Abstract
A touch screen display and corresponding devices and methods are disclosed, the touch screen display comprising a touchscreen having a plurality of capacitive sensors and a passive dial having one or more conductive elements, the passive dial mounted within an active area of the touchscreen such that the one or more conductive elements are proximate to the face of the touchscreen and move in conjunction with a rotation of the passive dial. The touch screen display may further include a touchscreen controller to detect an angle of the passive dial using conventional capacitive sensing techniques.
