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.
