Figure 2 S1 to S5 of FIG. 1 represent the operation of the control unit 11 of the control device 10 when the user goes to the event venue. S6 to S11 represent the operation of the control unit 11 when the user returns from the event venue.

[0039] exist Figure 2 In S1 of the control device 10, the control unit 11 detects that the user is on the outbound journey to the event venue. Any method can be used to detect that the user is on the outbound journey. For example, the control unit 11 communicates with the terminal device 20, and receives information indicating that the user has set the destination of any route search application to the event venue and location information indicating the user's location from the terminal device 20. In the case where it is determined that the user has started moving based on the information and the location information, the control unit 11 can detect that the user is on the outbound journey. The control unit 11 can also obtain location information indicating the location of the vehicle 30 measured by the positioning unit 35 from the vehicle 30, and detect that the user is on the outbound journey based on the location information. In this example, the control unit 11 detects that the user is on the outbound journey to the event venue by detecting that the user has taken the vehicle 30 to the event venue of the Hokkaido exhibition. Any method can be used to detect that the user is riding in the vehicle 30. For example, the control unit 11 obtains location information indicating the location of the user measured by the positioning unit 25 from the terminal device 20, and detects that the user is riding in the vehicle 30 based on the location information. The control unit 11 may acquire an image of the interior of the vehicle 30 and analyze the image using any image processing technology to identify the user, thereby detecting that the user is riding in the vehicle 30 .

[0040] In S2, the control unit 11 obtains the interest information representing the object of interest of the user. Any method can be used to obtain the interest information. The control unit 11 can obtain the interest information by reading it from the storage unit 12. Without being limited to this, the control unit 11 can also send information representing an inquiry about the object of interest to the terminal device 20, receive the answer input by the user to the terminal device 20, and associate the received answer with the user's identifier to obtain it as the interest information. In this case, the user's identifier can also be the identifier of the terminal device 20. In this example, the control unit 11 obtains the interest information indicating that the tourist destination "Sapporo" is the object of interest of the user.

[0041] Without being limited to this, the control unit 11 may also obtain the information of interest by generating the information of interest based on the purchase history of the user's goods or services. In this case, the control unit 11 obtains the information indicating the purchase history from the server of the credit card company used by the user, etc. The control unit 11 may generate the information of interest based on the goods or services indicated in the purchase history. Any language analysis technology may be used in the identification of the object of interest. For example, in the case where the information indicating the purchase history indicates a travel guide for Sapporo, the control unit 11 may also obtain the information of interest by generating the information of interest with the user's object of interest set to "Sapporo".

[0042] In S3, the control unit 11 obtains advertising information associated with the activity in the event venue. Any method can be used to obtain this information. For example, the advertising information is pre-set by the company exhibiting at the event venue or the organizer of the activity, and is stored in the storage unit 12. The control unit 11 reads the advertising information by referring to the storage unit 12, thereby obtaining the advertising information. Not limited to this, the control unit 11 can also obtain advertising information from an advertising server of a company exhibiting or planning a booth or entertainment event, or the organizer of the event. The control unit 11 can also obtain multiple advertising information. In this example, the control unit 11 obtains advertising information indicating the Sapporo sightseeing tour guided in the booth and the venue map to the booth for the booth related to "Sapporo" exhibited in the event venue of the Hokkaido exhibition. In addition, the control unit 11 obtains advertising information indicating the Hakodate sightseeing tour guided in the booth and the venue map to the booth for the booth related to "Hakodate".

[0043] In S4, the control unit 11 selects advertising information based on the interest information. The control unit 11 may also select advertising information associated with the user's object of interest from the multiple advertising information obtained in S3. The selection may be performed by any method. The control unit 11 may also use any natural language processing technology to select advertising information associated with the user's object of interest. For example, when the user's object of interest represented by the interest information is dessert, the control unit 11 selects advertising information about a booth of a Japanese candy store, a booth of a Western candy store, or a booth of a candy supply company as advertising information associated with the user's object of interest. In this example, the control unit 11 selects advertising information associated with "Sapporo" as the user's object of interest from the advertising information obtained in S3, indicating a Sapporo sightseeing tour guided in a booth related to "Sapporo" and a venue map to the booth.

[0044] In S5, the control unit 11 notifies the user of the advertisement information. The notification may be performed by any method. For example, the control unit 11 sends the advertisement information to the user's terminal device 20, and the control unit 21 of the terminal device 20 displays the advertisement information to the user via the input / output unit 24. In this example, the control unit 11 sends the advertisement information to the terminal device 20 and displays the advertisement information on the input / output unit 24 of the terminal device 20. The advertisement information indicates a tourist tour of Sapporo and a venue map leading to a booth related to "Sapporo".

