Description

The present invention relates to an information processing device, an information processing method, and a program that can provide information about restaurants.

BACKGROUND ART Conventionally, there is a technique of measuring vital data such as a user's body temperature, blood pressure, and pulse, and providing information and contents suitable for the user based on the vital data.

For example, in Patent Document 1 below, based on the driver's health condition data measured by a health sensor installed in the vehicle, a restaurant that provides a meal of a genre according to the driver's health condition is set as a recommended destination. A system for extracting and presenting it to the driver is described.

JP, 2002-310686, A

However, in the technique described in Patent Document 1, a restaurant is presented as a destination only when a request for starting destination setting is received from the user, and therefore the user has already visited at the time of setting the destination. The image of the desired restaurant may be solid, or the user may not be hungry. In that case, since the user does not show interest in the presented restaurant, the presented information and the processing therefor are wasted.

In view of the circumstances as described above, an object of the present invention is to provide an information processing device, an information processing method, and a program capable of providing restaurant information at optimal timing according to the degree of hunger of a user. ..

To achieve the above object, an information processing device according to an aspect of the present invention includes a storage unit, a communication unit, and a control unit. The storage unit stores restaurant information about a plurality of restaurants and pattern data generated based on the user's vital data and showing an average transition of the hunger degree of the user in one day. The communication means receives the vital data of the user via a sensor device existing at least in the vicinity of the user. The control means compares the transition of the received vital data with the stored pattern data to estimate the time when the hunger degree of the user becomes maximum in a certain cycle. Further, the control means controls the communication means to transmit the stored restaurant information to the sensor device or a user terminal connected to the sensor device a predetermined time before the estimated time.

With this, the information processing apparatus can provide the restaurant information at the optimum timing according to the hunger degree of the user by determining the state before the predetermined time when the hunger degree of the user becomes maximum. That is, by transmitting the restaurant information before the predetermined time when the hunger becomes the maximum, when the user browses the restaurant information and moves to the restaurant indicated by it, the hunger degree after the predetermined time has elapsed The possibility of becoming the maximum is increased, and the user can have a meal at an appropriate hunger timing. Here, the sensor device may be, for example, a wearable terminal that can be worn by a user, and the user terminal may be, for example, a smartphone. Further, the predetermined time before is, for example, 5 minutes, 10 minutes, 15 minutes, 30 minutes, etc., but is not limited to this. The predetermined time may be a travel time calculated based on the distance from the position of the user terminal to the restaurant indicated by the advertisement information.

The storage means classifies and stores the restaurant information into first restaurant information having at least a first weight and second restaurant information having a second weight smaller than the first weight. You may. In this case, the control means, from the transition of the received vital data, that the hunger degree has risen after falling by a predetermined threshold value or more during the period from the time when the hunger degree becomes the minimum to the time when the hunger degree becomes the maximum. When it is determined, the communication means may be controlled to preferentially transmit the second restaurant information.

Accordingly, when the information processing apparatus estimates that the user had a snack between before the maximum hunger degree (before the normal meal time) from the transition of the user's vital data, the information processing apparatus has a small weight. By preferentially distributing the restaurant information of the store, it is possible to increase the possibility that the user can find the restaurant suitable for the hunger degree of the user from the restaurant information. Here, as the weight, for example, a normal meal and a light meal may be used, or an energy amount (calorie) of food and drink (menu) provided by each restaurant may be used. Therefore, when it is estimated that the user ate between snacks, the restaurant information of the restaurant that provides a lighter (low energy amount) meal is provided.

From the transition of the received vital data, the control means determines that the hunger degree has risen after decreasing by a predetermined threshold value or more in the period from the time when the hunger degree becomes the minimum to the time when the hunger degree becomes the maximum. In that case, the vital data from the start of the descent to the return to the hunger degree at the start of the descent may be excluded to estimate the time at which the hunger degree of the user becomes the maximum in a certain cycle.

