<System configuration>
With reference to FIG. 1, the hardware configuration of the mobile terminal (information processing device, computer) in the embodiment will be described. In the present embodiment, as the mobile terminal 10 used by the user, for example, a mobile phone (including a smartphone), a tablet terminal, a PDA (Personal Digital Assistants), a glasses-type wearable device, a navigation device, and the like can be used. The mobile terminal 10 includes, for example, a control unit 11, a communication unit 12, a storage unit 13, an operation unit 14, a display unit 15, a sensor 16, a speaker 17, and a camera 18. The control unit 11 further includes a CPU (Central Processing Unit) 11a, a memory 11b, and the like.

The control unit 11 controls the operation of each component of the mobile terminal 10 by the CPU 11a expanding the program stored in the storage unit 13 or the like into the memory 11b and executing the program, and also executes various information processing. Control. As a program, for example, there is a route guidance (navigation) application software (hereinafter, also referred to as a “route guidance application”) described later. Details of the information processing executed by the control unit 11 will be described later.

The communication unit 12 is a communication interface for communicating with an external device. For example, the communication unit 12 receives data and commands from an external device, and transmits the result of information processing by the mobile terminal 10 to the outside.

The storage unit 13 is a non-volatile storage device, and is configured by, for example, a semiconductor memory or the like. The storage unit 13 stores various programs and various data necessary for executing information processing in the control unit 11.

The operation unit 14 is a user interface for receiving a user's instruction of the mobile terminal 10 and outputting it to the control unit 11. The operation unit 14 is composed of, for example, a touch panel, operation keys, and the like.

The display unit 15 is a user interface for displaying the information processing result of the mobile terminal 10. The display unit 15 is configured by a display device using a liquid crystal display, an LED (Light Emitting Diode), or the like.

The sensor 16 is composed of various sensors. As the sensor 16, for example, a gyro sensor, an acceleration sensor, a geomagnetic sensor, a barometric pressure sensor, or the like can be used. The sensor 16 detects and outputs the direction and acceleration of the mobile terminal 10 in the three-axis direction, the rotation angle around the three axes, and the like.

The speaker 17 outputs various sounds such as voice, music, and sound effects according to the control of information processing by the control unit 11.

The camera 18 captures a peripheral image (including a moving image of the periphery) of the mobile terminal 10 in response to control of information processing by the control unit 11.

The functional configuration of the mobile terminal 10 in the embodiment will be described with reference to FIG. The mobile terminal 10 has, for example, a database 110, a route guidance unit 111, a positioning unit 112, an imaging unit 113, a direction detection unit 114, a traveling direction determination unit 115, and a display control unit 116 as functional configurations. These functions are realized, for example, by the CPU 11a in the control unit 11 expanding the program (route guidance application) stored in the storage unit 13 or the like into the memory 11b and executing the program. The details of each functional configuration included in the mobile terminal 10 will be described below.

The database 110 stores various data such as data necessary for information processing executed by the mobile terminal 10 and data generated by the information processing.

The route guidance unit 111 (route acquisition unit) acquires information on the optimum route from the departure point to the destination (hereinafter referred to as "guidance route") according to the route search condition input by the user, and the route guidance unit 111 (hereinafter referred to as "guidance route") is obtained. Is presented to the user via the display unit 15 or the like to provide route guidance (navigation) to the user. For example, the route guidance is performed according to the guidance route obtained as a result of selecting a route guidance item from the menu displayed after starting the route guidance application, inputting the route search condition, and searching.

Regarding the search for the guide route, the route guide unit 111 refers to, for example, map data stored in the database 110 (or acquired from an external device via the communication unit 12) according to the route search condition input by the user. , Acquire information on the guided route by executing a route search. Alternatively, the route search process according to the input route search condition is performed on the external information processing device side, and the route guidance unit 111 outputs the process result (guide route information) of the route search from the external information processing device. It may be acquired.

As the route search method, any method such as the label determination method or the Dijkstra method can be used. The optimum route means that the cost information from the starting point to the destination point is the minimum. The cost information of the link can be set according to the purpose, such as distance, required time, charge, other parameters, and any combination of various parameters.

