Abstract:
A user interface for an audio/visual device incorporates one or both of a touch sensor having a touch surface on which is defined a racetrack surface having a ring shape and a display element on which is displayed a racetrack menu also having a ring shape, and where the user interface incorporates both, the ring shapes of the racetrack surface and the racetrack menu are structured to generally correspond such that the position of a marker on the racetrack menu is caused to correspond to the position at which a digit of a user's hand touches the racetrack surface.
