<Embodiment>
[Configuration example of navigation system]
FIG. 1 shows an overall configuration example of a navigation system including the navigation device of this embodiment.
The navigation device of this embodiment is a mobile terminal 100 possessed by a user U who travels on a bicycle B. FIG. In other words, the mobile terminal 100 as the navigation device of the present embodiment performs navigation (guidance) to the destination when the user U travels to the destination on the bicycle B. FIG.
Application software (navigation application) for realizing the navigation function of the present embodiment is installed in the mobile terminal 100 . The mobile terminal 100 of this embodiment may be, for example, a smart phone, a tablet terminal, or the like owned by the user. Note that the mobile terminal 100 may be configured as a dedicated device specialized for the navigation function of this embodiment. In the following description, a case where mobile terminal 100 is a smart phone possessed by user U will be taken as an example.

The mobile terminal 100 is held by a holder or the like on the handlebar of the bicycle B, for example. Thereby, the user U can see the navigation screen displayed on the display surface of the mobile terminal 100 when riding the bicycle B, for example.

Mobile terminal 100 is communicatively connected to map server 200 . The mobile terminal 100 acquires map information from the map server 200 for navigation. The mobile terminal 100 uses the acquired map information to perform navigation. Note that map information may be stored in mobile terminal 100 in advance instead of acquiring map information from map server 200 .

[Navigation screen display on mobile terminal]
An example of an operation procedure of the mobile terminal 100 as the navigation device of the present embodiment and an example of a navigation screen displayed on the mobile terminal 100 will be described below with reference to FIGS. 2 to 7. FIG. In the following description, the display unit of the mobile terminal 100 is assumed to be a touch panel, and the screen displayed on the display unit can be tapped or swiped by an operating body such as a finger. For example.

When using the navigation function of the mobile terminal 100, the user U operates the mobile terminal 100 to activate a navigation application. An application screen of the activated navigation application is displayed on the display unit of the mobile terminal 100 .
When the user U activates the navigation application, the user U first performs a route setting operation. For this purpose, the user performs an operation to display the departure point/destination setting screen.

FIG. 2A shows an example of a departure point/destination setting screen, which is one of the route setting screens displayed according to the user U's operation. A map area AR11 and an operation panel area AR12 are arranged on the departure point/destination setting screen in FIG.
In the map area AR11, the route set according to the operation for setting the departure point/destination is displayed. The operation panel area AR12 is an area where route setting operations are performed. In the operation panel area AR12, a departure point setting area AR121, a destination setting area AR122, a waypoint setting button BT11, and a navigation execution button BT12 are arranged.

The departure point setting area AR121 is an area where an operation for setting a departure point is performed. The departure point is set by the user U performing an operation of inputting the departure point in the departure point setting area AR121 (departure point input operation).
The destination setting area AR122 is an area where an operation to set a destination (final target point) is performed. The destination is set by the user U performing an operation (destination input operation) of inputting the destination in the destination setting area AR122.
The user U may input the information of registered points such as the current location, home, workplace, etc. as the starting point or destination, or may input the name of a store, building, sightseeing spot, or the like. , you may enter the street address. The input of the starting point or the destination may be a character input, or an operation of designating a point as the starting point or the destination in the map area AR11.

The set departure point and destination are reflected in the map area AR11. That is, as shown in the figure, a departure point mark Mst indicating the set departure point and a destination mark Mgl indicating the set destination are arranged on the map in the map area AR11. Further, a route marking line Lrt is arranged as a straight line connecting the departure point mark Mst and the destination mark Mgl.

In this embodiment, in addition to the starting point and the destination, a waypoint (an example of an intermediate target point) can also be set. A waypoint is a point through which the user passes through from the departure point to the destination. The waypoints include, for example, points such as bridges and railroad crossings that must be passed to reach the destination. Also, the waypoints may include shops, buildings, sightseeing spots, etc. that the user U wants to stop by for a break or sightseeing.

When trying to set a waypoint from the state of FIG. 2A, the user U performs an operation (tap operation) on the waypoint setting button BT11. In response to the operation of the waypoint setting button BT11, the waypoint setting screen shown in FIG. 2B is displayed as another route setting screen. The waypoint setting screen is a screen on which the user U performs an operation of inputting a waypoint (a waypoint input operation).

Under the initial state in which the departure point/destination setting screen in the state of FIG. 2A is transitioned to the waypoint setting screen in FIG. are connected by the route marking line Lrt.

