Abstract

A method of controlling a portable electronic device that has a touch screen display includes providing a graphical user interface including an area defined by a boundary, detecting a touch event at a touch location within the area defined by the boundary on the touch screen display, determining if the touch location has moved to a new location outside of the area defined by the boundary; and performing an action in response to detecting the touch event at the touch location within the area defined by the boundary and determining that the touch location has moved from the area defined by the boundary to the new location outside of the area defined by the boundary.

Claims

1. A method comprising:

displaying, on a touch screen display of a portable electronic device, an area of an application including a boundary, wherein the boundary separates displayed data from displayed selectable features;

detecting a touch event at a touch location within the area;

determining when touch contact is maintained and the touch event moves to a new location outside of the area; and

performing an action in response to detecting that the touch event moved to the new location.

2. The method according to claim 1, wherein performing the action comprises displaying different information within the area.

3. The method according to claim 1, comprising determining a direction of change of the touch contact, and displaying different information based on the direction of change.

4. The method according to claim 1, wherein performing the action comprises scrolling based on the direction of change of the touch contact.

5. The method according to claim 1, comprising determining when the touch event moves prior to determining when the touch event moves to a new location outside of the area and, when the touch event ends absent the touch event having moved, selecting a feature in the area based on the touch location.

6. The method according to claim 1, comprising determining when the touch event moves to a further new location outside of the area, displaying different information within the area.

7. The method according to claim 1, wherein performing the action comprises scrolling.

8. The method according to claim 7, comprising further scrolling while touch contact is maintained at the location outside the area.

9. The method according to claim 7, wherein a speed of the scrolling is based on a distance of the new touch location from the boundary.

10. The method according to claim 7, wherein a speed of the scrolling increases with distance of the new touch location from the boundary.

11. The method according to claim 7, comprising determining a distance from the new location to the boundary and determining a delay time based on the distance prior to scrolling.

12. The method according to claim 11, wherein the delay time decreases with an increase in the distance to increase a scrolling speed.

14. A non-transitory computer-readable device having computer-readable code embodied therein and executable by a processor to perform the method of claim 1.

15. The method according to claim 1, wherein the displayed data comprises data from the application and the displayed selectable features comprise icons from the application.

13. A portable electronic device comprising:

a touch screen display;

a processor coupled to the touch screen display and configured to;

display, on the touch screen display, an area defined by a boundary, wherein the boundary separates displayed data from displayed selectable features,

detect a touch event at a touch location within the area on the touch screen display,

determine when touch contact is maintained and the touch event moves to a new location outside of the area, and

perform an action in response to detecting that the touch contact event moved to the new location.

16. A method comprising:

providing a graphical user interface for an application on a touch screen display of a portable electronic device, wherein the graphical user interface includes a first area of the application and a second area of the application, wherein the first area has a boundary that separates displayed data in the first area from selectable features displayed in the second area;

detecting a touch event at a touch location within the first area on the touch screen display;

determining when touch contact is maintained and the touch event moves to a new location outside the first area, wherein the new location is within the second area;

performing an action in response to detecting that the touch event moved to the new location.

17. The method according to claim 16, wherein a selectable feature is separately selectable upon detection of a touch event beginning and ending at the selectable feature.

18. The method according to claim 16, wherein performing the action comprises scrolling in a direction dependent on a direction of change of the touch contact within the first area and the second area.

19. The method according to claim 16, wherein a speed of the scrolling is based on a distance of the new touch location from the boundary.

20. A method comprising:

displaying, on a touch screen display of a portable electronic device, a first area of the application and a second area of the application, wherein the first area has a boundary that separates displayed data in the first area from selectable features displayed in the second area;

detecting a touch event at a touch location within the first area on the touch screen display;

determining when touch contact is maintained and the touch event moves to a new location outside the first area, wherein the new location is within the second area;

scrolling the displayed data in the first area in response to detecting that the touch event moved to the new location.

21. The method according to claim 20, wherein a direction of scrolling is dependent on a direction of movement of the touch event to the new location and the speed of scrolling is based on a distance of the new location from the boundary.
