[0004] However, the above-described conventional technology has room for improvement. For example, the above-described conventional technology only takes into account the context of the user's environment at the time of notification, and depending on the content the user was exposed to before the time of notification, appropriate information may not be provided even if the context is the same at the time of notification. Therefore, it is desirable to provide appropriate information to the terminal device used by the user.

[0009] Hereinafter, a detailed description will be given of an information processing device, an information processing method, and an information processing program (hereinafter referred to as an "embodiment") according to the present application, with reference to the drawings. Note that the information processing device, the information processing method, and the information processing program according to the present application are not limited to the embodiment. Furthermore, the same components in the following embodiments are denoted by the same reference numerals, and redundant description will be omitted.

[0010] (Embodiment) [1. Information Processing] [1-1. Overall overview] First, an example of information processing according to the embodiment will be described with reference to Fig. 1. Fig. 1 is a diagram showing an example of information processing according to the embodiment.

[0011] In FIG. 1, the information processing device 100 provides the terminal device 10 used by the user with suggested information determined based on changes in the user's context. The changes in the user's context here correspond to changes in the user's state (journey). Specifically, the information processing device 100 determines suggested information to be proposed to the user based on changes in the user's context estimated based on sensor information detected by a sensor, and provides the determined suggested information to the terminal device 10 used by the user. The sensor information includes various information detected by the sensor regarding the state of the terminal device 10 or the environment surrounding the terminal device 10. For example, the sensor information may be information regarding various objects such as temperature, air pressure, sound, vibration, acceleration, illuminance (brightness), and position. Note that the above is merely an example, and the sensor information may be information regarding any object detected by a sensor. For example, the sound is not limited to audible frequency sound but may be ultrasonic, and the audible frequency sound is not limited to voice such as a user's (person's) speech but may also be environmental sound, noise, etc. Furthermore, for example, the sensor information may be biological information such as blood glucose level information indicating the user's blood glucose level, heart rate information indicating the heart rate, and the like.

[0012] In the example shown below, a store is used as an example of a facility, and a case will be described in which the information processing device 100 provides information on objects of provision such as products provided at the store as suggested information to the terminal device 10 used by the user. Note that the store is merely an example, and the facility is not limited to a store. The facility (target facility) for which the information processing device 100 provides suggested information to the terminal device 10 may be any object as long as it is an object for which suggested information is provided.

[0013] FIG. 1 also illustrates an example in which the information processing device 100 estimates a user's movement state and entrance and exit into a store as examples of context. Note that the above is merely an example, and the context may be, for example, information about the user. For example, the context may be various situations of the user estimated based on the situation of the user or the terminal device 10 or the environment (background) of the user or the terminal device 10. The context may also be the physical environment in which the user is placed, the social environment in which the user is placed, the user's exercise state, estimated emotions of the user, etc. The context may also be the psychological state of the user estimated based on the situation of the user or the terminal device 10 or the environment (background) of the user or the terminal device 10.

[0014] [1-1-1. Information Processing System Configuration] The following will first describe the configuration of the information processing system 1 using FIG. 2, and then describe the details of the processing in FIG. 1. FIG. 2 is a diagram illustrating an example of the configuration of the information processing system according to an embodiment. As illustrated in FIG. 2, the information processing system 1 includes a terminal device 10, a store device 20, a data providing device 50, and an information processing device 100. The terminal device 10, the store device 20, the data providing device 50, and the information processing device 100 are connected to each other via a predetermined network N so as to be able to communicate with each other via wired or wireless communication. Note that the information processing system 1 illustrated in FIG. 2 may include a plurality of terminal devices 10, a plurality of store devices 20, a plurality of data providing devices 50, and a plurality of information processing devices 100.

[0015] The terminal device 10 is a computer used by a user. The terminal device 10 is realized by, for example, a smartphone, a tablet terminal, a notebook PC (Personal Computer), a desktop PC, a mobile phone, a PDA (Personal Digital Assistant), or the like. FIG. 1 shows a case where the terminal device 10 is a smartphone. Note that, hereinafter, the terminal device 10 may be referred to as a user. That is, hereinafter, the user may be read as the terminal device 10.