In addition, a handle HD for setting waypoints is arranged on the route marking line Lrt.
As an operation on the map area AR11, the user U first performs a tap operation on the displayed handle HD. In response to the tap operation, the handle HD changes to display a pin as the waypoint mark Mwp. The user U performs an operation of dragging the displayed waypoint mark Mwp to a position on the map that the user wants to set as a waypoint. Then, the position on the map when the drag operation is released is determined as the waypoint.
Alternatively, as an operation for the map area AR11, the user U may move the handle HD to a position on the map that the user wants to set as a waypoint. The route marking line Lrt changes so as to follow the movement of the steering wheel HD. When the user U moves the handle HD to a position on the map that he or she wants to set as a waypoint, the user U performs an operation for confirming the waypoint (a waypoint confirmation operation). The waypoint confirmation operation may be a tap operation on the steering wheel HD. The handle HD determined as the waypoint changes to a waypoint mark Mwp indicating the waypoint.

When the transit point mark Mwp indicating the transit point determined by the above operation is displayed, the route marking line Lrt between the point (departure point or transit point) immediately before the transit point mark Mwp is displayed. A new handle HD is arranged in the middle and in the middle of the route marking line Lrt between the point (destination or waypoint) next to the waypoint mark Mwp. The user U can further set waypoints by operating the newly arranged handle HD.
The waypoint setting screen of FIG. 2B shows an example in which three waypoint marks Mwp are sequentially arranged with the departure point as a base point as a result of the user U's operation for setting waypoints.

It should be noted that an operation of returning to the departure point/destination setting screen of FIG. 2(A) from the state of FIG. 2(B) and resetting the departure point and destination may be enabled.

A navigation execution button BT12 is arranged in the map area AR11 of the waypoint setting screen. After finishing setting the waypoint, the user U operates the navigation execution button BT12.
When the navigation execution button BT12 is operated, the mobile terminal 100 determines the route based on the departure point, destination, and waypoints that have been set so far. Then, the mobile terminal 100 changes the display to a navigation screen for navigating the determined route on the display unit.

A navigation execution button BT12 is also arranged in the departure point setting area AR121 of the departure point/destination setting screen in FIG. 2(A). That is, if the departure point and the destination are set, the user U operates the navigation execution button BT12 arranged in the departure point setting area AR121 of the departure point/destination setting screen without setting the waypoint. be able to. In this case, after the route based only on the departure point and the destination is fixed, the display transitions to the navigation screen.

Next, the navigation screen will be explained. FIG. 3A shows an example of a navigation screen. The navigation screen is a screen having a function of guiding a target point (destination, waypoint) corresponding to the determined route.
A progress area AR21, a direction/distance display area AR22, and a menu button BT20 are arranged on the navigation screen of FIG.

The progress area AR21 is an area showing how far the user U has progressed on the fixed route. Specifically, a progress bar is arranged in the progress area AR21, and dots are arranged on the progress bar as set target points (starting point (START), waypoint (SPOT), and destination (GOAL)). Then, a bicycle icon is arranged at the position of the progress bar corresponding to the current position of the user U. The left side of the position where the bicycle icon is arranged in the progress bar is colored in a predetermined color. The change indicates that the user has passed through.In addition, in the center of the route line in the left-right direction, there is a dot indicating the target point to which the user U is headed ("SPOT4" in the figure). ) is displayed in a state of being emphasized more than the dots of the other target points.
The target target point is a target point to be reached next by the user U from the relationship with the user U's current position among the target points (route points or destinations) set on the set route.
Also, the display of "42%" in the progress area AR21 is the route progress rate. The route progress rate indicates how far the user U has traveled on the route by the ratio of the distance traveled by the user U to the route.
Depending on the display of the progress area AR21 as described above, it is possible to visually grasp how far the user U has traveled on the route and which of the target points is the target point.

The direction/distance display area AR22 is an area in which the direction and distance corresponding to the target point (that is, the direction from the current position of the user U to the target point and the distance from the current position of the user U to the target position) are displayed. The distance from the current position of the user U to the target position may be a linear distance between the current position of the user U and the target point. Note that the distance from the current position of the user U to the target position may be the distance when the mobile terminal 100 calculates one appropriate route through route calculation and traces the calculated route. Specifically, in the direction/distance display area AR22 in the same figure, the direction/distance corresponding to the target target point and the distance corresponding to the destination (final target point) are displayed as follows.

A direction indication area AR221 is arranged in the direction/distance display area AR22 in FIG. The direction indication area AR221 is circular, and the center of the circle corresponds to the user U's current position. A straight line extending directly upward from the center of the direction indicating area AR221 is a traveling direction indicating line GD. The traveling direction indication line GD indicates the traveling direction of the user U. As shown in FIG.