Thereby, even if it is estimated from the transition of the user's vital data that the user ate a snack before the hunger level reached its maximum, the information processing apparatus excludes the vital data for that snack to provide a snack. If not, the restaurant information can be transmitted a predetermined time before the time when the hunger degree of the user becomes maximum in a certain cycle. This is because even if the user has a snack, it is considered that the user often habitually eats at the same time as when the user did not have a snack.

The storage means may store the restaurant information in association with the amount of energy of food and drink provided at the restaurant. In this case, the control means, from the transition of the received vital data, that the hunger degree has risen after falling by a predetermined threshold value or more during the period from the time when the hunger degree becomes the minimum to the time when it becomes maximum. If judged, the restaurant information associated with the energy amount obtained by subtracting the energy amount corresponding to the lowered hunger degree from the average value of the energy amount of food and drink provided at all restaurants is given priority. The communication means may be controlled so that the data is transmitted in an appropriate manner.

As a result, when the information processing apparatus estimates that the user has snacked before the maximum hunger degree is obtained from the transition of the user's vital data, the food and drink obtained by subtracting the energy amount (calorie) of the snack between meals. By preferentially distributing the restaurant information of the restaurant that provides the information, it is possible to increase the possibility that the user can find a restaurant suitable for the hunger degree of the user from the restaurant information.

When it is determined from the transition of the vital data that the hunger degree of the user is stagnation for a predetermined period or more in the vicinity of the maximum value in a certain cycle, the control means sets a predetermined period within the stagnation period. The communication means may be controlled to transmit the restaurant information at a frequency.

Thus, when it is estimated that the user is hungry and has not eaten yet, the information processing device can transmit restaurant information at a predetermined frequency so that the user can find a desired restaurant. You can improve your sex. For example, when the user is hungry, even if he/she does not have time to view the restaurant information due to work or the like, he/she can quickly find the desired restaurant by collectively viewing the restaurant information received when his/her hands become available. Can be found in Here, the predetermined frequency is, for example, 5 minutes, 10 minutes, 15 minutes, etc., but is not limited to this.

The sensor device may be provided in an in-vehicle component of a vehicle in which the user is riding. In this case, the transmitted restaurant information may be output from the output unit provided in the vehicle.

Thereby, the information processing apparatus can provide the restaurant information of the restaurant to the user at an optimal timing according to the hunger degree even when the user is in the vehicle. Here, the vehicle interior component is, for example, a steering wheel or a seat if the vehicle is a passenger vehicle, but is not limited to this.

An information processing apparatus according to still another aspect of the present invention includes a storage unit, a communication unit, and a control unit. The storage means stores the restaurant information relating to the plurality of restaurants in association with the amount of energy of the food and drink provided at each of the restaurants, and is generated based on the user's vital data for one day of the user. The pattern data showing the average transition of the hunger degree among the above and the correspondence information of the energy amount and the hunger degree are stored. The communication means receives the vital data of the user via a sensor device existing at least in the vicinity of the user. The control means estimates the hunger degree of the user by comparing the transition of the received vital data and the stored pattern data, and in the stored restaurant information, the estimated hunger degree. The communication means is controlled so as to transmit the restaurant information of at least one restaurant where food and drink having an energy amount corresponding to is transmitted to the sensor device or a user terminal connected to the sensor device.

Accordingly, the information processing apparatus can provide the user with restaurant information of a restaurant that provides food and drink with an energy amount corresponding to the current hunger degree of the user.

A vehicle according to another aspect of the present invention includes a storage unit, a seat, a sensor device, an output unit, and a control unit. The storage means is capable of storing at least temporarily restaurant information about a plurality of restaurants, and is generated based on the vital data of the user, and shows the average transition of the hunger degree of the user during the day. It is possible to store pattern data. The user can sit on the seat. The sensor device is provided at least in the vicinity of the user who is sitting on the seat, and is able to acquire the vital data of the user. The control means compares the transition of the acquired vital data with the stored pattern data, estimates the time when the hunger degree of the user is maximum in a certain cycle, and determines the predetermined time of the estimated time. The output means is controlled to output the stored restaurant information before the time.

