advertiser within the advertisement selection area that includes the position of the vehicle seat S specified by the position information.

When the server SV selects advertising information based on the average time and the location information, it transmits the selected advertising information to the smartphone SP. By transmitting the advertising information to the smartphone SP, the server SV notifies the seated person P of the advertising information via the smartphone SP.

The smartphone SP has a function to display advertising information transmitted from the server SV on the display DSP to notify the seated person P when a predetermined exercise (one 100m sprint) is completed during the execution of the 100m sprint game. The smartphone SP also has a function to identify the location of the advertiser of the advertising information based on the advertising information transmitted from the server SV, and to display the advertising information on the display DSP to notify the seated person P when the location identified by the location information is within a predetermined area including the advertiser's location.

In more detail, after one 100m sprint game is completed, the smartphone SP transmits the average time and position information to the server SV. Next, when the smartphone SP receives advertising information selected based on the average time and position information from the server SV, it determines whether the position of the vehicle seat S is within a specified area, and if so, displays the advertising information on the display DSP. Note that the specified area is, for example, inside a circle of a specified radius centered on the advertiser's position, and can be smaller than the advertising selection area described above (the area for selecting advertising information from position information in the server SV).

Next, the operations of the smartphone SP and the server SV (more specifically, the respective control units in the smartphone SP and the server SV) will be described in detail.
When the seat occupant P starts the seat application, the smartphone SP starts the process shown in Fig. 5 (START). In this process, the smartphone SP first determines whether or not it is in a state in which it can communicate with the control device 100 of the vehicle seat S (S11).

If it is determined in step S11 that communication is not possible (No), the smartphone SP ends this process. If it is determined in step S11 that communication is possible (Yes), the smartphone SP displays the start screen of the 100m sprint game (see FIG. 7) on the display DSP (S12).

After step S12, the smartphone SP determines whether or not the 100m sprint game has been selected (S13). If it is determined in step S13 that the 100m sprint game has been selected (Yes), the smartphone SP starts the 100m sprint game (S14).

After step S14, specifically during the 100m sprint game, the smartphone SP calculates the time based on the pressure value transmitted from the vehicle seat S (S15). After step S15, specifically after the 100m sprint game ends, the smartphone SP calculates the average value of the current time and the time over a predetermined period of time in the past (S16). After calculating the average value of the time, the smartphone SP displays the current time and the average value of the time on the display DSP (see FIG. 8).

After step S16, the smartphone SP determines whether or not it is in a state where it can communicate with the server SV (S17). If it is determined in step S17 that it is in a state where it can communicate (Yes), the smartphone SP acquires position information indicating the position of the vehicle seat S from the position information acquisition unit 2 (S18).

After step S18, the smartphone SP transmits the average time value and the location information to the server SV (S19). After step S19, the smartphone SP acquires the advertising information, including the advertiser's location information, transmitted from the server SV (S20).

After step S20, the smartphone SP identifies the location of the advertiser based on the acquired advertising information (S21) and sets a predetermined area from the advertiser's location (S22). After step S22, the smartphone SP determines whether the location identified by the location information is located within the predetermined area (S23).

If it is determined in step S23 that the smartphone SP is located within the specified area (Yes), the smartphone SP displays the advertising information on the display DSP (S24). After step S24, if it is determined in step S13 that the 100m sprint game has not been selected (No), or if it is determined in step S17 that communication with the server SV is not possible (No), the smartphone SP determines whether or not the end of the seat app has been selected on the start screen (Figure 7) (S25).

If it is determined in step S25 that end has not been selected (No), the smartphone SP returns to the processing of step S12. If it is determined in step S25 that end has been selected (Yes), the smartphone SP ends this processing.

The server SV constantly executes the process shown in FIG.
6, the server SV determines whether or not the average time value and the location information have been acquired from the smartphone SP (S41). If it is determined in step S41 that the average time value and the location information have not been acquired (No), the server SV ends this process.

If it is determined in step S41 that the advertisements have been acquired (Yes), the server SV selects a predetermined number of advertisements from among the multiple advertisements based on the average time and the location information (S42). After step S42, the server SV transmits the selected number of advertisements to the smartphone SP (S43), and ends this process.

Next, an example of a specific operation of the seat system 1 will be described in detail.
As shown in Fig. 1, when the devices (S, SV, SP) constituting the seat system 1 are in a state in which they can communicate with each other, and the seat occupant P operates the smartphone SP to launch a seat application, the processes in Fig. 5 are executed in order from step S11: Yes to step S12. As a result, the start screen shown in Fig. 7 is displayed on the display DSP.

On the start screen, a button B1 for starting the 100m sprint game and a button B2 for ending the seat app are displayed. When seated person P touches button B1, the answer is determined as Yes in step S13, and the 100m sprint game is executed (S14 to S16).

When the 100m sprint game is over, the smartphone SP calculates the average time (S16) and displays the current time and the average time on the display DSP (see FIG. 8). In this example, as shown in FIG. 8, the average time is set to 10.2 seconds. After that, the smartphone SP executes the process of step S17: Yes → steps S18 to S19 to obtain position information indicating the position of the vehicle seat S and transmits the obtained position information and the average time to the server SV.

As shown in FIG. 6, when the server SV acquires the average time value and location information from the smartphone SP (S41: Yes), in step S42, the server SV selects multiple pieces of advertisement information based on the average time value and the table shown in FIG. 4. In detail, since the acquired average time value is 10.2 seconds, the server SV selects advertisements for multiple sports gyms from the table.

