US Patent 9280234 Input correction for touch screens

A system and method determines whether a finger touch on a touch screen device is outside the defined boundary of a touch target. In such situations a device may adjust the location coordinates of the finger touch to adaptively correspond to an appropriate touch target based on such factors as context, region, distance from touch target, user history, device movement, parallax, etc. The method and system may also be applied to overlapping touch targets.
