Patent ID: 8717326

Claim:
A user interface system comprising: an elastic membrane comprising a deformable region and a peripheral region adjacent the deformable region; a substrate coupled to the membrane along a perimeter of the deformable region, cooperating with the deformable region to define a cavity, and defining a fluid channel fluidly coupled to the cavity; a tactile layer arranged over the membrane opposite the substrate, disconnected from the deformable region, and coupled to the membrane at an area outside of the perimeter of the deformable region; a displacement device configured to displace fluid into the cavity via the fluid channel to transition the deformable region from a deflated setting into an inflated setting, the deformable region substantially flush with the peripheral region in the deflated setting and raised above the peripheral region in the inflated setting; a display coupled to the substrate and configured to display an image proximal the deformable region; a sensor arranged across the substrate opposite the membrane; and a processor configured to detect an input on the tactile layer proximal the deformable region in response to an output of the sensor.