[0016] The terminal device 10 has various sensors that detect various types of sensor information. The terminal device 10 detects sensor information using the various sensors. The terminal device 10 transmits the sensor information detected by the sensors to the information processing device 100. The terminal device 10 has a temperature sensor and detects temperature information (sensor information) of the environment surrounding the user. The terminal device 10 has a barometric pressure sensor and detects barometric pressure information (sensor information) of the environment surrounding the user. The terminal device 10 has a sound sensor such as a microphone and detects audio information (sensor information) of the environment surrounding the user. The terminal device 10 has a vibration sensor and detects vibration information (sensor information) related to the terminal device 10. The terminal device 10 has an acceleration sensor and detects acceleration information (sensor information) related to the terminal device 10. The terminal device 10 has an illuminance sensor and detects illuminance information (sensor information) of the environment surrounding the user. The terminal device 10 may also have an image sensor such as an image sensor and detect image information (sensor information) of the environment surrounding the user.

[0017] The terminal device 10 also has a location sensor and detects user location information (sensor information). For example, the terminal device 10 has a GPS (Global Positioning System) sensor. The terminal device 10 may also detect and acquire user location information (sensor information) using a predetermined wireless communication function such as Wi-Fi (registered trademark) (Wireless-Fidelity) or Bluetooth (registered trademark), a function such as a beacon, or location information of a base station with which the terminal device 10 is communicating. Note that, hereinafter, location information may be simply referred to as "location." For example, the terminal device 10 may improve the accuracy of estimating the user location by combining information from the GPS, the above-mentioned wireless communication function, and a beacon. The terminal device 10 also transmits the user location to the information processing device 100.

[0018] Furthermore, the terminal device 10 collects various types of information other than the sensor information and transmits the collected information to the information processing device 100. The terminal device 10 transmits behavioral information indicating the behavior of the user using the terminal device 10 to the information processing device 100. The terminal device 10 transmits behavioral information related to a payment made using the terminal device 10 to the information processing device 100. The terminal device 10 transmits behavioral information related to a payment (settlement) made at a store using the terminal device 10 to the information processing device 100. The terminal device 10 transmits behavioral information indicating an operation by the user to the information processing device 100. The terminal device 10 transmits behavioral information indicating the behavior of the user on the Internet to the information processing device 100. For example, the terminal device 10 transmits behavioral information including posted information (input information) such as posts by the user to a social networking service (SNS) to the information processing device 100. For example, the terminal device 10 transmits behavioral information including posted information posted by the user to Twitter (registered trademark), Facebook (registered trademark), Instagram (registered trademark), etc. to the information processing device 100.

[0019] The terminal device 10 receives various information from the information processing device 100. The terminal device 10 receives suggested information from the information processing device 100. The terminal device 10 receives coupons for products offered by stores from the information processing device 100.

[0020] In the following, a user identified by a user ID "U1" may be referred to as "user U1." In this way, in the following, when "user U* (* is an arbitrary numerical value)" is written, it indicates that the user is a user identified by the user ID "U*." In addition, in the example shown in FIG. 1, the terminal device 10 will be described as terminal device 10-1 depending on the user who uses the terminal device 10. For example, the terminal device 10-1 is a terminal device 10 used by a user (user U1) identified by the user ID "U1." In addition, in the following, when the terminal device 10-1, etc. are described without any particular distinction, they will be described as terminal device 10.

[0021] The in-store device 20 is a computer used by the manager of each store. For example, the manager of restaurant A uses the in-store device 20 to send and receive information to and from the information processing device 100. For example, the in-store device 20 is realized by a smartphone, a tablet terminal, a laptop PC, a desktop PC, a mobile phone, a PDA, or the like. The in-store device 20 transmits various information related to the store to the information processing device 100. The in-store device 20 transmits information requested by the information processing device 100 to the information processing device 100. The in-store device 20 transmits store information to the information processing device 100, including various information such as the location of the store and the state of the store's entrances and exits.

[0022] The data providing device 50 is a server that provides various types of data to the information processing device 100. For example, the data providing device 50 may provide meteorological data such as weather and temperature to the information processing device 100. The data providing device 50 may also provide event information related to the weather in the area where each store is located to the information processing device 100. For example, the data providing device 50 provides open data, which is data that is permitted for wide-open use, to the information processing device 100. For example, the data providing device 50 may be an information processing device that is managed by a local government and provides data held by the local government to an external party. The data providing device 50 may provide various types of data (information) that are permitted for use, including, but not limited to, traffic data such as road information, geospatial information, disaster prevention and mitigation information, procurement information, statistical information, and the like.

[0023] The information processing device 100 is a computer that executes processing related to providing information. The information processing device 100 is an information processing device that can communicate with various devices via a predetermined network N such as the Internet, and is realized by, for example, a server device or a cloud system. For example, the information processing device 100 is communicably connected to various other devices via the network N. The information processing device 100 executes a providing process that determines suggested information to be proposed to a user based on changes in the user's context, and provides the determined suggested information to a terminal device 10 used by the user. The information processing device 100 executes a process (also referred to as a "context estimation process") that estimates the user's context based on sensor information. The information processing device 100 executes the providing process based on the estimated user's context.

