MULTIPLE INPUT DETECTION FOR RESISTIVE TOUCH PANEL
First Claim
Patent Images
1. A method performed by a device having a touch-sensitive panel, the method comprising:
- detecting touch coordinates of a touch on the touch-sensitive panel;
measuring a current though at least a portion of the touch-sensitive panel;
comparing the measured current with a threshold current;
identifying the touch as a multiple touch based on the comparison of the measured current with one or more particular current range; and
generating a command signal corresponding to the multiple touch.

Abstract
A method performed by a device having a touch-sensitive panel includes detecting touch coordinates of a touch on the touch-sensitive panel and measuring a current though at least a portion of the touch-sensitive panel. The method further includes comparing the measured current with a threshold current and identifying the touch as a multiple touch based on the comparison of the measured current with a threshold current. The method may also include generating a command signal corresponding to the multiple touch.

8. A device comprising:
-
a display to display information; a touch-sensitive panel to identify touch coordinates of a touch on the touch-sensitive panel; an indicator to measure current through at least a portion of the touch-sensitive panel; processing logic to interpret the touch as one of a single touch or a dual touch based on the measured current; and processing logic to generate a command signal to alter the display based on the interpreted touch. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15)
