Abstract
A method of creating a haptic effect on a touch surface, the method including the steps of detecting a location of a first appendage and a second appendage on a touch surface, applying a mechanical force to the first and second appendages at the detected locations on the touch surface, modulating the amplitude of the mechanical force to adjust a friction force applied to the first appendage and second appendage to simulate a texture.
