It is. The guidance point information includes, for example, an intersection, a pedestrian crossing, and a footbridge.

  The current location information acquisition unit 111 wears the wristwatch type device 20 and acquires current location information of the user carrying the portable terminal 30 from the portable terminal 30 (or from the portable terminal 30 via the wristwatch type device 20). The current location information of the user is positioning information obtained based on the positioning process of the positioning unit 36 of the mobile terminal 30 (if the wristwatch type device 20 has a positioning function, the wristwatch type device 20 The positioning information may be obtained as long as the user wears the wristwatch type device 20 and does not need to carry the portable terminal 30. The same applies to the following description. .

  The route search unit 112 receives information on conditions (for example, departure place, destination, moving means) of the route search from an external device such as the wristwatch type device 20, and performs a route search process based on the information. Information on the searched route is transmitted to the watch-like device 20. The information on the searched route includes map information, facility information and information on guidance points. In addition, the process of route search can be performed for each moving means (for example, route search for walking and route search for cars can be performed). Further, the process of route search can be performed by any method, and in the present embodiment, it is assumed to be performed by a known method, and the detailed description is omitted.

  An example of the functional configuration of the watch-type device 20 according to one embodiment will be described with reference to FIG. 3. 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 realizes 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. The details of each functional configuration will be described below.

  The current location information acquisition unit 211 acquires 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. Although the present location information is acquired from the portable terminal 30, the present invention is not limited to this, and the present 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 conditions (for example, departure place, destination, moving means) of the route search necessary for processing the route search, and transmits the information to the server device 10. For example, the route search unit 212 can obtain the information on the current location of the user wearing the wristwatch type device 20 as the information on the departure location in the route search via the current location information acquisition unit 211. In addition, the route search unit 212 can acquire information input via the operation unit 24 of the wristwatch type device 20 as information of a destination and a moving means in the route search. In addition, the route search unit 212 acquires, from the server device 10, information on a route search result according to the information on the transmitted condition of the route search. In the present embodiment, the route search process is performed by the server device 10. However, the present invention is not limited to this method, and the route search process may be performed in 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 of processing results by the wristwatch type device 20, and information received from an external device. In addition, while the navigation function is being executed in the wristwatch type device 20, the display control unit 213 may use the current location information of the user acquired by the current location information acquiring unit 211 and the route search result acquired by the route search unit 212. Based on the information, control is performed to display on the display unit 25 information for navigating the user from the current location to the destination along the route.

  Further, in the present embodiment, the wristwatch type device 20 can perform navigation to a destination in a plurality of different modes for the user. The display control unit 213 controls to display the navigation screen corresponding to each navigation mode on the display unit 25 in a switchable manner.

  In particular, in the present embodiment, it is preferable that the navigation screen corresponding to the navigation mode includes a simple display and a screen for navigation so that the user can intuitively reach the destination. 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 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 on the display unit 25 a screen for navigating so that the user can easily and intuitively understand how to reach the destination, rather than a rich screen with a large amount of information .

  The above-mentioned navigation modes include, for example, the navigation of the following first mode and the navigation of the second mode. The first mode of navigation is navigation based on the relative positional relationship between the current location of the user and the destination. The second mode of navigation is navigation based on the route to the destination.

  The first mode displays a navigation screen showing the relative positional relationship between the current location and the destination without indicating the route from the current location of the user to the destination.

  The second mode displays a navigation screen indicating whether the user is on a route to a destination without indicating a route corresponding to the direction. In addition, the navigation screen in the second mode shows that the traveling direction on the route for traveling toward the destination is directed to a predetermined position on the display unit 25 regardless of the direction and the orientation of the display unit 25. Be Furthermore, the navigation screen in the second mode shows the relative direction of the orientation of the user (display unit 25) with respect to the traveling direction. The navigation modes that can be implemented by the watch-type device 20 are not limited to these, and any mode can be included.

<Example of navigation mode>
Hereinafter, specific examples of the navigation screen in the first mode and the second mode displayed by the control of the display control unit 213 will be described.