[0045] In S6, the control unit 11 detects that the user is on the return trip from the event venue. Any method can be used to detect that the user is on the return trip. For example, the control unit 11 communicates with the terminal device 20, and receives information indicating that the user sets the destination of any route search application to his home and starts moving and location information indicating the user's location from the terminal device 20. In the case where it is determined that the user has started moving based on the information and the location information, the control unit 11 can also detect that the user is on the return trip. In this example, the control unit 11 detects that the user is on the return trip from the event venue by detecting that the user has taken a vehicle 30 departing from the event venue. Any method can be used to detect that the user is riding in the vehicle 30. For example, as in S1, the control unit 11 obtains location information indicating the user's location from the terminal device 20, and detects that the user is riding in the vehicle 30 based on the location information. The control unit 11 can also obtain an image obtained by shooting the interior of the vehicle from the vehicle 30, and analyze the image by any image processing technology to determine the user, thereby detecting that the user is riding in the vehicle 30.

[0046] In S7, the control unit 11 determines the booth visited by the user at the event venue. Any method can be used for determination. For example, the control unit 11 obtains an image of the user's goods, and determines the booth visited by the user based on the goods determined based on the image. In this example, the control unit 11 obtains an image of the user taken by the shooting unit 36 ​​from the vehicle 30, and uses any image analysis technology to determine the goods held by the user based on the image. The control unit 11 determines the booth visited by the user at the event venue based on the determined result. For example, when it is determined that the goods held by the user are products or flyers posted at a certain booth, the control unit 11 determines the booth as the booth visited by the user.

[0047] In this embodiment, the goods determined by the control unit 11 are shopping bags handed to users when selling goods or delivering novelty goods at each booth, and the colors are different for each booth. The control unit 11 determines the color of the shopping bag and determines the color of the shopping bag with the largest number held by the user. The control unit 11 determines the booth visited by the user by referring to the information indicating the association between the color of the shopping bag and the booth. The information is set in advance by the organizer of the event and stored in the storage unit 12. The control unit 11 can also obtain the information from the server of the organizer of the event venue. In this example, the user holds three red bags, one blue bag, and one yellow bag. In the Hokkaido exhibition in this example, red is the color of the bags used in the booth related to Hakodate, blue is the color of the bags used in the booth related to Kushiro, and yellow is the color of the bags used in the booth related to Sapporo. In this case, the control unit 11 determines the booth related to "Hakodate" where the largest number of red bags held by the user are used as the booth visited by the user at the event venue.

[0048] Without limitation, the control unit 11 may also determine the booth visited by the user by obtaining the user's location information from the user's terminal device 20. The control unit 11 may also obtain an image captured by a camera installed in the event venue, and use any image analysis technology to analyze the image to determine the booth visited by the user. In this case, the control unit 11 may determine the booth where the user stayed the longest as the booth visited by the user.

[0049] In S8, the control unit 11 obtains the user's interest information based on the determined booth. Specifically, the control unit 11 obtains the interest information by reading the information stored in the storage unit 12, which pre-establishes the association between the booth and the interest information. The information is pre-set and stored in the storage unit 12. In this example, the interest information indicating "Hakodate" is pre-established in association with the booth visited by the user. In this case, the control unit 11 obtains the interest information indicating "Hakodate" as the user's object of interest.

[0050] Without limitation to this, any method may be used to obtain the information of interest based on the booth visited by the user. For example, the control unit 11 obtains the information by reading out information stored in the storage unit 12, which pre-establishes a correspondence between the booth and the category to which the booth belongs, and information pre-establishes a correspondence between the category and the information of interest. For example, in this information, the booth visited by the user is pre-established to correspond to the category indicating "kitchenware", and the category of "kitchenware" is pre-established to correspond to the information of interest of "dishes". In this case, the control unit 11 obtains the information of interest indicating "dishes" as the object of interest of the user.

[0051] In S9, the control unit 11 obtains advertising information associated with the activity at the activity venue. Any method can be used to obtain this information. For example, the advertising information is pre-set by the company exhibiting at the activity venue or the organizer of the activity, and is stored in the storage unit 12. The control unit 11 reads the advertising information by referring to the storage unit 12, thereby obtaining the advertising information. Without being limited to this, the control unit 11 can also obtain the advertising information from the advertising server of the company exhibiting or planning a booth or entertainment activity, or the organizer of the activity. The control unit 11 can also obtain multiple advertising information.

[0052] In S10, the control unit 11 selects advertising information based on the interest information. Specifically, the control unit 11 selects advertising information representing an advertisement associated with the object of interest represented by the interest information acquired in S8. The selection of advertising information may be performed by any method. In this example, the control unit 11 selects advertising information representing sightseeing in Hakodate as advertising information associated with the object of interest "Hakodate" represented by the interest information.

