Abstract: There is disclosed a multi-dimensional user interface controller apparatus for providing a multi-dimensional user input. In an embodiment, the apparatus comprises a disc adapted to be tilted to control at least two-axes, and depressible in a third axis, and an outer ring surrounding the disc, the outer ring adapted to rotate about the disc to control a fourth axis. In use, the disc and the outer ring are controllable to provide at least four-axes of simultaneous control inputs. In an embodiment, the multi-dimensional user interface controller apparatus further comprises a plurality of magnetic sensors to sense the tilt of the disc or a press on the disc. In another embodiment, the disc further comprises a touch-sensitive top surface adapted to sense one or more fingers touching the surface.
