Abstract
A method of filtering a touch screen input is disclosed that includes the steps of detecting a position of a first touch on a touch screen, determining a validation area that includes the position of the first touch, detecting a position for each of one or more second touches on the touch screen, and providing a touch event signal if the positions of all of the second touches are within the validation area.
