Patent

CA 2527476

Aspects of the present invention reduce the number of false positive touch inputs made by a non-stylus object such as the user's finger or hand. When the stylus is located proximate to the touch-sensitive surface, the sensitivity of the surface to non-stylus input is disabled, reduced, or otherwise modified. For example, non-stylus inputs may be ignored while the stylus is within a proximity zone defined near the touch-sensitive surface. Further aspects of the present invention are directed to adjusting the threshold requirements of a non-stylus input depending upon where on the touch-sensitive surface the input is made. Still further aspects of the present invention are directed to calibrating various sensitivity thresholds for non-stylus input, as well as the size and/or shape of the proximity zone.