(1) Example 1 of the first mode
An example of the 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 the arrow 41 as a relative positional relationship between the current location and the destination of the user. It is shown. Moreover, the map and the route are not shown on this navigation screen. As described above, even if the screen is a simple screen in which the route to the destination is not shown, the user can intuitively select the route and follow the destination by displaying the direction of the destination starting from the current location on the screen. You can arrive.

  Also, 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
Another example (a radar navigation screen) of the navigation screen in the first mode will be described with reference to FIG. In this example, the navigation screen displayed on the display unit 25 includes 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 of the user and the destination. Is shown on one screen. Further, the positional relationship between the icon 51 indicating the current position displayed on one screen and the icon 52 indicating the destination indicates the distance from the current position of the user to the destination. In particular, in this example, the icon 51 of the current location is shown at the center of the screen in the form of a radar chart, and the icon 52 of the destination is shown at a position according to the distance and direction of the destination from the current location. . Moreover, the map and the route are not shown on this navigation screen. The following two types of circles are shown on this navigation screen.

  The first circle is centered on a position corresponding to the user's current location, and has a radius corresponding to the distance from the current location to the user's destination, and is a circle that is enlarged or reduced according to the user's movement is there. The navigation screen shown in FIG. 5 shows a first circle c1 whose radius is the distance from the icon 51 indicating the position corresponding to the current position of the user to the icon 52 indicating the position corresponding to the destination. That is, the first circle has a radius obtained by reducing the actual distance from the current location to the destination at a predetermined scale. As a modification, the graphic based on the first circle may be displayed on the navigation screen shown in FIG. 5 instead of the first circle. The figure based on the first circle is a figure whose shape is determined based on the first circle, and for example, the inscribed rectangle of the first circle, the circumscribed rectangle of the first circle, or the first circle and the center Are common, and the circumference includes an ellipse or the like passing the icon 52. In the whole of the embodiment displaying the first circle described below, it is possible to display a figure based on the first circle instead of the first circle.

  Further, the second circle is a circle having a radius corresponding to the distance from the current position, which is centered on the position corresponding to the current position of the user. In addition, a plurality of second circles having different radii can be displayed on one navigation screen. The navigation screen shown in FIG. 5 shows a plurality of second circles (concentric circles) c2, c3, c4, c5 having radii of different distances. The second circle c2 has a radius corresponding to a distance of 20 m from the current location of the user. The second circle c3 has a radius corresponding to the distance 250 m from the current location of the user. The second circle c4 has a radius corresponding to the distance 500 m from the current location of the user. The second circle c5 has a radius corresponding to a distance 750 m from the current location of the user. That is, the second circle has a radius that reduces the actual distance from the current location by a predetermined scale.

  Thus, even on a simple screen where the route to the destination as shown in FIG. 5 is not shown, it is possible to position the icon according to the current location and the distance and direction of the destination from the current location on the screen. By displaying a ground icon on the screen, the user can intuitively select a route while arriving at a destination.

  In addition, on the navigation screen shown in FIG. 5, the distance (for example, "600 m") from the current position to the destination may be displayed, or the position on the screen corresponding to the position of the facility existing around the current position. You may display the icon (for example, icon 53) which shows a plant | facility. The shape and pattern of the icon indicating the facility may be set so as to be able to identify the type of the facility. Also, this navigation screen may be displayed in the north up or may be displayed in the head up. Also, the navigation screen may be displayed such that the icon 52 of the destination is shown in the upper center of the display unit 25.

(2-1) Enlargement or Reduction of the Second Circle Further, the display control unit 213 displays the first circle and the first circle displayed on the navigation screen shown in FIG. 5 according to the distance from the current position of the user to the destination. Control to change the size of 2 circles (enlarged or reduced) and display. The timing of changing the size of the first circle and the second circle is, for example, when the first circle overlaps the second circle (ie, the radius of the first circle is equal to the radius of the second circle When it comes to

  As a specific example, when the user moves toward the destination, the size of the first circle is reduced so that the first circle is one of a plurality of second circles. When overlapping (that is, when the radius of the first circle becomes equal to the radius of the second circle), the display control unit 213 displays the overlapping second circle on the outermost side in the navigation screen. At the same scale, the first circle and the overlapped second circle and the smaller second circle are controlled to be enlarged and displayed.