In addition, in step S42, the server SV selects advertisements for a predetermined number of sports gyms that correspond to the location information from among the advertisements for the selected multiple sports gyms based on the location information. The server SV then transmits advertisements for the selected predetermined number of sports gyms to the smartphone SP (S43).

As shown in FIG. 5, when the smartphone SP acquires advertisements for a predetermined number of sports gyms from the server SV (S20), it identifies the location of each advertiser of the advertisements for the predetermined number of sports gyms (S21) and sets a predetermined area for each of the predetermined number of advertisers (S22).

If the location identified by the location information is located within a specified area of a specific advertiser, "XX Sports Gym" (S23: Yes), the smartphone SP displays an advertisement for "XX Sports Gym" on the display DSP, as shown in FIG. 9 (S24). This allows the seated occupant P to know that "XX Sports Gym" is located near his/her current location, and he/she can then tell the driver to move the vehicle toward that location.

As described above, the seat system 1 of the present embodiment can provide the following advantages.
Advertising information is selected based on the average value of the time based on the pressure values acquired by the pressure sensors PS1 to PS3 provided in the seat body S0 and is notified to the seat occupant P, so that advertising information suitable for the physical condition of the seat occupant P seated in the vehicle seat S having the pressure sensors PS1 to PS3 can be notified.

In addition to the average time based on pressure values, which is information corresponding to the physical condition, the location information is referenced to select advertising information, so advertising information suited to the location of seated person P and the physical condition of seated person P can be presented.

The advertising information is notified on the condition that the location specified by the location information is within a specified area, so that the seated person P can quickly move to the location where the goods or services presented in the advertising information can be provided, and can quickly receive the services, etc.

Advertisement information is selected based on the average time, which is an evaluation value related to exercise, so facilities that suit seated person P's athletic ability can be introduced to seated person P.

The selected advertising information is notified to the seated person P on the condition that one 100m sprint game has been completed, so advertising information according to the results of the 100m sprint game can be notified to the seated person.

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

In the above embodiment, the selection of advertising information is performed by the server SV, but the present invention is not limited to this, and advertising information may be selected by the smartphone SP.

In the above embodiment, the advertisement information was selected based on the average time, which is an evaluation value based on information, but the present invention is not limited to this, and, for example, the advertisement information may be selected based on a pressure value as information. Specifically, for example, since the pressure value acquired by the pressure sensors PS1 to PS3 is approximately proportional to the weight of the seated person P, it may be configured to select advertisement information such as diet foods when the pressure value is equal to or greater than a predetermined value, and to select advertisement information such as restaurants when the pressure value is less than the predetermined value.

In the above embodiment, a pressure value is exemplified as the information, but the present invention is not limited to this, and the information may be, for example, blood pressure, heart rate, body temperature, sweat rate, etc. The sensor may be any sensor capable of detecting this information.

For example, if blood pressure is used as the information, advertising information for hospitals, etc. may be selected on the condition that blood pressure is equal to or greater than a predetermined value, and advertising information for sports gyms, etc. may be selected on the condition that blood pressure is less than a predetermined value. In addition, if the information is the amount of sweating, advertising information for beverages suitable for replenishing fluids and salt, such as sports drinks, may be selected on the condition that the amount of sweating is equal to or greater than a first threshold, and advertising information for beverages suitable for normal hydration, such as juices and tea, may be selected on the condition that the amount of sweating is less than the first threshold.

In the above embodiment, the average time was used as an example of an evaluation value related to exercise, but the present invention is not limited to this, and the evaluation value related to exercise may be, for example, the current time or the number of steps.

In the above embodiment, a location information acquisition unit 2 using a satellite positioning system is exemplified, but the present invention is not limited to this. For example, the location information acquisition unit may not only receive radio waves from a positioning satellite, but may also acquire location information by simultaneously transmitting and receiving radio waves from a reference station installed on the ground. In addition, the location information acquisition unit may acquire location information from an ECU or navigation system of the vehicle.

In the above embodiment, a 100m sprint game is exemplified as an exercise program, but the present invention is not limited to this, and the exercise program may be, for example, a Zen meditation game for making a seated person P meditate on a vehicle seat S. The Zen meditation game may be configured as a game that encourages the seated person P to maintain a posture such that the pressure on the left side and the pressure on the right side of the seat cushion S1 are approximately equal, and the pressure on the front side and the pressure on the rear side of the seat cushion S1 are approximately equal. If the result of the Zen meditation game is good, that is, if a good Zen meditation posture is maintained, an advertisement for a facility where a sport suitable for people with good balance, such as a slackline, can be performed, may be selected, and if the result is bad, advertisement information for a balance ball or the like may be selected.

In the above embodiment, the advertising information is notified to the seated occupant P by displaying it on the display DSP, but the present invention is not limited to this. For example, the advertising information may be notified to the seated occupant by voice or the like.

In the above embodiment, a vehicle seat used in an automobile is exemplified as the vehicle seat S, but the present invention is not limited to this and can be applied to other vehicle seats, such as seats used in ships and aircraft. Furthermore, the seat is not limited to the vehicle seat S and may be, for example, a chair.

In the above embodiment, a smartphone SP is used as an example of the terminal, but the present invention is not limited to this, and the terminal may be a mobile terminal other than the smartphone SP, such as a tablet. In addition, the terminal may be a terminal that is attached to the seat and is provided integrally with the seat.

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