[0011] (1) Overview The drawings described in the following embodiments are schematic drawings, and the ratios of the sizes and thicknesses of the components in the drawings do not necessarily reflect the actual dimensional ratios.

[0012] An information presentation method according to one aspect of the present embodiment is a method of presenting one of a plurality of pieces of presentation information A1 (see FIG. 4) to a user 5. Here, as an example, "presentation information" includes meal information related to meals, and in particular, meal information includes information on cooking menus and combinations of cooking menus. Furthermore, meal information includes information on recipes (cooking methods) and information on take-out meals and eating out (store information on restaurants, etc.) in addition to cooking menus. Hereinafter, cooking menus and recipes, regardless of the number of menu items (whether one item or multiple items), will be collectively referred to simply as a "menu," and suggestions related to presentation information A1 will be referred to as "menu suggestions."

[0013] The presented information A1 is not limited to including dietary information about meals. The presented information A1 may include information about music, books, videos, etc. instead of meals. In this embodiment, it is assumed that the information presentation method provides dietary information for the current day, the next day, or a long period of time, such as one week or one month.

[0014] The information presentation method includes a first determination step, a first presentation step, a second determination step, and a second presentation step.

[0015] In the first determination step, a plurality of intermediate words B1 are determined based on condition information C1 (see FIG. 3B) related to a user 5 (see FIG. 1). Here, an example will be described in which the information presentation method is used by focusing on a family living in a certain house 200. That is, the information presentation method is used for a group G1 (one household) including multiple users 5 (mother 50, father 53, child 51, and grandfather 52). However, the number of users 5 is not particularly limited, and the information presentation method can be used for a single user, or for an organization or group.

[0016] The "condition information" referred to here is information (acquired information) relating to at least one of user status, inventory status, and environmental status, and this information is used to determine whether or not a predetermined condition is met. Information relating to user status is, for example, information relating to the current location (position) of user 5, and information relating to the health status of user 5, etc. Information relating to inventory status is, for example, information relating to the type of food ingredients stored in home 200 (in the freezer, refrigerator, etc.) and their expiration date (specifically, expiration date or best-before date, etc.). Information relating to environmental status is, for example, information relating to the temperature, humidity, season, etc., of the environment surrounding home 200 or the environment surrounding user 5.

[0017] In the first presentation step, a plurality of intermediate words B1 are presented to the user 5 so that the user 5 can select one or more intermediate words B1 from the plurality of intermediate words B1. In this embodiment, the output unit 25 of the presentation device 2, which corresponds to an information terminal owned (for example, carried) by the user 5, outputs (presents) the plurality of intermediate words B1.

[0018] The "information terminal" referred to here is, for example, a smartphone or a tablet terminal. It is assumed that the "presentation" is performed by screen output from a display unit 25A (see FIG. 4) including, for example, a touch panel type liquid crystal display or an organic EL (Electro-Luminescence) display. However, the presentation device 2 is not limited to a portable terminal and may be, for example, a stationary personal computer. Furthermore, the "presentation" is not limited to screen output and may be performed by audio output instead of or in addition to the screen output. For example, the presentation device 2 may be a smart speaker that applies artificial intelligence (AI) technology, a so-called AI speaker. The presentation device 2 may also be a smart TV. If the presentation device 2 is not a portable terminal, it may be installed in the kitchen or the like of the house 200.

[0019] In a second determination step, presentation information A1 corresponding to one or more intermediate words B1 selected by the user 5 is determined from the plurality of pieces of presentation information A1. In a second presentation step, the determined presentation information A1 is presented to the user 5. In the second presentation step, the determined presentation information A1 is basically presented from the same presentation device 2 that presented the plurality of intermediate words B1 in the first presentation step. As an example of the presentation information A1 (meal information), the presentation information A1 may include information (text information and image information) about a cooking menu item called "Braised Komatsuna" (see FIG. 4). The presentation information A1 may also include information (text information and image information) about the recipe (cooking method) of "Braised Komatsuna", for example.

[0020] The presentation destination in the first presentation step may be different from the presentation destination in the second presentation step. For example, the presentation in the first presentation step may be made to a smartphone owned by the user 5, and the presentation in the second presentation step may be made to a smart TV owned by the user 5. Furthermore, the presentation information A1 presented in the second presentation step is not limited to one, and may be multiple.

[0021] Here, each of the multiple intermediate words B1 is a word associated with an attribute D1 (see FIG. 3C ) related to one or more pieces of presentation information A1 among the multiple pieces of presentation information A1. The presentation information A1 (meal information) may include multiple attributes D1, such as the “ingredients” needed for the cooking menu, the “cooking time” of the cooking menu, the “temperature” of the cooking menu, and the “season (time of year)” when the cooking menu is prepared. For example, if the attribute D1 is ingredients, the intermediate word B1 includes a word indicating the name of the ingredient, such as “komatsuna (Japanese mustard spinach).” If the attribute D1 is cooking time, the intermediate word B1 includes a word associated with the cooking time, such as “time-saving” (can be made quickly). Note that while the “temperature” information in the attribute D1 has been described as the temperature of the cooked menu itself, the “temperature” information may also be the outdoor temperature appropriate for the cooking menu. For example, the attribute “temperature” of the cooking menu “hot pot” can be set to an outdoor temperature condition that causes a sudden cold sensation (e.g., when the outdoor temperature is 13 degrees Celsius or lower and the temperature is -5 degrees Celsius or higher on the day or the day before).

[0022] According to the information presentation method of this embodiment, a plurality of intermediate words B1 are determined and presented based on condition information C1 related to the user 5 (see FIG. 1 ), so that the user 5 can be presented with presented information A1 simply by selecting an intermediate word B1 of interest from the plurality of intermediate words B1. In other words, unlike Patent Document 1, the user 5 does not have to go to the trouble of thinking up and inputting a search word that corresponds to the intermediate word B1. As a result, there is an advantage in that convenience for the user 5 is improved and the intention of the user 5 is more easily reflected.

[0023] An information presentation system 100 according to another embodiment presents one of a plurality of pieces of presentation information A1 to a user.

[0024] As shown in FIG. 1, the information presentation system 100 includes a first decision unit 11, a first presentation unit 13, a second decision unit 12, and a second presentation unit .

[0025] The first determination unit 11 determines a plurality of intermediate words B1 based on the condition information C1. The first presentation unit 13 presents the plurality of intermediate words B1 to the user 5 so as to allow the user 5 to select one or more intermediate words B1 from the plurality of intermediate words B1. The second determination unit 12 determines, from the plurality of pieces of presentation information A1, presentation information A1 that corresponds to the one or more intermediate words B1 selected by the user 5. The second presentation unit 14 presents the determined presentation information A1 to the user 5.

[0026] This information presentation system 100 also has the advantage that the convenience for the user 5 is improved and the intention of the user 5 is more easily reflected.

[0027] In this embodiment, it is assumed that all of the functions of the first determination unit 11, the first presentation unit 13, the second determination unit 12, and the second presentation unit 14 are integrated and incorporated into a server 1 that can communicate with one or more presentation devices 2. However, at least some of these functions may be incorporated into a device other than the server 1. Furthermore, it is assumed that the server 1 is configured from one server device, but it may be configured from multiple server devices, and such server devices may form, for example, a cloud (cloud computing).

[0028] The information presentation system 100 of this embodiment manages, for example, historical information on intermediate words B1 selected daily by a user 5, and determines, through machine learning, multiple intermediate words B1 that are more suited to the lifestyle patterns (lifestyle habits, lifestyle rhythms) and preferences of the user 5.

[0029] (2) Details The configuration of the information presentation system 100 according to this embodiment will be described in detail below with reference to FIGS.

[0030] (2.1) Overall structure The information presentation system 100 is configured to present one of a plurality of pieces of presentation information A1 to a user 5. Here, the information presentation system 100 is configured to execute a suggestion process that suggests a "menu" in response to a request from the user 5. The information presentation system 100 includes one or more presentation devices 2 and a server 1. As described above, the focus here is on a plurality of users 5 (families) living in a certain residence 200, and the information presentation system 100 further includes a (microwave) microwave 4, which is one of the cooking appliances installed in the home, and a router 6 installed in the home. However, the information presentation system 100 is not limited to being applied to the family living in the residence 200, as long as the user requires the provision of a service of meal information (presentation information A1) related to meals.

[0031] Here, the family living in the house 200 is made up of four users 5: a mother 50, a father 53, a child 51, and a grandfather 52. As an example, the mother 50 cooks meals for the entire family every day. Therefore, the mother 50 (cook X1) is the one who primarily requests support for daily menu planning (provision of presentation information A1) from the information presentation system 100. Of course, a family member other than the mother 50 (for example, the father 53) may temporarily act as the cook X1 in place of the cook X1.

[0032] 1, in this embodiment, all members of a family (multiple users 5) each own (carry) one presentation device 2. A mother 50 owns a presentation device 2A, a child 51 owns a presentation device 2B, a grandfather 52 owns a presentation device 2C, and a father 53 owns a presentation device 2D.

[0033] As described above, each presentation device 2 is assumed to be a portable information terminal such as a smartphone. When a user 5 carrying the presentation device 2 is in the home 200, the presentation device 2 is communicatively connected to a router 6 installed in the home. Each presentation device 2 performs wireless communication with the router 6 in accordance with a standard such as Wi-Fi (registered trademark). The router 6 can also be communicatively connected to various electronic devices in the home. In this embodiment, the microwave oven 4 corresponds to one of the electronic devices capable of communicating with the router 6. Each presentation device 2 can wirelessly communicate with the microwave oven 4 via the router 6. Other electronic devices that can communicate with the router 6 include refrigerators, freezers, ovens, rice cookers, and other cooking appliances. If a Home Energy Management System (HEMS) is installed in the home 200, the HEMS controller is also communicatively connected to the router 6. The router 6 is connected to a network NT1 (see FIG. 1 ), such as the Internet. Each presentation device 2 and various electronic devices can communicate with a server 1 outside the home 200 via the router 6. Server 1 will be explained in detail in the next section.

[0034] 2, each presentation device 2 includes a communication unit 21, a control unit 22, a storage unit 23, an input unit 24, an output unit 25, and a detection unit 26. Each presentation device 2 is pre-installed with dedicated application software (hereinafter simply referred to as a "cooking application") for communicating with the microwave oven 4, the server 1, etc., and presenting a GUI (Graphical User Interface) related to meals.

[0035] The communication unit 21 is a communication interface for communicating with the range device 4, the server 1, etc. Each presentation device 2 transmits and receives data to and from the range device 4, the server 1, etc. via the communication unit 21.

[0036] The control unit 22 is configured to perform overall control of the presentation device 2, i.e., to control the communication unit 21, the control unit 22, the storage unit 23, the input unit 24, the output unit 25, and the detection unit 26. The control unit 22 can be realized, for example, by a computer system including one or more processors (microprocessors) and one or more memories. That is, the one or more processors execute one or more programs (applications) stored in one or more memories to function as the control unit 22. Here, the programs are pre-recorded in the memory of the control unit 22, but they may also be provided via a telecommunications line such as the Internet or recorded on a non-transitory recording medium such as a memory card.

[0037] The storage unit 23 is configured with a readable and writable memory. The storage unit 23 is, for example, a flash memory. The storage unit 23 is provided outside the control unit 22, but may also be provided inside the control unit 22. In other words, the storage unit 23 may be an internal memory of the control unit 22. The storage unit 23 stores various data.

[0038] The input unit 24 is a user interface that accepts input operations from the user 5, and in this case, a touch panel display (display unit 25A) attached to the presentation device 2 also functions as the input unit 24. In other words, user input is accepted by an operation (tapping operation, etc.) on the display screen 250 of the display unit 25A with the user's fingertip or the like. A microphone attached to the presentation device 2 may also function as the input unit 24 (voice input). The input unit 24 accepts user input related to the cooking app. In particular, the input unit 24 accepts an input for selecting an intermediate word B1 or presented information A1 that interests the user 5 from the above-mentioned "plurality of presented intermediate words B1" or "presented presented information A1."