It is the figure which showed the schematic structure of the vehicle which concerns on other embodiment of this invention.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[System configuration]
FIG. 1 is a diagram showing the configuration of a restaurant information providing system according to this embodiment.

As shown in the figure, this system includes a restaurant information providing server 100 on the Internet 50, a plurality of user terminals 200 and a plurality of wearable terminals 300.

The restaurant information providing server 100 is a web server that operates a portal site that publishes information about restaurants. The restaurant information providing server 100 is connected to a plurality of user terminals 200 via the Internet 50.

The restaurant information providing server 100 provides a restaurant information search system for the user of the user terminal 200 on the portal site. Specifically, the restaurant information providing server 100 searches for restaurant information that matches the search condition based on the search request from the user terminal 200, generates a Web page in which the search result is posted, and sends it to the user terminal 200. Send.

In addition, in the present embodiment, the restaurant information providing server 100 determines the hunger degree of the user based on the vital data of the user of the user terminal 200, and transmits the advertisement information of the restaurant to the user terminal 200 according to the hunger degree. It is possible.

The user terminals 200 (200A, 200B, 200C...) Are terminals used by users, and are portable devices such as smartphones and tablet PCs (Personal Computers). The user terminal 200 accesses the restaurant information providing server 100, receives the Web page, and displays it on the screen using a browser or the like.

The wearable terminal 300 is a terminal that is worn and used by a user, and is, for example, a smart watch having a wristband that can be worn on the arm of the user. For example, the wearable terminal 300 uses a wireless communication technology such as Bluetooth (registered trademark) or Wi-Fi. , And can communicate with the user terminal 200.

The wearable terminal 300 has a built-in sensor capable of non-invasively measuring vital data such as the blood glucose level of the user, and the measured vital data is periodically sent to the restaurant information providing server 100 via the user terminal 200, for example. It is possible to send to.

Here, the blood glucose level is used as the vital data for determining the hunger degree because, generally, the lower the blood glucose level, the higher the hunger degree.

As the sensor, the LED provided on the wristband portion of the user terminal 200 (the portion that contacts the user's wrist) irradiates the blood vessels on the user's wrist with mid-infrared light, and the mid-infrared light emits glucose ( By utilizing the property of being strongly absorbed by blood glucose) and hardly absorbed by biological components other than water and alcohol, a configuration for measuring the glucose concentration from the reflected light of the above mid-infrared light may be used.

Of course, the configuration of the sensor is merely an example, and the blood glucose level and the blood pressure may be measured by another method using the user terminal 200.

The advertisement information is received, for example, as a Web page by the user terminal 200 and viewed by the user via the browser of the user terminal 200. The advertisement information is transferred from the user terminal 200 to the wearable terminal 300 and displayed on the wearable terminal 300. It may be displayed above.

In addition, when the wearable terminal 300 supports a mobile phone communication standard such as 3G or LTE (Long Term Evolution), the wearable terminal 300 directly communicates with the restaurant information providing server 100 and transmits vital data. Also, the advertisement information may be received. In this case, the user terminal 200 is unnecessary for the above system.

[Hardware configuration of restaurant information server]
FIG. 2 is a diagram showing a hardware configuration of the restaurant information providing server 100. As shown in FIG. 1, the restaurant information providing server 100 includes a CPU (Central Processing Unit) 11, a ROM (Read Only Memory) 12, a RAM (Random Access Memory) 13, an input/output interface 15, and these components are connected to each other. The bus 14 is provided.

The CPU 11 appropriately accesses the RAM 13 and the like as necessary and performs overall control of all blocks of the restaurant information providing server 100 while performing various arithmetic processes. The ROM 12 is a non-volatile memory in which an OS to be executed by the CPU 11 and firmware such as programs and various parameters are fixedly stored. The RAM 13 is used as a work area of the CPU 11, etc., and temporarily holds the OS, various applications being executed, and various data being processed.