A direction indication zone Zdi (an example of a first direction indication) is displayed in the direction indication area AR221. The direction indicating zone Zdi indicates the direction of the target target point with respect to the user U's current position and traveling direction. The direction indicating zone Zdi is, as shown in FIG. That is, the direction indicating zone Zdi indicates an approximate direction to the target point of interest rather than an exact direction. The direction indication zone Zdi may be formed, for example, as a sector that is symmetrical with respect to exactly one direction.

Since the user U is traveling on the bicycle B, there is a desire to enjoy and carefree riding until reaching the target destination point, for example, by choosing a road to go through depending on the mood or idea at that time. be. In such a case, if only one correct direction to the target target point is indicated on the navigation screen, the user U may find it difficult to go in a direction deviating from the indicated direction. It becomes difficult for the user U to act freely.
Therefore, if an approximate direction is indicated as in the direction indication zone Zdi of the present embodiment, the desire of the user U to freely select a road and go to the destination is not hindered, but rather positively. I can answer.
In this manner, the display of the navigation screen of the present embodiment enables appropriate navigation to the destination in response to the case where the user heads for the destination while deciding the route at will.

Further, on the outermost circumference of the direction indication area AR221, a dot-like mark (an example of a second direction indication) is arranged as the destination pointer Ptr. The destination pointer Ptr indicates the direction of the destination with respect to the current position of the user U and the traveling direction. The direction of the destination indicated by such a destination pointer Ptr indicates an accurate direction, unlike the direction indicating zone Zdi that indicates the approximate direction of the target target point.
For example, when the target point is a point that must be passed through, such as a bridge or a railroad crossing, there may be no choice but to take a somewhat detour route. In such a case, for example, the direction indicating zone Zdi may indicate a direction substantially opposite to the direction to the destination. In such a case, for example, if only the direction to the target target point is indicated without indicating the direction to the destination, the user U can grasp the relationship between the direction to the target target point and the direction to the destination. You may not be able to and feel insecure.
Therefore, in this embodiment, the direction to the target target point and the direction to the destination are presented to the user U at the same time by displaying the destination pointer Ptr together with the direction indication zone Zdi. As a result, in the present embodiment, the user U can grasp the relationship between the direction to the target target point and the direction to the destination at any time, and the above anxiety can be eliminated.

A distance numerical value area AR222 is arranged in the direction/distance display area AR22. A distance numerical value area AR222 in the figure is an area that numerically indicates the distance from the current position to the target target point.
Although the figure shows an example in which the distance numerical value area AR222 is arranged near the center of the direction indication area AR221, the position in the navigation screen where the distance numerical value area AR222 is arranged is not particularly limited.

Note that the form of the navigation screen is not limited to the example shown in FIG. As an example, the direction indicating area AR221 may be elliptical or rectangular instead of circular.

Changes in the display of the navigation screen according to the distance to the target target point will be described with reference to FIGS. 3A, 3B, and 3C.
The navigation screen of FIG. 3A corresponds to the case where the distance to the target target point is within a predetermined range defined as "long distance". On the other hand, in the navigation screen of FIG. 3B, since the user U has advanced the route more than in the case of FIG. It corresponds when it is within the range. In the navigation screen of FIG. 3(C), the distance to the target target point is within the predetermined range defined as "short distance" because the user U has progressed further along the route than in the case of FIG. 3(B). Responsive when you are.
As the distance to the target target point changes as described above, the distance to the destination also changes. In the order of 3(C), the object target point as a waypoint indicated by "SPOT4" is approached. In addition, the numerical value of the route progress rate in the progress area AR21 also changes so as to increase in the order of FIGS. 3(A), 3(B), and 3(C).

The direction indicating zone Zdi in FIG. 3A, which corresponds to the case where the distance to the target target point is "long distance", is fan-shaped with a predetermined central angle (long-distance corresponding central angle). Next, the direction indicating zone Zdi in FIG. 3B corresponding to when the distance to the target target point is "middle distance" is set to a predetermined center angle smaller than the long-distance center angle (medium-range center angle). angle). Next, the direction indicating zone Zdi in FIG. 3(C) corresponding to when the distance to the target target point is "short distance" has a predetermined central angle smaller than the central angle corresponding to the middle distance (center angle).
Thus, the central angle of the direction indication zone Zdi changes according to the distance to the target point of interest.

The color of the direction indicating zone Zdi also changes differently depending on the distance to the target point.
For example, the direction indicating zone Zdi in FIG. 3A corresponding to when the distance to the target target point is "long distance" is displayed in green. Next, the direction indicating zone Zdi in FIG. 3(B) corresponding to when the distance to the target target point is "middle distance" is displayed in yellow. Next, the direction indicating zone Zdi in FIG. 3(C) corresponding to when the distance to the target target point is "short distance" is displayed in red.

