DETAILED DESCRIPTION OF THE INVENTION

[0011] (Embodiment 1) First, a configuration example of a guidance display control device 30 that constitutes a guidance display control system 1 of the first embodiment will be described with reference to FIG.

[0012] FIG. 1 is a schematic diagram of the guidance display control device 30. As shown in FIG.

[0013] As shown in FIG. 1, the guidance display control device 30 includes an image acquisition means 32a for acquiring an image including a person passing through a ticket gate, a person identification means 32b for identifying the person based on the acquired image, and a display control means 32f for controlling a display device to display guidance information corresponding to the identified person.

[0014] Next, an example of the operation of the guidance display control device 30 configured as described above will be described.

[0015] FIG. 2 is a flowchart showing an example of the operation of the guidance display control device 30. As shown in FIG.

[0016] First, the image acquisition means 32a acquires an image including a person passing through a ticket gate (step S1). Next, the person identification means 32b identifies the person based on the acquired image (step S2). Next, the display control means 32f controls the display device to display guidance information corresponding to the identified person.

[0017] As described above, according to embodiment 1, when a user passes through a ticket gate, guidance information tailored to the user can be displayed near the ticket gate (for example, on a display device (display) installed near the ticket gate).

[0018] (Embodiment 2) Hereinafter, a guidance display control system 1 will be described in detail as a second embodiment of the present invention. Hereinafter, an image acquisition unit is used as the image acquisition means 32a. Hereinafter, this will be referred to as the image acquisition unit 32a. Furthermore, a person identification unit is used as the person identification means 32b. Hereinafter, this will be referred to as the person identification unit 32b. Furthermore, a display control unit is used as the display control means 32f. Hereinafter, this will be referred to as the display control unit 32f.

[0019] Hereinafter, a guidance display control system 1 according to a second embodiment of the present disclosure will be described.

[0020] FIG. 3 is a block diagram showing the configuration of the guidance display control system 1. As shown in FIG.

[0021] First, an overview of the guidance display control system 1 will be described.

[0022] When one or more users (for example, users U1 to U3) pass through a gateless ticket barrier 80, the guidance display control system 1 performs facial authentication on the users, and if the facial authentication is successful, displays guidance information corresponding to the users on a display provided near the ticket barrier 80. There are cases where multiple pieces of guidance information corresponding to multiple users are displayed on the display.

[0023] Guidance information is generated based on the destination information of the user. "Platform 4" in FIG. 3 is an example of guidance information generated based on the destination information of user U1. Symbol I1 in FIG. 3 is an example of guidance information corresponding to user U1 displayed on the display 51 of the display device 50. Guidance information may also be displayed on the floor where the user is walking. Symbol I2 in FIG. 3 is an example of guidance information corresponding to user U1 displayed on the floor in front of user U1.

[0024] The guidance information is displayed together with the avatar image AG (see FIG. 3). That is, the guidance information is displayed in association with the avatar image. For example, the guidance information is displayed superimposed on the avatar image AG (see FIG. 3). Alternatively, the guidance information may be displayed near the avatar image AG (not shown).

[0025] Facial authentication and display of guidance information are performed before the user passes through ticket gate 80, for example, when a user (e.g., user U1) walking toward ticket gate 80 reaches a position a predetermined distance (e.g., several meters) from ticket gate 80. Therefore, a user whose facial authentication is successful can check guidance information appropriate for that user while walking toward ticket gate 80. At that time, because the guidance information is displayed together with avatar image AG, even if multiple pieces of guidance information appropriate for multiple users are displayed on display 51 of display device 50, each user can easily identify the guidance information appropriate for that user by using the avatar image AG of that user as a landmark.

[0026] After the user passes through the ticket gate 80, the guidance display control system 1 notifies the user who has passed through the ticket gate 80 of the guidance information displayed on the display 51 of the display device 50 or information with the same content. Therefore, even after passing through the ticket gate 80, the user can check the guidance information appropriate for that user by displaying it on the display 71 of the mobile terminal 70 that the user carries.

[0027] Next, the guidance display control system 1 will be described in detail.

