Abstract
Identifying characteristics integrated in a totem and detected by a capacitive display mat are applied to perform functions in response to end user inputs. Identifying characteristics include capacitive feet integrated in a totem bottom surface with identifying features including varying capacitive values for the feet, varying pad sizes and shapes, varying pad patterns and varying capacitive oscillation frequencies. In one embodiment, the surface area of the totem in contact with the capacitive mat varies depending upon the pressure placed on the totem to alter the shape of a compressible material disposed at the bottom surface.