The display unit 16 is a display device using, for example, an LCD (Liquid Crystal Display), an OELD (Organic ElectroLuminescence Display), a CRT (Cathode Ray Tube), or the like.

The operation reception unit 17 is, for example, a pointing device such as a mouse, a keyboard, a touch panel, and other input devices. When the operation reception unit 17 is a touch panel, the touch panel can be integrated with the display unit 16.

The storage unit 18 is a nonvolatile memory such as an HDD (Hard Disk Drive), a flash memory (SSD; Solid State Drive), or other solid-state memory. The storage unit 18 stores the OS, various applications, and various data.

As will be described later, particularly in the present embodiment, the storage unit 18 has a restaurant information database, a user information database, and a vital pattern database.

The communication unit 19 is various modules for wireless communication such as a NIC (Network Interface Card) for Ethernet (registered trademark) and a wireless LAN, and is responsible for communication processing with the user terminal 200.

Although not shown, the basic hardware configuration of the user terminal 200 is substantially the same as the hardware configuration of the restaurant information providing server 100.

[Database configuration of restaurant information server]
FIG. 3 is a diagram showing a configuration of a database included in the restaurant information providing server 100.

As shown in the figure, the restaurant information providing server 100 has a restaurant information database 31, a user information database 32, and a menu correspondence information database 33 in the storage unit 18.

The restaurant information database 31 has, for each restaurant, a store name and location information of the restaurant, an ID (store ID) for identifying the restaurant, category information of the business type/service of the restaurant, and the restaurant. The contents of introducing, that is, information indicating the characteristics of the store such as a PR statement of the store, event information performed by the restaurant, area information in which the restaurant is located, the address of the restaurant, the telephone number, the restaurant ( Image data, menu information about menus provided by restaurants, business hours, website URL, and other information are stored. Advertisement information transmitted to the user terminal 200 or the wearable terminal 300 is generated by at least a part of these pieces of information.

The restaurant information database 31 may further store each average value of the energy amount (calorie) of all menus or typical menus provided at each restaurant. Further, in the restaurant information database 31, each restaurant is classified into at least a first restaurant having a first weight and a second restaurant having a second weight smaller than the first weight. May be. Typically, the first restaurant is a regular restaurant and the second restaurant is a light restaurant. The classification may be performed according to the average value of the calories in the menu provided by each restaurant. In this case, the weight is the calorie of the menu provided at each restaurant. In addition, for example, the classification may be performed based on the normal food/snacks classification information that is also provided when each restaurant provides the restaurant information providing server 100 with the restaurant information. In this case, the difference in the classification information input as a part of the restaurant information by each restaurant becomes the weight. In addition to this, the first restaurant and the second restaurant may be classified according to categories such as Japanese food, Western food, and Chinese food.

The menu information is information corresponding to the menu posted on the site of each restaurant on the portal site, and stores the menu name of a plurality of menus that each restaurant can provide, for each restaurant. .. The menu information may be stored for each menu category such as appetizer/main, lunch/dinner/course.

The area information is, for example, in units of prefectures, but the information may be stored in units of a narrower range such as municipalities. The category information may include, for example, main categories such as Japanese food, Chinese food, Italian food, French food, and yakiniku, as well as more detailed subcategories such as yakitori and tempura in Japanese food, and pasta and pizza in Italian food.

The user information database 32 is information about a user who owns the user terminal 200 and/or the wearable terminal 300 and who is a user (member) of the restaurant information service via the portal site provided by the restaurant information providing server 100. Memorize Specifically, the user information database 32 stores information such as a user ID, a password, a name, a mail address, a telephone number, an address, an age (layer), a sex, and a birthday for each user. The user information database 32 may also store information regarding the address or area of the user's workplace.