[0028] As shown in Figure 3, the guidance display control system 1 includes an authentication device 10, a predetermined system 20, a guidance display control device 30, a camera 40, a display device 50, a projection device 60, and a mobile terminal 70, which are capable of communicating with each other via a network NW (e.g., the Internet).

[0029] When the authentication device 10 receives an authentication request transmitted from the guidance display control device 30, it detects a facial area in the image included in the authentication request and extracts facial feature information based on the facial area. Then, the authentication device 10 compares the extracted facial feature information with the facial information database, and if the facial feature information matches (i.e., if the user is identified), it returns authentication success and the user ID of the identified user to the guidance display control device 30 that sent the authentication request. On the other hand, if the facial feature information does not match (i.e., if the user is not identified), it returns authentication failure to the guidance display control device 30 that sent the authentication request.

[0030] The predetermined system 20 is realized by, for example, a physical server or a virtual server. The predetermined system 20 includes a user information database 21 (see FIG. 3). The user information database 21 stores destination information, language information, an avatar image, and an email address in association with a user ID. The destination information is destination information of a user whose user ID corresponds to the destination information. The language information is information that specifies a readable language (e.g., a native language) of the user whose user ID corresponds to the language information. The avatar image is an image unique to each user. The email address is the email address of the user whose user ID corresponds to the email address. The destination information, language information, avatar image, and email address are stored (set) in advance in the user information database 21 by the user operating an information processing terminal such as a mobile terminal.

[0031] The predetermined system 20 is, for example, a station system installed within a station, but may also be installed outside the station. When the predetermined system 20 receives a destination acquisition request transmitted from the guidance display control device 30, it refers to the user information database 21, reads out the destination information and language information associated with the user ID included in the destination acquisition request from the user information database 21, and returns the read destination information and language information to the guidance display control device 30 that transmitted the destination acquisition request.

[0032] In addition, when the specified system 20 receives a guidance information generation request sent from the guidance display control device 30, it refers to a specified database (not shown) and generates guidance information up to the destination information included in the guidance information generation request in a language specified by the language information also included in the guidance information generation request, and returns the generated guidance information to the guidance display control device 30 that sent the guidance information generation request.

[0033] FIG. 4 is a system configuration diagram of the guidance display control device 30. As shown in FIG.

[0034] As shown in FIG. 4, the guidance display control device 30 includes a storage unit 31, a control unit 32, a memory 33, and a communication unit .

[0035] The storage unit 31 is a non-volatile storage unit such as a hard disk drive, a ROM, etc. The storage unit 31 stores a program 31a and an authentication result image 31b.

[0036] The program 31a is a program executed by the control unit 32 (processor). In Fig. 5(a), reference numeral 31b1 is an example of an authentication result image that is displayed when the authentication result is authentication failure. In Fig. 5(b), reference numeral 31b2 is an example of an authentication result image that is displayed when the authentication result is authentication success.

[0037] The control unit 32 includes a processor (not shown). The processor is, for example, a CPU (Central Processing Unit). There may be one processor or multiple processors. The processor executes a program 31a loaded from the storage unit 31 into a memory 33 (for example, a RAM) to function as an image acquisition unit 32a, a person identification unit 32b, an authentication result acquisition unit 32c, a destination information acquisition unit 32d, a guidance information generation unit 32e, and a display control unit 32f. Some or all of these may be realized by hardware.

[0038] The image acquisition unit 32a acquires an image (hereinafter also referred to as a captured image) including a user (person to be authenticated) in front of the ticket gate 80, captured by the camera 40. Specifically, the communication unit 34 receives the captured image transmitted from the camera 40, and the image acquisition unit 32a acquires the captured image received by the communication unit 34.

[0039] The person identification unit 32b identifies a user by face authentication, iris authentication, skeletal authentication, or biometric authentication. For example, in the case of face authentication, the person identification unit 32b transmits an authentication request to the authentication device 10 via the communication unit 34. The authentication request includes the captured image acquired by the image acquisition unit 32a.

