Abstract

A method and method for displaying an image via a graphical user interface on a touch-sensitive display of an electronic device includes detecting a predetermined relation between a selection tool and the image. The image is panned in response to movement of the selection tool along the touch-sensitive display. The image is zoomed on in response to depression of the touch-sensitive display. An optional cursor may be activated upon detection of a first tap of the selection tool on the touch-sensitive display.

Claims

1. A method comprising:

displaying an image via a graphical user interface on a touch-sensitive display of an electronic device;

detecting a predetermined relation between a selection tool and the image;

panning the image in response to movement of the selection tool along the touch-sensitive display; and

zooming on the image in response to depression of the touch-sensitive display.

2. The method of claim 1, wherein the image is highlighted in response to detection of the predetermined relation between the selection tool and the image.

3. The method of claim 1, wherein the selection tool is conductive and detecting comprises detecting the selection tool spaced from the touch-sensitive display.

4. The method of claim 1, wherein the selection tool is conductive and detecting comprises detecting the selection tool touching the touch-sensitive display.

5. The method of claim 1, further comprising displaying a zoom menu in response to the depression of the touch-sensitive display.

6. The method of claim 5, further comprising deactivating the zoom menu when the selection tool is not detected for more than a predetermined time.

7. The method of claim 1, further comprising detecting a first tap of the selection tool on the touch-sensitive display and activating a cursor on the touch-sensitive display.

8. The method of claim 7, further comprising moving the cursor on the touch-sensitive display in response to movement of the selection tool in relation to the touch-sensitive display.

9. The method of claim 8, further comprising detecting a depression of the touch-sensitive display and selecting the image with a predetermined relation to the detected depression of the touch-sensitive display.

10. The method of claim 7, further comprising panning the image in response to cursor movement at an edge of a boundary of the touch-sensitive display.

11. The method of claim 10, further comprising detecting a second tap of the touch-sensitive display and deactivating the cursor.

12. The method of claim 11, further comprising activating a default operating mode after the cursor has been deactivated, wherein the default operating mode facilitates panning of the image in response to selection tool movement along the touch-sensitive display and zooming on the image in response to depression of the touch-sensitive display.

13. The method of claim 1, further comprising detecting a first tap on the touch-sensitive display and activating a cursor, wherein the cursor tracks the movement of the selection tool in relation to the touch-sensitive display, and further comprising detecting a subsequent tap of the touch-sensitive display by the selection tool and selecting an image with a predetermined relation to a location of the detected subsequent tap.

14. The method of claim 13, further comprising detecting removal of the selection tool from the touch-sensitive display for a predetermined period of time, deactivating the cursor, and activating a default operating mode, wherein the default operating mode facilitates panning of the image in response to selection tool movement along the touch-sensitive display and zooming on the image in response to detecting depression of the touch-sensitive display.

15. The method of claim 1, wherein the selection tool is one of a finger of a user and a conductive stylus.

16. The method of claim 1, wherein the predetermined relation is a capacitance value.

17. A computer readable medium having stored instructions for execution by a processor of a mobile device and for causing the mobile device to implement the method of claim 1.

18. An electronic device including a touch-sensitive display, the device comprising:

a body housing a touch-sensitive display comprising a display screen, a touch location sensor, and a cover lens;

a switch operably coupled to the cover lens;

a microprocessor in data-communication with the display screen, the touch location sensor, and the switch; and

a microprocessor programmed to;

display a image on the touch-sensitive display;

detect a predetermined relation between a selection tool and the image;

pan the image in response to movement of the selection tool along the touch-sensitive display; and

zoom on the image in response to depression of the touch-sensitive display.

19. The electronic device of claim 18, where the depression is detected by detecting depression of the touch-sensitive display by the selection tool.