The vital pattern database 33 stores data indicating the average transition (vital pattern) of the hunger degree of each user stored in the user information database 32 per day. The vital pattern may be generated from vital data (blood glucose level data) of the user for a predetermined period (for example, one week, one month, etc.) received by the restaurant information providing server 100 from the user terminal 200 or the wearable terminal 300. It may be generated from the vital data measured in the wearable terminal 300 for the predetermined period and transmitted to the restaurant information providing server 100.

Further, the pattern data may be graph data showing the transition of the vital data (blood glucose level) as it is, or the value (blood glucose level) in the vital data is converted into hunger (the lower the blood glucose level, the lower the blood glucose level). It may be graph data shown such that the hunger degree is high.

Each of these databases is used with reference to each other as needed in the restaurant information providing process by the restaurant information providing server 100 described later.

[Operation of restaurant information providing server]
Next, the operation of the restaurant information providing server 100 configured as above will be described. The operation is executed by the cooperation of the CPU 11 of the restaurant information providing server 100 and the hardware such as the communication unit 19 and the software stored in the storage unit 18. In the following description, the CPU 11 will be the main subject of operation for convenience.

FIG. 4 is a flowchart showing a flow of restaurant advertisement information providing processing by the restaurant information providing server 100. In the example of the figure, the case where the restaurant information providing server 100 provides the user of the user terminal 200 with the advertisement information of the restaurant for lunch will be described.

As shown in the figure, the CPU 11 of the restaurant information providing server 100 first determines whether or not a predetermined time for starting the advertisement information providing process of the restaurant has come (step 41). The predetermined time is, for example, several hours before the time when the hunger degree is maximum in a certain cycle (for example, between breakfast and lunch) in the vital pattern of the user of the user terminal 200, but is not limited thereto.

When determining that the predetermined time has arrived (Yes), the CPU 11 determines whether or not vital data up to the present has been received from the user terminal 200 (or wearable terminal 300) (step 42). The vital pattern is received together with the user ID that identifies the user of the user terminal 200, for example.

FIG. 5 is a diagram showing an example of a vital pattern of a certain user stored in the vital pattern database 33. The vital pattern shown in the same figure is an example in which the blood glucose level is measured as vital data and the transition thereof is stored as it is as a vital pattern.

As shown in the figure, a user having this vital pattern has a blood glucose level starting to rise at about 6 o'clock, reaching a maximum value in the cycle at about 9 o'clock, and reaching a minimum value in the cycle at about 12 o'clock, Furthermore, the maximum value in the next cycle is reached around 15:00. From this pattern, it can be seen that the user usually eats breakfast around 6 o'clock and eats lunch around 12 o'clock, and reaches the peak of hunger at about 12 o'clock in the cycle from morning to noon.

Therefore, the restaurant information providing server 100 can estimate the time when the user reaches the peak of hunger by comparing the value of the received vital data in a specific cycle (time zone) with this vital pattern. It will be possible.

When it is determined that the vital data has been received (Yes), the CPU 11 determines whether or not the hunger degree above or above a threshold value has risen or fallen in a certain cycle of the received vital data (whether or not it has risen after falling below the threshold value). (Step 43).

If it is determined that the hunger degree is equal to or higher than the threshold value (Yes), the CPU 11 determines that the user has had a snack between the breakfasts (between breakfast and lunch), turns on the snack flag, and causes the hunger. The vital data from the start of the descent of the degree equal to or higher than the threshold to the return to the hunger degree at the start of the descent are excluded (step 44).

Subsequently, the CPU 11 extracts a vital pattern corresponding to the user ID from the vital pattern database 33, and extracts the vital pattern and the received vital data (data that excludes that portion if there is a snack). By comparing the above, the time when the hunger degree of the user becomes maximum (the blood glucose level of the user becomes the minimum) in the target cycle (the cycle from 6:00 to 12:00 in the example of FIG. 5) is estimated (step). 45).

Subsequently, the CPU 11 determines whether or not it is a predetermined time before the estimated time (step 46 ), and when it is determined that the predetermined time is before (Yes), from the restaurant information database 31 to the user terminal. The advertisement information of the restaurant suitable for the 200 users is extracted (step 47) and transmitted to the user terminal 200 (step 48).