The positioning unit 112 (position acquisition unit) acquires and outputs the current position (for example, latitude and longitude information) of the mobile terminal 10 (or the user of the mobile terminal 10). The positioning unit 112 may acquire the current position of the mobile terminal 10 by using, for example, an API (Application Programming Interface) included in the OS (operating system) installed in the mobile terminal 10.

The shooting unit 113 uses the camera 18 (shooting device) to shoot a peripheral image including the direction in which the camera 18 is facing (the direction of the optical axis of the camera 18). The mobile terminal 10 is provided with a camera 18 on a surface (rear surface) opposite to the surface on which the display unit 15 is provided in the housing, and an image taken by the camera 18 is displayed on the display unit 15. That is, when the user points the camera 18 in the traveling direction, the image in the traveling direction is displayed on the display unit 15.

The direction detection unit 114 detects the direction (first direction) in which the camera 18 is facing in the horizontal plane by combining the output values of the gyro sensor, the acceleration sensor, and the geomagnetic sensor included in the sensor 16. The direction in which the camera 18 is facing in the horizontal plane may be expressed by, for example, an angle with the north direction as the reference direction (0 degree). In the present embodiment, it is assumed that the user uses the route guidance application while pointing the camera 18 in the direction in which the user himself / herself is facing. In the following description, the direction in which the camera 18 is facing on the horizontal plane is referred to as "the direction in which the user is facing" for convenience.

The traveling direction determination unit 115 sets the direction in which a point that has traveled a predetermined distance from the point indicating the current location on the guidance route as a "direction in which the user should travel" (second direction). decide. The current position acquired by the positioning unit 112 may actually include some errors. Therefore, the point indicating the current location on the guidance route may be, more specifically, the point closest to the current location of the mobile terminal 10 on the guidance route (that is, the point where the current location is matched on the guidance route).

The display control unit 116 controls the display of various information and images to be displayed on the display unit 15. For example, the display control unit 116 controls to display the guide route and the current position of the mobile terminal 10 on the map image. Further, the display control unit 116 superimposes and displays a virtual object on the peripheral image captured by the photographing unit 113. The virtual object is, for example, an object indicating the direction in which the user should go.

Further, in the display control unit 116, the direction in which the user detected by the direction detection unit 114 is facing is substantially the same as the direction in which the user determined by the traveling direction determination unit 115 should go or the direction along the guidance route. If so, the virtual object may be displayed as an object indicating the direction in which the user should go. On the other hand, when the direction in which the user is facing cannot be said to be substantially the same as the direction in which the user should go or the direction along the guidance route (for example, when the direction is opposite to the direction in which the user should go). , As a virtual object, an object indicating that the user is pointing in a direction different from the direction in which the user should go may be displayed.

Further, when the distance between the point closest to the current location of the mobile terminal 10 and the current location of the mobile terminal 10 in the guidance route exceeds a predetermined distance, the display control unit 116 deviates from the guidance route as a virtual object. You may want to display an object that indicates that you are in place.

Further, the display control unit 116 is on the peripheral image taken by the photographing unit 113 while the current position of the mobile terminal 10 is inside a predetermined range (for example, a radius of 25 meters or a radius of 50 meters) from the departure place. When the current position of the mobile terminal 10 moves to the outside of a predetermined range from the departure point, the virtual object may be continuously displayed on the map. That is, the display control unit 116 does not always display the screen on which the virtual object is superimposed on the peripheral image on the display unit 15, but the current position of the mobile terminal 10 is outside the predetermined range from the departure point. A screen for displaying a virtual object superimposed on a peripheral image may be displayed on the display unit 15 only until the image is moved to.

Further, the display control unit 116 may display on the display unit 15 both a screen in which a virtual object is superimposed on a peripheral image and a map screen in which a guide route is superimposed. In the following explanation, displaying a virtual object on top of a peripheral image is called "AR display", and the range within a predetermined range from the departure point (the range in which the virtual object continues to be displayed on the peripheral image) is called "AR". Called "display area".

<Processing procedure>
FIG. 3 is a flowchart showing an example of a processing procedure in which the mobile terminal 10 performs AR display. The flowchart shown in FIG. 3 is started when the route guidance unit 111 of the mobile terminal 10 finishes searching for a guide route starting from the current position of the mobile terminal 10 and actually starts route guidance.