  The example will be described with reference to the navigation screen shown in FIG. When the first circle c1 and the second circle c4 having a radius corresponding to 500 m overlap because the distance between the current position of the user moving toward the destination and the destination is 500 m, The first circle c1 and the second circles c4, c3 and c2 are enlarged and displayed at a scale such that the second circle c4 is displayed on the outermost side in the navigation screen.

  FIG. 6 shows an example of the enlarged navigation screen. In FIG. 6, a first circle c1 and a second circle c4, c3, c2 are displayed, and a second circle c5 is not displayed. The first circle c1 is displayed overlapping with the second circle c4. The degree of expanding the circle is not limited to the above example, and can be set arbitrarily.

  An example of the reduced display is as follows. It is assumed that the first circle overlaps the outermost circle displayed as the user moves away from the destination. At this time, the display control unit 213 reduces and displays the first circle and the second circle at a scale at which the additional second circle can be displayed outside the overlapping second circle in the navigation screen. Can be controlled to

  That is, in the navigation screen shown in FIG. 6, it is assumed that the first circle c1 overlaps the second circle c4 displayed on the outermost side as the user moves in the direction away from the destination. At this time, the display control unit 213 controls to display the second circle c5 as shown in FIG. 5 and to reduce and display the second circles c4, c3 and c2. The first circle c1 is displayed overlapping with the second circle c4. The degree of reduction can be set arbitrarily and is not limited to the above.

  As described above, the effect of changing the sizes of the first circle and the second circle in accordance with the distance from the current location to the destination will be described. First, by increasing the size of the first circle and the second circle as the distance from the current location to the destination decreases, an icon indicating the facility when there is a facility between the current location and the destination ( Many facility icons can be displayed on the screen. For example, compared with the case where the maximum circle of the second circle is the circle corresponding to the radius 750 m, more facility icons are displayed when the maximum circle of the second circle is the circle corresponding to the radius 500 m It can be done.

  In addition, if the maximum circle of the second circle is fixed by a circle corresponding to a radius of 750 m, the navigation screen is displayed as the distance between the current position and the destination becomes shorter (for example, when it becomes about 50 m) The circumference of the first circle (ie, the circle that has a radius corresponding to the distance to the destination and displays an icon indicating the destination on the circumference) with respect to the size of is shortened. As a result, as the user approaches the destination, it becomes difficult for the user to grasp the exact direction of the destination. On the other hand, according to the present embodiment, the size of the first circle increases as the distance between the current location and the destination decreases, so that the direction of the destination is accurately grasped as the destination is approached. It becomes easy to do.

(2-2) Highlighted Display The display control unit 213 displays a second circle (in the example of FIG. 5, the first circle is displayed on the innermost side of the plurality of second circles (that is, the example shown in FIG. 5). When overlapping with the second circle c2), the overlapping second circle can be highlighted. The highlighting of the second circle is not limited when the first circle overlaps the smallest second circle, and when the radius of the first circle is within a predetermined value (for example, within 20 m). You can also By emphasizing and displaying the second circle in this manner, the user can intuitively understand that the user is near the destination. A method of emphasizing and displaying can be any method. For example, the second circle c2 can blink and be displayed, or the inside of the second circle c2 can be filled and displayed. The emphasizing method may adopt one method or a combination of plural methods.

(2-3) Switching of Navigation Mode The display control unit 213 causes the first circle to be displayed on the innermost side (i.e., the smallest) of the plurality of second circles (an example of FIG. 5). Then, when overlapping with the second circle c 2), another navigation screen can be displayed on the display unit 25. For example, when the first circle c1 in FIG. 5 overlaps the second circle c2, the display control unit 213 starts the navigation screen (turned on) shown in FIG. 7 from the navigation screen (the radar navigation screen) shown in FIG. Control can be performed to switch the display of the display unit 25 on the by-turn navigation screen). In addition, display switching to another navigation screen is not limited when the first circle overlaps the smallest second circle, and when the radius of the first circle is within a predetermined value (for example, within 20 m) It can be done.

