First Claim
1. A touchscreen system, comprising:
- a substrate, having a touch surface;
an electronic sensor integrated with said substrate adapted to detect multiple simultaneous touches at different arbitrary locations within a single continuous region on the touch surface, producing at least one sensor output signal representing a touch pattern; and
a control, receiving the at least one sensor output signal, being adapted to respond to at least two simultaneous touches from human fingers represented in the at least one sensor output signal, to determine a respective difference of at least one coordinate between the at least two simultaneous touches, and produce a response at least in dependence on a relationship of the at least two simultaneous touches.

Abstract
A system and method for processing input from a touchscreen having a substrate and a touch surface thereof, adapted for manual interaction with a human hand, having an electronic sensor associated with the substrate adapted to detect a pressure sensitive response to at least two concurrent touches on the touch surface, having a control which receives at least one signal representing the at least two concurrent touches on the touch surface; processes the at least one signal in a manner adapted to maintain a distinction between the at least two concurrent touches; determines a respective difference of at least one coordinate between the at least two concurrent touches; and responds by selectively producing a response at least in dependence on a relationship of the coordinate of the at least two concurrent touches.
