The server device 10 includes a current location information acquisition unit 111, a route search unit 112, and a database 120 as main functional configurations. For example, the CPU 11a executes a predetermined program stored in the memory 11b or the like and cooperates with the hardware of the server device 10 to realize each functional configuration illustrated in FIG. Details of each functional configuration will be described below.

  The database 120 stores various types of information such as information necessary for processing executed in the server device 10 and information generated by the processing. The database 120 stores, for example, map information, facility information, and guidance point information.

  The map information includes road information, railway line information, building information, terrain information, address information, and other geographical information. The facility information includes information about facilities such as convenience stores, cafes, stations, fast food, restaurants, buildings (buildings), and the like. The facility information includes information on products and / or services handled at the facility. Furthermore, the facility information includes information on the position of each facility associated with the map information. The facility information may be information included in the map information. The guidance point information is information presented to the user during route guidance (navigation) via the wristwatch-type device 20 or the portable terminal 30 and the like, and information on an object that can be a landmark on the route and / or a location change position. It is. The guide point information includes, for example, an intersection, a pedestrian crossing, and a pedestrian bridge.

  The current location information acquisition unit 111 acquires the current location information of the user wearing the wristwatch type device 20 and carrying the portable terminal 30 from the portable terminal 30 (or from the portable terminal 30 via the wristwatch type device 20). Note that the current location information of the user is positioning information obtained based on the positioning process of the positioning unit 36 of the portable terminal 30 (if the wristwatch type device 20 has a positioning function, the wristwatch type device 20 In this case, the user may wear the wristwatch type device 20 and may not carry the portable terminal 30. The same applies to the following description.) .

  The route search unit 112 receives information on route search conditions (for example, departure place, destination, moving means) from an external device such as the wristwatch-type device 20, and performs route search processing based on the information. Information about the searched route is transmitted to the wristwatch type device 20. The information about the searched route includes map information, facility information, and guidance point information. The route searching process can be performed for each moving means (for example, walking route searching and car route searching can be performed). Further, the route search process can be performed by an arbitrary method, and in the present embodiment, it is performed by a well-known method, and detailed description thereof is omitted.

  With reference to FIG. 3, the example of a function structure of the wristwatch-type device 20 which concerns on one Embodiment is demonstrated. The wristwatch type device 20 includes a current location information acquisition unit 211, a route search unit 212, and a display control unit 213 as main functional configurations. The wristwatch type device 20 implements each functional configuration by, for example, the CPU 21a executing a predetermined program stored in the memory 21b or the like to cooperate with the hardware of the wristwatch type device 20. Details of each functional configuration will be described below.

  The current location information acquisition unit 211 acquires the current location information of the user specified by the mobile terminal 30 from the mobile terminal 30. The acquired current location information is transmitted to the server device 10. Note that the current location information is acquired from the mobile terminal 30, but the present location information is not limited to this, and the current location information may be specified by the wristwatch-type device 20 including a positioning processing unit and performing positioning processing.

  The route search unit 212 acquires information on route search conditions (for example, departure place, destination, moving means) necessary for performing route search processing, and transmits the information to the server device 10. For example, the route search unit 212 can acquire the current location information of the user wearing the wristwatch device 20 as the departure location information in the route search via the current location information acquisition unit 211. Further, the route search unit 212 can acquire information input via the operation unit 24 of the wristwatch type device 20 as information on a destination and moving means in the route search. In addition, the route search unit 212 acquires information on a route search result corresponding to the transmitted route search condition information from the server device 10. In the present embodiment, the route search process is performed by the server device 10, but the present invention is not limited to this method, and the route search process may be performed by the wristwatch type device 20.

  The display control unit 213 controls the display unit 25 to display various types of information such as time information, information on processing results by the wristwatch type device 20, and information received from an external device. Further, while the navigation function is being executed in the wristwatch-type device 20, the display control unit 213 displays the current location information of the user acquired by the current location information acquisition unit 211 and the route search result acquired by the route search unit 212. Based on this, the display unit 25 is controlled to display information for navigating the user from the current location to the destination along the route.

  Moreover, in this embodiment, the wristwatch-type device 20 can perform navigation to the destination in a plurality of different modes for the user. The display control unit 213 performs control so that a navigation screen corresponding to each navigation mode is displayed on the display unit 25 in a switchable manner.