[0039] The output unit 25 is a user interface that outputs (presents) various information to the user 5, and in this case, a touch panel display unit 25A attached to the presentation device 2 also functions as the output unit 25. A speaker attached to the presentation device 2 may also function as the output unit 25. The output unit 25 outputs information related to the cooking app to the user 5. In particular, the output unit 25 performs "presentation" by outputting image data and character string data related to the tag (object image) of the intermediate word B1 and the presentation information A1 from the display unit 25A, and by outputting audio data related to the intermediate word B1 and the presentation information A1 from the speaker.

[0040] The detection unit 26 is configured to detect the user situation of the user 5 carrying the device itself (presentation device 2). The detection unit 26 acquires current location information of the device itself using a satellite positioning system such as a GPS (Global Positioning System), and detects the current location (user situation) of the user 5 carrying the presentation device 2 based on the location information. The control unit 22 transmits information related to the current location of the user 5 detected by the detection unit 26 to the server 1 via the communication unit 21. The user situation detected by the detection unit 26 is not limited to the current location (coordinates) of the user 5. The detection unit 26 has a function as a thermo-hygrometer, detects the ambient temperature, and transmits information related to the temperature (environmental situation) to the server 1 via the communication unit 21.

[0041] The detection unit 26 may have a pedometer function, and the user situation may be the number of steps, calories burned, walking time, walking speed, etc. of the user 5. The detection unit 26 may also have a function to extract feature amounts from a subject in an image captured by an imaging unit (camera) attached to the presentation device 2, and the user situation may be the feature amounts from the image.

[0042] The function of the detection unit 26 is not limited to being provided in the presentation device 2, and may be provided in an external device of the presentation device 2. In this case, it is preferable that the external device be able to communicate with the presentation device 2 or the server 1 via the router 6. For example, a blood pressure monitor installed in the home may detect the blood pressure value (user status) of the user 5 and transmit the detection result to the presentation device 2 or the server 1.

[0043] User 5 can launch the cooking app on presentation device 2 and enter the user ID and password previously provided by the provider of the cooking app on the login screen to receive various services related to meal information linked to the user ID.

[0044] When user 5 launches a cooking app on presentation device 2 at any time and performs an operation input to request a menu suggestion, presentation device 2 sends a menu request signal including the user ID and the like to server 1. Triggered by receiving the menu request signal from presentation device 2, server 1 executes a personalized menu suggestion process using AI (Artificial Intelligence) technology so that a menu suitable for user 5 with that user ID can be suggested.

[0045] (2.2) Server The server 1 is installed outside the house 200. The server 1 may be operated by, for example, a person (provider) that provides a service of meal information (presentation information A1) related to meals to the user 5. As described above, the server 1 is configured, for example, by one server device.

[0046] The server 1 collects and manages various information from multiple users 5 who receive services related to the presentation information A1 via the presentation devices 2 and the like. Focusing on a family (four users 5) living in a house 200, the server 1 manages personal information (user IDs, names, addresses, telephone numbers, email addresses, etc.) of the four family members. The server 1 also manages group information indicating that the four family members (four user IDs) are organized into one group G1 (see FIG. 3A ), as well as the identification information, user IDs, and passwords of the presentation devices 2 of the four family members. The server 1 also manages location information of the house 200 and the identification information of the cooking appliances (microwave oven 4) in the house 200.

[0047] The information about the family of the house 200 described above is managed as user data M3 (see FIG. 1) by the server 1. The server 1 also provides the service of presenting information A1 to other users 5 (e.g., other houses) other than the family of the house 200, and collects information about the other users 5 and manages it as user data M3.

[0048] As shown in FIG. 1, the server 1 includes a communication unit 10, a processing unit P1, and a storage unit 17.

[0049] The communication unit 10 is a communication interface for bidirectional communication with the presentation device 2 of each user 5 and cooking appliances such as the microwave oven 4 via the network NT1.

[0050] The storage unit 17 is configured with a readable and writable memory. The storage unit 17 is, for example, a flash memory. The storage unit 17 is provided outside the processing unit P1, but may also be provided inside the processing unit P1. That is, the storage unit 17 may be an internal memory of the processing unit P1. The storage unit 17 stores various data. In particular, the storage unit 17 stores (contains) context data M1, food and drink data M2, and user data M3, as shown in FIG. 1.

[0051] The processing unit P1 is configured to perform overall control processing of the server 1. The processing unit P1 can be realized, for example, by a computer system including one or more processors (microprocessors) and one or more memories. In other words, the one or more processors execute one or more programs (applications) stored in one or more memories to function as the processing unit P1. Here, the programs are pre-recorded in the memory of the processing unit P1, but they may also be provided via a telecommunications line such as the Internet or recorded on a non-transitory recording medium such as a memory card.

[0052] 1, the processing unit P1 has a first determination unit 11 and a second determination unit 12. In other words, the processing unit P1 has a function as the first determination unit 11 and a function as the second determination unit 12. In addition, the processing unit P1 further has a first presentation unit 13, a second presentation unit 14, a third presentation unit 15, and a setting unit 16, as shown in FIG. 1. In other words, the processing unit P1 has a function as the first presentation unit 13, a function as the second presentation unit 14, a function as the third presentation unit 15, and a function as the setting unit 16.

[0053] The first determination unit 11 is configured to determine a plurality of intermediate words B1 based on condition information C1 related to the user 5 (first determination step). Upon receiving a menu request signal from the presentation device 2, the first determination unit 11 determines the plurality of intermediate words B1 based on the user ID included in the menu request signal.

[0054] Here, the intermediate word B1 will be described. The intermediate word B1 is a word associated with an attribute D1 (see FIG. 3C) related to one or more pieces of presentation information A1. FIG. 3C is a conceptual diagram of an attribute group D0 consisting of multiple attributes D1. Master information for each piece of presentation information A1 in the server 1 is stored in the food and drink data M2 in the storage unit 17 in association with information related to the multiple attributes D1 of the attribute group D0.

[0055] Specifically, for example, the master information for a cooking menu item "Yose Nabe" (presentation information A1) is associated with information such as "tofu," "Chinese cabbage," "salmon," "carrot," and "thread konnyaku" as an attribute D1 of "ingredients." The master information for "Yose Nabe" is also associated with information such as "40 minutes" as an attribute D1 of "cooking time." The master information for "Yose Nabe" is also associated with information such as "80 degrees" as an attribute D1 of "temperature." The master information for "Yose Nabe" is also associated with information such as "winter" as an attribute D1 of "season." With regard to "Yose Nabe," intermediate words B1 are words associated with the ingredients (tofu, Chinese cabbage, salmon, carrot, and thread konnyaku) of "Yose Nabe," the cooking time (40 minutes), the temperature (80 degrees), and the season (winter). The intermediate word B1 may be a word containing the name of the ingredient itself, or the word "time-saving" associated with the cooking time (40 minutes), or words such as "warm" or "hot pot" (seasonal) associated with the temperature (80 degrees) or the season (winter). As a result, the cooking menu "yosenabe" is associated with multiple intermediate words B1 such as "tofu," "time-saving," "warm," and "hot pot."

[0056] The server 1 analyzes data acquired from an external server or data related to meals posted by individuals, and periodically updates information related to the type of attribute D1, specific cooking times, temperatures, and the like.

[0057] Next, the condition information C1 will be described. The condition information C1 is acquired information that is acquired in advance or automatically in real time from the presentation device 2 of the user 5, etc. In other words, the condition information C1 is information that the user 5 does not need to input himself when requesting a menu suggestion. However, the condition information C1 may partially include information that the user 5 inputs himself on the spot. For example, if the user 5 wants to limit the number of multiple intermediate words B1 to be presented (for example, five or less), information specifying the number of intermediate words may be input on the spot as the condition information C1.

[0058] The condition information C1 includes information about the situation (context) such as the user situation, inventory situation, and environmental situation, as shown in Fig. 3B and the following Table 1. In other words, the condition information C1 is information related to the user 5 that may change daily.

[0059] [Table 1]

[0060] [User Status] The user situation may include time information, location information, health information, etc., as shown in Table 1, for example. Note that the context conditions and intermediate word examples shown in Table 1 are merely examples and are not limited to these. Furthermore, in the information presentation system 100, the intermediate words B1 corresponding to the condition examples may be changed daily based on the items selected by the user 5 (history information) to better suit individual preferences, etc. Note that the "history information" will be explained in detail in the next section.

[0061] The time information is information about the timing at which the user 5 requested a menu suggestion, and is included in the menu request signal and transmitted from the presentation device 2. Here, the time information includes information about the year, month, date, time, and day of the week, but may also be, for example, information about the time only. The time information may also be based on the time measured by a timer in the server 1, or may be information about the timing at which the menu request signal was received. The time information is used to determine whether a predetermined context condition is satisfied. Examples of predetermined context conditions for the time information include "after 7 PM" and "weekends and holidays," as shown in Table 1. If the time information satisfies at least one of the context conditions "after 7 PM" and "weekends and holidays," the first determination unit 11 may determine the words "time saving," "eating out," or "take-out meal" as intermediate words B1.

[0062] The location information is information about the current location (position) of the user 5. Here, the location information is information about the current location of the user 5 detected by the detection unit 26. The location information of the user 5 who has requested a menu suggestion is included in a menu request signal and transmitted from the presentation device 2. Location information not only about the current location of the user 5 who has requested a menu suggestion, but also about the current locations of other users 5 in the family is transmitted from the presentation devices 2 of the other users 5. For example, upon receiving the menu request signal, the server 1 transmits a signal requesting transmission of location information to the presentation devices 2 of the other users 5 in the family. The location information is then used to determine whether a predetermined context condition is satisfied. Examples of predetermined context conditions for location information include "outside the home," "more than 5 km away from the home," and "on the move (e.g., on the way home)," as shown in Table 1. If the location information satisfies at least one of the context conditions of "outside home," "more than 5 km from home," and "on the move," the first determination unit 11 may determine words such as "eating out," "take-out meal," or "relaxation" as intermediate words B1.

[0063] The health information is information about the current health condition of the user 5, and is managed in advance by the server 1, for example. The user 5 can register, change, or delete the health information at any time by, for example, starting a cooking app on the presentation device 2. The health information includes, for example, age, height, weight, eyesight, hearing, blood pressure, blood glucose level, and names of chronic illnesses, and this information is transmitted from the presentation device 2 to the server 1. As described above, some of the health information may be transmitted directly to the server 1 from an external device (for example, a blood pressure monitor). The server 1 stores and manages this information as user data M3 in the storage unit 17. Of course, if the user 5 does not wish to register information about their health condition, there is no need to input this information. The health information is then used to determine whether or not a predetermined context condition is satisfied. Examples of predetermined context conditions for the health information include "higher than a standard BMI (Body Mass Index)" and "higher than a standard blood glucose level," as shown in Table 1. The first determination unit 11 determines whether or not the health information satisfies the predetermined context condition. If at least one of the context conditions "higher than standard BMI" and "higher than standard blood glucose level" is satisfied, words such as "diet," "blood glucose level," and "low calorie" may be determined as intermediate words B1.

[0064] [Stock status] The inventory status may include inventory information about ingredients, for example, as shown in Table 1. That is, the inventory information is information about ingredients that user 5 has purchased (or received) and stored in a refrigerator or the like in house 200. Here, the inventory information is information about the ingredient's name, type (category, such as meat, seafood, beans, grains, fresh vegetables, fresh fruits, or mushrooms), storage location, remaining amount (quantity, weight, etc.), purchase date, and storage period. The storage period is assumed to be, for example, a use-by date or best-before date, but may also be a period arbitrarily set by user 5 (for example, a period set earlier than the use-by date). User 5 can register, change, or delete inventory information at any time by, for example, launching a cooking app on presentation device 2. This information is transmitted from presentation device 2 to server 1. Server 1 stores and manages this information in storage unit 17 as user data M3. Of course, if user 5 does not wish to register inventory information, there is no need to input this information. In addition, if a one-dimensional or two-dimensional code is attached to the packaging material used to package the purchased ingredients, the presentation device 2 may read the code using its imaging unit and transmit inventory information, including expiration dates, to the server 1.