In this way, the direction indication zone Zdi is made to vary in fan-shaped center angle and color depending on the distance to the target point of interest. As a result, the user U can grasp the approximate direction of the target target point and the approximate distance to the target target point simply by paying attention to the direction indication zone Zdi on the navigation screen.

In addition, in the progress bar of the progress area AR21 in FIG. 3, the portion to the left of the bicycle icon corresponding to the passed route portion is displayed in the same color as the direction indication zone Zdi according to the distance to the target target point. This makes it easier to grasp the approximate distance to the target target point when focusing on the progress area AR21.

Next, with reference to FIG. 4, an example of the display mode of the navigation screen when the current position is approaching the target target point will be described.
FIG. 4A shows an example of the navigation screen when the distance to the target target point is within a predetermined state (point approaching state) where the target target point will be reached soon. .
In response to the point approaching state, an approach notification area AR41 is displayed on the navigation screen. In the approach notification area AR41, a message is displayed to notify the user U that the target target point has been approached, such as "Arrived near SPOT4".

As the user U further travels toward the target target point from the point approaching state shown in FIG. In the state within (arrival state), an arrival notification area AR42 is displayed as shown in FIG. 4B instead of the approach notification area AR41. In the arrival notification area AR42, a message is displayed that notifies the user U that the vehicle has arrived at the target target point, such as "Thank you for your hard work! You have arrived near your destination."

When the target point is the destination and the arrival state is reached, an end button BT31 and a return navigation button BT32 are arranged on the navigation screen as shown in FIG. 4(B).
The end button BT31 is a button operated when the navigation may be ended.
The return route navigation button BT32 is a button that is operated when the user U returns to the starting point on the outward route via the same route that was set at the time of departure. When the return navigation button BT32 is operated, the mobile terminal 100 sets a route with the current position as the new departure point and the departure point of the outward trip as the new destination, and displays the navigation screen according to the set route. display.
Although not shown, for example, instead of the return navigation button BT32, or in addition to the end button BT31 and the return navigation button BT32, a destination confirmation button may be arranged. The destination confirmation button is a button operated by the user U when he/she wants to confirm the destination that has been reached this time on the map. When the destination confirmation button is operated, for example, the display transitions to a map screen in which the point as the destination is specified in a predetermined manner.

Next, menu operations on the navigation screen will be described. As shown in FIGS. 4 and 5, etc., a menu button BT20 is arranged on the navigation screen in states other than the arrival state corresponding to the destination.
When the menu button is operated, a menu area AR23 is arranged on the navigation screen as shown in FIG. 5(A).
Buttons corresponding to predetermined menu items are arranged in the menu area AR23. Specifically, a map display button BT21, a return button BT22, and an end button BT23 are arranged in the menu area AR23 of FIG.

The map display button BT21 is a button for instructing display of a map-aided navigation screen. The navigation screens of the present embodiment shown in FIGS. 4, 5, etc., do not present information such as the user U's current position, target point, distance, etc. on a map. However, while the user U is on the way to the target point, depending on the situation, the user U may want to check the azimuth relationship, distance, etc. between the user's current position and the target point on the map. In such a case, the user U can operate the map display button BT21 to display the map-aided navigation screen.

FIG. 5B shows an example of the map-aided navigation screen displayed in response to the operation of the map display button BT21.
In the map-aided navigation screen of FIG. 1, a map is displayed on which a current position mark Mpt and target point marks Mwy1 and Mwy2 are arranged. The current position mark Mpt is displayed in a state in which it is connected to the target point mark Mwy (Mwy1, Mwy2) by a straight route marking line Lrt in order according to the route.
The map on the map-aided navigation screen can be enlarged or reduced by operating the enlargement button BT41-1 or the reduction button BT41-2.

In the map-aided navigation screen as well, a direction indication zone Zdi indicating the direction from the current position to the destination is displayed with the current position mark Mpt as a reference, as in the navigation screen. Further, the distance numerical value area AR40 arranged on the map-aided navigation screen indicates the distance from the current position of the user U to the target target point by numerical values.
Also, the color of the direction indication zone Zdi on the map-aided navigation screen changes according to the distance from the current position of the user U to the target target point, as in the case of the navigation screen.
Also, the current position mark Mpt, the target point mark Mwy, and the route marking line Lrt may be displayed in the same color as the direction indication zone Zdi according to the distance from the current position of the user U to the target target point.
The return button BT42 is a button that is operated to return to the navigation screen. When the return button BT42 is operated, the navigation screen shown in FIG. 3 may be displayed. Alternatively, when the return button BT42 is operated, the navigation screen shown in FIG. 5A may be displayed.

