Abstract

In a map display apparatus, a display processor causes a display to display a map based on map information. A priority object setting unit determines a priority object having higher priority than other objects contained in the map. A scroll processor scrolls the map displayed on the display in step with a scroll operation performed by a user. In a case where the priority object is located outside the map displayed on the display, the operating feel controller adds directivity to an operating feel imparted to the scroll operation in such a manner that a scroll operation for scrolling the map toward the priority object and a scroll operation for scrolling the map in any other direction arouse different operating feels.

Claims

1. A map display control device comprising:

a processor to execute a program; and

a memory to store the program which, when executed by the processor, performs processes of,

acquiring map information,

causing a touch panel to display a map based on said map information,

acquiring information on an operation performed on said touch panel by a user,

controlling a friction force or vibration imparted by said touch panel reactively to a touch by the user while performing the operation,

scrolling said map in step with a scroll operation performed by the user to scroll said map displayed on said touch panel,

determining a priority object having higher priority than other objects contained in said map, and

adding directivity to the imparted friction force or vibration in regard to said scroll operation in such a manner that, in a case where said priority object is located outside said map displayed on said touch panel, a scroll operation for scrolling said map toward said priority object and a scroll operation for scrolling said map in any other direction arouse different magnitudes of the imparted friction force or vibration.

2. The map display control device according to claim 1,

wherein said priority object has a continuous or intermittent elongated shape.

3. The map display control device according to claim 1,

wherein while the user performs said scroll operation, said processor causes the imparted friction force or vibration in regard to said scroll operation or the directivity added to the imparted friction force or vibration in regard to said scroll operation to change in magnitude in accordance with a predetermined rule.

4. The map display control device according to claim 3,

wherein said processor causes the imparted friction force or vibration in regard to said scroll operation or the directivity added to the imparted friction force or vibration in regard to said scroll operation to change in magnitude according to an amount of time elapsed from a start of said scroll operation.

5. The map display control device according to claim 3,

wherein said processor causes the imparted friction force or vibration in regard to said scroll operation or the directivity added to the imparted friction force or vibration in regard to said scroll operation to change in magnitude according to a distance between said map displayed on said touch panel and a position of said priority object.

6. The map display control device according to claim 3,

wherein said processor causes the imparted friction force or vibration in regard to said scroll operation or the directivity added to the imparted friction force or vibration in regard to said scroll operation to change in magnitude according to a speed at which said map is scrolled.

7. The map display control device according to claim 3,

wherein when a plurality of scroll operations are sequentially performed, said processor causes the imparted friction force or vibration, or the directivity added to the imparted friction force or vibration, to change in magnitude from one scroll operation to another.

8. The map display control device according to claim 1,

wherein said processor starts scrolling said map after a fixed period of time from when said scroll operation is started.

9. The map display control device according to claim 1,

wherein said processor adds directivity to the imparted friction force or vibration in regard to said scroll operation only with permission by the user.

10. The map display control device according to claim 1,

wherein said processor

causes said touch panel to display an operating feel control start icon preparatory to addition of directivity to the imparted friction force or vibration in regard to said scroll operation, and

adds directivity to the imparted friction force or vibration in regard to said scroll operation only after the user operates said operating feel control start icon.

11. The map display control device according to claim 10, wherein

said processor displays said operating feel control start icon at a position corresponding to an endpoint of said scroll operation on said touch panel.

12. The map display control device according to claim 1,

wherein after adding directivity to the imparted friction force or vibration in regard to said scroll operation, said processor executes an instruction from the user to stop adding directivity in regard to said scroll operation.

15. The map display control device according to claim 1 installable on a vehicle,

wherein said processor

acquires vehicle information containing information for use in specifying an expected travel route to be taken by said vehicle, and

sets, as said priority object, the expected travel route to be taken by said vehicle.

13. A map display control device comprising:

a processor to execute a program; and

a memory to store the program which, when executed by the processor, performs processes of,

acquiring map information,

causing a display to display a map based on said map information,

acquiring information on an operation performed by a user with an input device,

controlling a reaction force, vibration, or friction force imparted to said input device while the user performs said operation,

scrolling said map in step with a scroll operation performed by the user to scroll said map displayed on said display,

determining a priority object having higher priority than other objects contained in said map,

adding directivity to the imparted reaction force, vibration, or friction force in regard to said scroll operation in such a manner that, in a case where said priority object is located outside said map displayed on said display, a scroll operation for scrolling said map toward said priority object and a scroll operation for scrolling said map in any other direction arouse different magnitudes of the imparted reaction force, vibration or friction force,

causing said display to display an operating feel control end icon while said processor adds directivity to the imparted reaction force, vibration, or friction force in regard to said scroll operation, and

adding no directivity to the imparted reaction force, vibration or friction force in regard to said scroll operation once the user operates said operating feel control end icon.

14. The map display control device according to claim 13, wherein

said display and said input device constitute one touch panel, and

said processor displays said operating feel control end icon at a position corresponding to an endpoint of said scroll operation on said touch panel.

16. A method for controlling an operating feel aroused by map scrolling in a map display control device, said method comprising:

displaying a map based on map information on a touch panel;

determining a priority object having higher priority than other objects contained in said map;

scrolling said map in step with a scroll operation performed on said touch panel by a user to scroll said map displayed on said touch panel; and

adding directivity to a friction force or vibration imparted by said touch panel to a touch by the user while performing said scroll operation in such a manner that, in a case where said priority object is located outside said map displayed on said touch panel, a scroll operation for scrolling said map toward said priority object and a scroll operation for scrolling said map in any other direction arouse different magnitudes of the friction force or vibration.