[0040] The authentication result acquisition unit 32c acquires the result of face authentication executed by the authentication device 10. Specifically, the communication unit 34 receives the authentication result transmitted from the authentication device 10, and the authentication result acquisition unit 32c acquires the authentication result received by the communication unit 34.

[0041] The destination information acquisition unit 32d transmits a destination information acquisition request to the predetermined system 20, and acquires the destination information and language information returned by the predetermined system 20 in response. The destination information acquisition request includes the user ID of the user requesting it. Note that the destination information acquisition unit 32d may acquire destination information from anywhere, as long as it acquires destination information set in a predetermined application (e.g., a route guidance application) installed on the user's mobile terminal 70 or the like.

[0042] The guide information generating unit 32e transmits a guide information generation request to the predetermined system 20. The guide information generation request includes the destination information and language information acquired by the destination information acquiring unit 32d.

[0043] When the display control unit 32f receives a notification of successful authentication, it controls the display device 50 so that an authentication result image 31b2 (see FIG. 5(b)) indicating successful authentication is displayed on the display 51 of the display device 50. Furthermore, when the display control unit 32f receives a notification of successful authentication, it controls the projection device 60 so that an authentication result image 31b2 (see FIG. 5(b)) indicating successful authentication is displayed on the road surface ahead of the user U1. On the other hand, when the display control unit 32f receives a notification of unsuccessful authentication, it controls the display device 50 so that an authentication result image 31b1 (see FIG. 5(a)) indicating unsuccessful authentication is displayed on the display 51 of the display device 50. Furthermore, when the display control unit 32f receives a notification of unsuccessful authentication, it controls the projection device 60 so that an authentication result image 31b1 (see FIG. 5(b)) indicating unsuccessful authentication is displayed on the road surface ahead of the user U1.

[0044] Furthermore, when the display control unit 32f receives guidance information tailored to the user, it controls the display device 50 so that the received guidance information is displayed on the display 51 of the display device 50. Furthermore, when the display control unit 32f receives guidance information tailored to the user, it controls the projection device 60 so that the received guidance information is displayed on the road surface ahead of the user U1.

[0045] The communication unit 34 is a communication device for communicating with the authentication device 10, the predetermined system 20, the camera 40, the display device 50, the projection device 60, the mobile terminal 70, and the like via the network NW.

[0046] Camera 40 captures an image including a user (person to be authenticated) walking in the area in front of ticket gate 80 toward ticket gate 80. Camera 40 is installed, for example, near the passageway through which the user walks so that it can capture an image of the user's face, i.e., the face of the user walking toward ticket gate 80, from the front or nearly the front (i.e., so that it can capture an image at an angle suitable for face authentication). Camera 40 is, for example, a digital camera that is remotely controlled by guidance display control device 30, and continuously captures images of the area in front of ticket gate 80 and transmits the captured images (and the camera's identification information (such as a location ID)) to guidance display control device 30 via network NW.

[0047] The display device 50 includes a display 51 such as a liquid crystal display on which various information is displayed. The display 51 is disposed above the passageway through the ticket gate 80, across the passageway through which users walk.

[0048] As shown in Fig. 3, the projection device 60 is installed near the passageway along which the user walks. The projection device 60 is, for example, but not limited to, a liquid crystal projector. The projection device 60 receives a projection instruction from the guidance display control device 30 via the network NW, and projects the guidance information included in the projection instruction into a projection area (a projection area set on the floor in front of the user) included in the projection instruction.

[0049] The mobile terminal 70 is a mobile terminal carried by a user, such as a smartphone, and includes a display 71 on which various information is displayed.

[0050] Next, an example of operation of the guidance display control system 1 configured as above (before passing through the ticket gate) will be described.

[0051] FIG. 6 is a flowchart of an example of the operation of the guidance display control device 30 (after passing through the ticket gate).

