Embodiments of the present disclosure are described below with reference to the drawings.

First Embodiment
An overview of the information providing device of the present disclosure will be described.

Figure 1 is a block diagram showing an example of the functional configuration of the information providing device 100. As shown in Figure 1, the information providing device 100 comprises a target information acquisition unit 110, a determination unit 120, and an output control unit 130.

The destination information acquisition unit 110 acquires destination information. The destination information indicates the passenger's purpose for using the airport. In this disclosure, airport users are referred to as passengers. The destination information acquisition unit 110 may acquire destination information by receiving input of destination information from the passenger. The destination information acquisition unit 110 may also acquire destination information estimated based on a captured image of the passenger. In this case, the destination information is estimated based on, for example, the passenger's clothing, possessions, and group composition included in the captured image.

In this way, the destination information acquisition unit 110 acquires destination information indicating the passenger's purpose for using the airport. The destination information acquisition unit 110 is an example of a destination information acquisition means.

The determination unit 120 determines the recommended information according to the objective information. The recommended information is information that recommends the use of facilities at the airport. In this case, the determination unit 120 may determine the recommended information using the correspondence information. The correspondence information is information in which the objective information and the recommended information are associated with each other. The determination unit 120 may, for example, determine the recommended information by identifying the recommended information that corresponds to the acquired objective information from the correspondence information. Note that the correspondence information is stored, for example, in a storage device (not shown) included in the information providing device 100 or in an external device that can communicate with the information providing device 100.

In this way, the determination unit 120 determines recommended information, which is information that recommends the use of facilities at the airport, based on the purpose information. The determination unit 120 is an example of a determination means.

The output control unit 130 outputs the recommended information determined by the determination unit 120. For example, suppose the destination information acquisition unit 110 acquires destination information by accepting input of the destination information by the passenger from a terminal owned by the passenger. At this time, the output control unit 130 may control the recommended information to be output on the terminal owned by the passenger. Also, for example, suppose the destination information acquisition unit 110 acquires estimated destination information based on an image captured of the passenger. At this time, the output control unit 130 may control the recommended information to be output on a display device installed within a predetermined range from the image capture device that captured the image. In other words, the output control unit 130 may output the recommended information on a display device installed near the passenger. Furthermore, without being limited to this example, the output control unit 130 may also control a printing device installed within a predetermined range from the image capture device that captured the image to issue a form including the recommended information. In this way, the output control unit 130 may output the recommended information to an output device that the passenger can check.

The output control unit 130 outputs the determined recommended information to the passenger. The output control unit 130 is an example of an output control means.

Next, an example of the operation of the information providing device 100 will be described using Figure 2. Note that in this disclosure, each step in the flowchart will be represented by a number assigned to each step, such as "S1."

Figure 2 is a flowchart illustrating an example of the operation of the information providing device 100. The destination information acquisition unit 110 acquires destination information indicating the passenger's purpose for using the airport (S1). The determination unit 120 determines recommended information, which is information recommending the use of facilities at the airport, based on the destination information (S2). The output control unit 130 outputs the determined recommended information to the passenger (S3).

In this way, the information providing device 100 of the first embodiment acquires purpose information indicating the passenger's purpose for using the airport, and determines recommended information, which is information that recommends the use of facilities at the airport, based on the purpose information. The information providing device 100 then outputs the determined recommended information to the passenger. This allows the information providing device 100 to encourage passengers to use facilities that correspond to their purpose for using the airport. In other words, the information providing device 100 can support the promotion of use of facilities at the airport.

Second Embodiment
Next, an information providing device according to a second embodiment will be described. In the second embodiment, the information providing device 100 described in the first embodiment will be described in more detail. Note that some of the content overlapping with the content described in the first embodiment will not be described again.

Figure 3 is a diagram showing a schematic example of the configuration of an information provision system 1000. As shown in Figure 3, the information provision system 1000 includes an information provision device 100. The information provision device 100 is capable of communicating with at least one of a communication terminal 201, a signage terminal 202, and a printing device 203 via a wireless or wired network.

The communication terminal 201 is an example of a terminal owned by a passenger. The communication terminal 201 is, for example, a smartphone, a tablet terminal, a mobile phone, a personal computer, etc. In other words, the communication terminal 201 is equipped with a display device such as a display, and a speaker.

The signage terminal 202 is an example of a display device installed near passengers. One or more signage terminals 202 are installed at an airport. The signage terminal 202 includes a flat display, a curved display, a display that displays three-dimensional images, and a projector. The signage terminal 202 may also be equipped with a speaker. In other words, the signage terminal 202 may have the function of displaying information and the function of outputting information audibly.

The printing device 203 is an example of a device that issues paper. The printing device 203 may be a device used in a POS (Point of Sales) system. For example, the printing device 203 is a device that issues receipts. The printing device 203 may also be a device used in a system that performs boarding check-in. For example, the printing device 203 may be a device that issues boarding passes. One or more printing devices 203 are installed at an airport.

In this disclosure, when there is no need to distinguish between the communication terminal 201, the signage terminal 202, and the printing device 203, the communication terminal 201, the signage terminal 202, and the printing device 203 are simply referred to as the output device 200. The information provision system 1000 may include the output device 200.