  In particular, in the present embodiment, the navigation screen corresponding to the navigation mode preferably includes a screen for navigating so that the user can intuitively reach the destination with a simple display. That is, since the wristwatch type device 20 has the shape and size of a wristwatch, the size of the display unit 25 is limited compared to the display unit of a portable terminal such as a tablet terminal or a smartphone. Therefore, it is more convenient for the user to display a navigating screen on the display unit 25 so that the user can grasp how to reach the destination intuitively than a rich screen with a large amount of information. .

  The navigation mode includes, for example, the following first mode navigation and second mode navigation. The navigation in the first mode is navigation based on the relative positional relationship between the user's current location and the destination. The second mode of navigation is navigation based on the route to the destination.

  In the first mode, a navigation screen showing the relative positional relationship between the current location and the destination is displayed without showing the route from the current location to the destination of the user.

  The second mode displays a navigation screen indicating whether the user is on the route to the destination without showing the route corresponding to the direction. In the navigation screen in the second mode, the traveling direction on the route to the destination is indicated so as to face a predetermined position on the display unit 25 regardless of the direction and the direction of the display unit 25. It is. Further, the navigation screen in the second mode shows the relative direction of the direction of the user (display unit 25) with respect to the traveling direction. Note that the navigation modes that can be implemented by the wristwatch type device 20 are not limited to these, and can include arbitrary modes.

<Example of navigation mode>
A specific example of the navigation screen in the first mode and the second mode displayed under the control of the display control unit 213 will be described below.

(1) Example 1 of the first mode
An example of navigation screen (arrow navigation screen) in the first mode will be described with reference to FIG. In this example, on the navigation screen displayed on the display unit 25 of the wristwatch type device 20, the direction of the destination starting from the current location is indicated by an arrow 41 as the relative positional relationship between the current location of the user and the destination. It is shown. In addition, no map or route is shown on the navigation screen. In this way, even if it is a simple screen that does not show the route to the destination, the direction of the destination starting from the current location is shown on the screen, so that the user can intuitively select the route and follow the destination. Can arrive.

  In the example shown in FIG. 4, the name of the destination (“Convenience Store A”) is shown at the top of the navigation screen, and the distance (“166 m”) from the current location to the destination is shown at the bottom. .

(2) Example 2 of the first mode
With reference to FIG. 5, another example of the navigation screen (radar navigation screen) in the first mode will be described. In this example, the navigation screen displayed on the display unit 25 displays an icon (image) 51 indicating the current location and an icon 52 indicating the destination in order to indicate the relative positional relationship between the current location and the destination of the user. Is shown on one screen. The distance from the user's current location to the destination is indicated by the positional relationship between the icon 51 indicating the current location and the icon 52 indicating the destination displayed on one screen. In particular, in this example, in the form of a radar chart, a current location icon 51 is shown at the center of the screen, and a destination icon 52 is shown at a position corresponding to the distance and direction of the destination from the current location. . Also, a plurality of concentric circles with different distance radii centered on the icon 51 of the current location are shown. Each radius of the concentric circles can be set by an arbitrary method. For example, the radius can be set for every predetermined distance (for example, every 50 m), or the radius of one concentric circle can be set as the distance from the current location to the destination. In addition, no map or route is shown on the navigation screen.

  In this way, even on a simple screen where the route to the destination as shown in FIG. 5 is not shown, the destination icon is displayed on the screen at a position corresponding to the distance and direction of the destination from the current location. By displaying the ground icon on the screen, the user can reach the destination while intuitively selecting the route.

  As shown in FIG. 5, the distance from the current location to the destination (“166 m”) may be displayed on the screen, or an icon (for example, icon 53) indicating facilities existing around the current location is navigated. It may be displayed at a corresponding position on the screen. The shape and pattern of the icon indicating the facility may be set so that the type of the facility can be specified. Further, this navigation screen may be displayed in the north up or the head up. Further, the navigation screen may be displayed such that the destination icon 52 is shown in the upper center of the display unit 25.