[0053] The control unit 11 may select advertising information based on the interest information obtained in S2 in addition to the interest information obtained in S8. For example, when the object of interest obtained in S2 is "dessert" and the object of interest obtained in S8 is "Hakodate", the control unit 11 may select advertising information related to the products of a dessert shop in Hakodate. Similarly, when the object of interest obtained in S2 is "seafood dishes" and the object of interest obtained in S8 is "Hakodate", the control unit 11 may select advertising information related to a seafood dish shop in Hakodate or advertising information related to sightseeing tours targeting the market of Hakodate.

[0054] In S11, the control unit 11 notifies the user of the advertisement information. For example, the control unit 11 sends the advertisement information to the user's terminal device 20, and the control unit 21 of the terminal device 20 displays the advertisement information to the user via the input / output unit 24. In this example, the control unit 11 sends the advertisement information indicating sightseeing in Hakodate to the user's terminal device 20, and the advertisement information is displayed on the input / output unit 24 of the terminal device 20. After that, the processing of the control unit 11 ends.

[0055] As described above, the control unit 11 of the control device 10 involved in this embodiment obtains interest information representing the user's object of interest, selects advertising information based on the interest information, and notifies the user of the advertising information during the user's journey to the event venue or the return journey from the event venue. According to this embodiment, advertisements suitable for the user's interests are prompted to the user. Therefore, the possibility of a user who has seen an advertisement on the way to the event venue or the return journey to take actions such as going to the booth indicated by the advertisement after arriving at the event venue or purchasing the goods indicated by the advertisement after returning home from the event venue is increased. Therefore, the technology of prompting advertisements to users visiting the event venue can be improved.

[0056] As described above, in the control device 10 according to the present embodiment, the control unit 11 selects the advertisement information associated with the user's object of interest from the plurality of advertisement information associated with the event at the event venue. According to the present embodiment, since the advertisement information associated with the event venue and matching the user's object of interest is selected, the effect of the advertisement for the user visiting the event venue can be increased. Therefore, the technology of presenting advertisements to the user visiting the event venue can be improved.

[0057] As described above, in the control device 10 according to the present embodiment, the control unit 11 determines the booth visited by the user at the event venue, and obtains the interest information based on the booth. According to the present embodiment, since the user can be provided with advertising information reflecting the experience at the event venue within a short period of time after the user visits the event venue, the effect of the advertisement to the user can be increased. Therefore, the technology of presenting advertisements to users visiting the event venue can be improved.

[0058] As described above, in the control device 10 according to the present embodiment, the control unit 11 obtains an image of the user's goods, and determines a booth based on the goods held by the user determined from the image. According to the present embodiment, the control unit 11 can accurately determine the booth that the user is interested in and visits at the event venue based on the goods held by the user, and can obtain interest information based on the booth and output advertising information. Therefore, the technology of presenting advertisements to users visiting the event venue can be improved.

[0059] As described above, in this embodiment, the goods include shopping bags. The control unit 11 determines the booth according to the color of the shopping bags. According to this embodiment, even when the user has multiple bags, it is possible to determine the booth that the user is most interested in visiting by distinguishing based on the color. Therefore, the technology of presenting advertisements to users visiting the event venue can be improved.

[0060] The present disclosure is not limited to the above-mentioned embodiments. For example, two or more blocks recorded in the block diagram may be combined, or one block may be divided. Instead of executing two or more steps recorded in the flowchart in chronological order according to the description, the steps may be executed in parallel or in a different order according to the processing capability of the device executing each step or as required. In addition, changes can be made within the scope of the subject matter of the present disclosure.

[0061] For example, in S5 and S11, the control unit 11 may transmit the advertisement information to the vehicle 30 in which the user is riding. In this case, the control unit 31 of the vehicle 30 receives the advertisement information and causes the input / output unit 34 to display the advertisement information. Thus, the user riding in the vehicle 30 is notified of the advertisement information.

[0062] For example, in S7, the control unit 11 may also determine the booth visited by the user based on the image captured by the user using the terminal device 20. Specifically, the control unit 11 obtains the image captured by the user using the terminal device 20 by receiving it from the terminal device 20, and uses any image analysis technology to determine the goods held by the user. The control unit 11 determines the booth visited by the user at the event venue based on the determined result. For example, when a product or flyer posted at a booth is determined as a good based on the image received from the terminal device 20, the control unit 11 determines the booth as the booth visited by the user.

[0063] For example, in S7, the control unit 11 may also determine the booths visited by multiple users riding in the vehicle 30 at the event site. Specifically, the control unit 11 obtains the image captured by the camera unit 36 ​​of the vehicle 30, and based on the image, uses any image analysis technology to determine the color of the shopping bags held by the multiple users the most, and determines the booth using the shopping bags of the color.
