Abstract
A method and apparatus for generating haptic surface texture with a deformable surface layer are disclosed. The haptic device includes a flexible surface layer, a haptic substrate, and a deforming mechanism. The flexible surface layer is made of elastic materials and is capable of reconfiguring its surface characteristics. The haptic substrate, in one embodiment, provides a first pattern in response to a first activating signal. Alternatively, the haptic substrate is capable of providing a second pattern in accordance with a second activating signal. The deforming mechanism is configured to change the flexible surface from a first surface characteristic to a second surface characteristic in accordance with the first pattern.
