Patent attributes
A controller for an electronic system includes a controller body having a head and a handle, and a tracking member that is fixed to the controller body. The head includes at least one thumb-operated control, and the handle has a tubular housing that is partially wrapped by an outer shell. The controller includes a hand retainer configured to physically bias the user's palm against the outer shell. A first plurality of tracking transducers is disposed in the tracking member, the first plurality of tracking sensors being coupled with the electronic system via electromagnetic radiation. An array of proximity sensors is spatially distributed on the outer shell, the array of proximity sensors being responsive to a proximity of the user's fingers to the outer shell.