The information providing device 100 may also be capable of communicating with the image capturing devices 300-1, 300-2, ..., 300-n (n is a natural number) via a wireless or wired network. In the present disclosure, when the image capturing devices 300-1, 300-2, ..., 300-n are not distinguished from one another, they are collectively referred to as image capturing devices 300. One or more image capturing devices 300 are installed at an airport. For example, the image capturing device 300 is installed together with the signage terminal 202 and the printing device 203. However, this is not a limitation, and one or more image capturing devices 300 may be installed within a predetermined range from each of the signage terminal 202 and the printing device 203. The image capturing device 300 may also be an integrated device with each of the signage terminal 202 and the printing device 203. The information providing system 1000 may include the image capturing device 300.

[Details of the information provision system 1000]
Fig. 4 is a block diagram showing an example of the functional configuration of the information providing system 1000. As shown in Fig. 4, the information providing device 100 is connected to an output device 200 and an image capturing device 300 so as to be able to communicate with each other.

The output device 200 includes an output unit 210. The output unit 210 acquires recommended information from the information providing device. The output unit 210 then outputs the recommended information. For example, if the output device 200 has a display device such as a monitor, the output unit 210 displays the recommended information on the display device. Also, for example, if the output device 200 has a speaker, the output unit 210 outputs the recommended information by voice. Also, for example, if the output device 200 has a function to issue paper, the output unit 210 prints and issues the recommended information on paper.

The imaging device 300 includes an imaging unit 310. The imaging unit 310 takes images and generates captured images. The imaging unit 310 then transmits the captured images to the information providing device 100. The imaging unit 310 may periodically transmit the captured images to the information providing device 100, or may continuously transmit the captured images to the information providing device 100. The imaging unit 310 may also transmit imaging device identification information that identifies the imaging device 300 to the information providing device 100 in addition to the captured images. The imaging device identification information is information that can identify each imaging device 300. The imaging device identification information may be a code assigned to each imaging device 300, or may be information that indicates the location where the imaging device 300 is installed.

The information providing device 100 comprises a target information acquisition unit 110, a determination unit 120, and an output control unit 130.

The destination information acquisition unit 110 acquires destination information. The destination information indicates the passenger's purpose for using the airport. For example, the destination information may include passengers using the airport for tourism, passengers using the airport for business, and passengers using the airport for studying abroad. Hereinafter, when the destination information indicates that "passengers will use the airport for tourism," it will be expressed as "destination information is tourism." When the destination information indicates that "passengers will use the airport for business," it will be expressed as "destination information is business." When the destination information indicates that "passengers will use the airport for studying abroad," it will be expressed as "destination information is studying abroad." Note that the purpose for using the airport indicated in the destination information is not limited to this example.

For example, the passenger inputs destination information into the destination information acquisition unit 110 by operating the communication terminal 201. The destination information acquisition unit 110 may acquire the input destination information. At this time, the destination information acquisition unit 110 may associate the destination information with passenger identification information that identifies the passenger, and store the information in a storage device (not shown) included in the information provision device 100 or in an external device that can communicate with the information provision device 100.

The destination information acquisition unit 110 may also acquire captured images from the imaging device 300. If a passenger is captured in the captured image, the destination information acquisition unit 110 may estimate the passenger's destination information from the captured image. For example, if the passenger is wearing a suit, the destination information acquisition unit 110 may estimate that the passenger's destination information is business. For example, if the passenger group is made up of families, the destination information acquisition unit 110 may estimate that the passenger's destination information is sightseeing. In this way, the destination information acquisition unit 110 may acquire destination information by estimating the passenger's destination information from the captured image.

The determination unit 120 determines recommended information based on the purpose information. The recommended information is information that recommends the use of facilities at the airport. The recommended information is, for example, information introducing shops, restaurants, lounges, and other service facilities within the airport. In other words, the recommended information may be a guide to using facilities at the airport. The recommended information may also be advertisements for products and services available at facilities at the airport. The recommended information may also be coupons that can be used at facilities at the airport.

The determination unit 120 determines the recommended information, for example, using the corresponding information. Figure 5 is a diagram showing an example of the corresponding information. As shown in Figure 5, the recommended information includes information in which purpose information and recommended information are associated with each other. For example, for an item with purpose information of "business," "lounge usage guide" and "advertisement for product A" are associated as recommended information. In this way, multiple pieces of recommended information may be associated with one piece of purpose information.

The determination unit 120 may, for example, make a determination by selecting recommended information corresponding to the acquired purpose information based on the corresponding information. In the example of FIG. 5, if the acquired purpose information is studying abroad, the determination unit 120 selects an advertisement for Product C as the recommended information. That is, the determination unit 120 determines that the recommended information to be output to the passenger is the advertisement for Product C. Also, in the example of FIG. 5, if the acquired purpose information is business, the determination unit 120 may select either a lounge access guide or an advertisement for Product A, or may select both, as the recommended information to be output to the passenger. When selecting either a lounge access guide or an advertisement for Product A, the determination unit 120 may make a random selection. Alternatively, the determination unit 120 may make a selection using other information. For example, if a passenger is carrying a lot of luggage, the passenger is unlikely to purchase a new product. Therefore, the determination unit 120 may select a lounge access guide. In this way, the determination unit 120 may determine recommended information according to passenger attributes, including the amount of luggage the passenger is carrying. The amount of luggage the passenger is carrying can be estimated, for example, from a captured image.

