Abstract

A method for registering user interaction with a dynamic tactile interface, which includes a tactile layer defining a tactile surface, a deformable region, and a peripheral region and coupled to a substrate opposite the tactile surface, the deformable region cooperating with the substrate to form a variable volume. The method includes detecting a first contact of an object at a first location on the tactile surface at a sensor; detecting a removal of the object from the first location; at a first time, detecting a first pressure of the variable volume at a pressure sensor; at the sensor, at a second time after the first time, detecting a second contact at a second location; at the second time, detecting a second pressure at the pressure sensor; interpreting the first and second contact, and the pressure difference as a gesture; and executing a command corresponding to the gesture.
