Abstract

A method performed by a device having a touch panel may include detecting a touch on the touch panel, determining a dimension of the touch, identifying the touch as a standard tap or a full tap based on the dimension of the touch, and generating a command signal based on the identifying of the touch as the standard tap or the full tap.

Claims

1. A method performed by a device having a touch panel, the method comprising:

detecting a touch on the touch panel;

determining a dimension of the touch;

identifying the touch as one of a standard tap or a full tap based on the dimension of the touch;

generating a command signal based on the identifying the touch as one of the standard tap or the full tap; and

performing an action based on the command signal.

2. The method of claim 1, where determining the dimension of the touch comprises:

determining a horizontal dimension of the touch, and

determining a vertical dimension of the touch.

3. The method of claim 1, where determining the dimension of the touch comprises:

determining if there is symmetry between two dimensions of the touch.

4. The method of claim 1, where the touch panel includes a capacitive touch panel.

5. The method of claim 1, where the touch panel comprises projection scanning technology.

6. The method of claim 1, further comprising:

determining a touch baseline for a standard tap or a full tap of a particular user.

7. The method of claim 6, where user input for the touch baseline is passively obtained.

8. A device comprising:

a display to display information;

a touch panel to identify a touch on the touch panel;

processing logic to interpret the touch as one of a standard tap or a full tap;

processing logic to generate a command signal based on the interpretation of the touch as the standard tap or the full tap; and

processing logic to alter the display based on the command signal.

9. The device of claim 8, where the touch panel includes a capacitive touch panel.

10. The device of claim 8, where the touch panel comprises projection scanning technology.

11. The device of claim 8, where the processing logic to interpret the touch as one of the standard tap or the full tap determines a horizontal dimension of the touch and a vertical dimension of the touch.

12. The device of claim 8, where the processing logic to interpret the touch as one of the standard tap or the full tap determines if there is symmetry between two dimensions of the touch.

13. The device of claim 8, where the touch panel is overlaid on the display.

14. The device of claim 8, further comprising:

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

15. The device of claim 8, further comprising:

processing logic to determine a touch baseline for a particular user, and

a memory to store the touch baseline.

16. The device of claim 8, further comprising:

a memory to store standard tap or full tap dimensions appropriate for a median range of prospective users, where the processing logic to interpret the touch compares the touch on the touch panel to the standard tap or full tap dimensions.

17. The device of claim 8, the touch panel comprises one of optical technology or pressure sensitive technology to determine the dimension of the touch.

18. A device comprising:

means for displaying an image on a display;

means for detecting a touch on a touch panel associated with the display;

means for determining a dimension of the touch;

means for identifying a type of the touch based on the dimension of the touch;

means for identifying coordinates of the touch on the touch panel;

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

means for generating a command signal based on the type of the touch and the coordinates of the touch associated with the image displayed on the display.

19. The device of claim 18, where the type of the touch is one of a standard tap or a full tap.

20. The device of claim 18, further comprising:

means for establishing a touch baseline for one of a standard tap or a full tap, where the means for identifying a type of the touch compares the dimension of the touch to the touch baseline.