(2-4) Other Display Control The display control unit 213 is far from the user's present position and the destination, and the present position and the purpose are such that the user's destination is not displayed on the navigation screen shown in FIG. 5. When the distance from the ground is far, it is possible to display the direction of the destination from the current location on the navigation screen, and not to display the icon 52 indicating the destination. For example, in the example of FIG. 5, when the distance from the current location to the destination is 2000 m, the icon 52 indicating the destination can not be displayed in the navigation screen. In such a case, the display control unit 213 can, for example, control to display an icon having a shape indicating the direction of the destination at an arbitrary position in the navigation screen.

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

  Furthermore, in this example, although the icons 61 and 62 indicating course change and the lines connecting these icons are shown on the navigation screen, it is possible to grasp the direction (direction) in which the user should move toward the destination Does not show a path of the same shape. That is, the path corresponding to the azimuth is not shown. For example, even if the shape of the actual path is curved, the navigation screen in this example does not show the path of the curved shape. Also, in this example, the icon 63 indicating the current position is displayed at a position on the extension of the line connecting the icons 61 and 62 indicating course change, thereby indicating that the user is on the route to the destination. It is done. That is, whether or not the user is on the route to the destination can be indicated by whether or not the icon 63 indicating the current position is displayed on the extension of the line connecting the icons 61 and 62 indicating course change. it can. The method of indicating whether the user is on the route to the destination is not limited to this method, and any method may be employed. For example, in order to indicate that the user has deviated from the route, the icon 63 indicating the current location may be displayed in a blinking or discolored manner, or a message indicating that the user has deviated from the route may be displayed on the navigation screen. .

  Also, in this example, an icon 63 indicating the current location is displayed at the bottom of the screen. Further, icons 61 and 62 indicating a course change are displayed vertically in a row and in an array with an icon 63 indicating the current position from the bottom to the top in order from the current position. That is, on the navigation screen of this example, regardless of the direction and the orientation of the display unit 25 (user) (that is, neither north-up nor head-up), the traveling direction on the route for the user to travel toward the destination Is shown to always face 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. The lower center on the display unit 25, the center on the right, the center on the left, It may be set to always face other predetermined parts, such as parts specified by the user. As described above, the navigation screen displayed on the display unit 25 realizes a user-friendly user interface by always setting the traveling direction on the route to a predetermined part (for example, the upper part) on the display unit 25. Can. For example, when the navigation screen has a scroll function, the navigation screen is sequentially scrolled in the vertical direction (coaxial direction) to sequentially display icons indicating each of the course changes existing from the current location to the destination. be able to.

  Alternatively, the icon 63 indicating the current position may be displayed at the right end or the left end of the navigation screen, and the icons indicating the course change position may be vertically arranged in a beaded array toward the other end of the screen in order from the current position. At this time, the navigation screen displayed on the display unit 25 may be scrolled horizontally.

  As described above, in the present embodiment, the display control unit 213 scrolls the navigation screen in the coaxial direction (that is, both or one of the two opposing directions, for example, up and down direction or left and right direction). It is possible to sequentially display images indicating a plurality of course change positions. This is an icon indicating the course change to the destination even if the screen is continued to scroll only in the same direction (for example, only in the vertical direction or only in the horizontal direction) on the conventional navigation screen displayed by north-up or head-up The convenience is high compared to the fact that you can not check all.

  In addition, as information on course change indicated by the icons 61 and 62, information on guidance points included in information on a route search result acquired by the route search unit 212 can be used. The information on course change can include, for example, information on the position at which the course is changed at an intersection, a pedestrian crossing, a footbridge, or the like. Further, as the icons indicating the pedestrian crossing and the footbridge, instead of the icons indicating right turn or left turning as shown in FIG. 7, icons of shapes and patterns indicating the pedestrian crossing or the footbridge may be used.

  Further, in the icon 63 indicating the current position, an arrow 64 which is an image indicating the direction in which the user is facing is shown. Here, the direction in which the user is pointing, which is 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 points in a direction parallel to the traveling direction on the route, the arrow 64 is displayed to point to the upper center of the display unit 25. In addition, when the user points in the direction to the right of the traveling direction on the route, the arrow 64 is displayed to point to the right than the upper center of the display unit 25. Since the arrow 64 indicates the direction in which the user is facing in this manner, the user can intuitively grasp whether or not the user is pointing in the traveling direction on the route for traveling toward the destination. The direction in which the user is facing is detected by the sensor 27. Moreover, in this embodiment, although the image which shows the direction which the user is pointing is shown by the shape of the arrow, it does not limit to this, arbitrary shapes which can show a direction are employable.