In step S101, the positioning unit 112 acquires the current position of the mobile terminal 10. At this time, the positioning unit 112 may acquire whether or not the accuracy of the measured current position of the mobile terminal 10 is lower than the predetermined accuracy. The accuracy (error) of the current position of the mobile terminal 10 can be obtained by using, for example, the API provided in the OS installed in the mobile terminal 10.

In step S102, the display control unit 116 confirms whether or not the current position of the mobile terminal 10 is within the AR display area. If the current position is outside the AR display area, the process proceeds to step S103. If the current position is within the AR display area, the process proceeds to step S104. Even if the current location of the mobile terminal 10 moves out of the AR display area, the display control unit 116 continues the AR display if the accuracy of the current position of the mobile terminal 10 is lower than a predetermined threshold value. You may try to do it. That is, when the accuracy of the current position of the mobile terminal 10 is lower than the predetermined threshold value, the display control unit 116 may proceed to the processing procedure of step S104 instead of the processing procedure of step S103.

In step S103, the display control unit 116 ends the AR display, and displays the map screen on the display unit 15 on the entire surface.

In step S104, the display control unit 116 determines whether or not the current position of the mobile terminal 10 is on the guide route. Since the current position acquired by the positioning unit 112 may contain an error, the display control unit 116 displays the current position on the guide route even if the current position is slightly away from the guide route. Judge that. Specifically, the display control unit 116 confirms whether or not the distance between the point closest to the current location of the mobile terminal 10 and the current location of the mobile terminal 10 on the guidance route is within a predetermined distance. If it is within a predetermined distance, it is determined that the current position is on the guide route, the current position is matched with the position closest to the current position on the guide route, and then the process proceeds to step S105. On the other hand, if the distance exceeds a predetermined distance, it is determined that the current position is not on the guide route (out of the guide route), and the process proceeds to step S108.

In step S105, the display control unit 116 determines whether or not to display an object indicating the direction in which the user should go on the peripheral image captured by the photographing unit 113. If it is displayed, the process proceeds to step S106, and if it is not displayed, the process proceeds to step S107. The display control unit 116 determines whether or not to display an object indicating the direction in which the user should go on the peripheral image based on a predetermined determination condition. The details of the determination condition will be described later.

In the processing procedure of step S106, the display control unit 116 superimposes and displays an object indicating the direction in which the user should go on the peripheral image. FIG. 6A shows a display example. The screen of the mobile terminal 10 is composed of a display area A200 (first area) for displaying AR and a display area A201 (second area) for displaying a guide route and a map. In the example of FIG. 6A, the display area A200 occupies the upper half of the screen, and the display area A201 occupies the lower half of the screen, but the present embodiment is not limited to this. For example, the upper half of the screen may be the display area A201 and the lower half of the screen may be the display area A200.

The object X1a is an arrow indicating the direction in which the user should go, and the object X1b is a message to the user. In the example of FIG. 6A, the direction in which the user is facing and the direction in which the user should go are almost the same, so the message "Please proceed as it is" is displayed.

In the processing procedure of step S107, the display control unit 116 superimposes and displays an object indicating that the user is facing a direction different from the direction in which the user should go on the peripheral image. A display example is shown in FIG. 6 (b). The object X2a is a mark indicating that the user is facing a direction different from the direction in which the user should go, and the object X2b is a message to the user. In the example of FIG. 6B, since the direction in which the user is facing is different from the direction in which the user should go, the message "The direction in which the user is heading is different" is displayed.

In the processing procedure of step S108, the display control unit 116 superimposes and displays an object indicating that the user is out of the guide route on the peripheral image. A display example is shown in FIG. 6 (c). The object X3a is a mark indicating that the user is facing a direction different from the direction in which the user should go, and the object X3b is a message to the user. In the example of FIG. 6 (c), the message "off the route" is displayed.

The processing procedure of steps S101 to S108 described above is repeatedly executed until the AR display is completed in the processing procedure of step S103.

Subsequently, in the processing procedure of step S105 of FIG. 3, the details of the determination conditions when displaying the direction in which the user should go on the peripheral image (when displaying the screen shown in FIG. 6A) will be described. The mobile terminal 10 may execute any one of the following determination conditions (No. 1), determination condition (No. 2), and determination condition (No. 3) as the determination condition.

