<System configuration>
With reference to FIG. 1, the hardware configuration of a mobile terminal (information processing apparatus, computer) in the embodiment will be described. In the present embodiment, for example, a mobile phone (including a smartphone), a tablet terminal, a PDA (Personal Digital Assistant), a glasses-type wearable device, a navigation device, or the like can be used as the mobile terminal 10 used by the user. 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 and a memory 11b.

  The control unit 11 controls the operation of each component of the mobile terminal 10 by the CPU 11a expanding and executing the program stored in the storage unit 13 or the like in the memory 11b, and executes various information processing. Control. Examples of the program include route guidance (navigation) application software (hereinafter also referred to as “route guidance application”). Details of the information processing executed in 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 includes, for example, a semiconductor memory. The storage unit 13 stores various programs and various data necessary for execution of information processing in the control unit 11.

  The operation unit 14 is a user interface for receiving an instruction from the user of the mobile terminal 10 and outputting the instruction to the control unit 11. The operation unit 14 includes, for example, a touch panel and operation keys.

  The display unit 15 is a user interface for displaying information processing results by the mobile terminal 10. The display unit 15 is configured by a display device using liquid crystal, 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, an atmospheric 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 triaxial direction and the rotation angle around the triaxial direction.

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

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

  With reference to FIG. 2, the functional configuration of the mobile terminal 10 in the embodiment will be described. The mobile terminal 10 includes, for example, a database 110, a route guide unit 111, a positioning unit 112, a photographing 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, in the control unit 11 by the CPU 11a developing and executing a program (route guidance application) stored in the storage unit 13 or the like in the memory 11b. Below, the detail of each function structure with which the portable terminal 10 is provided is demonstrated.

  The database 110 stores various data such as data necessary for information processing executed in 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 (hereinafter referred to as “guidance route”) from the departure point to the destination according to the route search condition input by the user, and the guidance route. Is presented to the user via the display unit 15, and route guidance (navigation) is performed for the user. For example, the route guidance is performed according to a guidance route obtained as a result of searching by selecting a route guidance item from a menu displayed after starting the route guidance application and inputting a route search condition.

  Regarding the search for the guidance route, the route guidance 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. Information on the guide route is acquired by executing a route search. Alternatively, a route search process according to the input route search condition is performed on the external information processing apparatus side, and the route guidance unit 111 obtains the result of the route search process (guidance route information) from the external information processing apparatus. It is good also as acquiring.

  As a route search method, an arbitrary method such as a label determination method or a Dijkstra method can be used. The optimal 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 a distance, a required time, a fee, other parameters, and an arbitrary 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) provided in an OS (operating system) installed in the mobile terminal 10.

  The imaging unit 113 uses the camera 18 (imaging device) to capture a peripheral image including the direction in which the camera 18 is facing (the optical axis direction of the camera 18). The mobile terminal 10 includes a camera 18 on a surface (back surface) opposite to the surface on which the display unit 15 is provided in the housing, and an image captured by the camera 18 is displayed on the display unit 15. That is, when the user points the camera 18 in the traveling direction, an 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 faces 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 faces in the horizontal plane may be expressed by an angle with the north direction as a reference direction (0 degrees), for example. 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 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 uses, as a reference, a point indicating the current location on the guidance route, and a direction where there is a point that has traveled a predetermined distance from the point according to the guidance route is defined as a “direction in which the user should travel” (second direction). decide. Note that 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 a point closest to the current location of the mobile terminal 10 on the guidance route (that is, a point where the current location is matched with the guidance route).

  The display control unit 116 controls display of various information and images displayed on the display unit 15. For example, the display control unit 116 controls to display the guidance route and the current position of the mobile terminal 10 on the map image. In addition, the display control unit 116 displays the virtual object on the peripheral image captured by the imaging unit 113 in an overlapping manner. The virtual object is, for example, an object indicating a direction in which the user should proceed.

  In addition, the display control unit 116 substantially matches the direction in which the user is detected detected by the direction detection unit 114 with the direction determined by the traveling direction determination unit 115 and the direction along the guidance route. In this case, an object indicating the direction in which the user should proceed may be displayed as a virtual object. On the other hand, when it cannot be said that the direction in which the user is facing generally coincides with the direction in which the user should travel or the direction along the guidance route (for example, when the direction is opposite to the direction in which the user should travel). An object indicating that the user is facing a direction different from the direction in which the user should proceed may be displayed as the virtual object.

  Further, the display control unit 116 determines that the user has deviated from the guidance route as a virtual object when the distance between the location closest to the current location of the mobile terminal 10 in the guidance route and the current location of the mobile terminal 10 exceeds a predetermined distance. You may make it display the object which shows that it exists in a place.

  In addition, the display control unit 116 displays the upper image of the peripheral image captured by the imaging 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. If the current position of the mobile terminal 10 moves outside the predetermined range from the departure place, only the map display may be performed so that the virtual object is continuously displayed. That is, the display control unit 116 does not always display the screen for displaying the virtual object on the surrounding image on the display unit 15, but the current position of the mobile terminal 10 is outside the predetermined range from the departure place. The screen for displaying the virtual object on the surrounding image may be displayed on the display unit 15 only during the period until it moves to.