  In the navigation screen (turn-by-turn navigation screen) in the second mode, of the information about the facility, information about the facility existing at a position along the route for heading toward the destination (for example, The icon may be displayed at the corresponding position on the navigation screen. The display of the navigation screen can be simplified by not displaying the information about the facilities that exist at positions other than the position along the route (that is, facilities that do not enter the user's view during movement).

  FIG. 8 shows an example in which an icon (image) indicating a facility existing at a position along a path for advancing toward a destination is displayed on the navigation screen in the second mode. In the figure, 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 is present on the left side of the location along the route between the 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 as to be able to identify the type of the facility. In addition, by clicking the icon 71 or the like, details of the facility indicated by the icon 71 (such as information on products sold at the convenience store A) may be displayed on the navigation screen.

  Further, the display control unit 213 displays the display of the icon indicating the current position as described above with reference to FIGS. 7 and 8 between the current position of the user and the course 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 to be visualized when the distance exceeds the predetermined value. Since the information on the current location of the user located (for example, by the positioning unit 36) may cause a certain error, the display control unit 213 indicates, for example, the current location 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 position of the user and the course change position. The predetermined value of the above distance can be set according to the accuracy of the positioning process of the current position of the user (the positioning accuracy of the position of the user). Furthermore, the display control unit 213 changes the display of the icon indicating the course change position (for example, changing the color) when the distance between the current position of the user and the course change position falls within a predetermined value. Alternatively, it may blink and be displayed). Thereby, the user can grasp that he / she is around the course change position.

<How to switch navigation mode>
As described above, the display control unit 213 controls the display unit 25 to switchably display the navigation screen according to each navigation mode. For example, the display control unit 213 can perform control so as to switchably display the screens illustrated in FIGS. 4, 5, and 7 on the display unit 25. Hereinafter, a method of switching control when the display control unit 213 switches and displays one navigation screen to 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 according to an operation instruction by the user.

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

  Generally, when the user aims at a destination according to navigation, after reaching the vicinity of the destination, it indicates the direction of the destination rather than showing a specific turning angle etc. (course change information) for going to the destination If you do, you may be able to intuitively understand how to get to your destination. Therefore, according to the distance between the present location and the destination, the navigation screen display of the second mode in which the information on course change is shown but the direction of the destination is not shown, and the direction of the destination is shown It is convenient for the user to be controlled to switch between displaying the navigation screen of the first mode in which the information on the change is not 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 position and the destination becomes longer, the screen shown in FIG. 4 (arrow navigation screen) → the screen shown in FIG. The display can be switched to (Turn-by-Turn navigation screen). Also, as the distance between the current location and the destination becomes longer, from the screen shown in FIG. 4 to the screen shown in FIG. 5 (or from the screen shown in FIG. 5 to the screen shown in FIG. 7) Or from the screen shown in FIG. 4 to the screen shown in FIG. 7). In addition, as the distance between the current position and the destination becomes shorter, switching of the display screen can be performed in the opposite direction to the above at a threshold of a predetermined distance.

(B) Control when reroute processing fails When performing processing (reroute processing) in which a route from the current location to the destination is searched again during navigation for some reason such as the user departing from the route to the destination There is. The display control unit 213 can switch and display the display screen to the navigation screen of the first mode when the rerouting process fails while displaying the navigation screen of the second mode on the display unit 25. In addition, as an example of failure of the reroute process, when the calculation itself of the reroute search fails, when the communication state is bad, the research request can not be issued to the server device 10, or when the search result can not be received is there.

  The navigation in the first mode can be implemented as long as 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 can not be acquired from the server device 10 due to the failure of the reroute processing, it is convenient for the user to be controlled to switch the navigation mode in this manner.