Furthermore, without being limited to this example, when multiple pieces of recommended information are associated with the acquired objective information, the determination unit 120 may determine the recommended information based on the time of day. For example, when the time is between 11:00 and 13:00, the determination unit 120 may select recommended information related to restaurants, such as restaurant advertisements or restaurant coupons.

Note that the method for determining recommended information is not limited to rule-based methods. For example, the determination unit 120 may use machine learning to determine recommended information. For example, assume that there is a learning model that has learned the relationship between destination information, other information including time and passenger attributes, and passenger behavior. The determination unit 120 uses the learning model to predict passenger behavior from the destination information and other information. The determination unit 120 may then determine recommended information based on the predicted passenger behavior. For example, if it is predicted that the passenger will head to a restaurant, the determination unit 120 may determine recommended information related to the restaurant.

The output control unit 130 outputs the determined recommended information to the passenger. Specifically, the output control unit 130 identifies the output device 200 that is to output the recommended information. The output control unit 130 then transmits the recommended information to the identified output device 200, causing the output device 200 to output the recommended information. At this time, the output control unit 130 may control the output unit 210. That is, the output control unit 130 may output the recommended information on the output device 200. If multiple pieces of recommended information are determined, the output control unit 130 may output the multiple pieces of recommended information in sequence.

For example, when a passenger inputs target information by operating the communication terminal 201, the output control unit 130 identifies the passenger's communication terminal 201 as the device that will output recommended information. Then, the output control unit 130 causes the communication terminal 201 to output the recommended information. At this time, the output control unit 130 may cause the signage terminal 202 to output the recommended information. In this case, the output control unit 130 identifies a signage terminal 202 installed within a predetermined range from the communication terminal 201 based on the location information of the communication terminal 201. Then, the output control unit 130 may cause the identified signage terminal 202 to output the recommended information. The location information of the communication terminal 201 may be periodically transmitted from the communication terminal 201 to the information providing device 100. Furthermore, information on the installation location of the signage terminal 202 is stored in advance in a storage device (not shown) that the information providing device 100 has.

Also, for example, suppose the destination information acquisition unit 110 acquires the destination information by estimating the passenger's destination information from the captured image. At this time, the output control unit 130 causes the signage terminal 202 to output the recommended information. For example, the output control unit 130 identifies the signage terminal 202 installed together with the imaging device 300 that captured the captured image. Then, the output control unit 130 outputs the recommended information to the identified signage terminal 202. Furthermore, the output control unit 130 may cause the printing device 203 to output the recommended information. In this case, the output control unit 130 identifies the printing device 203 installed together with the imaging device 300 that captured the captured image. Note that when the printing device 203 issues paper such as a receipt or boarding pass, it may also issue paper on which the recommended information is printed along with the paper.

Figure 6 shows an example of recommended information. In the example of Figure 6, an advertisement for product A is shown. In this way, the output control unit 130 may output an advertisement recommending a specific product as a souvenir to passengers traveling for business purposes, for example.

[Example of operation of information providing device 100]
Next, an example of the operation of the information providing device 100 will be described with reference to FIG.

Figure 7 is a flowchart illustrating an example of the operation of the information providing device 100. The destination information acquisition unit 110 acquires destination information (S101). The determination unit 120 determines recommended information based on the acquired destination information (S102). For example, the determination unit 120 determines recommended information to be output to the passenger by selecting recommended information that corresponds to the acquired destination information based on the correspondence information.

The output control unit 130 identifies the output device 200 to which the recommended information should be output (S103). Then, the output control unit 130 causes the identified output device 200 to output the recommended information (S104).

In this way, the information providing device 100 of the second embodiment acquires purpose information indicating the passenger's purpose for using the airport, and determines recommended information, which is information recommending the use of facilities at the airport, based on the purpose information. The information providing device 100 then outputs the determined recommended information to the passenger. This allows the information providing device 100 to encourage passengers to use facilities that correspond to their purpose for using the airport. In other words, the information providing device 100 can support the promotion of use of facilities at the airport.

Third Embodiment
Next, an information providing device according to a third embodiment will be described. In the third embodiment, an example will be described in which a passenger inputs destination information by operating a communication terminal 201. Note that some of the content that overlaps with the content described in the first and second embodiments will not be described.

[Details of information provision system 1001]
8 is a block diagram showing an example of the functional configuration of information providing system 1001. Information providing system 1001 includes information providing device 101, communication terminal 201, and signage terminal 202. Information providing system 1001 does not necessarily include imaging device 300. Information providing device 101 is connected to communication terminal 201 and signage terminal 202 so as to be able to communicate with them.

The communication terminal 201 comprises an output unit 210, a reception unit 220, and a location information control unit 230. The reception unit 220 receives input of various information from the passenger. For example, the reception unit 220 receives input of destination information from the passenger. The reception unit 220 may also receive input of personal information. Figure 9 is a diagram showing an example of personal information. In the example of Figure 9, the personal information includes passenger identification information, name, age, gender, nationality, address, occupation, and group composition. Note that group composition is information regarding the passengers accompanying the passenger when using the airport.

Furthermore, the reception unit 220 may accept input of ticket information. Ticket information is information regarding a flight on which a passenger is boarding. The ticket information may include information indicating the departure point, departure time, arrival point, and arrival time of the flight on which the passenger is boarding. In other words, the reception unit 220 may accept input of information indicating the departure point, departure time, arrival point, and arrival time of the flight on which the passenger is boarding. Figure 10 is a diagram showing an example of ticket information. In the example of Figure 10, the ticket information includes information that associates passenger identification information with information regarding outbound and return flights. For example, the information regarding the outbound flight specifies Narita, Tokyo as the departure point, 16:54 in Tokyo on March 1st as the departure time, Honolulu, USA as the arrival point, and 5:24 in the USA on March 1st as the arrival time. Note that ticket information is not limited to this example. For example, the ticket information may include information regarding a one-way flight.

