DETAILED DESCRIPTION OF THE INVENTION

[0009] With reference to the drawings, a mobility system using an information processing terminal according to first to third embodiments will be described. Note that common parts in each drawing are given the same reference numerals, and duplicated explanations will be omitted. In each embodiment, the mobility system is a system that manages the operation of public buses traveling to and from a specific area. The information processing terminal is a terminal that is installed at a public bus stop and allows a user to request the dispatch of a public bus.

[0010] First Embodiment <Configuration of a mobility system using an information processing terminal according to the first embodiment> 1 is an overall diagram showing the configuration of a mobility system 1A using an information processing terminal according to Embodiment 1. The mobility system 1A includes an information processing terminal 10A and a mobility management device 20.

[0011] 2 is a block diagram showing the configuration of information processing terminal 10A. Information processing terminal 10A is installed at each bus stop, and includes touch panel 11, camera device 12, wireless communication unit 13, storage unit 14, CPU 15A, and speaker device 16.

[0012] The touch panel 11 functions as an input unit for inputting information of touch operations performed by a bus user, and also functions as a display unit for displaying information to be provided to the user. The camera device 12 captures an image of the face of a user standing in front of the information processing terminal 10A. The touch panel 11 and the camera device 12 are installed adjacent to each other. The wireless communication unit 13 performs wireless communication with the mobility management device 20.

[0013] The storage unit 14 has an output information storage unit 141. The output information storage unit 141 stores guidance images for guiding the user's line of sight, sound information for directing the user's attention to the guidance images, text information, and the like, which are to be displayed on the touch panel 11.

[0014] The CPU 15A is, for example, a CPU (Central Processing Unit) provided in a general-purpose microcomputer, and configures one or more of the following information processing units by installing and executing a predetermined information processing program.

[0015] The CPU 15A has a vehicle dispatch request processing unit 151, an authentication processing unit 152, and an output control unit 153A. When the vehicle dispatch request processing unit 151 acquires information on a public bus dispatch request input from the touch panel 11, it executes face authentication of the user who performed the input operation, and when it recognizes that the face authentication is successful, it transmits the input vehicle dispatch request information and identification information of the authenticated user to the mobility management device 20.

[0016] The authentication processing unit 152 analyzes the image captured by the camera device 12 and performs face authentication of the user.

[0017] The output control unit 153A generates predetermined display information based on the processing content executed by the dispatch request processing unit 151, and displays it on the touch panel 11, and also generates predetermined sound information and outputs it from the speaker device 16. When the authentication processing unit 152 performs face authentication of the user based on an instruction from the dispatch request processing unit 151, the output control unit 153A displays a guidance image for guiding the user's line of sight within a predetermined distance from the camera device 12 of the touch panel 11, and operates the displayed image.

[0018] The speaker device 16 outputs the sound information generated by the output control unit 153A.

[0019] The mobility management device 20 performs wireless communication with the information processing terminal 10A installed at each bus stop and with an on-board device (not shown) installed on a public bus traveling within the area to be managed. The mobility management device 20 instructs the public bus on a route in response to a dispatch request operation performed by a user on the information processing terminal 10A.

[0020] <Operation of the mobility system according to the first embodiment> As an example of the operation of the mobility system 1A, a case will be described in which a user U makes a request for dispatching a public bus at a bus stop using the information processing terminal 10A. When the information processing terminal 10A authenticates the user U as a public bus user, the information processing terminal 10A accepts the request for dispatching a public bus from the user U.

[0021] When requesting the dispatch of a public bus, the user U stands in front of the information processing terminal 10A and performs an operation on the touch panel 11 to instruct the execution of face authentication.

[0022] 3 is a flowchart showing the operation of the information processing terminal 10A when it performs face authentication. When the user U performs an operation on the touch panel 11 to instruct the execution of face authentication ("YES" in S1), the vehicle dispatch request processing unit 151 instructs the output control unit 153A to output information for performing face authentication.

