ABSTRACT:
The simulation of touch pressure on a touch-sensitive display is disclosed. In one disclosed embodiment, a touch pressure is simulated on a touch-sensitive display by detecting inputs corresponding to each of an untouched display and two or more measures of touch pressure, and displaying images on the display corresponding to the untouched display and each measure of touch pressure. In this manner, a user may be provided with a richer visual response to a touch-sensitive display input.