[0052] An example of the operation when user U1 passes through the ticket gate 80 will be described below, as shown in FIG. 3. It is assumed below that user U1's destination information, language information, avatar image, and email address have been stored (registered) in advance in the predetermined system 20 (user information database 21). It is assumed that user U1 has previously performed a route search using a predetermined application (e.g., Navitime) installed on his / her mobile terminal 70, and that the result of this route search (e.g., platform number "Platform 4" in FIG. 8(a)) has been stored (registered) in the predetermined system 20 (user information database 21) as user U1's destination information. FIG. 8(a) is an example of a screen showing the results of a route search performed by user U1 using a predetermined application (e.g., Navitime) installed on his / her mobile terminal 70.

[0053] First, it is determined whether or not the ticket gate passage condition is met (step S10). This determination is made, for example, when user U1 reaches a position a predetermined distance (for example, several meters) from the ticket gate 80. For example, if user U1 has a ticket to the destination or has a charge balance of more than a predetermined amount, it is determined that the ticket gate passage condition is met.

[0054] Next, authentication processing (face authentication processing) is executed (step S11). Specifically, first, the image acquisition unit 32a acquires an image (captured image) including a user (person to be authenticated) in front of the ticket gate 80, captured by the camera 40. Next, the person identification unit 32b transmits an authentication request to the authentication device 10 via the communication unit 34. The authentication request includes the captured image acquired by the image acquisition unit 32a. Next, the authentication result acquisition unit 32c acquires the authentication result of the face authentication executed by the authentication device 10. If the authentication result is successful, the authentication result includes the user ID. In this manner, the authentication processing (face authentication processing) is executed.

[0055] Next, the authentication result received from the authentication device 10 is displayed on the display 51 of the display device 50 (step S12). This is realized by the display control unit 32f.

[0056] FIG. 5(a) is an example of an authentication result image 31b1 indicating an authentication failure, and FIG. 5(b) is an example of an authentication result image 31b2 indicating an authentication success.

[0057] When the display control unit 32f receives a message indicating successful authentication, the display control unit 32f controls the display device 50 so that an authentication result image 31b2 (see FIG. 5(b)) indicating successful authentication is displayed on the display 51 of the display device 50. At this time, the charge balance, etc. may be displayed on the display 51 of the display device 50. On the other hand, when the display control unit 32f receives a message indicating unsuccessful authentication, the display control unit 32f controls the display device 50 so that an authentication result image 31b1 (see FIG. 5(a)) indicating unsuccessful authentication is displayed on the display 51 of the display device 50.

[0058] Next, if the authentication result is successful face authentication (step S13: YES), destination information and language information are acquired (step S13). This is achieved by the destination information acquisition unit 32d. The destination information acquisition unit 32d transmits a destination information acquisition request to the predetermined system 20, and acquires the destination information and language information returned by the predetermined system 20 in response. The destination information acquisition request includes the user ID of the user requesting it.

[0059] Next, guidance information is generated (step S15). Specifically, the guidance information generation unit 32e transmits a guidance information generation request to the predetermined system 20, and acquires guidance information corresponding to the user that is returned by the predetermined system 20 in response. The guidance information generation request includes destination information and language information acquired by the destination information acquisition unit 32d. "Platform 4" and "To get to Yamanote Line car No. 4, go straight and take the stairs on the right" in FIG. 3 are examples of guidance information generated in Japanese when the language specified by the language information is Japanese. "Track no. 5" in FIG. 5(c) is an example of guidance information generated in English when the language specified by the language information is English. Note that the guidance information may be generated by the guidance display control device 30 (guidance information generation unit 32e) itself.

[0060] Next, guidance information is displayed on the display 51 of the display device 50 (step S16). This is achieved by the display control unit 32f. When the display control unit 32f receives guidance information tailored to the user, it controls the display device 50 so that the received guidance information is displayed on the display 51 of the display device 50. When the display control unit 32f receives guidance information tailored to the user, it controls the projection device 60 so that the received guidance information is displayed on the road surface ahead of the user U1. Note that the guidance information tailored to the user may be displayed on both the display 51 of the display device 50 and on the road surface ahead of the user U1, or may be displayed on only one of them.

[0061] Next, an example of the operation of the guidance display control system 1 configured as above (after passing through the ticket gate) will be described.