The reception unit 220 may also accept input of an image including a passenger.

When the reception unit 220 receives input of various information, it transmits the input information and passenger identification information to the information providing device 101.

The location information control unit 230 controls the transmission of location information to the information providing device 101. Location information is information indicating the location where the device itself (i.e., the communication terminal 201) is located. For example, the location information control unit 230 may obtain, as location information, information measured using a GNSS (Global Navigation Satellite System), such as a GPS (Global Positioning System). In this case, the location information control unit 230 transmits, for example, the location information obtained using the GNSS to the information providing device 101. At this time, the location information control unit 230 transmits passenger identification information along with the location information.

In addition to this example, the location information control unit 230 may use a beacon to transmit location information to the information providing device 101. For example, the location information control unit 230 transmits a predetermined signal including passenger identification information. A receiver near the communication terminal 201 then receives the signal. The receiver identifies the location information of the communication terminal 201 in response to receiving the signal. The receiver may then transmit the location information of the communication terminal 201 together with the passenger identification information to the information providing device 101.

The information providing device 101 comprises a destination information acquisition unit 110, a determination unit 121, an output control unit 131, a ticket information acquisition unit 140, and a passenger information acquisition unit 150.

The destination information acquisition unit 110 acquires destination information from the communication terminal 201. The destination information is information that the reception unit 220 of the communication terminal 201 has received as input from the passenger. The destination information acquisition unit 110 may associate the acquired destination information with passenger identification information and store it, for example, in a storage device (not shown) that the information providing device 101 has.

The passenger information acquisition unit 150 acquires information about passengers. Specifically, the passenger information acquisition unit 150 acquires personal information about passengers from the communication terminal 201. This personal information is information that the reception unit 220 of the communication terminal 201 accepts as input from the passenger. In this way, the passenger information acquisition unit 150 acquires personal information about passengers through input by the passenger. The passenger information acquisition unit 150 is an example of a passenger information acquisition means.

In addition, the passenger information acquisition unit 150 acquires location information from the communication terminal 201. The passenger information acquisition unit 150 may acquire location information periodically. The location information acquired from the communication terminal 201 is regarded as passenger location information.

In addition, the passenger information acquisition unit 150 may acquire an image including a passenger from the communication terminal 201. The passenger information acquisition unit 150 may associate the image including the passenger with passenger identification information and store it in a storage device possessed by the information provision device 101.

The ticket information acquisition unit 140 acquires the passenger's ticket information. Specifically, the ticket information acquisition unit 140 may acquire the ticket information from the communication terminal 201. The ticket information is information that the reception unit 220 of the communication terminal 201 accepts as input from the passenger.

In addition, if a database of ticket information exists in an external device that can communicate with the information providing device 101, the ticket information acquisition unit 140 may acquire passenger ticket information from that database. In this case, the ticket information acquisition unit 140 acquires passenger ticket information from that database based on the passenger identification information acquired by the passenger information acquisition unit 150. In this way, if the ticket information acquisition unit 140 is able to acquire ticket information from a database, the reception unit 220 does not need to accept input of ticket information. However, information managed by airports differs from information managed by airlines. Ticket information is often managed by airlines. In other words, ticket information databases are often owned by airlines. Therefore, there is a possibility that airports will not be able to access the database. In that case, the reception unit 220 accepts input of ticket information.

In this way, the ticket information acquisition unit 140 acquires ticket information, which is information about the flight on which the passenger is boarding. The ticket information acquisition unit 140 is an example of a ticket information acquisition means.

The determination unit 121 determines the recommended information based on the purpose information. At this time, the determination unit 121 may further use ticket information to determine the recommended information. Specifically, the determination unit 121 may determine the recommended information based on the departure time of the flight on which the passenger is boarding, which is included in the ticket information. For example, assume that the determination unit 121 determines the recommended information based on the correspondence information in FIG. 5. Assume also that the passenger's purpose information is business. Here, if the time remaining until the departure time is 30 minutes or less, the passenger is unlikely to use a lounge. Therefore, the determination unit 121 may determine an advertisement for product A as the recommended information to be output when the time remaining until the departure time is 30 minutes or less. Furthermore, if the time remaining until the departure time is one hour or more, the passenger is likely to use a lounge compared to when the time remaining is 30 minutes or less. Therefore, the determination unit 121 may determine a guide to using the lounge as the recommended information to be output when the time remaining until the departure time is one hour or more. In this way, the determination unit 121 may determine the recommended information based on the ticket information and in accordance with the time remaining until the departure time of the flight that the passenger is boarding.

Furthermore, it is assumed that the determination unit 121 determines recommended information based on the correspondence information in Figure 5. And, it is assumed that the passenger's purpose information is sightseeing. Here, when the passenger is at the departure point of the outbound journey, the possibility of purchasing a souvenir is low. Therefore, when the passenger is at the departure point of the outbound journey, the determination unit 121 may determine at least one of an advertisement for restaurant X and a coupon for the restaurant as the recommended information to be output. Furthermore, when the passenger is at the departure point of the return journey, the possibility of purchasing a souvenir is higher than when the passenger is at the departure point of the outbound journey. Therefore, the determination unit 121 may determine an advertisement for souvenir B as the recommended information to be output.