[0065] The server 1 manages inventory information of ingredients stored by the user 5. When the user 5 inputs information to the presentation device 2 that they have actually cooked the presentation information A1 suggested by the information presentation system 100, the presentation device 2 transmits a feedback signal including that information to the server 1. When the user 5 cooks using the microwave 4, the microwave 4 transmits a feedback signal including cooking menu information to the server 1. The server 1 estimates the types and amounts (quantity, weight, etc.) of ingredients used from these feedback signals and updates the inventory information of the user data M3 (decreases by the amount used). Of course, the inventory information of the user data M3 may also be updated by the presentation device 2 directly receiving input from the user 5 of information indicating the amount of ingredients actually used.

[0066] The inventory information is then used to determine whether or not a predetermined context condition is satisfied. An example of a predetermined context condition for inventory information is "there is an ingredient whose expiration date is one day or less," as shown in Table 1. If there is an ingredient in the inventory information that satisfies the context condition "there is an ingredient whose expiration date is one day or less," the first determination unit 11 may determine a word, for example, "komatsuna expiration date," that includes the ingredient's name as the intermediate word B1. In other words, "komatsuna expiration date" is an intermediate word B1 corresponding to the fact that the expiration date of the komatsuna currently stored by user 5 is one day or less.

[0067] In this way, the first determination unit 11 includes a function of determining the intermediate word B1 based on the expiration date of the ingredient. In other words, the first determination step includes a determination based on the expiration date of the ingredient.

[0068] [Environmental situation] The environmental situation may include temperature information, for example, as shown in Table 1. The temperature information is temperature information for the area (e.g., AA City) where the house 200, which is the residence of the user 5, is located. The server 1 identifies the temperature information for the location area from the location information of the house 200 stored in the storage unit 17. For example, the server 1 obtains temperature information for AA City at the time of receiving the menu request signal from an external server (a server that manages weather data). The temperature information may not be temperature information for the area where the house 200 is located, but may be temperature information for the current location of the user 5 detected by the detection unit 26. The temperature information is used to determine whether a predetermined context condition is satisfied. An example of a predetermined context condition for the temperature information is "4 degrees or more lower than the temperature of the previous day," as shown in Table 1. If the temperature information satisfies this context condition, the first determination unit 11 may determine words such as "warm" or "hot pot" as the intermediate word B1.

[0069] In this embodiment, master information regarding the above-described context conditions and intermediate word examples is stored as context data M1 in the storage unit 17, as shown in Fig. 1. The context conditions and intermediate word examples are stored in a "many-to-many" correspondence with each other. The server 1 analyzes data acquired from an external server or data posted by individuals for the context data M1, collects the latest words (buzzwords, etc.), and updates the context data M1 daily (strengthening the context data M1).

[0070] The first presentation unit 13 is configured to present a plurality of intermediate words B1 to the user 5 so as to prompt the user 5 to select one or more intermediate words B1 from the plurality of intermediate words B1 (first presentation step). Specifically, the first presentation unit 13 generates a signal (context selection signal) including information about the plurality of intermediate words B1 determined by the first determination unit 11, and transmits the signal via the communication unit 10 to the presentation device 2 that is the sender of the menu request signal. For example, if a menu request signal is transmitted from the presentation device 2A of the mother 50, the first presentation unit 13 transmits the context selection signal to the presentation device 2A and causes it to be output from the output unit 25 of the presentation device 2A. In other words, as an example here, the mother 50 who owns the presentation device 2A is given the option to select one or more intermediate words B1 from the plurality of intermediate words B1.

[0071] When the communication unit 21 of each presentation device 2 (here, the presentation device 2A of the mother 50) receives the context selection signal, the control unit 22 causes the control unit 22 to display a plurality of intermediate words B1 on the display screen 250 of the display unit 25A functioning as the output unit 25, as shown in FIG. 4. In the example of FIG. 4, three intermediate words B1, namely, "time saving," "relaxation," and "komatsuna deadline," are presented. In the example of FIG. 4, the three intermediate words B1 are displayed as circular or elliptical tags. The first tag B11 indicates the intermediate word B1, "time saving." The second tag B12 indicates the intermediate word B1, "komatsuna deadline." The third tag B13 indicates the intermediate word B1, "relaxation." For each of the first tag B11 to the third tag B13, the corresponding intermediate word B1 can be selected by receiving a tap operation with the fingertip or the like of the user 5.

[0072] It is preferable that the presentation device 2 outputs, from the output unit 25, a message (character string data or voice data) prompting the user to select one or more intermediate words B1 from the three intermediate words B1.

[0073] The first tag B11 to the third tag B13 all have different area sizes displayed on the display screen 250. In the example of Fig. 4, the area size of the second tag B12 is the largest, followed by the area size of the first tag B11, and the area size of the third tag B13 is the smallest. The information presentation system 100 of this embodiment sets the area size of the corresponding tag to be larger for intermediate words B1 that are estimated to be of greater interest to the user 5 who is the sender of the menu request signal.

[0074] Specifically, the first determination unit 11 determines an index called a "recommendation level" for each of the determined intermediate words B1, and the first presentation unit 13 transmits the result related to the index together with the context selection signal. The "recommendation level" may be an absolute index for each intermediate word B1, or a relative index among the multiple intermediate words B1. The "recommendation level" is determined, for example, by mutually determining the degree to which the condition information C1 of the user 5 matches the context condition and the history information of past selections by the user 5 in the user data M3 stored in the storage unit 17. If the user 5 imposes a limit on the number of multiple intermediate words B1 to be presented, for example, to five or less, and the number of applicable intermediate words B1 is six or more, the first presentation unit 13 presents only the top five intermediate words B1 with the highest "recommendation levels."

[0075] The control unit 22 of the presentation device 2 determines the area size of each tag based on the "recommendation level" included in the context selection signal, and displays it on the display screen 250. It is not essential to change the area size of the tag according to the "recommendation level", and the area sizes of the first tag B11 to the third tag B13 may all be the same.

[0076] When the user 5 finds an intermediate word B1 of high interest among the multiple intermediate words B1 displayed on the display screen 250, the user 5 taps the tag corresponding to the intermediate word B1 with a fingertip or the like. In the example of FIG. 4 , the first tag B11 and the second tag B12 are selected by tapping (see the dotted hatching of the presentation device 2 in the center of FIG. 4 ), but the number of tags selected may be only one or all. If the user 5 cannot find a word of interest among the multiple intermediate words B1 displayed on the display screen 250, the user 5 taps an object area (not shown in FIG. 4 ) for requesting re-presentation of the intermediate words. The information presentation system 100 then accepts the re-presentation request. When the server 1 receives a signal related to the re-presentation request from the presentation device 2, the first determination unit 11 extracts an intermediate word B1 that is different from the multiple intermediate words B1 previously presented.

[0077] When the user 5 selects one or more intermediate words B1 from the plurality of intermediate words B1, the control unit 22 of the presentation device 2 generates a signal (food and drink request signal) indicating the selected intermediate words B1 and transmits it to the server 1 via the communication unit 21. When the server 1 receives the food and drink request signal, the second determination unit 12, which will be described later, determines the presentation information A1. The processing unit P1 stores the selection results of the user 5 (including re-presentation requests), that is, the intermediate words B1 in which the user 5 showed interest (selected) and the intermediate words B1 in which the user 5 did not show interest (not selected), as history information (user data M3) in the storage unit 17. The processing unit P1 then reflects the selection results of the user 5 in determining the intermediate words B1 from the next time onwards.

[0078] The second determination unit 12 is configured to determine, from among the multiple pieces of presentation information A1, presentation information A1 corresponding to one or more intermediate words B1 selected by the user 5 (second determination step). Specifically, when the second determination unit 12 receives a food and drink request signal indicating the intermediate word B1 selected by the user from the presentation device 2 via the communication unit 10, the second determination unit 12 references master information called food and drink data M2 in the storage unit 17 and extracts presentation information A1 corresponding to the intermediate word B1. As shown in Table 2 below, the food and drink data M2 is stored in the storage unit 17 in a "many-to-many" correspondence between cooking menu names and corresponding intermediate words B1. Furthermore, in the food and drink data M2, each menu name is stored in association with the necessary ingredients, including the amount. Although not described here, in the food and drink data M2, each menu name is also stored in association with a recipe (cooking method). In other words, the dietary information in this embodiment includes information related to cooking menus. The food and drink data M2 is also associated with cooking appliances required to cook each menu item, and for example, one of the cooking appliances corresponds to the microwave 4. The microwave 4 also manages information related to the food and drink data M2, and when a user 5 uses the microwave 4 to cook a certain menu item, the information is sent directly from the microwave 4 to the server 1.

[0079] [Table 2]

[0080] The second determination unit 12 extracts, from the food and drink data M2 in the storage unit 17, presentation information A1 (menu) including menu names corresponding to one or more intermediate words B1 selected by the user 5. Here, because the user 5 has selected two intermediate words B1, "time saving" and "Komatsuna expiration date" on the presentation device 2, one or more menu names associated with both of these two intermediate words B1 may be selected.

[0081] Specifically, in the food and drink data M2, the intermediate word B1 "time-saving" is associated with other cooking menu items such as "salmon porridge," "tamagoyaki sandwich," and "oyakodon" in addition to "komatsuna expiration date." Furthermore, in the food and drink data M2, the intermediate word B1 "komatsuna expiration date" is associated with other cooking menu items such as "komatsuna garlic stir-fry" in addition to "komatsuna blanched." In this case, the second determination unit 12 selects "komatsuna blanched," which is associated with both "time-saving" and "komatsuna expiration date." Thus, the second determination unit 12 includes a function for determining a cooking menu based on the expiration date of ingredients. In other words, the second determination step includes a determination based on the expiration date of ingredients.

[0082] Similarly, in the example of Table 2, if user 5 selects two intermediate words B1, "warm" and "hot pot," on presentation device 2, a menu name (such as Yosenabe) that corresponds to both of these two intermediate words B1 may be selected.

[0083] The second presentation unit 14 is configured to present the determined presentation information A1 to the user 5 (second presentation step). Specifically, the second presentation unit 14 generates a signal (a menu presentation signal) including information about one or more pieces of presentation information A1 determined by the second determination unit 12 (here, the menu name "Braised Komatsuna," necessary ingredients, a recipe, an image of the cooking menu, etc.). The second presentation unit 14 then transmits the menu presentation signal via the communication unit 10 to the presentation device 2 that is the sender of the food and drink request signal. For example, if a food and drink request signal is sent from the presentation device 2A of the mother 50, the second presentation unit 14 transmits the menu presentation signal to the presentation device 2A and causes it to be output from the output unit 25 of the presentation device 2A. The image of the cooking menu may be an image prepared in advance by the provider who operates the server 1, or may be a menu image created by an individual and posted to the server 1.

[0084] When the communication unit 21 of each presentation device 2 (here, presentation device 2A of mother 50) receives the menu presentation signal, the control unit 22 causes presentation information A1 to be displayed on the display screen 250 of the display unit 25A, as shown in the presentation device 2 on the right side of FIG. 4. In the example of FIG. 4, the presentation information A1 displays the menu name (character string data) of "Braised Komatsuna," an image (image data) of the menu, and information about the necessary ingredients (character string data). Note that tapping on the display field displaying the necessary ingredients transitions to a screen displaying more detailed information (e.g., recipe). In the example of FIG. 4, only one piece of presentation information A1 is displayed (the dish "Braised Komatsuna"); however, multiple pieces of presentation information A1 may be displayed. Furthermore, the presentation information A1 may further include information about the salt content, calories, and nutritional components of the cooking menu, as well as information about the cooking appliance (e.g., microwave 4) to be used.