[0062] FIG. 7 is a flowchart of an example of operation of the predetermined system 20 (after passing through the ticket gate).

[0063] When the transmission timing arrives after the user passes through the ticket gate 80 (step S20: YES), the predetermined system 20 transmits a notification to the mobile device 70 carried by the user who passed through the ticket gate 80 (step S21). Specifically, the predetermined system 20 references the user information database 21 and transmits the notification to the email address corresponding to the user ID of the user who passed through the ticket gate 80. FIG. 8(b) is an example of a notification (guidance information tailored to the user) transmitted to the mobile device 70 and displayed on its display 71. The notification transmitted to the mobile device 70 carried by the user may be the screen itself shown in FIG. 8(a) or FIG. 8(b), or may be address information (e.g., a URL) for accessing the screen. In addition, in the case of FIG. 8(b), each sentence in the figure may be a push notification. Each notification in FIG. 8(b) is an example of a notification transmitted (push notification) to the mobile device 70 carried by the user according to time and location. These notifications (guidance displays) are sent as push notifications and displayed in real time on the display 71 of the mobile terminal 70, allowing the user to check the guidance displays without opening a dedicated page. Examples of notifications that can be displayed on the display 71 of the mobile terminal 70 include notifications of the platform number and car number to board, such as "You can make a quicker transfer by boarding car number 4 on platform 4, Yamanote Line," notifications that count down to the departure time in real time, such as "The train from platform 3 departs at 0:59," and notifications that provide seat availability information, such as "There are many vacant seats if you board car number 1 on platform 11, Sobu Line."

[0064] As described above, according to embodiment 2, when a user passes through the ticket gate 80, guidance information appropriate for the user (for example, guidance information I1, I2 shown in Figure 3) can be displayed near the ticket gate, for example, on a display device 50 (display 51) installed near the ticket gate or on the floor in front of the user.

[0065] Furthermore, according to the second embodiment, by providing guidance display tailored to the user (guidance linked to transfer guidance), it becomes possible for passersby to transfer and arrive at their destination without getting lost even at places they have never seen before.

[0066] Furthermore, according to the second embodiment, guidance displays tailored to the user are displayed on a display device 50 (display 51) installed near the ticket gate, making it easier for nearby users to speak up and resolve issues between themselves, thereby reducing the burden of providing guidance on the part of station staff.

[0067] Furthermore, according to the second embodiment, after passing through the ticket gate, it is possible to send a notification (notification of guidance information) to the mobile terminal carried by the user, so that the user can check the guidance information again after passing through the ticket gate.

[0068] Furthermore, according to the second embodiment, guidance displays tailored to the user are displayed in a language that the user can read, making it possible to provide support in the native language of inbound users.

[0069] As described above, according to the second embodiment, it is possible to reduce the labor required for station staff to provide guidance and improve convenience for users.

[0070] In the above examples, the program includes instructions (or software code) that, when loaded into a computer, cause the computer to perform one or more functions described in the embodiments. The program may be stored on a non-transitory computer-readable medium or a tangible storage medium. By way of example and not limitation, computer-readable medium or tangible storage medium includes random-access memory (RAM), read-only memory (ROM), flash memory, solid-state drive (SSD) or other memory technology, CD-ROM, digital versatile disc (DVD), Blu-ray® disc or other optical disk storage, magnetic cassette, magnetic tape, magnetic disk storage or other magnetic storage device. The program may also be transmitted on a transitory computer-readable medium or communication medium. By way of example and not limitation, transitory computer-readable medium or communication medium includes electrical, optical, acoustic, or other forms of propagated signals.

[0071] The present disclosure is not limited to the above-described embodiments, and can be modified as appropriate without departing from the spirit of the present disclosure. For example, in the above-described second embodiment, an example in which the display device 50 is installed in a gateless ticket gate 80 has been described, but the present disclosure is not limited to this, and the display device 50 may also be installed in a ticket gate with a gate (not shown). Furthermore, the ticket gate 80 may be configured to allow multiple users to pass through at the same time, or to allow multiple users to line up in a line and pass through sequentially.