In this way, the determination unit 121 may determine recommended information based on the objective information and ticket information.

The determination unit 121 may also determine the recommended information using personal information. For example, the determination unit 121 may determine advertisements for different products depending on age, gender, nationality, and group composition.

The output control unit 131 outputs the determined recommended information to the communication terminal 201. At this time, the output control unit 131 may output the recommended information to the passenger if the passenger is at the airport. For example, if the passenger's location information indicates that the passenger is inside the airport, the output control unit 131 transmits the recommended information to the communication terminal 201. The output control unit 131 may also estimate that the passenger is at the airport if, for example, the passenger is using the airport to board a passenger plane and there are less than two hours left until the departure time. The output control unit 131 may also estimate that the passenger is at the airport if, for example, the passenger is arriving at the airport by passenger plane and there is up to one hour left after the arrival time. For example, if the output control unit 131 estimates that the passenger is at the airport, it transmits the recommended information to the communication terminal 201.

Figure 11 is a diagram showing an example of recommended information. In the example of Figure 11, recommended information is output to the display of the communication terminal 201. Specifically, an advertisement for product A is shown. Furthermore, an address showing details of the store selling product A is shown. Passengers can use the address to check further information.

The output control unit 131 may also output recommended information to a signage terminal 202 installed within a predetermined range from the passenger. For example, the output control unit 131 refers to the installation location of the signage terminal 202 and determines whether the signage terminal 202 is located within a predetermined range from the position indicated by the passenger's location information. If the signage terminal 202 is located within a predetermined range from the position indicated by the passenger's location information, the output control unit 131 identifies the signage terminal 202 as a device that outputs recommended information. For example, the output control unit 131 transmits recommended information to the identified signage terminal 202.

The output control unit 131 may also output recommended information to the passenger in a language corresponding to the passenger's nationality. For example, if the passenger's nationality is Japanese, the output control unit 131 outputs the recommended information in Japanese. For example, if the passenger's nationality is American, the output control unit 131 outputs the recommended information in English.

[Example of operation of information providing device 101]
Next, an example of the operation of the information providing device 101 will be described with reference to FIG.

Figure 12 is a flowchart illustrating an example of the operation of the information providing device 101. The destination information acquisition unit 110 acquires destination information from the communication terminal 201 (S201). The passenger information acquisition unit 150 acquires personal information from the communication terminal 201 (S202). The passenger information acquisition unit 150 also acquires ticket information from the communication terminal 201 (S203). Here, the destination information, personal information, and ticket information may each be information input by the passenger at the reception unit 220 of the communication terminal 201.

The determination unit 121 determines the recommended information (S204). At this time, the determination unit 121 determines the recommended information based on the objective information. The determination unit 121 may also determine the recommended information based on at least one of personal information and ticket information.

The passenger information acquisition unit 150 acquires location information from the communication terminal 201 (S205). This location information is regarded as the passenger's location information. Then, if the passenger's location information indicates that the passenger is at the airport ("Yes" in S206), the output control unit 131 identifies an output device (S207). Specifically, the output control unit 131 identifies the passenger's communication terminal 201. The output control unit 131 also identifies a signage terminal 202 installed within a predetermined range from the passenger's location. The output control unit 131 causes the identified communication terminal 201 and signage terminal 202 to output recommended information (S208).

If the passenger is not at the airport (No in S206), the information providing device 101 returns to processing S205.

Note that the operation of the information providing device 101 is not limited to this example. For example, after processing S203, the information providing device 101 may acquire location information and determine whether the passenger is at the airport. Then, if the passenger is at the airport, the information providing device 101 may determine recommended information and output the recommended information.

In this way, the information providing device 101 of the third embodiment may acquire the destination information by accepting input of the destination information from the passenger, and output the recommended information to the communication terminal 201 carried by the passenger. This allows the information providing device 101 to more reliably allow the passenger to check the recommended information.

Furthermore, the information providing device 101 of the third embodiment may acquire ticket information, which is information regarding the flight that the passenger is boarding, and determine recommended information based on the destination information and ticket information. For example, the information providing device 101 of the third embodiment may determine recommended information based on the ticket information and in accordance with the time remaining until the departure time of the flight that the passenger is boarding. Furthermore, the information providing device 101 of the third embodiment may acquire personal information including the passenger's nationality through input by the passenger, and output recommended information to the passenger in a language corresponding to the passenger's nationality. This allows the information providing device 101 to output more appropriate recommended information to the passenger.

[Modification 1]
The reception unit 220 of the communication terminal 201 may receive input of various information from the passenger through an application installed on the communication terminal 201. That is, the passenger inputs destination information, personal information, and ticket information through the application. At this time, the output unit 210 of the communication terminal 201 may output various information through the application. In this case, the output control unit 131 outputs recommended information to the passenger through the application.

Furthermore, the output control unit 131 may output to the passenger information regarding the flight the passenger is boarding. Information regarding the flight the passenger is boarding may be, for example, a notification informing the passenger that the flight's departure time is approaching, a notification regarding a delay to the flight, etc. The output control unit 131 may output information regarding the flight the passenger is boarding through the application. In this case, the output control unit 131 may output information regarding the flight the passenger is boarding to a customer who has input various information. In this way, the information providing device 101 can prompt the passenger to input various information instead of outputting information to the passenger.