The navigation screens of FIGS. 3 and 4 show the direction and distance corresponding to the target target point that the user U should reach next. The mobile terminal 100 of the present embodiment can also display a navigation screen presenting directions and distances corresponding to target points (unreached target points) ahead of the target target point on the route. The mobile terminal 100 of the present embodiment can also display a navigation screen presenting the direction and distance corresponding to the current position of the target point that the user U has already passed through on the route (already passed through target point).
This point will be described with reference to FIGS. 6A and 6B, taking as an example a navigation screen for presenting an unattained target point.

In addition, the direction/distance display area AR22 on the navigation screen of the present embodiment can be swiped in the horizontal direction. A leftward swipe operation on the direction/distance display area AR22 is an operation for displaying a navigation screen corresponding to the unattained target point. A swipe operation to the right on the direction/distance display area AR22 is an operation for displaying a navigation screen corresponding to the routed target point on the route.

FIG. 6A shows the navigation when the direction and distance display area AR22 is swiped to the left as indicated by the arrow Y1 in a state where the direction and distance of the target target point are presented. showing the screen. In the figure, a case where the target target point is "SPOT1" (indicated by progress area AR21) is taken as an example.

By performing the leftward swipe operation as described above, in the direction/distance display area AR22, the direction indication area AR221 (including the distance numerical value area AR222) presenting the direction and distance to the target target point is changed to Move to the left and out of the display range of the navigation screen. Instead, in the direction/distance display area AR22, a direction indication area AR221 presenting the direction and distance of the unattained target point as "SPOT2", which is one ahead of the target target point from the right direction, moves leftward. It appears as if it were coming.

FIG. 6B shows a state in which a direction indication area AR221 presenting the direction and distance of an unattained target point as "SPOT2" is displayed in the direction/distance display area AR22 in response to a leftward swipe operation. is shown. In other words, the direction indication area AR221 in FIG. 13 indicates the direction and distance from the current position of the user U to the unattained target point as "SPOT2", and the direction indication zone Zdi, the distance numerical value area AR222, and the like are displayed. done.
As shown in the figure, in the distance numerical value area AR222 which presents the direction and distance of a target point other than the target target point, the direction indicating zone Zdi has a central angle corresponding to the distance to the unattained target point. It has a central angle, but is colored, for example, gray, and colors other than green, yellow, and red to indicate that directions for target points other than the target target point are presented. you can

Further, when the menu button BT20 on the navigation screen displaying the direction/distance display area AR22 presenting the direction and distance of the unattained target point is operated as shown in FIG. The menu area AR23 is displayed as follows.
In the menu area AR23 of FIG. 7A, in addition to a map display button BT21, a return button BT22, and an end button BT23, an unattained target point specification button BT24 is arranged.

The unattained target point designation button BT24 is a button for performing an operation for canceling the previous target point and designating the unattained target point as a new target point.
When the user U operates the unattained target point designation button BT24 in the state shown in FIG. 7A, the display transitions to the navigation screen shown in FIG. 7B.
The navigation screen of FIG. 7B reflects the result of designating "SPOT2" as the new target point. That is, in the progress area AR21, a progress bar is displayed with the target point set to "SPOT2". In the direction/distance display area AR22, the direction and distance corresponding to the target target point as "SPOT2" corresponding to the current position of the user U are displayed. Further, the direction indication zone Zdi in this case is displayed with a central angle and a color according to the distance from the current position of the user U to "SPOT2".

Also, in the navigation screen of FIG. 7B, a confirmation dialog area AR30 is arranged. The confirmation dialog area AR30 is a dialog for confirming with the user U whether or not "SPOT2" may be set as the target target point.
When the user U may set "SPOT2" as the target target point, the user U does not have to perform a confirmation operation, for example. In this case, the confirmation dialog area AR30 is erased after a certain period of time has elapsed since the display was started, and "SPOT2" is set as the target target point in response to the erasure being pointed.
On the other hand, for example, if the unattained target point specification button BT24 is erroneously operated, or if "SPOT2" is to be stopped from being set as the target target point, the user U cancels the confirmation dialog area. A tap operation is performed on the area displayed as "Cancel" on the AR30.
When such a cancel operation is performed, for example, the display may return to the navigation screen with the original "SPOT1" as the target target point. Alternatively, when a cancel operation is performed, a navigation screen showing the direction and distance corresponding to "SPOT2", which is undetermined as the target point as shown in FIG. 6B or FIG. 7A, is displayed. May be made to return.