[0024] [1-2. Example of information provision processing] The flow of information processing will now be described with reference to Fig. 1. Fig. 1 shows a map MP1 that schematically illustrates the positional relationship between the terminal device 10-1 (user U1), the store SP11, and the store SP22. Fig. 1 shows an example in which the user U1 moves toward the store SP11 and enters the store SP11.

[0025] The information processing device 100 acquires sensor information SD10 from the terminal device 10-1 used by the user U1 (step S11-1). In FIG. 1, sensor detection is performed when the user U1 moves on foot in an area corresponding to the map MP1. The terminal device 10-1 transmits the sensor information SD10 based on the sensor detection to the information processing device 100. The information processing device 100 receives the sensor information SD10 from the terminal device 10-1. In FIG. 1, the information processing device 100 receives the sensor information SD10 corresponding to the movement of the user U1 from the terminal device 10-1. For example, the information processing device 100 receives the sensor information SD10 including position information, acceleration information, and temperature information during the movement of the user U1 from the terminal device 10-1. In FIG. 1, the information processing device 100 receives the sensor information SD10 including temperature information indicating that the temperature (outside air temperature, etc.) of the environment during the movement of the user U1 is low (for example, 5°C, etc.) from the terminal device 10-1.

[0026] As a result, the information processing device 100 acquires sensor information SD10 of the user U1 from the terminal device 10-1, as shown in the target information TG10. As described above, the sensor information such as the sensor information SD10 is not limited to position, acceleration, temperature, etc., but may also be information on various targets such as air pressure, sound, illuminance (brightness), etc.

[0027] Then, the information processing device 100 estimates a context corresponding to the sensor information SD10 (step S12-1). The information processing device 100 estimates a context using the sensor information SD10. In FIG. 1, the information processing device 100 estimates that the context of the user U1 at the time of detection corresponding to the sensor information SD10 is the context CN10, as indicated by the determination information TD10. That is, the information processing device 100 estimates that the first context, which is the context of the user U1 corresponding to the sensor information SD10, is the context CN10, as indicated by context #1 in the determination information TD10. For example, the context CN10 is a context corresponding to traveling on foot. Furthermore, the context CN10 may be a context corresponding to traveling on foot in a cold environment.

[0028] For example, based on the position information and acceleration information included in the sensor information SD10, the information processing device 100 estimates that the context CN10 indicates that the user U1 is traveling on foot at the time of detection corresponding to the sensor information SD10. Note that the information processing device 100 may estimate the user's means of transportation by appropriately using various methods. For example, the information processing device 100 may estimate that the user U1 is traveling on foot if the traveling speed of the user U1 indicated by the sensor information SD10 is less than a predetermined threshold, and may estimate that the user U1 is traveling by mobile object if the traveling speed of the user U1 is equal to or greater than the predetermined threshold.

[0029] For example, the information processing device 100 may use various information acquired from the terminal device 10-1 to estimate that the user U1 is moving on foot at the time of detection corresponding to the sensor information SD10. In this case, the information processing device 100 may estimate that the context at the time of detection corresponding to the sensor information SD10 is the context CN10 based on behavioral information of the user U1 acquired from the terminal device 10-1, etc. For example, the information processing device 100 may estimate that the context at the time of detection corresponding to the sensor information SD10 is the context CN10 based on behavioral information indicating content posted by the user U1 using the terminal device 10-1.

[0030] Note that the information processing device 100 may acquire context information by any method as long as it is possible to acquire information indicating a context (context information). For example, the information processing device 100 may acquire the context information from the terminal device 10-1. In this case, the terminal device 10-1 transmits the context information to the information processing device 100 in response to an operation by the user U1. The information processing device 100 receives the context information from the terminal device 10-1. The information processing device 100 may acquire information indicating a context corresponding to the sensor information SD10. In FIG. 1, the information processing device 100 may acquire, from the terminal device 10-1, information indicating that the context of the user U1 at the time of detection corresponding to the sensor information SD10 is moving on foot. For example, the information processing device 100 acquires, from the terminal device 10-1, context information including information indicating that the context corresponding to the sensor information SD10 is a context CN10 indicating moving on foot.

[0031] In FIG. 1, user U1 moves toward store SP11 and enters store SP11. Information processing device 100 acquires sensor information SD11 from terminal device 10-1 used by user U1 (step S11-2). In FIG. 1, terminal device 10-1 performs sensor detection when user U1 enters store SP11. Terminal device 10-1 transmits sensor information SD11 based on the sensor detection to information processing device 100. Information processing device 100 receives sensor information SD11 from terminal device 10-1. In FIG. 1, information processing device 100 receives sensor information SD11 corresponding to user U1's entry into store SP11 from terminal device 10-1.

