Abstract: A multi-dimensional scroll wheel is disclosed. Scroll wheel circuitry is provided to detect input gestures that traverse the center of the scroll wheel and to detect multi-touch input. The scroll wheel can include a first plurality of sensor elements arranged in a first closed loop and a second plurality of sensor elements arranged in a second closed loop, the first and second closed loops being concentrically arranged about the center of the scroll wheel.