[0085] The information presentation system 100 of this embodiment accepts a selection of the presentation information A1, for example, when the user 5 taps with a fingertip or the like within a predetermined area displaying one or more pieces of presentation information A1 on the display screen 250. That is, if there is a menu that the user 5 is interested in (for example, a menu that the user wants to cook) among the one or more presented menus, the user 5 selects that menu. With this selection, the information presentation system 100 accepts that the user 5 will now cook that menu (final selection for the presentation information A1).

[0086] The presentation device 2 transmits a signal (feedback signal) including the selection result to the server 1. When the processing unit P1 of the server 1 receives the feedback signal from the presentation device 2 via the communication unit 10, it determines that the user 5 has actually cooked the menu item based on the selection result. The processing unit P1 then estimates the types and amounts (quantity, weight, etc.) of ingredients that can be used in the menu item, and updates the inventory information in the user data M3 (decreases the inventory information by the amount that can be used). The processing unit P1 also stores the selection result of the user 5, i.e., the presented information A1 in which the user 5 showed interest (selected) and the presented information A1 in which the user 5 did not show interest (not selected), as history information (user data M3) in the storage unit 17. In other words, just like the selection result for the intermediate word B1, the processing unit P1 reflects the selection result for the presented information A1 in determining the intermediate word B1 from the next time onwards.

[0087] It is preferable that the authority to make the "final selection" for the presentation information A1 be given only to the cook X1 (e.g., mother 50) who actually cooks. Therefore, in the information presentation system 100, a cook flag indicating that the user is cook X1 can be set for the user ID in the user data M3 stored in the storage unit 17. The processing unit P1 of the server 1 determines whether a cook flag is assigned to the user ID of the sender of the feedback signal, and only if the cook flag is assigned, it is considered that the user 5 actually cooked the menu. If the feedback signal is sent from a user ID to which a cook flag is not assigned, the server 1 notifies this fact via the presentation device 2.

[0088] The third presentation unit 15 is configured to present a method for preserving a specific ingredient when the user 5 exhibits behavior that denies consumption of the specific ingredient (third presentation step). For example, in the above example, let's assume that the expiration date of komatsuna, one of the ingredients stored by the user 5, is one day or less, and the first presentation unit 13 presents the intermediate word B1 including "komatsuna expiration date" among the multiple intermediate words B1. However, if the user 5 does not select "komatsuna expiration date" but selects another intermediate word B1, the second presentation unit 14 is likely to present a cooking menu (presentation information A1) that does not use komatsuna. As a result, even though the expiration date of the komatsuna is approaching, the cook X1 (e.g., mother 50) is likely to ultimately select a cooking menu that does not use komatsuna.

[0089] Furthermore, if User 5 selects intermediate words B1 such as "eating out" or "prepared meals," there is a high possibility that User 5 will eat out or purchase pre-cooked food (prepared meals, etc.) outside, even though the expiration date of the komatsuna is approaching. As a result, there is a high possibility that User 5 will take actions (eating out, eating prepared meals) that will prevent User 5 from consuming komatsuna, even though the expiration date of the komatsuna is approaching.

[0090] The third presentation unit 15 presents a method for preserving the food item (specific food item) in this state. Specifically, for example, information such as washing komatsuna (Japanese mustard spinach) that is approaching its expiration date, cutting it into small pieces, and freezing it is presented to the presentation device 2 of the user 5. The timing of presenting the preservation method is not particularly limited, but for example, the preservation method is presented after the user 5 makes a final selection for the presentation information A1. Information on the preservation method is stored in the storage unit 17 as food and drink data M2 in association with each food item. The information presentation system 100 also urges the user to preserve the komatsuna by presenting the preservation method. Note that the information presentation system 100 may only urge the user to preserve the food item without presenting the preservation method (outputting a message urging the user to preserve the food item). Furthermore, since some types of food items are difficult to preserve (for example, eggs or dairy products), if the information presentation system 100 determines that such food items are likely to be past their expiration date, it may output a message urging the user to dispose of the food item.

[0091] In this way, when the user 5 exhibits behavior that disapproves of consuming an ingredient, the third presenter 15 presents a method for preserving the ingredient, thereby improving convenience.

[0092] The setting unit 16 is configured to set a group G1 (see FIG. 3A) including a plurality of users 5 (setting step). The presentation device 2 is capable of receiving an operation input for linking the family members of the user 5 (mother 50, father 53, children 51, and grandfather 52) as one group G1 through the cooking app. When the presentation device 2 receives the operation input related to the group setting, it transmits information related to the group setting to the server 1. When the setting unit 16 receives the information related to the group setting from the presentation device 2, it stores the group setting as user data M3 in the storage unit 17. The group G1 is linked by the user ID of the target person.

[0093] In this embodiment, when a menu request signal is received from the presentation device 2 of a user 5 for whom a group setting has been made, at least one of the first presentation unit 13 and the second presentation unit 14 can present information in units of groups G1. In other words, at least one of the first presentation step and the second presentation step presents information in units of groups G1. In this way, the information presentation system 100 can present information in units of groups G1, making it easy to present information to multiple users 5 (for example, families).

[0094] Here, the setting unit 16 is configured to individually enable or disable the presentation of the intermediate word B1 for each group G1 and the presentation of the presentation information A1. For example, assume that the presentation of the intermediate word B1 for each group G1 is set to "enabled," while the presentation of the presentation information A1 for each group G1 is set to "disabled." When the cook X1 (mother 50) performs an operation to transmit a menu request signal from the presentation device 2A, multiple intermediate words B1 are presented not only on the presentation device 2A of the mother 50 but also on the presentation devices 2 of the other family members (father 53, children 51, and grandfather 52). As a result, each family member can select an intermediate word B1 that interests them, and the presentation information A1 more easily reflects the opinions of all family members. In this case, the first determination unit 11 may determine the multiple intermediate words B1 based on the condition information C1 of all family members or the condition information C1 of one representative family member (e.g., cook X1). Note that, since the presentation of the presentation information A1 is "invalid," it is only targeted at the presentation device 2A of the mother 50 who is the cook X1. Of course, if the presentation of the presentation information A1 by group G1 is also set to "valid," the presentation information A1 will be presented not only to the presentation device 2A of the mother 50 but also to the presentation devices 2 of other family members.

[0095] However, even if the presentation of the presentation information A1 by group G1 is set to "enabled," it is preferable that the authority to make the "final selection" for the presentation information A1 be given only to the cook X1 (e.g., mother 50) who actually cooks, as described above. In other words, it is preferable that the authority to select the presentation information A1 presented in the second presentation step be given only to a predetermined user 5 within the group G1. In this case, when a performer (e.g., cook X1) who performs a specific action based on the presented presentation information A1 and non-performers who do not perform the action coexist within the group G1, convenience can be improved by giving that authority only to the performer.

[0096] (2.3) Reflection of historical information As described above, in the information presentation system 100 of this embodiment, the intermediate words B1 corresponding to the example conditions can be changed daily based on the items selected by the user 5 (history information) so as to better suit individual preferences, etc. The history information of the user 5 also corresponds to one of the "user situations" described above. In other words, the condition information C1 includes history information. The history information includes a history of multiple intermediate words B1 previously presented to the user 5 by the first presentation unit 13 (first presentation step).

[0097] Furthermore, in this embodiment, the history information includes history of one or more intermediate words B1 selected in the past by the user 5. That is, the information presentation system 100 manages history information of intermediate words B1, etc. selected by the user 5 on a daily basis.

[0098] Furthermore, in this embodiment, the history information includes a history of actions taken by the user 5 who previously received the presented information A1 on the second presentation unit 14 (second presentation step). Specifically, the history information includes a history of presented information A1 that the user "finally selected" (or viewed instead of selected) by tapping on the presentation device 2, and may also include a history of presented information A1 that the user "did not select." The history information also includes a history of cooking a certain cooking menu (which does not necessarily match the presented information A1) using the microwave 4, and may include a history based on information directly received from the microwave 4. In other words, the above "actions" correspond to selection, viewing, and cooking (execution).

[0099] The history information also includes previously acquired information about the user status, inventory status, and environmental status. For example, the past user status can be used to estimate the lifestyle patterns (lifestyle habits, lifestyle rhythms) of the user 5.

[0100] The processing unit P1 of the information presentation system 100 further includes a learning unit 18 (see FIG. 1 ) that performs, for example, unsupervised learning based on the history information accumulated daily. The learning unit 18 analyzes the structure and characteristics of the history information and performs clustering, etc., to generate a model for each user 5 (or for each group G1). The first determination unit 11 determines multiple intermediate words B1 that better suit the lifestyle patterns and preferences of the user 5 by taking into account the model in addition to the current situation (context) at the time the menu request signal is received. The "daily accumulated history information" here may include not only the history information of the user 5 who requested the menu suggestion, but also the history information of other users 5 in the group G1 to which the user 5 belongs, and the history information of users 5 other than the user 5 in the house 200.

[0101] Examples of characteristics possessed by history information include a strong tendency to select low-calorie or low-salt menus due to weight or blood pressure concerns, a strong tendency to have a light dinner, and a strong tendency to get home late, after 9 p.m. Other examples include a strong tendency to prefer cooking hotpots in the winter, a tendency to not be very good at managing the expiration dates of ingredients and therefore have a lot of ingredients that are approaching their expiration date, and a tendency to eat out a lot on weekends and therefore not likely to cook for oneself. In the information presentation system 100, such characteristics are likely to be reflected in the determination of intermediate words B1.

[0102] In this manner, in the present embodiment, the intermediate words B1 are determined based on the condition information C1 including the history information. Therefore, the lifestyle patterns, preferences, and the like of the user 5 are more likely to be reflected in the intermediate words B1, and as a result, the presented information A1 that more easily reflects the intention of the user 5 is more likely to be presented.

[0103] At least one of the first determination unit 11 and the second determination unit 12 preferably determines the intermediate word B1 and the presented information A1 based on the expiration date (of the ingredients) and the lifestyle pattern of the user 5. In other words, at least one of the first determination step and the second determination step preferably includes a determination based on the expiration date and the lifestyle pattern of the user 5. Specifically, for example, if a certain user 5 eats out or eats home often and tends not to cook much, or tends to get home late, there is a high possibility that the expiration date will be reached without the ingredients being consumed. In other words, the cooking frequency on a weekly basis, for example, may differ depending on the user 5. Therefore, the information presentation system 100 adjusts the timing for promoting ingredient consumption according to the cooking frequency (lifestyle pattern of the user 5) based on the history information of each user 5.

[0104] As described above, the information presentation system 100 analyzes the lifestyle pattern of the user 5 from the history information. For the user 5 who cooks relatively infrequently, the information presentation system 100 presents intermediate word B1 and presented information A1 related to ingredients whose expiration date is approaching well in advance of the expiration date. For example, one of the context conditions in Table 1, "ingredients with an expiration date of one day or less are present," can be presented two days earlier by applying the condition "ingredients with an expiration date of three days or less" to the user 5 who cooks relatively infrequently. In this case, meal suggestions can be made that take into consideration the lifestyle pattern of the user 5 as well as the expiration date of the ingredients.

[0105] (2.4) Presenting the list of ingredients Some users 5 may plan their menu for a week in advance to some extent and purchase ingredients for that week's menu all at once. Therefore, the information presentation system 100 of this embodiment allows users 5 to specify the number of meals for which they wish to receive suggestions. In other words, the presentation information A1 is not limited to information about a single meal, but may include information about two or more meals. Here, "one meal" refers to, for example, one of breakfast, lunch, dinner, and snacks per day. However, "one meal" may also refer to a meal on a daily basis. Instead of specifying the "number of meals," a "period (e.g., two days or one week)" may be specified. For example, a period may be specified based on calendar information, such as "March 1st to March 10th." The calendar information, together with event information and the like, is stored in the storage unit 17 for each user 5 and managed as user data M3. Each user 5 can view their own calendar information via the presentation device 2. For example, the user 5 can view menus they have cooked in the past in the form of a calendar (e.g., a cooking menu for February 1st: Yosenabe, etc.). The calendar information can also include scheduled events (for example, a planned date for eating out, a planned date for the father 53 to go on a business trip, a planned date for the child 51 to attend a sports day, etc.) as schedule information. This schedule information also corresponds to one of the "user situations" in the condition information C1 when the first determination unit 11 determines the intermediate word B1.