[0032] Then, the information processing device 100 estimates a context corresponding to the sensor information SD11 (step S12-2). The information processing device 100 estimates the context using the sensor information SD11. In FIG. 1, the information processing device 100 estimates that the context of the user U1 at the time of detection corresponding to the sensor information SD11 is the context CN11, as indicated by the determination information TD11. For example, based on the location information included in the sensor information SD11, the information processing device 100 estimates that the context CN11 indicates that the user U1 entered the store SP11 at the time of detection corresponding to the sensor information SD11.

[0033] Note that the above is merely an example, and the information processing device 100 may estimate the context CN11 using various information. For example, the information processing device 100 may estimate that the user U1 has entered the store SP11 at the time of detection corresponding to the sensor information SD11, using various information acquired from the terminal device 10-1. In this case, the information processing device 100 may estimate that the context at the time of detection corresponding to the sensor information SD11 is the context CN11 based on behavioral information of the user U1 acquired from the terminal device 10-1, etc. The information processing device 100 may estimate that the context at the time of detection corresponding to the sensor information SD11 is the context CN11 based on behavioral information indicating that the user U1 has opened the door of the store SP11.

[0034] As described above, in Fig. 1, the information processing device 100 estimates that the second context, which is the context of user U1 corresponding to sensor information SD11, is context CN11, as shown in context #2 of decision information TD11. Thus, in Fig. 1, the information processing device 100 estimates that the context of user U1 has transitioned from context CN10 to context CN11. That is, the information processing device 100 estimates that the context of user U1 has progressed to context CN11 via context CN10.

[0035] Then, the information processing device 100 determines suggested information to be proposed to user U1 based on the transition of user U1's context from context CN10 to context CN11 (step S13). In FIG. 1, the information processing device 100 determines suggested information to be proposed to user U1 based on the transition of user U1's context from context CN10 to context CN11. For example, the information processing device 100 determines a target store (also referred to as a "target store") for suggested information to be proposed to user U1 based on the location of user U1 corresponding to context CN11, which is the second context. In FIG. 1, the information processing device 100 determines a target store for providing suggested information to user U1 using a store data group DT in which information identifying the store (store ID) is associated with store information including the location of the store and a menu of products and other items offered by the store.

[0036] For example, the information processing device 100 determines target stores for providing suggested information to user U1 by comparing the location of each store in the store data group DT with the location of user U1. The information processing device 100 determines the store closest to the location of user U1 among the stores in the store data group DT as the target store for providing suggested information to user U1. In FIG. 1, as shown in the provided information PD, the information processing device 100 determines store SP11 closest to the location of user U1 as the target store for providing suggested information to user U1.

[0037] Then, the information processing device 100 determines suggested information to be suggested to the user U1 from the offered menu provided by the target store based on the transition of the context of the user U1 from the context CN10 to the context CN11. In Fig. 1, the information processing device 100 determines, as a proposal target to be suggested to the user U1, a product (offered menu) corresponding to the transition of the context of the user U1 from the context CN10 to the context CN11, from the offered menu MN11 which is a product provided by the target store, store SP11.

[0038] For example, based on a context transition in which user U1 moves through a low-temperature environment (for example, 5°C) and enters store SP11, information processing device 100 determines a hot menu item from among the menu items MN11 provided by store SP11 as a proposal target to be proposed to user U1. In Fig. 1, information processing device 100 determines menu item MN111, which is a hot menu item from among the menu items MN11 provided by store SP11, as a proposal target to be proposed to user U1.

[0039] The information processing device 100 determines a hot drink menu item MN111 from among the provided menu items MN11 indicating a group of foods and drinks provided by the store SP11 as a proposal target to be proposed to the user U1. For example, the provided menu item MN11 includes information in which a first flag is associated with a menu item that is suitable for provision when the environment in the user's first context is cold. The information processing device 100 determines the menu item MN111, which is a menu item with the first flag attached, from among the provided menu items MN11 provided by the store SP11 as a proposal target to be proposed to the user U1. Furthermore, when there are multiple menu items with the first flag attached, the information processing device 100 may determine a menu item that the user U1 likes from among the multiple menu items with the first flag attached as a proposal target to be proposed to the user U1.

