Two groups of participants (novice and advanced) completed a study comparing a prototype game controller to a standard game controller for point-select tasks.

We used Fitts' law as per ISO 9241--9 to evaluate the pointing performance of both controllers. In the novice group, the trackball controller's throughput was 2.69 bps -- 60.1% higher than… CONTINUE READING