(3) Example of Second Mode With reference to FIG. 6, an example of a navigation screen (turn-by-turn navigation screen) in the second mode will be described. In this example, the navigation screen displayed on the display unit 25 displays icons 61 and 62 indicating information on a course change (turn-by-turn) existing on the route from the current location to the destination, and the current location of the user. An icon 63 is displayed. In this embodiment, the course change is to change the course at a branch point on the route so as to proceed toward the destination according to the route search result. The course change in the present embodiment does not include a change in the traveling direction due to traveling along a curved path. The icon 61 indicates route change information for a left turn. The icon 62 indicates route change information for a right turn. The value shown on the right side of the icons 61 and 62 is the distance from the current location to the course change position. That is, in this example, in order to go to the destination, it is indicated that the user needs to make a right turn at a point 100 m from the current location and a left turn at a location 150 m from the current location. In addition, on the left side of the icons 61 and 62, the intersection names of the course change positions are respectively shown.

  In this example, the navigation screen shows the icons 61 and 62 indicating the course change and the line connecting these icons, but the user can grasp the direction (direction) that the user should travel to the destination. It does not show the path of a simple shape. That is, the route corresponding to the direction is not shown. For example, even if the shape of the actual route is curved, the route having the curved shape is not shown on the navigation screen in this example. Further, in this example, the icon 63 indicating the current location is displayed at a position on the extension line of the line connecting the icons 61 and 62 indicating the change of route, thereby indicating that the user is on the route to the destination. Has been. That is, whether or not the user is on the route to the destination is indicated by whether or not the icon 63 indicating the current location is displayed at a position on the extension line of the line connecting the icons 61 and 62 indicating the change of route. it can. The method for indicating whether or not the user is on the route to the destination is not limited to this method, and any method can be adopted. For example, in order to indicate that the user is off the route, the icon 63 indicating the current location may be displayed blinking or discolored, or a message indicating that the user is off the route may be displayed on the navigation screen. .

  In this example, an icon 63 indicating the current location is displayed at the bottom of the screen. In addition, icons 61 and 62 indicating a course change are displayed in a row in a row from the bottom to the top with an icon 63 indicating the current location in order from the current location. That is, the navigation screen of this example shows the traveling direction on the route for the user to travel toward the destination regardless of the direction and the direction of the display unit 25 (user) (that is, neither north-up nor head-up). Is always directed to the upper center on the display unit 25. In this example, the traveling direction on the route is directed to the upper center on the display unit 25. However, the present invention is not limited to this, and the lower center, the right center, the left center, You may set so that it may always face other predetermined parts, such as the part designated by the user. Thus, the navigation screen displayed on the display unit 25 realizes a user-friendly user interface by making the traveling direction on the route always face a predetermined part (for example, the upper part) on the display unit 25. Can do. For example, when the navigation screen has a scroll function, the navigation screen only scrolls in the vertical direction (coaxial direction), and sequentially displays icons indicating all the course changes existing from the current location to the destination. be able to.

  Note that the icon 63 indicating the current location may be displayed at the right end or the left end of the navigation screen, and the icon indicating the course change position may be displayed vertically arranged in a daisy chain from the current location toward the other end of the screen. At this time, the navigation screen displayed on the display unit 25 may be scrollable in the left-right direction.

  As described above, in the present embodiment, the display control unit 213 scrolls and displays the navigation screen only in the coaxial direction (that is, both or one of the two opposing directions, for example, the up-down direction or the left-right direction). Images that respectively indicate a plurality of route change positions can be displayed sequentially. This is an icon indicating a change of course to the destination even if the screen is scrolled only in the same direction (for example, only in the vertical direction or only in the horizontal direction) on the conventional navigation screen displayed in North Up or Head Up. This is more convenient than not being able to confirm all of the above.

  Further, as the route change information indicated by the icons 61 and 62, the information on the guide points included in the route search result information acquired by the route search unit 212 can be used. The course change information can include, for example, information on a position where the course is changed at an intersection, a pedestrian crossing, a pedestrian bridge, or the like. Further, as an icon indicating a pedestrian crossing and a pedestrian bridge, an icon having a shape and a pattern indicating a pedestrian crossing or a pedestrian bridge may be used instead of an icon indicating a right turn or a left turn as shown in FIG.

  In addition, an arrow 64 that is an image indicating the direction in which the user is facing is shown in the icon 63 indicating the current location. Here, the direction in which the user faces indicated by the arrow 64 is a relative direction with respect to the traveling direction on the route for traveling toward the destination. Therefore, in this example, when the user is facing in a direction parallel to the traveling direction on the route, the arrow 64 is displayed so as to face the upper center of the display unit 25. Further, when the user is facing the right side of the traveling direction on the route, the arrow 64 is displayed so as to face the right side of the upper center of the display unit 25. Since the arrow 64 indicates the direction that the user is facing in this way, the user can intuitively grasp whether or not the user is facing the traveling direction on the route for traveling toward the destination. Note that the direction in which the user is facing is detected by the sensor 27. In the present embodiment, the image indicating the direction in which the user is facing is indicated by the shape of the arrow. However, the present invention is not limited to this, and any shape that can indicate the direction can be employed.

