Claim Text:
1. A system for simulating materials using a touch surface, comprising: a touch surface for an electronic device; at least one temperature control device operable to control a temperature of at least a portion of the touch surface; at least one actuator operable to vibrate the portion of the touch surface; and at least one control unit that controls the at least one temperature control device and the at least one actuator to cause the portion of the touch surface to simulate a material; wherein: the at least one control unit varies the temperature of the portion of the touch surface based on a duration of a touch to simulate the material changing temperature in response to the touch over the duration; and the at least one control unit controls heat produced by the at least one actuator to prevent interference with the simulation of the temperature of the material with the touch surface.