(Judgment condition (1))
FIG. 4 is a diagram for explaining a determination condition (No. 1) when the direction in which the user should go is displayed on the peripheral image. In FIG. 4, the point P1 is a point indicating the current location on the guide route R. The point P2 is a point advanced from the point P1 by a predetermined distance according to the guide route R. The predetermined distance may be any distance, but may be, for example, several meters (1 m ahead, 2 m ahead, 3 m ahead, 4 m ahead, etc.). The direction D1 indicates the direction in which the camera 18 is facing (that is, the direction in which the user is facing) in the horizontal plane. The direction D2 indicates a direction in which a point P2 that has traveled a predetermined distance from the point P1 according to the guide route R with respect to the point P1 exists (that is, a direction in which the user should go).

In the determination condition (No. 1), when the direction D2 in which the user should go is included in the direction in a predetermined range with respect to the direction D1 in which the user is facing, the direction in which the user should go is set on the peripheral image. indicate. In the example of FIG. 4, the direction of the predetermined range is assumed to be 30 degrees to the left and right with respect to the direction D1. On the other hand, if the direction D2 in which the user should go is not included in the direction in a predetermined range with respect to the direction D1 in which the user is facing, it is displayed that the user is facing in a direction different from the direction in which the user should go. ..

In the case of FIG. 4A, the case of FIG. 4B, and the case of FIG. 4E, the direction D2 is included in the direction of 30 degrees to the left and right with respect to the direction D1. Therefore, as shown in FIG. 6A, the display control unit 116 superimposes and displays an object indicating the direction in which the user should go on the peripheral image.

In the case of FIG. 4 (c) and the case of FIG. 4 (d), the direction D2 is not included in the direction of 30 degrees to the left and right with respect to the direction D1. Therefore, as shown in FIG. 6B, the display control unit 116 superimposes and displays an object indicating that the user is facing a direction different from the direction in which the user should go on the peripheral image.

(Judgment condition (2))
In the determination condition (No. 2), in addition to the condition shown in the determination condition (No. 1), the direction D3 along the guide route is included in the direction in a predetermined range with respect to the direction D1 in which the user is facing. Even if there is, the direction in which the user should go is displayed on the peripheral image. That is, the determination unit condition (No. 2) includes either the direction D2 to be followed by the user or the direction D3 along the guide route in a predetermined range with respect to the direction D1 to which the user is facing. If so, the direction in which the user should go is displayed above the peripheral image. On the other hand, if both the direction D2 in which the user should go and the direction D3 along the guide route are not included in the direction in a predetermined range with respect to the direction D1 in which the user is facing, the user is in the direction to go. Show that you are facing in a different direction.

FIG. 5 is a diagram for explaining a determination condition (No. 2) when the direction in which the user should go is displayed on the peripheral image. In FIG. 5, the direction D3 indicates a direction along the guide route. Since the point P1, the point P2, the direction D1 and the direction D2 are the same as those in FIG. 4, the description thereof will be omitted.

In the case of FIG. 5A, the case of FIG. 5B, the case of FIG. 5D, and the case of FIG. 5E, the direction D2 and the direction are 30 degrees to the left and right with respect to the direction D1. At least one of D3 is included. Therefore, as shown in FIG. 6A, the display control unit 116 superimposes and displays an object indicating the direction in which the user should go on the peripheral image.

On the other hand, in the case of FIG. 5C, the direction D2 and the direction D3 are not included in the direction of 30 degrees to the left and right with respect to the direction D1. Therefore, as shown in FIG. 6B, the display control unit 116 superimposes and displays an object indicating that the user is facing a direction different from the direction in which the user should go on the peripheral image.

The embodiment has been described above. According to the present embodiment, in the AR display area with respect to the departure place, an object indicating the direction in which the user should go is superimposed on the peripheral image taken by the camera 18 of the mobile terminal 10, so that the user can use the user. , When starting navigation, it becomes possible to intuitively and surely grasp in which direction to start walking. As a result, even if it is difficult to determine which direction the camera is facing, such as when the navigation is started at the timing of going out from the basement to the ground or the timing of getting off the car, the camera 18 around itself. It is possible to intuitively and surely grasp the direction in which you should start walking just by shooting with. In addition, even a user who is not good at viewing a map can intuitively and surely grasp the direction in which he / she should start walking.

