USER INTERFACE AND METHODS

摘要

One variation of a method for controlling a dynamic tactile user interface includes: sensing a first capacitance value across a portion of a cavity in a retracted setting; sensing a second capacitance value across a peripheral region; generating a capacitance map according to the first capacitance value and the second capacitance value; modifying a fluid pressure within the cavity to transition the cavity into an expanded setting, the deformable region elevated above the peripheral region in the expanded setting; sensing a third capacitance value across the portion of the cavity in the expanded setting; updating the capacitance map according to the third capacitance value; and detecting an input on the tactile surface at the deformable region according to a comparison between a sensed capacitance value across the portion of the cavity and the capacitance map.