Here, the predetermined time is, for example, a travel time of the user to the restaurant, and is, for example, 10 minutes, 15 minutes, 30 minutes, or the like, but is not limited thereto. Further, the advertisement information of the restaurant transmitted to the user terminal 200 is acquired from, for example, the work address or home address (area) of the user of the user terminal 200 registered in the user information database 32 in advance, or the user terminal 200. Advertisement information of restaurants searched based on the current position information may be extracted. The travel time is based on the distance from the home (or work) address (area) or the current position of the user terminal 200 to the location of the restaurant indicated by the extracted advertisement information, and for example, the distance is walked. It may be calculated as moving.

FIG. 6 is a diagram for explaining the exclusion process when it is estimated that the user has snacked. As shown in the graph in the upper part of the figure, when it is determined from the vital data that the hunger level is above or below the threshold Th, the CPU 11 lowers the threshold or more (increases the blood glucose level or more by the threshold or more). ) Is excluded from the vital data of period T from the start of) until returning to the hunger level at the start of descent (until returning to the blood glucose level at the start of rising), and the previous time by the amount of the vital data in the subsequent period. Move away.

As a result, as shown in the graph in the lower part of the figure, the CPU 11 estimates the time when the user's hunger becomes the maximum in a certain cycle, assuming that he does not eat between meals, and the advertisement information is displayed a predetermined time before that time. Can be sent. This is because even if the user has a snack, it is considered that the user often eats at the same time as if he/she did not have a snack.

Here, the restaurant information providing server 100, in the restaurant information database 31, sets the advertisement information to at least the advertisement information of the first restaurant (regular meal restaurant) and the second restaurant (light meal restaurant). ) Advertising information may be classified and stored. In this case, when the snack flag is turned on (when the hunger degree is above or above the threshold value), the CPU 11 determines whether the second restaurant (in the advertisement information extracting process in step 47). The advertisement information of the snack restaurant is preferentially extracted and transmitted to the user terminal 200.

This increases the possibility that even a user having a snack can find a restaurant suitable for the hunger level of the user by browsing the advertisement information of the snack restaurant.

FIG. 7 is a diagram showing an example of advertisement information of restaurants transmitted to the user terminal 200. As shown in the figure, the advertisement information is transmitted and displayed, for example, as a list in the restaurant information column 71 of a plurality of restaurants satisfying the search condition. In each restaurant information column 71, a detailed button 72 is provided in addition to, for example, a restaurant name, access information, budget, commitment information, a photograph and the like. The detail button 72 is set with a hyperlink of a page on which more detailed information (for example, menu information, map information, etc.) about the restaurant is set, and when the user presses the detail button 72, the restaurant information is displayed. The list page in column 71 transitions to the detail page.

Returning to FIG. 4, the CPU 11 receives the vital data from the user terminal 200 even after the advertisement information is distributed, and the hunger degree of the user in the above cycle is stagnation for a predetermined period or more near its maximum value (minimum blood glucose level). When it is determined that it is still (Yes in step 49), the advertisement information is transmitted to the user terminal 200 at a predetermined frequency within the stagnation period. The advertisement information transmitted in this case may be the same advertisement information as the advertisement information of the restaurant already transmitted, or may be the advertisement information of another restaurant satisfying the above conditions.

Here, the CPU 11 may increase the frequency of transmission of the advertisement information as the time when the hunger degree of the user is estimated to be the maximum is approached.

As a result, when it is estimated that the user is hungry and has not eaten, the CPU 11 retransmits the advertisement information at a predetermined frequency so that the user may find the desired restaurant. Can be increased.

For example, if the user is hungry and does not have time to view the advertising information due to work, etc., then, by collectively viewing the advertising information received when the user is available, the desired restaurant can be immediately displayed. Can be found. Here, the predetermined frequency is, for example, 5 minutes, 10 minutes, 15 minutes, etc., but is not limited to this.