<Fourth embodiment>
Next, an information providing device according to a fourth embodiment will be described. In the fourth embodiment, another example will be described in which a passenger inputs destination information by operating the communication terminal 201. Note that some of the content overlapping with the content described in the first, second, and third embodiments will not be described.

[Details of information provision system 1002]
13 is a block diagram showing an example of the functional configuration of information provision system 1002. Information provision system 1002 includes information provision device 101, communication terminal 201, signage terminal 202, printing device 203, and imaging device 300. Information provision device 101 is connected to communication terminal 201, signage terminal 202, and printing device 203 so as to be able to communicate with them.

The reception unit 220 of the communication terminal 201 accepts input of an image including a passenger. More specifically, the reception unit 220 accepts input of a facial image of the passenger. For example, if the communication terminal 201 has a photographing function, the reception unit 220 accepts input of a facial image of the passenger photographed by the communication terminal 201. The reception unit 220 may also accept input of a facial image photographed by the passenger using another photographing device, for example. The reception unit 220 then transmits the facial image and passenger identification information to the information providing device 102.

The imaging device 300 includes an imaging unit 310. In this embodiment, the imaging device 300 is installed together with the signage terminal 202 and the printing device 203. For example, the imaging device 300-1 is installed together with the signage terminal 202. Also, for example, the imaging device 300-2 is installed together with the printing device 203. In this embodiment, an example will be described in which the imaging device 300-1 is installed together with the signage terminal 202, and the imaging device 300-2 is installed together with the printing device 203. Note that "the imaging device 300-1 is installed together with the signage terminal 202" means that the imaging device 300-1 is installed near the signage terminal 202. For example, the imaging device 300-1 may be installed within a predetermined range from the signage terminal 202. The imaging device 300-1 may also be mounted on the signage terminal 202. Figure 14 is a diagram illustrating an example of a situation in which the imaging device 300-1 is installed together with the signage terminal 202. 14, for example, an image capturing device 300-1 may be installed in the signage terminal 202. That is, the information providing device 102 may output recommended information to passengers present near the signage terminal 202.

Similarly, "the image capture device 300-2 is installed together with the printing device 203" means that the image capture device 300-2 is installed near the printing device 203. Figure 15 is a diagram illustrating an example of a situation in which the image capture device 300-2 is installed together with the printing device 203. The example in Figure 15 shows a situation in which a passenger is paying at a convenience store or restaurant. As shown in Figure 15, for example, the image capture device 300-2 and the printing device 203 may be installed together with a POS register. In this case, the printing device 203 issues a receipt. In other words, the information providing device 102 may output recommended information to the passenger making the payment via the receipt issued at the time of payment.

The information providing device 102 comprises a destination information acquisition unit 110, a determination unit 122, an output control unit 132, a ticket information acquisition unit 140, a passenger information acquisition unit 150, and an identification unit 160.

The passenger information acquisition unit 150 acquires a facial image of the passenger from the communication terminal 201. The passenger information acquisition unit 150 then associates the facial image with passenger identification information and stores it in a storage device (not shown) possessed by the information provision device 102. At this time, the passenger information acquisition unit 150 may also associate the passenger's facial features extracted from the facial image with the passenger identification information and store them in the storage device.

The identification unit 160 identifies the passenger. Specifically, the identification unit 160 uses facial recognition technology to identify the passenger appearing in the captured image acquired from the image capture device 300. The facial recognition technology used may be known technology. For example, the identification unit 160 acquires the captured image from the image capture device 300-1. The identification unit 160 also extracts facial features of the person appearing in the captured image. The identification unit 160 then compares the extracted features with features extracted from the facial image stored in the storage device of the information provision device 102. The identification unit 160 identifies the passenger whose facial image matches the match as appearing in the captured image. At this time, the identification unit 160 may identify the passenger by identifying passenger identification information associated with the facial image that matches the match.

In this way, the identification unit 160 acquires captured images from the imaging device and identifies passengers based on the features extracted from the captured images. The identification unit 160 is an example of an identification means.

The determination unit 122 determines recommended information based on the purpose information of the passenger identified by the identification unit 160. For example, assume that the identification unit 160 identifies a passenger whose passenger identification information is 001. In this case, the determination unit 122 determines recommended information based on the purpose information whose passenger identification information is 001. Similarly, the determination unit 122 may determine recommended information based on the purpose information, personal information, and ticket information whose passenger identification information is 001. In this case, the identification unit 160 identifies the passenger based on the photographed image of the passenger and a pre-stored facial image, and the determination unit 122 identifies the purpose information, personal information, and ticket information of the photographed passenger. This indicates that the passenger's facial image and passenger identification information are stored in association with each other. In other words, the information providing device 102 uses facial recognition technology to identify the passenger's purpose information, personal information, and ticket information in order to determine recommended information.

The output control unit 132 outputs recommended information to the identified passenger. For example, if a passenger is identified from an image captured by the imaging device 300-1, the output control unit 132 causes the signage terminal 202 to output recommended information. Figure 16 is a diagram showing an example of recommended information. More specifically, Figure 16 is an example of recommended information output by the signage terminal 202. In this example, a guide to using the lounge is output as recommended information. Furthermore, as in this example, the recommended information may include a map showing the route from the location of the signage terminal 202 to the lounge.

