Abstract

A method includes detecting a touch beginning at a first location on a touch-sensitive display of a portable electronic device, wherein the touch-sensitive display has a first area and second area. The method also includes, when the touch begins, filtering touch data comprising further processing the touch data when the first location is associated with the first area, and disregarding the touch data associated with the touch when the first location is associated with the second area.

Claims

1. A method comprising:

detecting a touch beginning at a first location on a touch-sensitive display of a portable electronic device, wherein the touch-sensitive display has a first area and second area;

when the touch begins, filtering touch data comprising;

further processing the touch data when the first location is associated with the first area; and

disregarding the touch data associated with the touch when the first location is associated with the second area.

2. The method according to claim 1, wherein further processing comprises reporting the touch to an application layer.

3. The method according to claim 1, wherein the first location comprises the first detected touch location.

4. The method according to claim 1, wherein disregarding the touch data comprises a disregarding the first detected touch location and all subsequent data associated with the touch.

5. The method according to claim 1, wherein filtering is discontinued when a keyboard is displayed on the touch-sensitive display.

6. The method according to claim 1, wherein filtering is controlled by an application associated with information displayed on the touch-sensitive display.

7. The method according to claim 1, wherein the second area comprises an area near a navigation device of the portable electronic device.

8. The method according to claim 1, wherein the second area comprises an area along an edge of the touch-sensitive display, which edge is near a navigation device of the portable electronic device.

9. The method according to claim 1, wherein the second area comprises an area that extends a distance of less than 10 pixels from an edge of the touch-sensitive display.

10. The method according to claim 1, wherein the first area and the second area cover a face of the touch-sensitive display.

11. The method according to claim 1, wherein the second area extends at least partially over a non-display area of the touch-sensitive display.

12. The method according to claim 1, wherein the second area is adjacent a single edge of the touch-sensitive display.

13. The method according to claim 1, wherein the size of the second area is related to the distance from the navigation device to the touch-sensitive display.

14. A computer-readable medium having computer-readable code executable by at least one processor of a portable electronic device to perform the method according to claim 1.

15. A portable electronic device comprising:

a touch-sensitive display;

a navigation device;

a processor operably coupled to the touch-sensitive display to detect a touch beginning at a first location on the touch-sensitive display, wherein the touch-sensitive display has a first area and second area, and when the touch begins, filter touch data by further processing the touch data when the first location is associated with the first area, and disregarding the touch data associated with the touch when the first location is associated with the second area.

16. The electronic device according to claim 15, wherein the first location comprises the first detected touch location.

17. The electronic device according to claim 15, wherein the second area is along an edge of the touch-sensitive display, which edge is near the navigation device.

18. The electronic device according to claim 15, wherein the second area extends over at least a portion of a non-display area of the touch-sensitive display.

19. The electronic device according to claim 15, wherein touch data that is disregarded comprises a first detected touch location and subsequently received data associated with the touch.

20. A method comprising:

detecting a touch beginning at a first location on a touch-sensitive display of a portable electronic device;

determining when the first location is associated with a predetermined area of the touch-sensitive display;

when the touch is associated with the predetermined area, disregarding the touch data associated with the touch.