Then, when the CPU 11 determines in step 49 that the hunger degree of the user has decreased (blood sugar level has increased), the user is considered to have eaten (is eating), and therefore the advertisement information is transmitted. The process ends.

[Summary]
As described above, according to the present embodiment, the restaurant information providing server 100 determines the optimum timing according to the hunger degree of the user by determining the state before the predetermined time when the hunger degree of the user becomes maximum. Advertising information for restaurants can be provided at. That is, by transmitting the advertisement information before the predetermined time when the hunger degree becomes the maximum, when the user browses the advertisement information and moves to the restaurant indicated by the advertisement information, the predetermined time period elapses and the hunger degree becomes the maximum. Therefore, the user can have a meal at an appropriate hunger timing.

[Modification]
The present invention is not limited to the above-described embodiments, but can be variously modified without departing from the scope of the present disclosure.

In the above-described embodiment, when it is determined that the user has snack between meals in the predetermined cycle, the advertisement information of the snack restaurant is provided to the user. However, the restaurant information providing server 100 may extract the advertisement information of the restaurant based on the energy amount (calorie) of the snack.

Specifically, when the advertisement information is stored in the restaurant information database 31 in association with the calories of the food and drinks provided at each restaurant, and the CPU 11 turns on the snack bar flag ( If there is an increase or decrease in hunger above the threshold value), it is associated with a calorie obtained by subtracting the calorie according to the lowered hunger from the average value of the calories of food and drink provided at all restaurants. Advertising information may be preferentially transmitted.

Accordingly, when it is estimated that the user has snack between meals, the restaurant information providing server 100 preferentially distributes the advertisement information of the restaurant that provides food and drink in which calories for the snack are subtracted, thereby It is possible to increase the possibility that the user can find a restaurant suitable for the hunger degree of the user from the advertisement information.

In the above-described embodiment, the restaurant information providing server 100 determines whether or not the user has eaten a meal (or snack) from the transition of vital data, but the restaurant information providing server 100 further From the transition of vital data, the food (or the component mainly contained in it) eaten by the user may be estimated. That is, it is generally known that there is a difference in the rise pattern of the blood glucose level depending on carbohydrates (rice/bread/noodles), proteins, lipids, etc. Therefore, the restaurant information providing server 100 determines that the patterns are different. It is possible to memorize the data related to and estimate the food (main component) that the user ate from the transition of vital data. Then, the restaurant information providing server 100 may select the advertisement information of the restaurant to be provided according to the estimated difference in the food (main component). For example, when it is estimated that the user has eaten noodles in one meal, advertisement information of a restaurant that mainly provides food other than noodles may be provided for the next meal.

In the above-described embodiment, the restaurant information providing server 100 regards the user as having a snack between when the user has a hunger level above or below a threshold value, and accordingly, for a normal meal thereafter. It was extracting advertisement information for restaurants. However, at the restaurant information providing server 100, a change in the predetermined hunger degree larger than the threshold for determining the snack between the vital data is obtained from the vital data at a time greatly separated from the time when the user normally eats in the vital pattern of the user. If it is detected, it may be regarded as a meal instead of a snack, and the advertisement information provision process may be stopped.

In the above-described embodiment, the restaurant information providing server 100 estimates the time when the hunger degree of the user is the maximum based on the vital data of the user, and transmits the advertisement information of the restaurant before the predetermined time. .. However, the restaurant information providing server 100 may transmit the advertisement information according to the hunger degree of the user at that time even when the hunger degree of the user is not the maximum.

That is, in this case, the restaurant information providing server 100 further stores the restaurant information in the restaurant information database 31 in association with the calories of the food and drink provided at each of the restaurants and stores the calories. And the correspondence information between the hunger degree and Then, the restaurant information providing server 100 estimates the hunger degree of the user by comparing the transition of the received vital data and the stored pattern data, and estimates the hunger level of the stored restaurant information. The restaurant information of at least one restaurant where food and drink having calories according to the determined hunger degree is provided is transmitted to the user terminal 200 or the wearable terminal 300. Thus, the restaurant information providing server 100 can provide the user with the restaurant information of the restaurant that provides food and drink with calories corresponding to the current hunger level of the user.

