User interface and methods
First Claim
1. A method for controlling a dynamic tactile user interface comprising a tactile layer and a substrate, the method comprising:
- sensing a capacitance value across a portion of a cavity, the tactile layer defining a deformable region and a peripheral region, the peripheral region adjacent the deformable region and coupled to the substrate opposite the tactile surface, and the deformable region cooperating with the substrate to define the cavity;
estimating a vertical position of the tactile surface at the deformable region according to the sensed capacitance value across the portion of the cavity;
manipulating a fluid pressure within the cavity to modify a vertical position of the tactile surface at the deformable region according to a difference between the estimated vertical position of the tactile surface at the deformable region and a target vertical position of the tactile surface at the deformable region; and
sensing an input on the tactile surface at the deformable region according to a change in capacitance value across the portion of the cavity.