Further, according to the present embodiment, instead of displaying the guide route superimposed on the peripheral image, an object indicating the direction in which the user should go is displayed. As a result, the display content can be simplified as compared with displaying the guide route superimposed on the peripheral image, and the processing load of the mobile terminal 10 can be reduced. Further, from the user's point of view, it is possible to prevent deterioration of visibility due to superimposition of the guide route on the peripheral image.

<Modification example>
The display control unit 116 may proceed to the processing procedure of step S107 when the state of not satisfying the predetermined determination condition continues for a predetermined time in the processing procedure of step S105 of FIG. For example, when the direction in which the user is facing changes from the state of FIG. 4 (a) to the state of FIG. 4 (c), the display control unit 116 changes to the state of FIG. 4 (c) in FIG. 6 ( Instead of switching from the screen of FIG. 6 (b) to the screen of FIG. 6 (b), when the state of FIG. 4 (c) continues for a predetermined time (for example, 3 seconds, etc.), the screen of FIG. 6 (a) to FIG. 6 You may switch to the screen of (b). As a result, when the detection result of the direction detection unit 114 is unstable, the screen of FIG. 6A and the screen of FIG. 6B are frequently switched, and the visibility of the user deteriorates. It is possible to prevent it from being detected.

The direction in a predetermined range based on the direction in which the user is facing in the determination condition (No. 1) to the determination condition (No. 3) may be changed according to the shape of the guide route. For example, if the current position is within a predetermined distance (for example, within 1 m or within 10 m) from the corner existing in the guide route, the predetermined range is expanded (for example, expanded to 60 degrees to the left or right) or reduced (for example, 60 degrees to the left or right). For example, it may be reduced to 20 degrees to the left or right). Alternatively, a predetermined range to be used for the determination of the determination condition (No. 1) to the determination condition (No. 3) may be preset at each point on the guide route (for example, a point every 1 m). This makes it possible to flexibly control whether or not an object indicating the direction in which the user should go is easily displayed according to the shape of the guided route according to the shape of the guided route.

When the display control unit 116 ends the AR display in the processing procedure of step S103 in FIG. 3, the display control unit 116 may display the guide route superimposed on the peripheral image. For example, in the display area A200 of the screen shown in FIG. 6 (c), after erasing the object X3a and the object X3b, the guide route may be superimposed and displayed on the peripheral image.

The display control unit 116 may display AR on the entire screen. For example, in the screens shown in FIGS. 6A to 6C, the display area A200 may be displayed on the entire screen without displaying the display area A201.

The display control unit 116 may perform voice guidance according to the content of the AR display while performing the AR display. For example, while the screen shown in FIG. 6 (a) is displayed, the voice guidance "Please proceed as it is" is output from the speaker 17, and the speaker is displayed while the screen shown in FIG. 6 (b) is displayed. The voice guidance "The direction of travel is different" is output from 17, and the voice guidance "Out of the route" is output from the speaker 17 while the screen shown in FIG. 6 (c) is displayed. You may do it. In this case, the display control unit 116 may be referred to as a "control unit".

The display control unit 116 performs the AR display shown in FIGS. 6A to 6C when the mobile terminal 10 is in portrait orientation, and displays AR when the mobile terminal 10 is in landscape orientation. Instead of doing so, the guide route and the map may be displayed on the entire screen.

The display control unit 116 does not necessarily have to display the object X2a indicating that the user is facing a direction different from the direction in which the user should go, and / or the object X3a indicating that the user is out of the guide route. good. For example, the display control unit 116 may display the object X1a indicating the direction in which the user should go, regardless of the direction in which the user is facing.

The flowcharts, sequences, elements included in the embodiments, arrangements, materials, conditions, shapes, sizes, and the like described in the embodiments are not limited to those exemplified, and can be appropriately changed. Further, it is possible to partially replace or combine the configurations shown in different embodiments.

In the present embodiment, the "part" does not simply mean a physical means, but also includes a case where the function of the "part" is realized by software. Further, even if the function of one "part" or device is realized by two or more physical means or devices, the function of two or more "parts" or devices is realized by one physical means or device.