  In addition, in the navigation screen (turn-by-turn navigation screen) in the second mode, the information about the facility existing at the position along the route for traveling toward the destination among the information about the facility (for example, Icon) may be displayed at a corresponding position on the navigation screen. The display of the navigation screen can be simplified by not displaying information about facilities that are not located along the route (that is, facilities that do not enter the user's field of view during movement).

  FIG. 7 shows an example in which an icon (image) indicating a facility existing at a position along the route for traveling toward the destination is displayed on the navigation screen in the second mode. In the drawing, an icon 72 indicating a facility (convenience store A) is shown on the left side of a line (image) connecting an icon 71 indicating a course change position and an icon 73 indicating a current location. This indicates that the convenience store A exists on the left side of the place along the route between the route change position indicated by the icon 71 and the current location. The shape and pattern of the icon indicating the facility may be set so that the type of the facility can be specified. It should be noted that by clicking the icon 71 or the like, the details of the facility indicated by the icon 71 (information on products sold at the convenience store A) may be displayed on the navigation screen.

  In addition, the display control unit 213 displays the icon indicating the current location as described with reference to FIGS. 6 and 7 between the current location of the user and the route change position on the route to the destination. It can be controlled to be invisible when the distance is within a predetermined value (for example, 20 m) and visualized when the distance exceeds the predetermined value. Since the information on the current location of the user positioned by the positioning unit 36 (for example, by the positioning unit 36) may cause a certain error, the display control unit 213 indicates the current location, for example, even though the user is not on the course change position. It may happen that the icon is displayed on the icon indicating the course change position. In order to prevent such a problem, it is effective to make the icon indicating the course change position visible or invisible according to the distance between the current location of the user and the course change position. The predetermined value of the distance can be set according to the accuracy of the positioning process of the user's current location (the positioning accuracy of the user's position). Further, the display control unit 213 changes the display of the icon indicating the course change position when the distance between the current location of the user and the course change position is within a predetermined value (for example, by changing the color, Or, it can be displayed blinking). Thereby, the user can grasp | ascertain that he is around the course change position.

<How to switch navigation mode>
As described above, the display control unit 213 performs control so that the navigation screen corresponding to each navigation mode is displayed on the display unit 25 in a switchable manner. For example, the display control unit 213 can perform control so that the screens illustrated in FIGS. 4, 5, and 6 are displayed on the display unit 25 in a switchable manner. Hereinafter, a switching control method when the display control unit 213 switches and displays a navigation screen corresponding to a certain navigation mode from another navigation screen will be described. The method described below is an example, and the navigation screen may be switched by another control method, or may be switched in accordance with an operation instruction from the user.

(A) Control in accordance with the distance between the current location and the destination The display control unit 213 displays between the current location of the user and the destination during display on the display unit 25 of the navigation screen in the second mode. When the distance falls within a predetermined value, the display screen can be switched to the first mode navigation screen and displayed. As a specific example, when the display control unit 213 displays the turn-by-turn navigation screen on the display unit 25, when the distance between the current location of the user and the destination is within 20 m, In addition to displaying “near the destination” on the display unit 25, the display screen can be switched to the arrow navigation screen for display.

  In general, when a user is aiming for a destination according to navigation, after reaching the destination, the direction of the destination is indicated rather than a specific turning angle (information on route change) for reaching the destination. In some cases, the person who has been able to understand can intuitively understand how to reach the destination. Therefore, according to the distance between the current location and the destination, the navigation mode display in the second mode in which the route change information is shown but the destination direction is not shown, and the destination direction is shown but the route is shown. It is convenient for the user that control is performed so as to switch the display of the navigation screen in the first mode in which no change information is shown.