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

  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 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 on the display unit 25 a screen for navigation so as to be able to reach the destination simply and intuitively, rather than a rich screen with a large amount of information. In addition, since the information required for the user or the information that can be provided to the user may differ depending on the situation, the navigation screen corresponding to each navigation mode may be displayed switchably on the display unit 25. Convenience is high. For example, the display of the navigation screen in the first mode in which the direction of the destination is indicated but the information on the course change is not shown, and the navigation screen in the second mode in which the information on the course change is shown but the direction of the destination is not shown It is highly convenient for the user to display on the display unit 25 in a switchable manner.

Processing flow
Next, with reference to FIG. 9, the flow of processing executed in the wristwatch type device 20 will be described. This process is realized, for example, in the wristwatch type device 20 by the CPU 11a executing a predetermined program stored in the storage unit such as the memory 11b and controlling each configuration of the wristwatch type device 20 and the like. Note that each processing step included in the processing flow described below may add another step between the processing steps. In addition, while the steps described as one step can be divided into a plurality of steps and executed for convenience, those described into a plurality of steps for convenience can be grasped as one step. The details of the processing of each processing step are omitted here because they have already been described.

  First, in step S11, the control unit 21 displays a radar navigation screen as shown in FIG. 5 on the display unit 25. As described above, the radar navigation screen displays a first circle or a figure based on the first circle, and a second circle. The first circle is centered on a position corresponding to the current location of the user, and has a radius associated with the distance from the current location of the user to the destination, and is a circle that is enlarged or reduced according to the movement of the user It is. The second circle is a circle centered on a position corresponding to the current location of the user and having a radius associated with the distance from the current location.

  In step S12, the control unit 21 controls to display the first circle in an enlarged or reduced size in accordance with the movement of the user.

  In step S13, the control unit 21 determines whether a predetermined condition is satisfied. For example, the control unit 21 determines whether the condition that the first circle overlaps the second circle (the radius of the first circle becomes equal to the radius of the second circle) is satisfied. If the condition is satisfied, the process proceeds to step S14.

  In step S14, the control unit 21 controls to change (enlarge or reduce) and display the size of the first circle and the second circle displayed on the radar navigation screen. For example, when the user moves toward the destination, the size of the first circle is reduced so that the first circle overlaps one of the plurality of second circles. The control unit 21 is configured such that the first circle and the overlapping second circle and a smaller second circle are scaled down so that the overlapping second circle is displayed on the outermost side in the navigation screen. Control to enlarge and display. Further, it is assumed that the first circle overlaps the second circle displayed on the outermost side as the user moves away from the destination. At this time, the control unit 21 reduces and displays the first circle and the second circle at a scale at which the additional second circle can be displayed outside the overlapping second circle in the navigation screen. Can be controlled.

  When it is determined in step S13 that the condition that the first circle overlaps the smallest second circle of the plurality of second circles is satisfied, in step S14, the control unit 21 determines that the overlapping is performed. The second circle can be emphasized and displayed.

  In step S15, the control unit 21 determines whether to end the display of the radar navigation screen. If the process does not end, the process proceeds to step S12. If the process ends, the flow of the process illustrated in FIG. 9 ends.

  As described above, according to the present embodiment, the sizes of the first circle and the second circle are changed according to the distance from the current location to the destination. As a result, for example, by increasing the sizes of the first circle and the second circle as the distance from the current location to the destination decreases, the facility is selected if the facility is between the current location and the destination. Many icons (facility icons) to be shown can be displayed on the screen.

  Also, for example, if the maximum circle of the second circle is fixed by a circle corresponding to a radius of 750 m, the distance between the current location and the destination becomes shorter. The circumference becomes short. As a result, as the user approaches the destination, it becomes difficult for the user to grasp the exact direction of the destination. On the other hand, according to the present embodiment, the size of the first circle increases as the distance between the current location and the destination decreases, so that the direction of the destination is accurately grasped as the destination is approached. It becomes easy to do.

  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 on the display unit 25 a screen for navigation so as to be able to reach the destination simply and intuitively, rather than a rich screen with a large amount of information. In addition, since the information required for the user or the information that can be provided to the user may differ depending on the situation, the navigation screens corresponding to the different navigation modes may be displayed switchably on the display unit 25. It is very convenient for