[0040] Then, the information processing device 100 provides the suggested information of the target store to the terminal device 10-1 used by the user U1 (step S14). In FIG. 1, the information processing device 100 transmits a coupon for menu MN111 of store SP11, which is the target store, to the terminal device 10-1 used by the user U1. In this way, when the user enters the warm store from a cold environment, the information processing device 100 suggests hot food and drink. Having received the coupon for menu MN111 of store SP11, the user U1 using the terminal device 10-1 orders menu MN111 using the coupon for menu MN111.

[0041] In this way, the information processing device 100 provides the terminal device 10 with the menu MN111 of the store SP11, which is the target store corresponding to the user U1, based on the transition of the context of the user U1 who uses the terminal device 10. This allows the information processing device 100 to provide appropriate information to the terminal device 10 used by the user.

[0042] As described above, the information processing device 100 proposes a menu in accordance with a context transition. For example, the information processing device 100 identifies candidate service items provided at facilities visited by the user, and determines a proposed item from the candidate service items in accordance with a context transition history up to a predetermined period after the visit. For example, the information processing device 100 identifies a menu item at a store visited, and estimates a context history up to an order, including within the store visited. Then, the information processing device 100 identifies a proposed menu item in accordance with the estimated context history. The information processing device 100 provides a coupon for the identified menu item.

[0043] [1-3. Other processing examples] The above-described process is merely an example, and the information processing device 100 may perform various processes using various information. In this regard, examples are listed below.

[0044] [1-3-1. Proposal subject] In the above example, a case where a suggestion target is determined depending on the temperature has been shown, but the information processing device 100 may determine a suggestion target using various information. For example, when the user enters a warm store from a cold environment and feels tired, the information processing device 100 may determine a warm and sweet food or drink as a suggestion target and provide the user with suggestion information indicating the suggestion target.

[0045] For example, the information processing device 100 estimates the user's fatigue level based on the user's biological information included in the sensor information. The information processing device 100 estimates the user's fatigue level based on the user's heart rate indicated by the sensor information. For example, the information processing device 100 estimates the user's fatigue level by appropriately using various techniques related to estimating (measuring) a person's fatigue level.

[0046] The information processing device 100 estimates the user's fatigue level based on the relationship between the user's behavior and the user's heart rate. If the user's heart rate indicated by the sensor information satisfies a predetermined condition, the information processing device 100 estimates that the user is fatigued. Note that the information processing device 100 may estimate the user's fatigue level by any method as long as it can estimate the user's fatigue level using biological information such as the user's heart rate.

[0047] The information processing device 100 may also estimate whether the user is hungry. For example, the information processing device 100 estimates the user's hunger level based on the user's biological information included in the sensor information. The information processing device 100 estimates the user's hunger level based on the user's blood glucose level indicated by the sensor information. For example, the information processing device 100 estimates that the user is full if the user's blood glucose level indicated by the sensor information is equal to or higher than a first threshold. For example, the information processing device 100 estimates that the user is hungry if the user's blood glucose level indicated by the sensor information is less than a second threshold that is smaller than the first threshold. For example, the information processing device 100 estimates that the user is normal if the user's blood glucose level indicated by the sensor information is less than the first threshold and equal to or higher than a second threshold.

[0048] For example, when it is estimated that the user is hungry, the information processing device 100 may determine a food menu as the suggestion target. For example, when it is estimated that the user is hungry, the information processing device 100 may determine a high-calorie food menu as the suggestion target. For example, when it is estimated that the user is hungry, the information processing device 100 may determine a food menu with calories equal to or greater than a predetermined value (e.g., 1000 kcal) as the suggestion target. For example, when it is estimated that the user is full, the information processing device 100 may determine a beverage menu as the suggestion target. For example, when it is estimated that the user is full, the information processing device 100 may determine a low-calorie beverage menu as the suggestion target. For example, when it is estimated that the user is full, the information processing device 100 may determine a beverage menu with calories less than a predetermined value (e.g., 200 kcal) as the suggestion target.

[0049] [1-3-2. Other Elements] The information processing device 100 may perform processing using various information other than the temperature of the environment. For example, the information processing device 100 may determine the timing for providing the user with suggested information based on the user's emotions. For example, the information processing device 100 may provide the user with suggested information at a timing when the user's emotional excitement meets a predetermined standard.

[0050] For example, the information processing device 100 estimates the user's emotions based on the user's biometric information included in the sensor information. For example, the information processing device 100 estimates the user's emotions based on the user's heart rate indicated by the sensor information. For example, if the user's heart rate indicated by the sensor information is equal to or greater than a first threshold, the information processing device 100 estimates that the user is in an excited state. For example, if the user's heart rate indicated by the sensor information is less than a second threshold that is smaller than the first threshold, the information processing device 100 estimates that the user is in a calm state.