  In addition, the display control unit 116 may display both a screen on which the virtual object is superimposed on the peripheral image and a map screen on which the guidance route is superimposed on the display unit 15. In the following description, displaying a virtual object superimposed on a peripheral image is referred to as “AR display”, and within a predetermined range from the departure point (a range in which the virtual object is continuously displayed on the peripheral image) is indicated by “AR This is called “display area”.

<Processing procedure>
FIG. 3 is a flowchart illustrating 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 guidance route with the current position of the mobile terminal 10 as a departure point and actually starts route guidance.

  In step S <b> 101, 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 a predetermined accuracy. The degree of accuracy (error) of the current position of the mobile terminal 10 can be obtained by using, for example, an API provided in the OS installed in the mobile terminal 10.

  In step S102, the display control unit 116 checks 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. Note that the display control unit 116 continues the AR display when the accuracy of the current position of the mobile terminal 10 is lower than a predetermined threshold even when the current location of the mobile terminal 10 moves outside the AR display area. You may make it do. That is, when the accuracy of the current position of the mobile terminal 10 is lower than the predetermined threshold, 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 entire map screen on the display unit 15.

  In step S104, the display control unit 116 determines whether or not the current position of the mobile terminal 10 is on the guidance route. Since there is a possibility that an error is included in the current position acquired by the positioning unit 112, the display control unit 116 may display the current position on the guidance route even when the current position is slightly away from the guidance route. It is judged that. Specifically, the display control unit 116 checks whether or not the distance between the location closest to the current location of the mobile terminal 10 and the current location of the mobile terminal 10 in the guidance route is within a predetermined distance. If it is within the predetermined distance, it is determined that the current position is on the guide route, and 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 the predetermined distance, it is determined that the current position is not on the guidance route (departs from the guidance route), and the process proceeds to step S108.

  In step S <b> 105, the display control unit 116 determines whether or not to display an object indicating the direction in which the user should travel on the peripheral image captured by the imaging unit 113. If so, the process proceeds to step S106. If not, the process proceeds to step S107. Note that the display control unit 116 determines whether or not to display an object indicating the direction in which the user should travel on the surrounding image based on a predetermined determination condition. Details of the determination condition will be described later.

  In the processing procedure of step S106, the display control unit 116 displays an object indicating the direction in which the user should travel on the surrounding image. A display example is shown in FIG. The screen of the mobile terminal 10 includes a display area A200 (first area) for displaying AR, and a display area A201 (second area) for displaying a guidance 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 this 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 proceed, and the object X1b is a message to the user. In the example of FIG. 6A, since the direction in which the user is facing and the direction in which the user should proceed are substantially the same, the message “Please proceed as it is” is displayed.

  In the processing procedure of step S107, the display control unit 116 displays an object indicating that the user is facing a direction different from the direction in which the user should travel on the surrounding image. FIG. 6B shows a display example. The object X2a is a mark indicating that the user is facing a direction different from the direction in which the user should proceed, 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 is to travel, the message “The traveling direction is different” is displayed.

  In the processing procedure of step S108, the display control unit 116 displays an object indicating that the user is outside the guidance route on the surrounding image. A display example is shown in FIG. The object X3a is a mark indicating that the user is facing a direction different from the direction in which the user should proceed, and the object X3b is a message to the user. In the example of FIG. 6C, the message “I am out of route” is displayed.

  The processing procedure from step S101 to step 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 in FIG. 3, details of the determination condition when the direction in which the user should proceed is displayed on the peripheral image (when the screen shown in FIG. 6A is displayed) will be described. The portable terminal 10 may execute any one of the following determination conditions (part 1), determination conditions (part 2), and determination conditions (part 3) as the determination conditions.

(Judgment condition (1))
FIG. 4 is a diagram for explaining a determination condition (part 1) when the direction in which the user should proceed is displayed on the peripheral image. In FIG. 4, a point P <b> 1 is a point indicating the current location on the guidance 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, about 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 in the horizontal plane (that is, the direction in which the user is facing). 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 travel).

  In the determination condition (part 1), when the direction D2 to be traveled by the user is included in the direction of the predetermined range with respect to the direction D1 to which the user is facing, the direction in which the user should travel is displayed on the peripheral image. indicate. The direction of the predetermined range is assumed to be 30 degrees left and right with respect to the direction D1 in the example of FIG. On the other hand, when the direction D2 to which the user should proceed is not included in the direction of the predetermined range based on the direction D1 to which the user is facing, the user is displayed indicating that he is facing a direction different from the direction to proceed. .

  In the case of FIG. 4 (a), the case of FIG. 4 (b), and the case of FIG. 4 (e), the direction D2 is included in the direction 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 travel on the surrounding image.