  The displayed navigation screen can be changed by various methods according to the distance between the current location and the destination. For example, as the distance between the current location and the destination increases, the screen shown in FIG. 4 (arrow navigation screen) → the screen shown in FIG. 5 (radar navigation screen) → the screen shown in FIG. 6 at a predetermined distance threshold. The display can be switched to (turn-by-turn navigation screen). Further, as the distance between the current location and the destination becomes longer, the screen shown in FIG. 4 changes to the screen shown in FIG. 5 (or from the screen shown in FIG. 5 to the screen shown in FIG. 6 at a predetermined distance threshold). Or the screen shown in FIG. 4 to the screen shown in FIG. 6). Further, as the distance between the current location and the destination becomes shorter, the display screen can be switched in the direction opposite to the above at a predetermined distance threshold.

(B) Control when reroute processing fails When performing a process (reroute process) for searching again the route from the current location to the destination due to some reason such as the user deviating from the route to the destination during navigation. There is. If the reroute process fails during display of the second mode navigation screen on the display unit 25, the display control unit 213 can switch the display screen to the first mode navigation screen and display it. Note that examples of reroute processing failure include a case where the reroute search calculation itself fails, a case where the communication state is poor and a research request cannot be issued to the server device 10, or a search result cannot be received. is there.

  The navigation in the first mode can be carried out if there is information on the current location of the user and the location of the destination even if there is no route information to the destination. Therefore, when the route search result cannot be obtained from the server device 10 due to the failure of the reroute process, it is convenient for the user to control the navigation mode in this way.

  As described above, according to the present embodiment, the display control unit 213 performs a plurality of different navigations so that the user can intuitively reach the destination with a simple display. The screen can be displayed on the display unit 25 in a switchable manner.

  As described above, since the wristwatch type device 20 has the shape and size of a wristwatch, the size of the display unit 25 is limited compared to the display unit of a mobile terminal such as a tablet terminal or a smartphone. Therefore, it is more convenient for the user to display a navigation screen on the display unit 25 so that the user can reach the destination in a simple and intuitive manner than a rich screen with a large amount of information. In addition, since information required for the user or information that can be provided to the user differs depending on the situation, the navigation screen corresponding to each navigation mode is displayed on the display unit 25 in a switchable manner for the user. Convenience is high. For example, the display of the first mode navigation screen in which the direction of the destination is shown but the route change information is not shown, and the second mode navigation screen in which the direction change information is shown but the direction of the destination is not shown It is convenient for the user to display on the display unit 25 so that the display can be switched.

[Processing flow]
Next, with reference to FIG. 8, a flow of processing executed in the wristwatch type device 20 will be described. Each processing step included in the processing flow described below may add another step between the processing steps. Further, a step described as one step for convenience can be executed by being divided into a plurality of steps, while a step described as being divided into a plurality of steps for convenience can be grasped as one step. Note that details of the processing of each processing step have already been described, and are omitted here.

  First, in step S <b> 11, the control unit 21 acquires information on a route search result corresponding to a route search condition (e.g., departure place, destination, moving means) necessary for the route search process.

  In step S12, the control unit 21 controls the display unit 25 to display information for navigating the user from the current location to the destination along the route based on the route search result acquired in step S11. Here, the navigation screen displayed on the display unit 25 may be a screen in an arbitrary mode. For example, the navigation screen in the first mode or the navigation screen in the second mode is displayed.

  In step S13, the control unit 21 determines whether to switch the displayed navigation screen. For example, when receiving a switching operation instruction from the user, when the distance between the current location and the destination is within a predetermined value, or when the reroute process fails, the control unit 21 determines to perform switching. To do.

  When it is determined in step S13 that switching is to be performed, in step S14, the control unit 21 switches and displays the navigation screen. For example, when a switching operation instruction is received from the user, the display screen is switched to a navigation screen corresponding to the instruction. The navigation screen switching display that is displayed when the distance between the current location and the destination is within a predetermined value or when the reroute process has failed is as described above.

  As described above, according to the present embodiment, the wristwatch-type device 20 performs a plurality of different navigations so that the user can intuitively reach the destination with a simple display. The screen can be displayed on the display unit 25 in a switchable manner.

  In addition, since the wristwatch type device 20 has the shape and size of a wristwatch, the size of the display unit 25 is limited as compared with the display unit of a portable terminal such as a tablet terminal or a smartphone. Therefore, it is more convenient for the user to display a navigation screen on the display unit 25 so that the user can reach the destination in a simple and intuitive manner than a rich screen with a large amount of information. Moreover, since information required for the user or information that can be provided to the user differs depending on the situation, each navigation screen corresponding to a different navigation mode is displayed on the display unit 25 in a switchable manner. Convenience is high for.
