Abstract

A method of controlling a portable electronic device that has a touch screen display includes providing a graphical user interface on a touch screen display, detecting a touch event at a first location on the touch screen display, providing a navigation indicator in the graphical user interface in response to detecting the touch event at the first location, and in response to detecting movement of the touch event from the first location to a second location while touch contact is maintained on the touch screen display, changing the position of the navigation indicator in the graphical user interface by a distance that is greater than a distance of movement of the touch event on the touch screen display, a direction of change of position of the navigation indicator is based on a direction of movement of the touch event on the touch screen display.

Claims

1. A method of controlling a portable electronic device having a touch screen display, the method comprising:

providing a graphical user interface on the touch screen display;

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

providing a navigation indicator in the graphical user interface in response to detecting the touch event at the first location; and

in response to detecting movement of the touch event from the first location to a second location while touch contact is maintained on the touch screen display, changing the position of the navigation indicator in the graphical user interface by a distance that is greater than a distance of movement of the touch event on the touch screen display, a direction of change of position of the navigation indicator is based on a direction of movement of the touch event on the touch screen display.

2. The method according to claim 1, wherein changing the position of the navigation indicator in the graphical user interface comprises moving the navigation indicator relative to at least a portion of the graphical user interface.

3. The method according to claim 2, wherein moving the navigation indicator relative to the portion of the graphical user interface comprises scrolling said portion of the graphical user interface if the navigation indicator reaches an edge of said portion.

4. The method according to claim 3, wherein moving the navigation indicator relative to the portion of the graphical user interface comprises moving the navigation indicator relative to the touch screen display prior to the navigation indicator reaching the edge.

5. The method according to claim 1, comprising selecting a feature at the navigation indicator in response to receipt of an input from a switch actuated as a result of movement of the touch screen display relative to a remainder of the portable electronic device.

6. The method according to claim 5, comprising performing a function in response to receipt of said input.

7. The method according to claim 1, wherein the distance of change of position of the navigation indicator in the graphical user interface is based on a fixed multiple of the distance of movement of the touch.

8. The method according to claim 1, wherein the distance of change of position of the navigation indicator in the graphical user interface is based on a variable ratio of distance of movement of the touch event to the distance of change of position of the navigation indicator.

9. The method according to claim 8, wherein the variable ratio depends on a distance of the navigation indicator from the touch event.

10. The method according to claim 8, comprising determining a speed of movement of the touch event from the first location to a second location in response to detecting movement of the touch event from the first location to a second location while touch contact is maintained on the touch screen display.

11. The method according to claim 10, wherein the variable ratio depends on the speed of movement of the touch event.

12. The method according to claim 1, wherein said navigation indicator comprises a cursor or highlighting.

13. A portable electronic device comprising:

a touch screen display; and

functional components including a processor connected to the touch screen display, and a memory device for storage of computer-readable program code executable by the processor for providing a graphical user interface on the touch screen display, detecting a touch event at a first location on the touch screen display, providing a navigation indicator in the graphical user interface in response to detecting the touch event at the first location, and in response to detecting movement of the touch event from the first location to a second location while touch contact is maintained on the touch screen display, changing the position of the navigation indicator in the graphical user interface by a distance that is greater than a distance of movement of the touch event on the touch screen display, a direction of change of position of the navigation indicator is based on a direction of movement of the touch event on the touch screen display.

14. A computer-readable medium having computer-readable code embodied therein for execution by a processor of a portable electronic device for providing a graphical user interface on a touch screen display, detecting a touch event at a first location on the touch screen display, providing a navigation indicator in the graphical user interface in response to detecting the touch event at the first location, and in response to detecting movement of the touch event from the first location to a second location while touch contact is maintained on the touch screen display, changing the position of the navigation indicator in the graphical user interface by a distance that is greater than a distance of movement of the touch event on the touch screen display, a direction of change of position of the navigation indicator is based on a direction of movement of the touch event on the touch screen display.