[0023] When the output control unit 153A receives an instruction to output information for performing facial authentication from the dispatch request processing unit 151, it displays display information on the touch panel 11 notifying the start of facial authentication, and outputs sound information from the speaker device 16 notifying the start of facial authentication.

[0024] After a predetermined time (for example, several seconds) has elapsed since the output of information notifying the start of execution of face authentication, the output control unit 153A acquires a guidance image for guiding the line of sight of the user U from the output information storage unit 141, and displays the image within a predetermined distance from the camera device 12 of the touch panel 11 (S2). In this way, the output control unit 153A guides the line of sight of the user U to the vicinity of the camera device 12.

[0025] The output control unit 153A also controls the speaker device 16 to output sound information for directing the user U's attention to the guidance image (S3). The output control unit 153A also controls the touch panel 11 to display text information for directing the user U's attention to the guidance image within a predetermined distance from the guidance image (S4).

[0026] The output control unit 153A also displays, on the touch panel 11, numerical information that updates the time until the timing for the camera device 12 to perform photography as time passes, together with the guidance image.

[0027] Figure 4 is a screen layout diagram showing a state in which a guidance image P shown as a character, text information T ``Look over here!'' shown in a speech bubble shape to draw the user U's attention to the guidance image P, and numerical information N ``5'' are displayed within a range AR of a predetermined distance from the camera device 12 of the touch panel 11.

[0028] As shown in FIG. 4, the output control unit 153A may include information "Performing face authentication" in the text information T while the guidance image displayed on the touch panel 11 is in operation, which notifies the user that face authentication will begin.

[0029] The output control unit 153A updates the numerical information N as time passes, thereby starting a countdown to the timing for the camera device 12 to perform shooting (S5). During the countdown ("NO" in S7), the output control unit 153A guides the attention of the user U to the guidance image by, for example, making the character of the displayed guidance image P move as if waving its hand, vibrating the guidance image P slightly, or blinking the guidance image P, and outputting predetermined sound information in accordance with the movement (S6).

[0030] While the guidance image P is being displayed, the output control unit 153A may limit the display of images other than the guidance image P displayed on the touch panel 11 by fixing the display state, lowering the color contrast, or erasing them. This will attract the attention of the user U to the guidance image P, and make it easier for the user U to direct his or her gaze toward the camera device 12.

[0031] When the countdown numerical information reaches 0 ("YES" in S7), the output control unit 153A notifies the dispatch request processing unit 151 that it is time to take a photo. When the dispatch request processing unit 151 receives the notification that it is time to take a photo, it instructs the camera device 12 to take a photo (S8). When instructed to take a photo, the camera device 12 takes a photo of the face of the user U who is in front of the information processing terminal 10A, generates a face image, and transmits it to the authentication processing unit 152.

[0032] The authentication processing unit 152 analyzes the facial image of the user U acquired from the camera device 12 and performs facial authentication of the user U (S9). The authentication processing unit 152 may perform facial authentication using multiple images captured by the camera device 12 while the guidance image is displayed. This allows for more accurate facial authentication.

[0033] When the authentication processing unit 152 succeeds in face authentication of the user U, the dispatch request processing unit 151 generates notification information indicating that the authentication has been successful and displays it on the touch panel 11. When the notification information indicating that the authentication has been successful is displayed, the user U selects a bus stop at which to board and a bus stop at which to disembark on the touch panel 11 and performs an operation to request a dispatch of a bus.

[0034] The vehicle dispatch request processing unit 151 acquires information about the operation performed on the touch panel 11, adds identification information of the authenticated user U, and wirelessly transmits the information to the mobility management device 20 via the wireless communication unit 13.

[0035] Based on the information transmitted from the information processing terminal 10A, the mobility management device 20 determines the public bus that the user U will use to board from a specified bus stop and disembark at another specified bus stop, and transmits identification information of the determined public bus to the information processing terminal 10A and the onboard device of the determined public bus.

