Abstract

Systems and methods are provided for controlling functions associated with a touch-sensitive device (100) capable of being worn by a user. The touch-sensitive device (100) includes a substrate (110) with an outside surface (112) and an inside surface (114) opposite from the outside surface (112). A first contact sensing component (120) generates a first signal upon detection of a first contact with the outside surface (112), and a second contact sensing component (130) generates a second signal upon detection of a second contact with the inside surface (114). A processor (140) may be configured to interface with the first contact sensing component (120) and the second contact sensing component (130) and perform operations including: analyzing the first signal and the second signal to determine that a predetermined condition is satisfied, and in response to the analyzing, initiating a function associated with the predetermined condition.
