Abstract
A method of imitating a texture on a touch surface, the method including the steps of sensing a position of a user's finger on the touch surface, modulating a coefficient of friction of the touch surface in response to the sensed position of a user's appendage relative to the touch surface and/or a derivative thereof, where the friction modulator does not alter the contour of the touch surface in a manner that is perceptible to a user's sight or touch.