[0036] In the information processing terminal 10A, the dispatch request processing unit 151 acquires the identification information of the public bus acquired from the mobility management device 20 and displays it on the touch panel 11. By visually checking the information displayed on the touch panel 11, the user U can recognize which public bus to board.

[0037] Second Embodiment <Configuration of a mobility system using an information processing terminal according to the second embodiment> 5 is a block diagram showing the configuration of an information processing terminal 10B according to the second embodiment. The information processing terminal 10B has the same configuration as the information processing terminal 10A described in the first embodiment, except that a CPU 15B has a line-of-sight estimation unit 154, and therefore detailed descriptions of parts having the same functions will be omitted.

[0038] The gaze estimation unit 154 estimates the gaze direction of the user based on the face image of the user captured by the camera device 12.

[0039] The output information storage unit 141 stores information on a plurality of guidance images and information on a plurality of sounds.

[0040] Based on the user's line of sight direction estimated by line of sight estimation unit 154, output control unit 153B determines the output content of information for guiding the user's line of sight and outputs it.

[0041] <Operation of Mobility System According to Second Embodiment> FIG. 6 is a flowchart showing the operation of the information processing terminal 10B when it performs face authentication. When the user U performs an operation on the touch panel 11 to instruct execution of face authentication ("YES" in S11), the dispatch request processing unit 151 instructs the camera device 12 to take a photograph. When instructed to take a photograph, the camera device 12 takes a photograph of the face of the user U who is in front of the information processing terminal 10A, generates a facial image, and transmits the generated facial image to the line of sight estimation unit 154.

[0042] The gaze estimation unit 154 analyzes the facial image of the user U acquired from the camera device 12 and estimates the gaze direction of the user U (S12). The gaze estimation unit 154 also estimates the viewpoint position of the user U on the touch panel 11 based on the position and gaze direction of the user U (S13). The gaze estimation unit 154 sends information on the estimated viewpoint position of the user U to the output control unit 153B.

[0043] Based on the acquired information on the user's viewpoint position, the output control unit 153B determines the trajectory of moving the guidance image on the touch panel 11, the type of guidance image, and the type of sound information to be output together with the guidance image as output content of information for guiding the line of sight of the user U (S14). The output control unit 153B may determine these output contents based on the standing position of the user U.

[0044] The output control unit 153B acquires the determined type of guidance image P from the output information storage unit 141, displays it on the touch panel 11 at the start position of the determined trajectory, and moves it along the trajectory (S15). The output control unit 153B also outputs the determined type of sound information from the speaker device 16 (S16).

[0045] When outputting sound information, the output control unit 153B may output sound so that a virtual sound source is generated in the camera device 12 or the displayed guidance image. This allows the attention of the user U to be directed to the guidance image with higher accuracy.

[0046] The output control unit 153B determines whether the gaze of the user U is directed toward the camera device 12 based on the information on the user's viewpoint position acquired from the gaze estimation unit 154 (S17). When the output control unit 153B determines that the gaze of the user U is not directed toward the camera device 12 ("NO" in S17), it displays text information for directing the user U's attention to the guidance image on the touch panel 11 within a predetermined distance from the guidance image (S18).

[0047] The output control unit 153B also displays, on the touch panel 11 together with the guidance image, numerical information that updates with time the time until the timing for the camera device 12 to perform photography.

[0048] Figure 7A is a screen layout diagram showing the state in which the movement trajectory R1 of the guidance image P is displayed when the user U's viewpoint is on the left side of the touch panel 11 when viewed from the front of the information processing terminal 10B, and the text information T ``Look over here!'' and ``Facial recognition will be performed'' shown in a speech bubble shape to draw the user U's attention to the guidance image P, and the numerical information N ``5'' are displayed.

