Abstract

An embodiment of a system for controlling a graphical user interface of a device includes a tiltable member, an electrically conductive member, a substrate, a drive circuit, a switch, and signal logic. The tiltable member is configured for tilting by a user. The electrically conductive member is configured to move in response to the tilting. The substrate is spaced apart from the electrically conductive member by a gap and has mutually isolated sense electrodes disposed thereon. The drive circuit provides an electrical drive signal to the electrically conductive member. The switch is centrally located between the sense electrodes, wherein the tiltable member is connected to the switch to enable actuation of the switch in response to tilting of the tiltable member. The signal logic translates capacitance measurements and actuations of the switch into a signal that is indicative of an input function in a graphical user interface.