[0106] When the server 1 receives information specifying the number of meals for which suggestions are requested from the presentation device 2, the second presentation unit 14 presents presentation information A1 related to the number of meals corresponding to the number. Here, the second presentation unit 14 is configured to present, as presentation information A1, ingredient lists corresponding to two or more meals all at once (second presentation step).

[0107] Here, the server 1 may receive a request from the user 5 for re-presentation of the presentation information A1, for example, the day after or several days after presenting the presentation information A1 corresponding to a week's worth of meals. However, the situation (context) of the user 5 changes daily, and the inventory of ingredients purchased in bulk for a week will decrease with daily cooking. In response to this, the information presentation system 100 of this embodiment is configured to update the ingredient list (presented collectively) in accordance with changes in the condition information C1. Therefore, if the condition information C1 may change daily, it is possible to present an ingredient list in a format that follows the changes. In particular, it is possible to suggest the best menu that can be prepared using the ingredients remaining at the time of receiving the request for re-presentation of the presentation information A1.

[0108] The ingredient list is preferably updated in accordance with the selection results of the user 5 in response to past presentations of presentation information A1. In this case, an ingredient list that better reflects the lifestyle patterns and preferences of the user 5 can be presented.

[0109] (2.5)Priority In this embodiment, it is possible to set priorities for multiple users 5 in group G1. When priorities are set, the first determination unit 11 is configured to determine multiple intermediate words B1 based on the condition information C1 related to the users 5 with high priorities in the group G1. In other words, priorities are set for the multiple users 5 in group G1, and in the first determination step, multiple intermediate words B1 are determined based on the condition information C1 related to the users 5 with high priorities.

[0110] The priority of group G1 is set as a priority flag from "1" to "3" as shown in Table 3 below, for example.

[0111] [Table 3]

[0112] In the example of Table 3, a set of a first identifier and a second identifier constitutes the user ID of each user 5. The first identifier is a unique ID of the group G1, and the second identifier is a unique ID that distinguishes family members within the group G1. The priority flag has a value of "1" indicating the highest priority, followed by "2" and then "3" indicating the lowest priority. That is, in the example of Table 3, the highest priority is assigned to the user ID of the child 51. Furthermore, the information presentation system 100 of this embodiment also allows priority conditions to be set. The user 5 can input a priority flag and priority conditions by operating the presentation device 2.

[0113] For example, the first determination unit 11 determines the intermediate word B1 based on the condition information C1 related to the child 51 who has the highest priority in the group G1, that is, by prioritizing the lifestyle pattern and preferences of the child 51. In particular, since the priority condition for the child 51 is set to "time to return home," the first determination unit 11 estimates the time to return home from the current location of the child 51, and includes, for example, the intermediate word B1 associated with the attribute D1 of a meal that can be cooked around that time to return home.

[0114] The first determination unit 11 also determines the intermediate word B1 based on the condition information C1 related to the grandfather 52, who has the next highest priority in the group G1, that is, by prioritizing the lifestyle patterns and preferences of the grandfather 52 after the children 51. In particular, since the priority condition for the grandfather 52 is set to "blood sugar level," the first determination unit 11 includes the intermediate word B1 associated with the attribute D1 of a diet that reduces carbohydrates if the blood sugar level (health information) satisfies a predetermined context condition.

[0115] Since priority can be set in this way, the condition information C1 related to the user 5 with high priority is more likely to be reflected in the multiple intermediate words B1.

[0116] The presentation device 2 is capable of outputting a list of which priority has been set for which person in group G1 on the display screen 250 in response to an operational input from the user 5, as shown in Table 3. Therefore, each user 5 can easily view the current priority settings for group G1.

[0117] (2.6) Operation explanation The operation of the information presentation system 100 in this embodiment will be briefly described below with reference to Fig. 5. Note that the order in the following description of the operation is merely an example and is not particularly limited.

[0118] In the house 200, the mother 50, who is the cook X1, starts a cooking app on the presentation device 2A and logs in by entering her user ID and password. Furthermore, the mother 50 performs an operation input via the cooking app to request, for example, a menu suggestion for tonight's dinner (step S1). In response to the operation input from the mother 50, the presentation device 2A transmits a menu request signal to the server 1 (step S2).

[0119] When the server 1 receives the menu request signal, it requests and acquires necessary information (such as current location) from the presentation devices 2 of all users 5 in the group G1 linked to the user ID at that time. Based on the condition information C1, the server 1 then determines multiple intermediate words B1 (first determination step: step S4). As shown in FIG. 1, the mother 50, child 51, and grandfather 52 of the four family members are at home, while the father 53 is out working. Based on the father 53's current location, the server 1 infers that he is currently at work. Consequently, the intermediate words B1 may include words related to the father 53 being out.

[0120] When the server 1 determines the plurality of intermediate words B1, it generates a context selection signal and transmits it to the presentation device 2A, causing the presentation device 2A to present the plurality of intermediate words B1 to the mother 50 (first presentation step: step S5).

[0121] When the presentation device 2A receives the context selection signal, it displays a plurality of intermediate words B1 on the display screen 250 of the display unit 25A (step S6). When the presentation device 2A receives a selection of a plurality of intermediate words B1 through a tap operation or the like from the mother 50 (step S7), it generates a food and drink request signal indicating the selected intermediate word B1 and transmits it to the server 1 (step S8).

[0122] When the server 1 receives the food and drink request signal, it refers to the food and drink data M2 and determines the presentation information A1 corresponding to the intermediate word B1 selected by the user 5 (second determination step: step S9). The server 1 generates a menu presentation signal including information on the determined presentation information A1 (here, "boiled komatsuna") and transmits it to the presentation device 2A, which then presents the presentation information A1 to the mother 50 (second presentation step: step S10).

[0123] When the presentation device 2A receives the menu presentation signal, it displays the presentation information A1 on the display screen 250 of the display unit 25A (step S11). When the mother 50 decides to cook the proposed presentation information A1 for tonight's dinner, she makes a "final selection" by tapping or the like (step S12).

[0124] The presentation device 2A transmits a feedback signal including the selection result to the server 1 (step S13). When the mother 50 performs cooking using the microwave 4 for the presentation information A1 that she has finally selected (step S14), the microwave 4 transmits a feedback signal including the cooking result to the server 1 (step S15).

[0125] When the server 1 receives the feedback signals from the presentation device 2A and the microwave 4, it estimates the types and amounts (quantity, weight, etc.) of ingredients that can be used in the menu based on the selection results and cooking results, and updates the inventory information in the user data M3 (step S16). Also, at this timing, the learning unit 18 updates the (machine learning) model to take into account the selection results and cooking results.

[0126] As described above, according to the information presentation system 100 of this embodiment, a plurality of intermediate words B1 are determined and presented based on the condition information C1 related to the user 5, so that the presented information A1 is presented to the user 5 simply by selecting an intermediate word B1 of interest from the plurality of intermediate words B1. In other words, unlike Patent Document 1, the user 5 does not have to go through the trouble of thinking up and inputting a word equivalent to the intermediate word B1. As a result, there is an advantage that convenience for the user 5 is improved and the intention of the user 5 is more easily reflected.

[0127] Furthermore, compared to the initial stage of use of the information presentation system 100, the more frequently the intermediate words B1 and the presented information A1 are selected due to daily requests for menu suggestions, the more likely it is that intermediate words B1 that better suit the lifestyle patterns and preferences of the user 5 will be presented through the learning unit 18. In particular, the cook X1 may not fully grasp the current situations (contexts) of the other users 5 in the group G1 in detail, and in this respect too, the information presentation system 100 can present intermediate words B1 and presented information A1 that take the situations of the other users 5 into consideration.

[0128] (3) Variations The above embodiment is merely one of various embodiments of the present disclosure. The above embodiment can be modified in various ways depending on the design, etc., as long as the object of the present disclosure can be achieved. Furthermore, functions similar to those of the information presentation system 100 according to the above embodiment may be embodied in an information presentation method, a computer program, a non-transitory recording medium on which a computer program is recorded, or the like.

[0129] Modifications of the above embodiment are listed below. The modifications described below can be applied in appropriate combinations. Hereinafter, the above embodiment may also be referred to as a "basic example."

[0130] The information presentation system 100 of the present disclosure includes a computer system. The computer system is primarily composed of a processor and memory as hardware. The functions of the information presentation system 100 of the present disclosure are realized by the processor executing a program stored in the memory of the computer system. The program may be pre-stored in the memory of the computer system, provided via a telecommunications line, or provided in a non-transitory recording medium readable by the computer system, such as a memory card, optical disk, or hard disk drive. The processor of the computer system is composed of one or more electronic circuits including a semiconductor integrated circuit (IC) or a large-scale integrated circuit (LSI). The integrated circuits, such as ICs and LSIs, are referred to by different names depending on the degree of integration, and include integrated circuits called system LSIs, very large-scale integrations (VLSIs), and ultra-large-scale integrations (ULSIs). Furthermore, field-programmable gate arrays (FPGAs), which are programmable after the LSI is manufactured, or logic devices capable of reconfiguring the connections within the LSI or the circuit partitions within the LSI can also be used as processors. The electronic circuits may be integrated into one chip or distributed across multiple chips. The chips may be integrated into one device or distributed across multiple devices. The computer system referred to here includes a microcontroller having one or more processors and one or more memories. Therefore, the microcontroller is also composed of one or more electronic circuits including a semiconductor integrated circuit or a large-scale integrated circuit.

[0131] Furthermore, it is not essential that multiple functions of the information presentation system 100 be concentrated in one housing. For example, the components of the information presentation system 100 may be distributed across multiple housings. Conversely, multiple functions of the information presentation system 100 may be concentrated in one housing. Furthermore, at least some of the functions of the information presentation system 100, for example, some of the functions of the information presentation system 100 may be realized by the cloud (cloud computing) or the like.

[0132] In the basic example, a plurality of intermediate words B1 are displayed as circular and elliptical tags on the display screen 250 of the display unit 25A of the presentation device 2. However, as shown in Fig. 6, a plurality of intermediate words B1 may also be displayed in a list format. Even in the list format, it is preferable that the intermediate words B1 are displayed in descending order of "recommended level" from the top.

[0133] In the basic example, one piece of presentation information A1 is displayed on one screen. However, as shown in FIG. 7, two pieces of presentation information A1 (boiled komatsuna and hot pot) may be displayed on one screen. Furthermore, the presentation information A1 may be displayed together with the intermediate word B1 so that the user 5 can understand the intermediate word B1 that was the factor that caused the server 1 to determine the presentation information A1. From the example in FIG. 7, it can be easily understood that "boiled komatsuna" was determined based on the intermediate word B1, "time saving," selected by the user 5, and that "hot pot" was determined based on the intermediate word B1, "warm," selected by the user 5.

[0134] In the basic example, the meal information (presentation information A1) was information about cooking menus and recipes. However, the meal information may also be information about eating out or ready-made meals. Specifically, when user 5 selects "eating out" or "ready-made meals" as intermediate word B1, information presentation system 100 may present, as presented information A1, store information about supermarkets, restaurants, and other stores in the area surrounding house 200. In this case, server 1 acquires and stores map information about stores such as supermarkets and restaurants from an external server, and searches for stores in the area surrounding house 200 or in an area along the route from house 200 to father 53's workplace. If server 1 acquires information about supermarket sales or restaurant point awards from the external server, it presents the information as intermediate word B1, such as "sales" or "point awards." If user 5 shows interest, server 1 proposes, as presented information A1, the store name and location information, as well as information about menus eligible for point awards (or ingredients or side dishes on sale, etc.).

