Patent ID: 8587541

Claim:
A method for actuating a dynamic tactile interface comprising a tactile layer and a substrate, the method comprising: detecting a first input at a first location on a tactile surface of the tactile layer; detecting a second input at a second location on the tactile surface; identifying a gesture according to progression of the first input to a third location on the tactile surface and progression of the second input to a fourth location on the tactile surface; interpreting the gesture as a command associated with a deformable region of the tactile layer, the tactile layer defining the deformable region and a peripheral region, the peripheral region adjacent the deformable region and attached to the substrate opposite the tactile surface, the deformable region cooperating with the substrate to define a cavity, and the tactile surface at the deformable region arranged substantially between the first location and the second location and arranged substantially between the third location and the fourth location; and in response to the command, displacing fluid into the cavity to transition the deformable region from a retracted setting to an expanded setting, the tactile surface at the deformable region offset above the tactile surface at the peripheral region in the expanded setting.