In the above-described embodiment, the blood glucose level is used as vital data, but other vital data can be applied to the present invention as well.

For example, the blood pressure tends to drop like a blood glucose level when fasting, and thus the same processing as that of the above-described embodiment can be applied to blood pressure. In order to measure the blood pressure, the blood vessel of the user's wrist is irradiated with near-infrared light from the LED provided in the wristband portion as in the above embodiment, and the pulsation of the blood vessel is measured from the reflected light. A configuration may be used in which the stiffness of the blood vessel wall and the propagation velocity of pulsation are calculated to derive the blood pressure from those values. Instead of this, a blood pressure may be measured by a general oscillometric method by providing a cuff (compression band) on at least a part of the wrist band and thereby compressing the wrist to stop blood flow.

Further, since the body temperature tends to decrease at the time of fasting and the heart rate tends to increase at the time of fasting, utilizing these tendencies, based on the data of the body temperature or the heart rate measured by the sensor, the above embodiment and Similar advertisement information providing processing may be executed.

In the above-described embodiment, the user wears the wearable terminal 300 having a built-in sensor capable of measuring the vital data of the user, and the measured vital data is provided to the restaurant information via the user terminal 200 or directly. An example is shown of being sent to the server 100. However, the sensor may be provided in an in-vehicle component of the vehicle in which the user is riding.

FIG. 8 is a diagram showing a schematic configuration of a vehicle (passenger vehicle) in this case. As shown in the figure, the vehicle 80 is provided with a steering wheel 81 as a part of a steering device and a driver's seat 82 on which a user sits, as in-vehicle components. A sensor 83 for measuring vital data (blood glucose level, etc.) of the user is provided at a portion of the handle 81 that touches the user's hand. The sensor 83 is connected to the control unit 84, and the control unit 84 is connected to the output unit 85.

The control unit 84 has hardware necessary for the computer, such as a CPU, a RAM, and a ROM, and is incorporated in the vehicle 80 as a control circuit or a control unit. The specific configuration of the control unit 84 is not limited, and for example, a device such as a PLD (Programmable Logic Device) such as FPGA (Field Programmable Gate Array) or other ASIC (Application Specific Integrated Circuit) may be used. The output unit 85 is provided as a display of a car navigation device, for example.

The ROM stores a program necessary for the advertisement information providing process, and the CPU loads the program into the RAM and executes the program to execute the advertisement information providing process.

Specifically, the vital data acquired from the sensor 83 is transmitted to the restaurant information providing server 100 via the user terminal 200 carried by the user or directly, and extracted by the same processing as the above-described embodiment. The restaurant advertisement information thus obtained is received by the control unit 84 and displayed on the output unit 85.

Further, the advertisement information of the restaurant may be stored in advance in the storage device such as the ROM of the control unit 84. In this case, the advertisement information may be provided without going through the restaurant information providing server 100. That is, the control unit 84, based on the vital data acquired from the sensor 83, by the same processing as the restaurant information providing server 100 in the above embodiment, estimates the time when the hunger degree of the user is the maximum, and the predetermined time thereof. Previously, the advertisement information of the restaurant searched based on the current position of the vehicle 80 is extracted from the stored advertisement information and output from the output unit 85.

As a result, even when the user is in the vehicle, the advertisement information of the restaurant is provided to the user at an optimal timing according to the hunger degree.

In the above-described embodiment and modification, the advertisement information of the restaurant is shown as the restaurant information provided to the user terminal 200 or the wearable terminal 300, but the provided restaurant information is not limited to the advertisement information. .. For example, ranking information of restaurants in the area associated with the position of the user terminal 200, word-of-mouth/review information for the restaurants, and recipe information of menus provided at the restaurants may be provided.