[0135] In the basic example, the right to select multiple intermediate words B1 is given only to the mother 50 who owns the presentation device 2A. However, a context selection signal may also be transmitted to the presentation devices 2 of other users 5 in the group G1, thereby giving the other users 5 the right to select multiple intermediate words B1. Furthermore, each presentation device 2 may output a chat window on the display screen 250 so that the group G1 can discuss which intermediate word B1 and presentation information A1 to select from the multiple presented intermediate words B1 and presentation information A1. In this case, the information presentation system 100 can also provide a platform for holding family meetings regarding cooking menus.

[0136] In the basic example, the mother 50 was the cook X1, but if another user 5 in the group G1, for example, the father 53, temporarily becomes the cook X1, he or she will request menu presentation using his or her own presentation device 2D. In this case, the information presentation system 100 basically causes the presentation device 2D to present the intermediate word B1 and the presentation information A1.

[0137] In the basic example, mother 50, who is cook X1, requests a menu suggestion from presentation device 2 while at home. For example, mother 50, who is cook X1, may request a menu suggestion from presentation device 2 while out (e.g., while shopping). In this case, it may be possible to set the user situation related to the current location of user 5 to have a significant influence on the determination of intermediate word B1.

[0138] In the basic example, the information presentation system 100 determines and presents the intermediate word B1 when it receives a request for a menu proposal from the user 5 (mother 50). However, the information presentation system 100 may automatically start the process of determining the intermediate word B1 at a predetermined time, for example, and notify (present) the intermediate word B1 by push notification or the like.

[0139] In the basic example, the presentation information A1 includes meal information related to meals. The presentation information A1 may include information related to music, books, videos, etc. instead of meals.

[0140] (4) Specific examples of implementation A more specific example of the above embodiment will now be described.

[0141] (4.1) Construction of specific examples Below, a specific example of meal suggestions, which are suggestions about meals, will be described as presented information. Note that meal suggestions are a concept that includes presenting a menu or a recipe for a menu consisting of multiple menus and suggesting meals that require cooking, as well as suggesting meals that do not require cooking, such as eating out or eating at home. Note that in the following description, components that are considered to be substantially equivalent to those in the above embodiment will be assigned the same reference numerals, and the above description will be referred to, and the description here may be omitted.

[0142] In the specific example described below, a server 1a shown in Fig. 8 is used instead of the server 1 in Fig. 1. Fig. 8 is a block diagram showing the functional configuration of a presentation system according to the specific example of the embodiment. Note that Fig. 8 does not show the configuration of the server 1 described above, but the server 1a will be described as having the same configuration as the server 1 described above.

[0143] Specifically, the server 1a differs from the server 1 in that it includes an acquisition unit 19. The acquisition unit 19 is a processing unit for acquiring user information related to the user 5, and is realized by executing a predetermined program using a processor and a memory. For example, the acquisition unit 19 is realized as one function of the processing unit P1. The acquisition unit 19 acquires information related to the user 5, for example, from a detection unit provided in various devices. For this purpose, the acquisition unit 19 is communicatively connected to the detection units provided in the various devices via, for example, the communication unit 10. The information acquired here will be described in detail later. The detectors from which the acquisition unit 19 acquires information may include the detection unit 26 provided in the presentation device 2, the detection unit 26a of the home appliance device 8 owned by the user 5, and the detection unit 26b of the measurement device 9 owned by the user 5. The acquisition unit 19 can also acquire user information from various external systems, etc. This configuration will also be described later.

[0144] As described above, in this specific example, the information presentation system 100 is an information presentation system 100 that presents one of a plurality of meal suggestions to the user 5. Therefore, each of the intermediate words in this specific example is a word associated with attributes related to one or more of the meal suggestions among the plurality of meal suggestions.

[0145] The information presentation system 100 in this specific example operates as follows. Fig. 9 is a flowchart showing the operation of the information presentation system according to the specific example of the embodiment. As shown in Fig. 9, first, the acquisition unit 19 acquires user information related to the user 5 (acquisition step S101). Next, the first determination unit 11 determines condition information related to the user 5 from the acquired user information, and determines a plurality of intermediate words based on the condition information (first determination step S102). The condition information according to this specific example will be described later together with an explanation of the user information.

[0146] Next, the first presentation unit 13 presents a plurality of intermediate words to the user 5 so as to allow the user 5 to select one or more intermediate words from the plurality of intermediate words (first presentation step S103). Next, the second determination unit 12 determines, from the plurality of meal suggestions, meal suggestions that correspond to the one or more intermediate words selected by the user 5 (second determination step S104). Next, the second presentation unit 14 presents the determined meal suggestions to the user 5 (second presentation step 105). This has the advantage that convenience for the user 5 is improved while the intention of the user 5 is more easily reflected in the meal suggestions.

[0147] Furthermore, the intermediate words presented as described above can be deleted at the discretion of the user 5. For example, FIG. 10 is a diagram illustrating the deletion of intermediate words according to a specific example of the embodiment. In FIG. 10, the intermediate words B1 before a deletion request is sent are shown on the left, and the intermediate words B1 after the deletion request is sent are shown on the right. As shown in FIG. 10, the user 5 can request whether or not to delete each of the intermediate words B1 that have been presented. For example, the user 5 presses and taps on the display screen 250 for a long time on the intermediate word B1 that the user 5 wants to delete. This displays a submenu B2 for the intermediate word B1. By selecting "Delete" from this submenu B2, the intermediate word B1 selected by the user 5 is deleted.

[0148] Furthermore, "delete" here includes temporarily notifying the user 5 and permanently notifying the user 5. For example, it may be appropriate to present information such as "Komatsuna expiration date," which has a strong notification meaning to the user 5, when the user 5 eventually buys more komatsuna and the expiration date approaches again. On the other hand, for information that reflects the user 5's behavioral characteristics, such as "time saving," it is preferable to permanently not present the information if the user 5 does not want it to be presented. Therefore, in this specific example, the user 5 is configured to be able to select whether to make the information temporarily not presented or permanently not presented. This selection is made by the user 5 arbitrarily selecting, for example, either "delete" or "permanently delete" (not shown).

[0149] An intermediate word B1 selected for permanent deletion is managed, for example, as shown in Fig. 11. Fig. 11 is a diagram showing an example of a hide list according to a specific example of the embodiment. As shown in Fig. 11, an intermediate word B1 selected for permanent deletion is registered in the hide list. Such a hide list is stored in the storage unit 17 or the like, and is updated every time the user 5 permanently deletes an intermediate word B1.

[0150] When deleting this intermediate word B1, the information presentation system 100 operates as follows. Fig. 12 is a flowchart showing the operation related to the deletion of an intermediate word according to a specific example of the embodiment. As shown in Fig. 12, the processing unit P1 first accepts input of a deletion request from the user 5 via the input unit 24 of the presentation device 2 or the like (first reception step S201). Upon accepting the deletion request, the processing unit P1 changes the image to be presented by the presentation device 2, and deletes the presentation of the intermediate word B1 to be deleted from the multiple presented intermediate words B1 (step S202). Furthermore, the processing unit P1 determines whether this deletion request is for temporary deletion or permanent deletion (not shown), and if it is for permanent deletion, registers the intermediate word B1 to be deleted in the non-display list (registration step S203).

[0151] Thereafter, in a first determination step S102, the first determination unit 11 determines, based on the condition information, to present a plurality of intermediate words excluding the intermediate word to be deleted that is registered in the hide-off list. As a result, the intermediate word B1 registered in the hide-off list will no longer be displayed in the subsequent processing. Note that, the intermediate word B1 may be deregistered from the hide-off list based on a separate operation by the user 5, so that the intermediate word B1 can be presented again.

[0152] Furthermore, the intermediate word B1 presented as described above can be updated at the discretion of the user 5. For example, FIG. 13 is a diagram illustrating an example of updating an intermediate word according to a specific example of an embodiment. In FIG. 13, the intermediate word B1 before an update request is sent is shown on the left, and the intermediate word B1 after the update request is sent is shown on the right. As shown in FIG. 13, once an intermediate word B1 has been presented, if the user 5 determines that there is no intermediate word B1 that suits him, the user 5 can request that the displayed intermediate word B1 be updated. For example, the user 5 long-presses and taps anywhere on the display screen 250 where the intermediate word B1 is presented. This displays a submenu B2. By selecting "Update Display" from this submenu B2, a new intermediate word B1 is presented in place of the presented intermediate word B1.

[0153] In updating the intermediate words B1, the information presentation system 100 operates as follows. FIG. 14 is a flowchart showing the operation of updating intermediate words according to the specific example of the embodiment. As shown in FIG. 14, the processing unit P1 first accepts an input of an update request from the user 5 via the input unit 24 of the presentation device 2 or the like (second reception step S301). Upon accepting the deletion request, a third determination unit (not shown) included in the processing unit P1 determines updated intermediate words, which are multiple updated intermediate words B1 different from the multiple intermediate words presented in the first presentation step S102, based on the condition information (third determination step S302). Furthermore, the third presentation unit (not shown) included in the processing unit P1 presents multiple updated intermediate words to the user 5 so that the user 5 can select one or more updated intermediate words (third presentation step S303).

[0154] The third determination unit may be realized by the first determination unit 11. In this case, the first determination unit 11 is an example of a third determination unit. The third presentation unit may be realized by the first presentation unit 13. In this case, the first presentation unit 13 is an example of a third presentation unit. When determining intermediate words B1, the first determination unit 11, for example, determines more intermediate words B1 than the number to be presented, and presents some of the top intermediate words B1 according to a predetermined criterion. Thereafter, when an update request is received, the first determination unit 11 may newly present an intermediate word B1 that is next in rank among the multiple intermediate words B1 determined by the first determination unit 11. This makes it possible to seamlessly present updated intermediate words without undergoing a process of determining a new intermediate word B1.

[0155] Furthermore, the learning unit 18 described in the above embodiment may learn the tendency of intermediate words B1 that do not need to be presented to the user 5, based on the above-mentioned deletion of intermediate words B1 and display update. The learning model generated as a result can be used to determine whether or not an intermediate word candidate tentatively determined by the first determination unit 11 when determining an intermediate word is an intermediate word B1 that should be presented to the user 5.

[0156] Furthermore, in this specific example, among the presented intermediate words B1, an intermediate word B1 that is selected frequently can be presented in a manner that makes it easier to select. Specifically, the acquisition unit 19 further acquires a selection frequency, which is the frequency at which each of a plurality of intermediate words B1 presented in the past was selected, and in the first presentation step S103, presents the plurality of intermediate words B1 in a manner that is based on the selection frequency, for example, the higher the selection frequency, the more emphasized the intermediate word B1 is. The manner of being emphasized may be, for example, a larger tag size as described above, a different color from the other intermediate words B1, or a tag with a different shape from the other intermediate words B1. The manner of being emphasized here may be any manner that can attract the user 5's attention more than the other intermediate words B1.

[0157] Furthermore, in this specific example, information regarding the value of ingredients held by user 5 based on the rarity or price of the ingredients is acquired, and intermediate word B1 is presented in a manner corresponding to the acquired value of the ingredients. To this end, acquisition unit 19 acquires information regarding the value of ingredients held by user 5. For example, acquisition unit 19 may acquire the name and price of an ingredient purchased by user 5 via a website or the like, or may automatically collect information regarding rarity using the name of the ingredient and generate a tag linked to the ingredient name. Furthermore, since the value of an ingredient is largely unique to user 5, information presentation system 100 may have in advance preferences for ingredients of user 5, and the value may be calculated based on these preferences.

[0158] As a result of the above, in the first presentation step S103, a plurality of intermediate words B1 can be presented in a manner corresponding to the value of the ingredients. For example, FIG. 15 is a diagram illustrating intermediate words presented in a manner corresponding to the value of the ingredients according to a specific example of an embodiment. As shown in FIG. 15, an intermediate word B1 such as "bluefin tuna" which is relatively expensive is presented in a manner that it is emphasized compared to intermediate words B1 such as "pacific saury" and "small horse mackerel" which are relatively inexpensive. More specifically, an intermediate word B1 such as "bluefin tuna" which is relatively expensive is presented in a manner that the tag size is larger than that of other intermediate words B1. Note that, again, there are no particular limitations on the manner in which the intermediate word B1 is presented, as long as the higher the value of the ingredient, the more emphasized the intermediate word B1 is presented.