[0049] In FIG. 7A, the movement trajectory R1 is a route from the current estimated viewpoint position Q1 of the user U to a position Q2 within a range AR of a predetermined distance from the camera device 12 of the touch panel 11.

[0050] Figure 7B is a screen layout diagram showing the movement trajectory R2 of the guidance image P when the user U's viewpoint is on the right side of the touch panel 11 when viewed from the front of the information processing terminal 10B, and the text information T ``Look over here!'' and ``Facial recognition will be performed'', shown in a speech bubble shape to draw the user U's attention to the guidance image P, and the numerical information N ``5''.

[0051] In FIG. 7B, movement trajectory R2 is a route from user U's current estimated viewpoint position Q3 to position Q2 within a predetermined distance range AR from camera device 12 of touch panel 11.

[0052] While the guidance image P is being moved, the output control unit 153B may limit the display of other images of the guidance image P displayed on the touch panel 11 by fixing the display state, lowering the color contrast, or erasing them. This will attract the attention of the user U to the guidance image P, and make it easier for the user U to direct his or her gaze toward the camera device 12.

[0053] The subsequent processes executed in steps S21 to S23 are similar to the processes in steps S7 to S9 described in the first embodiment, and therefore detailed description thereof will be omitted.

[0054] The dispatch request processing unit 151 may instruct the camera device 12 to take a photograph when the guidance image reaches a predetermined display state, specifically, when the final point of the determined trajectory is reached.

[0055] Furthermore, when the user U performs an operation on the touch panel 11 to instruct the execution of face authentication, the output control unit 153B may move a guidance image on the touch panel 11 from within a predetermined distance from an operation unit operated by the user, for example, an operation button (not shown) displayed on the touch panel 11, to within a predetermined distance from the camera device 12. This makes it possible to guide the user's gaze from the position where it is estimated that the user's gaze is directed to the vicinity of the camera device 12.

[0056] Third Embodiment <Configuration of a mobility system using an information processing terminal according to the third embodiment> The information processing terminal 10C according to this embodiment has the same configuration as the information processing terminal 10A described in the first embodiment, and therefore detailed description of parts having the same functions will be omitted.

[0057] In this embodiment, the output control unit 153C of the information processing terminal 10C operates the guidance image so that it appears and disappears from the touch panel 11 within a predetermined distance from the camera device 12 of the touch panel 11 when performing face authentication of a user.

[0058] <Operation of Mobility System According to Third Embodiment> When the user U performs an operation on the touch panel 11 of the information processing terminal 10C to instruct the execution of face authentication, the processing in which the information processing terminal 10C displays a guidance image on the touch panel 11, outputs sound information, displays text information, and starts a countdown until the timing for the camera device 12 to perform photography is the same as steps S1 to S5 described in the first embodiment, and therefore a detailed description thereof will be omitted.

[0059] FIG. 8 is a flowchart showing the process that the output control unit 153C executes after starting the countdown until the timing for the camera device 12 to perform photography is reached.

[0060] When the output control unit 153C starts counting down to the timing for the camera device 12 to perform shooting, the output control unit 153C may limit the display of images other than the guidance image on the touch panel 11 by fixing the display state, lowering the color contrast, or erasing them. This will attract the attention of the user U to the guidance image P, making it easier for the user U to direct his or her gaze toward the camera device 12.

[0061] The output control unit 153C also causes the guidance image to repeat an appearance and disappearance action on the touch panel 11 a predetermined number of times within a predetermined distance from the camera device 12 of the touch panel 11 (S32 to S34).

[0062] 9A is a screen configuration diagram showing a state in which the guide image P is hidden from the touch panel 11. FIG. 9B is a screen configuration diagram showing a state in which about half of the guide image P appears on the touch panel 11. FIG. 9C is a screen configuration diagram showing a state in which the entire guide image P appears on the touch panel 11.