Furthermore, for example, if a passenger is identified from an image captured by the imaging device 300-2, the output control unit 132 causes the printing device 203 to output recommended information. Figure 17 is a diagram showing another example of recommended information. More specifically, Figure 17 is an example of recommended information output by the printing device 203. In this example, a coupon is printed as recommended information on a receipt output by the printing device 203. In this way, the output control unit 132 may cause the printing device 203 at the facility used by the passenger to issue a form including the recommended information. Note that "printing device 203 at the facility used by the passenger" also includes receipts issued by POS systems at shops and restaurants within the airport, and boarding passes issued by systems that check passengers in for boarding.

The output control unit 132 may output the recommended information to an output device installed together with the photographing device 300 that captured the photographed image.

[Example of operation of information providing device 102]
Next, an example of the operation of the information providing device 102 will be described with reference to FIG.

Figure 18 is a flowchart illustrating an example of the operation of the information providing device 102. The processing of S301 to S303 is similar to the processing of S201 to S203 in Figure 12, so description thereof will be omitted.

The passenger information acquisition unit 150 acquires a facial image of the passenger (S304). The identification unit 160 acquires a captured image from the photographing device 300 (S305). If a passenger is identified from the captured image ("Yes" in S306), the determination unit 122 determines recommended information (S307). For example, the determination unit 122 determines recommended information based on the identified passenger's purpose information, personal information, and ticket information.

The output control unit 132 identifies an output device (S308). Specifically, it identifies an output device installed together with the photographing device 300 that captured the identified passenger image. The output control unit 132 then causes the identified output device to output the recommended information (S309).

If a passenger is not identified from the captured image ("No" in S306), the information providing device 102 returns to processing S305.

Note that the operation of the information providing device 102 is not limited to this example. For example, if a person is detected from the captured image in the processing of S306 but the passenger is not identified, the information providing device 102 may cause the output device to output random recommended information.

In this way, the information providing device 102 of the fourth embodiment acquires a captured image from a photographing device and identifies the passenger based on features extracted from the captured image. The information providing device 102 may then determine recommended information according to the purpose information of the identified passenger. This allows the information providing device 102 to determine the location of the passenger. Therefore, the information providing device 102 can more reliably provide recommended information to the identified passenger by outputting the recommended information to the signage terminal 202 or printing device 203 at the passenger's location.

[Modification 2]
The signage terminal 202, the image capturing device 300, and the information providing device 102 may be implemented as an integrated device. For example, the signage terminal 202 may be equipped with the image capturing device 300 and the information providing device 102.

Similarly, the printing device 203, the photographing device 300, and the information providing device 102 may be realized as an integrated device. For example, the printing device 203, the photographing device 300, and the information providing device 102 may be installed in a POS register.

Fifth Embodiment
Next, an information providing device according to a fifth embodiment will be described. In the fifth embodiment, an example of estimating passenger purpose information will be described. Note that some of the content overlapping with the content described in the first, second, third, and fourth embodiments will not be described.

[Details of the information provision system 1003]
19 is a block diagram showing an example of the functional configuration of information provision system 1003. Information provision system 1003 includes information provision device 103, signage terminal 202, printing device 203, and imaging device 300. Information provision system 1003 may further include reading device 400. Information provision device 103 is connected to signage terminal 202, printing device 203, imaging device 300, and reading device 400 so as to be able to communicate with them.

The imaging device 300 is installed together with the signage terminal 202 and the printing device 203. In this embodiment, the imaging device 300-1 is installed together with the signage terminal 202. The imaging device 300-2 is installed together with the printing device 203.

The reading device 400 is a device that reads a passenger's airline ticket or boarding pass. For example, the reading device 400 generates passenger ticket information by reading a code printed on the airline ticket or boarding pass. The reading device 400 then transmits the generated ticket information to the information providing device 103. The reading device 400 is installed, for example, together with the signage terminal 202 and the printing device 203.

As shown in FIG. 19, the information providing device 103 includes a destination information acquisition unit 111, a determination unit 123, an output control unit 133, a ticket information acquisition unit 141, and a passenger information acquisition unit 151.

The destination information acquisition unit 111 includes an image acquisition unit 1101 and an estimation unit 1102. The image acquisition unit 1101 acquires captured images from the image capture device 300. The estimation unit 1102 estimates passenger destination information from the captured images. Specifically, the estimation unit 1102 detects passengers from the captured images. The estimation unit 1102 also estimates passenger attributes, including the passenger's clothing, belongings, and group composition. The estimation unit 1102 then estimates the passenger's destination information based on the estimated passenger attributes. For example, if the passenger is wearing a suit or carrying a business bag, the estimation unit 1102 estimates that the passenger's destination information is business. For example, if the passenger's group is made up of family members, the estimation unit 1102 estimates that the passenger's destination information is tourism.

For example, passenger detection can be achieved by using a method of detecting people based on the differences between multiple captured images, i.e., background subtraction, but is not limited to this example. Passenger detection can be achieved by various known methods, such as a method of detecting human shapes. Furthermore, passenger attributes can be estimated from captured images by various known methods. For example, the estimation unit 1102 extracts features from the captured images. The features may be image features derived using HOG (Histograms of Oriented Gradients), SIFT (Scaled Invariance Feature Transform), machine learning, or the like. The estimation unit 1102 may estimate passenger attributes using an estimation model that inputs the extracted features. The estimation model is a model that learns the relationship between features extracted from captured images and passenger attributes. The estimation unit 1102 may input the extracted feature amount into an estimation model and estimate the information output from the estimation model as the attributes of the passenger.