[0159] Furthermore, in combination with the presentation of intermediate words related to the expiration date of ingredients, as explained above in the example of the intermediate word B1 for "komatsuna expiration date," the approaching expiration date of bluefin tuna, which is more expensive than saury and small horse mackerel, may be presented with greater emphasis when the expiration date approaches. For example, if there is one day left until the expiration dates of saury and small horse mackerel, and two days left until the expiration date of bluefin tuna, the bluefin tuna may be presented with even more emphasis. In this way, the value of ingredients may be used to adjust the threshold for the period when presenting intermediate words related to the expiration date of ingredients. Furthermore, for ingredients with the same remaining time until their expiration date, the intermediate word B1 may be presented simply in a manner emphasizing the value of the ingredient. For example, when there is one day left until the expiration dates of saury and bluefin tuna, the bluefin tuna may be presented with a larger tag and emphasized, as shown in the figure.

[0160] (4.2) Relationship between user information and condition information The relationship between the user information and the condition information in this specific example will be described below. For example, in this specific example, intermediate words B1 based on the acquired user information are presented as shown in FIG. 16. FIG. 16 is a diagram illustrating intermediate words presented based on the user information according to a specific example of the embodiment. As shown in FIG. 16, the intermediate words B1 presented in this specific example may include words that improve the health of the user 5 ("I'm worried about my weight" in the figure), words that are in line with behavior estimated from the behavioral characteristics of the user 5 ("Trending on SNS" in the figure), words related to meals that can be prepared within the cooking time available to the user 5 ("Takeout" in the figure), and words that promote the improvement of the cooking ability of the user 5 ("Try a new cooking method" in the figure). Each of these words will be described in detail below.

[0161] (4.2.1) Condition information from the perspective of health First, user information related to improving the health of the user 5 will be described. Here, the user information is acquired from an external schedule management system, a measurement device 9, a home appliance 8, and the like. The user information includes, for example, a schedule related to the date and time when the user 5 will exercise. The user information also includes vital sign information of the user 5 acquired from stationary, portable, or implantable devices such as a blood pressure monitor, a blood glucose meter, a toilet seat with a warm water washing function, a weighing scale, an activity monitor, and a thermometer, which are examples of the measurement device 9. The user information also includes information related to the time difference between going to bed and waking up, or sleep deprivation based on sleep quality, which is acquired from devices such as bedding, lighting devices, and air conditioners, which are examples of the home appliance 8. The user information also includes information related to the date and time, location information, and the like acquired from devices such as a clock device, which is an example of the presentation device 2 or the home appliance 8.

[0162] The user information also includes test results such as test values obtained at a medical institution or diagnosis results such as the name of a diagnosed disease. This can be achieved by the user 5 capturing an image of a form containing the diagnosis results using a camera or the like, or by acquiring the information via a network in cooperation with a server at the medical institution. The user information may also be acquired from a fitness-related application, such as running or exercise, by linking with the application. Information acquired from the application includes running or exercise history, physical information, heart rate, blood pressure, and basic health functions such as activity level. If the application stores user information in a storage server or the like on a network, the user information may be acquired from the storage server or the like via the application. The user information also includes information about date and time and location information acquired from a device such as a clock device, which is an example of the presentation device 2 or the home appliance 8.

[0163] For example, the condition information determined from the user information may include a nutritional intake goal set according to the health level of user 5 and information about the exercise being performed. Then, intermediate words are determined according to the set nutritional intake. For example, if user 5 exercises a lot, the condition information is estimated to indicate that user 5 wants to increase muscle strength, so an intermediate word B1 such as "efficient muscle strength increase" is presented, and a meal suggestion with a relatively high protein content is made. Furthermore, for example, if user 5 exercises a little, the condition information is estimated to indicate that user 5 wants to suppress weight gain, so an intermediate word B1 such as "I'm concerned about my weight" is presented, and a low-calorie meal suggestion is made. Note that even if a meal is eaten late at night, an intermediate word B1 such as "I'm concerned about my weight" is similarly presented, and a low-calorie meal suggestion is made.

[0164] Furthermore, for example, if it is detected from the state of the excrement of the user 5 that the intestinal environment is disturbed, it is estimated as condition information that the user 5 is aiming to normalize the intestinal environment, so an intermediate word B1 such as "regulate the stomach" is presented, and a dietary suggestion with adjusted prebiotics and probiotics is made. Furthermore, for example, if a state such as menstruation or pregnancy is detected from the state of the excrement of the user 5, it is estimated as condition information that the user 5 desires dietary support during the menstrual or pregnancy period, so an intermediate word B1 such as "support for menstruation or pregnancy" is presented, and a dietary suggestion is made that can supplement micronutrients that tend to be deficient, such as iron or folic acid.

[0165] Furthermore, for example, if a condition such as abnormal urinary glucose is detected from the state of the user 5's excrement, it is estimated as condition information that the user 5 wishes to improve their diabetes or the like, and therefore an intermediate word B1 such as "I'm concerned about my blood sugar level" is presented, and a dietary suggestion to moderate the rise in blood sugar level is made. In addition to this dietary suggestion, ideas for eating to moderate the rise in blood sugar level may also be presented. Furthermore, for example, if a condition such as high blood pressure is detected from the state of the user 5's blood pressure, it is estimated as condition information that the user 5 wishes to improve their high blood pressure, and therefore an intermediate word B1 such as "I'm concerned about my blood pressure" is presented, and a dietary suggestion to reduce salt intake is made.

[0166] Furthermore, for example, if a state such as high fatigue is detected based on the state of user 5, such as the amount of activity, it is estimated that user 5 wishes to recover from fatigue as condition information, and therefore intermediate words B1 such as "recover from fatigue in preparation for tomorrow" are presented, and meal suggestions with a balanced vitamin content are made.

[0167] Furthermore, for example, the condition information determined from the above user information may be set to reduce the cooking load and provide a soothing effect through meals, depending on information such as the stress level and lack of sleep of the user 5. Then, intermediate words are determined according to the set cooking load and soothing effect. For example, if a state such as excessive activity and lack of sleep of the user 5 is detected, it is estimated that the user 5 desires to reduce the cooking load and provide a soothing effect through meals, so intermediate words B1 such as "take a good rest and refresh yourself" are presented, and meal suggestions that require little cooking effort or use a delivery service and that are expected to have a relaxing effect are made.

[0168] Thus, in this specific example, the user information is information relating to the health level of the user 5, and the condition information may include information relating to conditions for improving the health level of the user 5.

[0169] (4.2.2) Condition information in terms of behavioral characteristics Next, user information related to behavior estimated from the behavioral characteristics of the user 5 will be described. Here, the user information is acquired from a web server, a home appliance device 8, an external schedule management system, a sensor device, and the like. The user information includes, for example, information that the user 5 has come into contact with via a website or the like and that the user 5 has a positive feeling about (for example, information that the user has favorited or posted positive comments about on a social networking service (SNS)). The user information also includes, for example, information that the user has come into contact with through an information appliance such as a television (based on information such as channel information and program information). For example, the condition information determined from the above user information may include a genre of related meal suggestions depending on the object of interest to the user 5. For example, if a specific region is detected as the object of interest to the user 5, it is estimated that the user 5 desires a dining experience related to the specific region, and therefore, an intermediate word B1 such as "local cuisine" is presented as the condition information, and meal suggestions such as traditional cuisine of the specific region are made. Furthermore, for example, if a specific dish is detected as an object of interest to user 5, it is estimated that user 5 desires a dining experience similar to the specific dish as condition information, and therefore an intermediate word B1 such as "Cuisine genre: A" is presented, and meal suggestions are made, such as dishes in the genre to which the specific dish belongs.

[0170] On the other hand, for example, the condition information determined from the above user information is set to avoid genres of meal suggestions related to an object that User 5 is interested in, if User 5 has already experienced that object or if a sufficient period of time has not passed since the previous experience.

[0171] Furthermore, the user information includes, for example, a schedule of events or other events where the user 5 may have an extraordinary experience. In such a case, the condition information determined from the user information includes, for example, a genre of related meal suggestions depending on the event the user 5 will be participating in. For example, if Hinamatsuri (Girl's Festival) or Doyo no Ushi no Hi (Day of the Ox) is detected as an event in which the user 5 will be participating, it is estimated that the user 5 desires a meal experience related to the event, and therefore, an intermediate word B1 such as "Hinamatsuri cuisine" is presented, and meal suggestions such as cuisine related to the event are made.

[0172] The user information also includes, for example, weather information such as the temperature difference between day and night on that day, which allows the user 5 to narrow down meal candidates. For example, if a temperature difference of 5 degrees or more is detected, it is estimated that the user 5 desires a hot or cold meal experience as condition information, and therefore an intermediate word B1 such as "warm food" is presented, and meal suggestions such as hot food are made.

[0173] The user information also includes, for example, information about the time and location at which available ingredients are determined. For example, when the current time and the location of user 5 are detected, it is estimated that the user 5 desires a meal using ingredients that are available at a store that is within the user's current location and that are as cheap as possible. Therefore, an intermediate word B1 such as "I'm going to buy ingredients now" is presented, and meal suggestions such as dishes that can be prepared with the available ingredients are made as described above. At this time, information about stores to visit may also be presented.

[0174] Alternatively, the user information may simply include a schedule such as anniversaries. For example, if a schedule such as an anniversary is detected, it is estimated that the user 5 desires a dining experience related to the anniversary, and therefore intermediate words B1 such as "wedding anniversary" are presented as condition information, and meal suggestions are made that are estimated from the dishes eaten on past wedding anniversaries.

[0175] Furthermore, information such as the acquisition of favorite ingredients may be acquired as user information. For example, when favorite ingredients have been learned and the acquisition of the favorite ingredients is detected, it is estimated that the user 5 desires a meal using the favorite ingredients as condition information, so an intermediate word B1 such as "dishes using lamb" may be presented, and meal suggestions using lamb may be made. Furthermore, when favorite ingredients have been learned and it is detected that the user 5 has not eaten a meal using the favorite ingredients for some time, it is estimated that the user 5 desires a meal using the favorite ingredients as condition information, so an intermediate word B1 such as "dishes using lamb" may be presented, and meal suggestions using lamb may be made.

[0176] Furthermore, for example, in cases where multiple eaters are expected, such as a family of multiple people, it may be estimated which of the eaters the condition information will be set around based on past trends in meal suggestion selection, etc. For example, for a user 5 who selects a relatively large number of meal suggestions flagged for children, the user information to be acquired may be acquired from a family member who is a child in the family of the user 5. On the other hand, for a user 5 who selects a relatively large number of meal suggestions flagged for adults, the user information to be acquired may be acquired from a family member who is an adult in the family of the user 5.

[0177] The user information also includes, for example, information regarding the cooking cycle of user 5. For example, if it is determined that user 5 tends to spend a relatively large amount of time cooking on the first and third days out of seven consecutive days, it is estimated that user 5 wishes to do all the cooking on the first and third days as condition information, and therefore intermediate words B1 such as "prepare" are presented on the first and third days, and meal suggestions such as dishes that can be prepared in advance are made. On the other hand, intermediate words B1 such as "save time" are presented on the second day and the fourth to seventh days, and meal suggestions centered on consuming dishes that have been prepared in advance are made.

[0178] The user information also includes, for example, information about the cooking habits of the user 5. For example, when information about cooking habits such as cooking utensil usage tendencies, such as using the microwave or grilling frequently, cooking a lot of fried foods, or cooking a lot of one-plate meals, has been learned, and when it is detected that ingredients that fit these tendencies have been obtained, an intermediate word B1 such as "the usual" is presented, and meal suggestions such as dishes that fit the cooking habits are made.

