This video shows the Trackball Controller prototype. It was built based on the belief that an analog stick is poorly suited for pointing and camera control. To date, we have evaluated the controller in two studies.

One showed that the trackball represents a 60% improvement over the analog stick in terms of pointing (speed & accuracy).

The other showed that participants were able to complete the Call of Duty 4: Modern Warfare cargo ship mock-up 10% faster with the Trackball Controller than a standard Xbox 360 controller (though they were experienced with an Xbox 360 controller but not our prototype).