In this way, the destination information acquisition unit 111 may acquire a photographed image of a passenger and acquire estimated destination information based on at least one of the clothing, possessions, and group composition of the passenger appearing in the photographed image.

The ticket information acquisition unit 141 acquires the passenger's ticket information. Specifically, the ticket information acquisition unit 141 acquires the ticket information from the reading device 400.

The passenger information acquisition unit 151 acquires the passenger's personal information. Specifically, the passenger information acquisition unit 151 acquires the personal information by estimating the passenger's personal information from the acquired ticket information. For example, assume that the ticket information indicates that the outbound flight is from Tokyo to Honolulu, and the return flight is from Honolulu to Tokyo. In this case, it is estimated that the passenger resides in Japan. Therefore, the passenger information acquisition unit 151 estimates that the passenger's nationality is Japanese. In this way, the passenger information acquisition unit 151 may acquire personal information including the passenger's nationality estimated based on the ticket information.

The determination unit 123 determines the recommended information based on the estimated purpose information. The determination unit 123 may also determine the recommended information using ticket information.

The output control unit 133 outputs recommended information to the passenger. Specifically, the recommended information is output to an output device installed together with the imaging device 300 that captured the image used to estimate the destination information. For example, if an image captured by imaging device 300-1 is used to estimate the destination information, the output control unit 133 outputs the recommended information to the signage terminal 202.

In addition, if the passenger's nationality is estimated by the passenger information acquisition unit 151, the output control unit 133 may output recommended information in a language corresponding to the estimated nationality.

[Example of operation of information providing device 103]
Next, an example of the operation of the information providing device 103 will be described with reference to FIG.

Figure 20 is a flowchart illustrating an example of the operation of the information providing device 103. The image acquisition unit 1101 acquires a captured image from the imaging device 300 (S401). If the estimation unit 1102 detects a passenger from the captured image ('Yes' in S402), the estimation unit 1102 estimates the passenger's attributes (S403). Then, the estimation unit 1102 estimates the passenger's purpose information based on the estimated attributes (S404). If no passenger is detected from the captured image ('No' in S402), the information providing device 103 returns to the processing of S401.

If ticket information is acquired by the ticket information acquisition unit 141 ("Yes" in S405), the passenger information acquisition unit 151 estimates the passenger's personal information (S406). If ticket information is not acquired by the ticket information acquisition unit 141 ("No" in S405), the information providing device 103 does not need to perform the processing of S406.

The determination unit 123 determines recommended information according to the objective information (S407). At this time, if ticket information is acquired, the determination unit 123 may further use the ticket information to determine the recommended information. The output control unit 133 identifies an output device (S408). Specifically, the output control unit 133 identifies an output device installed together with the imaging device 300 that captured the captured image used to estimate the objective information. Then, the output control unit 133 causes the identified output device to output the recommended information (S409). At this time, if personal information including nationality has been estimated, the output control unit 133 may cause the recommended information to be output in a language corresponding to the nationality.

Note that the operation of the information providing device 103 is not limited to this example.

In this way, the information providing device 103 of the fifth embodiment acquires captured images from the image capturing device 300 and acquires destination information estimated based on at least one of the clothing, possessions, and group composition of passengers appearing in the captured images. This allows the information providing device 103 to provide recommended information to passengers based on their destination information, even if the passenger's destination information is not known in advance.

Furthermore, the information providing device 103 of the fifth embodiment may acquire personal information including the passenger's nationality estimated based on ticket information, and output recommended information in a language corresponding to the passenger's nationality. This allows the information providing device 103 to provide recommended information in a language corresponding to the passenger's nationality even if the passenger's nationality is not known in advance.

[Modification 3]
The destination information acquisition unit 111 may further use ticket information to estimate the destination information. For example, suppose the ticket information indicates that the passenger is heading abroad. Furthermore, suppose the ticket information indicates that the passenger will return home a long time later (i.e., the return trip date is later than a predetermined period of time from the current date). In this case, suppose the estimation unit 1102 estimates that the passenger is a single person in the group based on the captured image. In such a case, the estimation unit 1102 may estimate that the destination information of the passenger is studying abroad.

<Example of hardware configuration of information providing device>

The functions of each component of the information providing device are realized in response to the processor 91 executing the program 98. The program 98 may be stored in the ROM 93. The program 98 may also be recorded on the storage medium 80 and read out using the drive device 97, or may be transmitted to the computer device 90 from an external device (not shown) via a network (not shown).

The input/output interface 95 exchanges data with peripheral devices (keyboard, mouse, display device, etc.) 99. The input/output interface 95 functions as a means for acquiring or outputting data. The bus 96 connects each component.

There are various variations in how an information providing device can be realized. For example, an information providing device can be realized as a dedicated device. Also, an information providing device can be realized based on a combination of multiple devices.

The scope of each embodiment also includes a processing method in which a program for realizing each component of the function of each embodiment is recorded on a storage medium, the program recorded on the storage medium is read as code, and the program is executed on a computer. In other words, a computer-readable storage medium is also included in the scope of each embodiment. Furthermore, the storage medium on which the above-mentioned program is recorded and the program itself are also included in each embodiment.