  In the case of FIG. 4C and the case of FIG. 4D, the direction D2 is not included in the direction 30 degrees 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 proceed on the peripheral image.

(Judgment condition (2))
In the determination condition (part 2), in addition to the condition shown in the determination condition (part 1), the direction D3 along the guide route is included in the direction of a predetermined range based on the direction D1 the user is facing. Even if it is, the direction which a user should advance is displayed on a surrounding image. That is, in the determination unit condition (No. 2), either the direction D2 that the user should travel or the direction D3 along the guidance route is included in the direction of the predetermined range based on the direction D1 that the user is facing. When the user is present, the direction in which the user should proceed is displayed on the peripheral image. On the other hand, when both the direction D2 that the user should travel and the direction D3 along the guidance route are not included in the direction of the predetermined range with respect to the direction D1 that the user is facing, Show that you are facing in a different direction.

  FIG. 5 is a diagram for explaining the determination condition (part 2) when the direction in which the user should proceed is displayed on the peripheral image. In FIG. 5, a direction D3 indicates a direction along the guide route. The point P1, the point P2, the direction D1, and the direction D2 are the same as those in FIG.

  In the case of FIG. 5 (a), the case of FIG. 5 (b), the case of FIG. 5 (d), and the case of FIG. 5 (e), the direction D2 and the direction in the direction 30 degrees 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 travel on the surrounding image.

  On the other hand, in the case of FIG. 5C, the direction D2 and the direction D3 are not included in the direction 30 degrees 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 proceed on the peripheral image.

  The embodiment has been described above. According to the present embodiment, since the object indicating the direction in which the user should proceed is superimposed on the peripheral image captured by the camera 18 of the mobile terminal 10 in the AR display area based on the departure place, the user can When starting navigation, it is possible to intuitively and surely grasp in which direction to start walking. Thus, for example, even when it is difficult to determine which direction it is facing, such as when navigation starts at the timing of getting out of the ground from the ground or when getting out of the car, the camera 18 By simply shooting with, you can intuitively and reliably grasp the direction to start walking. Further, even a user who is not good at seeing a map can intuitively and surely grasp the direction to start walking.

  Further, according to the present embodiment, an object indicating a direction in which the user should proceed is displayed instead of displaying a guidance route on a surrounding image. As a result, the display content can be simplified as compared to displaying the guidance route on the surrounding image, and the processing load on the mobile terminal 10 can be reduced. In addition, even when viewed from the user's viewpoint, it is possible to prevent deterioration of visibility due to the guidance route being superimposed on the surrounding image.

<Modification>
The display control unit 116 may proceed to the processing procedure of step S107 when a state in which the predetermined determination condition is not satisfied continues for a predetermined time in the processing procedure of step S105 in FIG. For example, when the direction in which the user is facing changes from the state shown in FIG. 4A to the state shown in FIG. 4C, the display control unit 116 changes to the state shown in FIG. Instead of switching from the screen of a) to the screen of FIG. 6B, when the state of FIG. 4C continues for a predetermined time (for example, 3 seconds), the screen of FIG. You may make it switch to the screen of (b). Thereby, when the detection result of the direction detection unit 114 is unstable, the screen in FIG. 6A and the screen in FIG. 6B are frequently switched, and the visibility of the user is deteriorated. Can be prevented.

  In the determination condition (part 1) to the determination condition (part 3), the direction in a predetermined range based on the direction in which the user is facing may be changed according to the shape of the guide route. For example, when the current position is within a predetermined distance (for example, within 1 m or within 10 m) from a corner existing in the guide route, the predetermined range is expanded (for example, expanded to 60 degrees on the left and right, etc.) or reduced ( For example, it may be reduced to 20 degrees on the left and right. Or the predetermined range which should be used for determination of the determination conditions (the 1)-the determination conditions (the 3) may be preset at each point (for example, a point for every 1 m) on the guidance route. This makes it possible to flexibly control whether or not an object indicating the direction in which the user should proceed is easily displayed according to the shape of the guidance route according to the shape of the guidance route.

  When the AR display is terminated in the processing procedure of step S103 in FIG. 3, the display control unit 116 may display the guidance route on the surrounding image. For example, in the display area A200 of the screen shown in FIG. 6C, after deleting the object X3a and the object X3b, the guidance route may be displayed so as to overlap the surrounding image.

  The display control unit 116 may perform AR display 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. 6A is displayed, a voice guidance “Proceed as it is” is output from the speaker 17, and while the screen shown in FIG. 6B is displayed, the speaker A voice guidance saying “The direction of travel is different” is output from the speaker 17, and while the screen shown in FIG. 6C is displayed, a voice guidance saying “I am off the route” is output from the speaker 17. It may be. 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 the vertical orientation, and displays the AR display when the mobile terminal 10 is in the horizontal orientation. You may make it display a guidance route and a map on the whole screen, without performing.

  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 travel and / or the object X3a indicating that the user is away from the guidance route. Good. For example, the display control unit 116 may display the object X1a indicating the direction in which the user should travel regardless of the direction in which the user is facing.
