Abstract

A method performed by a device having a touch-sensitive display may include displaying an image on the touch-sensitive display; detecting a touch on the touch-sensitive display; determining a type of the touch; associating a location of the touch with the image displayed on the touch-sensitive display; and generating a command signal based on the type of touch and the location of the touch on the touch-sensitive display.

Claims

1. A method performed by a device having a touch-sensitive display, the method comprising:

displaying an image on the touch-sensitive display;

detecting a touch on the touch-sensitive display;

determining a type of the touch;

associating a location of the touch with the image displayed on the touch-sensitive display; and

generating a command signal based on the type of touch and the location of the touch on the touch-sensitive display.

2. The method of claim 1, where the type of touch is one of a tap or a push.

3. The method of claim 1, where the touch-sensitive display includes a resistive touch panel.

4. The method of claim 1, where the touch is made by a deformable object.

5. The method of claim 1, where determining the type of touch comprises:

distinguishing between changing surface areas of a deformable object as the deformable object is depressed on the touch-sensitive display.

6. The method of claim 1, where determining the type of touch comprises:

comparing touch coordinates registered on the touch-sensitive display over a discreet time interval to distinguish a first type of the touch from a second type of the touch.

7. A device comprising:

a display to display information;

a touch-sensitive panel to identify a set of touch coordinates of a touch on the touch-sensitive panel;

processing logic to interpret the set of touch coordinates as one of a tap or a push;

processing logic to associate the touch coordinates with corresponding coordinates of the information on the display; and

processing logic to generate a command signal based on the interpreted set of touch coordinates and the corresponding coordinates of the information on the display.

8. The device of claim 7, where the touch-sensitive panel includes a resistive touch panel.

9. The device of claim 7, where the touch is made by a deformable object.

10. The device of claim 7, where the processing logic to interpret the set of touch coordinates as one of a tap or a push distinguishes between changing surface areas of a deformable object as the deformable object is depressed on the touch-sensitive panel.

11. The device of claim 7, where the processing logic to interpret the set of touch coordinates as one of a tap or a push compares touch coordinates registered on the touch-sensitive panel over a discreet time interval.

12. The device of claim 7, where the touch-sensitive panel is overlaid on the display.

13. The device of claim 7, further comprising:

a housing, where the touch-sensitive panel and the display are located on separate portions of the housing.

14. A computer-readable memory comprising computer-executable instructions, the computer-readable memory comprising:

one or more instructions for displaying an image on a touch-sensitive display;

one or more instructions for detecting a touch on the touch-sensitive display;

one or more instructions for identifying a location of the touch on the touch-sensitive display;

one or more instructions for identifying a type of the touch;

one or more instructions for associating the location of the touch and the type of the touch with the image displayed on the touch-sensitive display; and

one or more instructions for generating a command signal based on the type of the touch, the location of the touch on the touch-sensitive display, and the image on the touch-sensitive display.

15. The computer-readable memory of claim 14, where the type of touch is identified as one of a tap or a push.

16. The computer-readable memory of claim 14, where the touch-sensitive display includes a resistive touch panel.

17. The computer-readable memory of claim 14, where the touch is made by a deformable object.

18. The computer-readable memory of claim 14, where identifying a type of the touch comprises:

distinguishing between changing surface areas of a deformable object as the deformable object is depressed on the touch-sensitive display.

19. The computer-readable memory of claim 14, where identifying a type of the touch comprises:

comparing touch coordinates registered on the touch-sensitive display over a discreet time interval.

20. A device comprising:

means for displaying an image on a touch-sensitive display;

means for detecting a touch on the touch-sensitive display;

means for determining a kind of the touch;

means for identifying coordinates of the touch on the touch-sensitive display;

means for associating coordinates of the touch with the image displayed on the touch-sensitive display; and

means for generating a command signal based on the kind of touch and the coordinates of the touch on the touch-sensitive display.

21. A method performed by a device having a touch-sensitive panel comprising:

displaying an object on a screen;

identifying a first set of coordinates of a touch by a deformable object at a first time;

identifying a second set of coordinates of a touch by the deformable object at a second time;

associating the first set of coordinates and the second set of coordinates with the object on the screen; and

generating an input signal based on the object on the screen, the first set of coordinates and the second set of coordinates.