[0063] 9A → 9B → 9C → 9B → 9A → 9B..., the guidance image P appears and disappears from the touch panel 11. This draws the attention of the user U to the moving guidance image P, and the user U's gaze is directed toward the vicinity of the camera device 12.

[0064] The output control unit 153C may change the character of the next guidance image that appears every time the guidance image is hidden from the touch panel 11. Furthermore, the output control unit 153C may output predetermined sound information at the timing when the guidance image appears and disappears. This can further draw the attention of the user U to the guidance image.

[0065] When the guidance image appears and disappears a predetermined number of times (YES in S32), the process proceeds to step S7 described in the first embodiment. The processes executed after step S7 are the same as those in the first embodiment, and therefore detailed descriptions thereof will be omitted.

[0066] In the first to third embodiments described above, the output control units 153A, 153B, and 153C may limit the display of the guidance image by fixing the display state of the guidance image, lowering the color contrast, or erasing the guidance image while waiting for a user operation or while displaying other information that the user should pay attention to.

[0067] [Effects of the embodiment] As described above, in the information processing method according to this embodiment, an information processing terminal having a display unit installed adjacent to a camera device that captures a facial image used for facial authentication displays a guidance image for guiding the user's line of sight within a predetermined distance from the camera device on the display unit when performing facial authentication of a user, and activates the displayed guidance image.

[0068] This allows the user's face image to be captured while the user is looking at the camera device, making it possible to perform face authentication with high accuracy.

[0069] The information processing terminal may also estimate the user's gaze direction based on the user's face image captured by the camera device, and determine and output information for guiding the user's gaze based on the estimated user's gaze direction. This allows the user's gaze to be directed toward the camera device with even greater accuracy.

[0070] Furthermore, the information processing terminal may output information notifying the start of face authentication execution by at least one of a sound and a display during and / or before the operation of the guidance image, thereby more accurately directing the user's attention to the guidance image.

[0071] Furthermore, when performing face authentication of a user, the information processing terminal may output information notifying the start of execution of face authentication, and may start displaying or operating a guidance image after a predetermined time has elapsed since outputting the notification information, which makes it easier for the user to recognize the guidance image.

[0072] The information processing terminal may also move the guidance image on the display unit from within a predetermined distance from the operation unit operated by the user to within a predetermined distance from the camera device, move it so that it appears and disappears, blink, or move it in a direction determined based on at least one of the user's position and line of sight, thereby more accurately directing the user's attention to the guidance image.

[0073] Furthermore, when the guidance image is active, the information processing terminal may fix the display state of other images on the display unit, reduce the color contrast, or erase them, thereby more accurately directing the user's attention to the guidance image.

[0074] The information processing terminal may also display, together with the guidance image, numerical information that updates over time to indicate the time until the camera device takes a photograph, which allows the user to recognize the timing for taking a photograph and to easily orient themselves in the direction of the camera device.

[0075] Furthermore, the camera device may perform photography when the numerical information becomes 0 or when the guidance image is in a predetermined display state. This allows the user to recognize the timing of photography with even greater accuracy.

[0076] Furthermore, the information processing terminal may output a sound so that a virtual sound source is generated in the camera device or the guidance image, thereby enabling the user's attention to be directed to the guidance image with even greater accuracy.

[0077] The information processing terminal may also perform face authentication using a plurality of images captured by the camera device while the guidance image is displayed, thereby enabling face authentication to be performed with even greater accuracy.

[0078] Furthermore, the information processing terminal may limit the display of the guidance image while waiting for a user operation or while displaying other information that the user should pay attention to, thereby making it easier for the user to view information with a high priority.

[0079] Although several embodiments have been described, the embodiments can be modified or varied based on the above disclosure. All components of the above embodiments and all features described in the claims may be individually extracted and combined, unless they contradict each other.

[0080] Although the embodiments of the present invention have been described above, the descriptions and drawings that form part of this disclosure should not be understood to limit the present invention.