[0179] In this specific example, the user information is information relating to the behavioral characteristics of the user 5, and the condition information may include information relating to conditions that are in line with the behavior estimated from the behavioral characteristics of the user 5.

[0180] (4.2.3) Condition information in terms of cooking time Next, user information related to meals that can be prepared within the cooking time available to the user 5 will be described. Here, the user information is acquired from an external schedule management system, a home appliance 8, a sensor device, etc. The user information includes, for example, a schedule related to times when the user 5 is unavailable to cook. The user information also includes information such as operation status acquired from devices such as a washing machine, a vacuum cleaner, and a dishwasher, which are examples of home appliances 8. The user information also includes information related to the activity status of the user 5 acquired from devices such as a camera, a microphone, and a thermal image sensor, which are examples of sensor devices, and information related to the remaining amount of housework, which is the amount of housework that has not yet been done. The user information may also include information related to the busyness of the user 5, which is determined by machine learning or the like from the number of times a dedicated app has been launched and the timing of taps on push notifications, etc., acquired from the presentation device 2.

[0181] For example, the condition information determined from the above user information may be set to a cooking time that can be prepared within the cooking time available based on the time when the user 5 is unavailable for cooking, the operating status, the activity status, and the remaining amount of housework. An intermediate word is then determined according to this set cooking time. For example, if there is a dish that can be cooked within the cooking time available to the user 5, and the user 5 has ingredients that can be used to cook that dish, it is estimated that the user 5 wishes to cook that dish using those ingredients, and therefore an intermediate word B1 such as "cookable in the remaining time" is presented, and a meal suggestion to cook the above dish is made.

[0182] Also, for example, if there is no dish that can be cooked within the cooking time available to user 5, it is assumed that user 5 does not wish to cook a dish as condition information, and therefore intermediate words B1 such as "eating out" or "take-out" are presented, and nearby restaurants that offer eating out or take-out meals are presented based on user 5's location information, etc.

[0183] Furthermore, the meal suggestions presented in the above process may be suggestions in which the sum of cooking time, eating time, and cleanup time falls within the above-mentioned cooking time. For example, meal suggestions may be made that meet children's preferences so that they do not require a long time to eat, or meal suggestions such as one-bowl dishes that require few dishes may be made. Furthermore, if the eating time is below a predetermined threshold, meal suggestions may be made for relatively easy-to-digest dishes.

[0184] On the other hand, if a relatively large amount of cooking time is available, intermediate words B1 such as "food education" or "prepared meals" may be presented, and suggestions for making effective use of the cooking time of the user 5 may be made. At this time, tips on how to help with food education may also be presented.

[0185] Thus, in this specific example, the user information is information regarding the cooking time available for user 5 to cook a meal, and the condition information may include information regarding the conditions under which a meal can be prepared within user 5's cooking time.

[0186] (4.2.4) Condition information in terms of cooking ability Next, a description will be given of user information related to what promotes improvement of the cooking ability of user 5. Here, the user information is acquired from storage unit 17 or the like. The user information includes, for example, cooking history information related to the history of cooking performed by user 5 in the past.

[0187] For example, the condition information determined from the above user information may be set to indicate that user 5 is promoting the improvement of his or her cooking ability. Then, an intermediate word is determined according to this set improvement in cooking ability. For example, if it is detected from user 5's cooking history that he or she has performed a certain level of cooking a predetermined number of times, it is estimated that user 5 desires to be presented with dishes that involve cooking at a level higher than the certain level as condition information, and therefore an intermediate word B1 such as "improve your cooking level" is presented, and meal suggestions for cooking the above dishes are made. Furthermore, for example, if it is detected from user 5's cooking history that he or she has performed a certain level of cooking a predetermined number of times, it is estimated that user 5 desires to be rewarded for cooking, and therefore an intermediate word B1 such as "reward for hard work" is presented, and meal suggestions are made, such as issuing coupons and dining out to which coupons can be applied.

[0188] Thus, in this specific example, the user information is information about the cooking ability of the user 5 when cooking a meal, and the condition information may include information about conditions that promote improvement of the cooking ability of the user 5.

[0189] Note that words corresponding to attributes related to meal suggestions refer to words generally associated with the attributes, or can be rephrased as words related to the attributes. Specifically, for example, while "time-saving" and "deadline" are exemplified as intermediate words B1 corresponding to "cooking time," words generally associated with the length of time, such as "quick," "quick," "relaxed," and "slow," may also be used. In this word selection, general words are selected at the time when user 5 uses information presentation system 100. For this reason, server 1a may periodically read websites with recent updates to accumulate "general" word candidates, or an administrator of server 1a may manage the "general" word candidates by adding and deleting them. Furthermore, words corresponding to attributes may be individually selected for user 5 by learning what words user 5 selects when entering data into other applications, such as a text editor.

[0190] (4.6) Summary of specific implementation examples As described above, the information presentation method in this example is an information presentation method for presenting a meal suggestion to a user 5 from a plurality of meal suggestions, and includes: an acquisition step for acquiring user information related to the user 5; a first determination step for determining condition information related to the user 5 from the acquired user information and determining a plurality of intermediate words B1 based on the condition information; a first presentation step for presenting the plurality of intermediate words B1 to the user 5 so as to allow the user 5 to select one or more intermediate words B1 from the plurality of intermediate words B1; a second determination step for determining, from the plurality of meal suggestions, meal suggestions that correspond to the one or more intermediate words B1 selected by the user 5; and a second presentation step for presenting the determined meal suggestions to the user 5, wherein each of the plurality of intermediate words B1 is a word corresponding to an attribute related to any one or more meal suggestions from the plurality of meal suggestions.

[0191] According to this information presentation method, meal suggestions to the user 5 can be determined by presenting intermediate words B1 based on the user information. The intermediate words B1 are words that are likely to be selected based on the user information and in light of the current situation of the user 5. In this way, meal suggestions that are in line with the situation of the user 5 can be made simply by selecting intermediate words B1 that are in line with the situation that the user 5 is thinking or feeling, thereby improving convenience for the user 5 and enabling meal suggestions that are likely to reflect the intentions of the user 5.

[0192] Furthermore, for example, the user information may be information relating to the health level of the user 5, and the condition information may include information relating to conditions for improving the health level of the user 5.

[0193] According to this, user information relating to the health level of the user 5 is acquired, and the intermediate word B1 can be determined and presented based on the condition that the health level of the user 5 is improved.

[0194] Furthermore, for example, the user information may be information relating to the behavioral characteristics of the user 5, and the condition information may include information relating to conditions that are in line with the behavior of the user 5 estimated from the behavioral characteristics.

[0195] This makes it possible to acquire user information relating to the behavioral characteristics of the user 5, and determine and present the intermediate word B1 based on the condition that it conforms to the behavior estimated from the behavioral characteristics of the user 5.

[0196] Furthermore, for example, the user information may be information regarding the cooking time available for user 5 to cook a meal, and the condition information may include information regarding the conditions under which a meal can be prepared within user 5's cooking time.

[0197] This allows user information regarding the cooking time available for user 5 to cook a meal to be obtained, and intermediate word B1 to be determined and presented based on the condition that the meal can be prepared within user 5's cooking time.

[0198] Furthermore, for example, the user information may be information relating to the cooking ability of the user 5 when cooking a meal, and the condition information may include information relating to conditions that promote the improvement of the user 5's cooking ability.

[0199] This allows user information regarding the cooking ability of the user 5 when cooking a meal to be acquired, and intermediate words B1 to be determined and presented based on the condition of promoting improvement in the cooking ability of the user 5.

[0200] Furthermore, for example, after the first presentation step, the method may further include a first reception step of receiving an update request from the user 5, a third determination step of, when the update request is received, determining, based on condition information, a plurality of update intermediate words different from the plurality of intermediate words B1 presented in the first presentation step, and a third presentation step of presenting the determined plurality of update intermediate words to the user 5 so as to allow the user 5 to select one or more update intermediate words.

[0201] According to this, if the user 5 determines that the presented intermediate words B1 do not contain words that match his / her own thoughts, situation, etc., he / she can request the presentation of updated intermediate words that are different from the presented intermediate words B1. This can enhance the effect of making it easier for the intention of the user 5 to be reflected.

[0202] Furthermore, for example, after the first presenting step, the method may further include a second receiving step of receiving a deletion request in which the user 5 has selected an intermediate word B1 to be deleted from among the plurality of intermediate words B1, and when the deletion request is received, the intermediate word B1 to be deleted may be deleted from the plurality of presented intermediate words B1.

[0203] According to this, if there is a restriction on the number of intermediate words B1 to be presented, for example, a situation may occur in which one of the slots is filled with an intermediate word B1 that is not often selected. In this case, the intermediate word B1 that is not often selected can be deleted, making it possible to make the most of the number of intermediate words B1 to be presented. As a result, the possibility of presenting intermediate words B1 that are in line with the thoughts, situations, etc. of the user 5 is improved, thereby enhancing the effect of more easily reflecting the intentions of the user 5.

[0204] Furthermore, for example, the method may further include a registration step of registering the intermediate word B1 to be deleted in the hidden list when a deletion request is received, and the first determination step may determine a plurality of intermediate words B1 based on the condition information and excluding the intermediate word B1 to be deleted registered in the hidden list.

[0205] This makes it possible to permanently delete the intermediate word B1, thereby preventing the intermediate word B1 from being presented thereafter if the intermediate word B1 does not match the thoughts, situation, etc. of the user 5. As a result, the possibility of presenting an intermediate word B1 that matches the thoughts, situation, etc. of the user 5 increases, thereby enhancing the effect of making it easier for the intention of the user 5 to be reflected.

[0206] Furthermore, for example, information regarding the value of ingredients based on the rarity or price of ingredients held by the user 5 may be acquired, and in the first presentation step, multiple intermediate words B1 may be presented in a manner according to the value of the ingredients.

[0207] This allows the display mode of the intermediate word B1 to be changed based on a general value or a unique value assigned to the user 5. As a result, when a high-value ingredient is nearing its expiration date or when a high-value ingredient has been purchased but left untouched, the user 5 can be effectively reminded of this and can also be led to meal suggestions using this ingredient. Therefore, the user's convenience can be improved while the effect of easily reflecting the user's wishes can be enhanced.

[0208] Furthermore, for example, the selection frequency of each of a plurality of intermediate words B1 that have been presented in the past may be obtained, and in the first presentation step, the plurality of intermediate words B1 may be presented in a manner according to the selection frequency.

[0209] This allows intermediate words B1 that are selected relatively frequently to be handled separately from intermediate words B1 that are selected relatively infrequently or that are not selected at all. For example, it can be assumed that intermediate words B1 that are selected relatively frequently are in line with the thoughts or situations of the user 5, and therefore it becomes possible to present such intermediate words B1 with more emphasis. This improves user convenience while enhancing the effect of making it easier for the user's intentions to be reflected.

[0210] The program in this example is a program for causing a computer to execute the information presentation method described above.

[0211] This makes it possible to achieve the same effect as the above-described information presentation method using a computer.

[0212] Moreover, the information presentation system 100 in this example is an information presentation system that presents a user with one of a plurality of meal suggestions related to meals, and includes an acquisition unit that acquires user information related to the user, a first determination unit that determines condition information related to the user from the acquired user information and determines a plurality of intermediate words based on the condition information, a first presentation unit that presents the plurality of intermediate words to the user so as to allow the user to select one or more intermediate words from the plurality of intermediate words, a second determination unit that determines, from the plurality of meal suggestions, meal suggestions that correspond to one or more intermediate words selected by the user, and a second presentation unit that presents the determined meal suggestions to the user, wherein each of the plurality of intermediate words is a word that corresponds to an attribute related to any one or more of the meal suggestions from the plurality of meal suggestions.

[0213] This makes it possible to realize an information presentation system 100 that can achieve the same effects as the above-described information presentation method.
