PROCEEDINGS OF THE HUMAN FACTORS SOCIETY-30th ANNUAL MEETING-I986 COMPARISON OF S I X CURSOR CONTROL DEVICES BASED ON FITTS ' LAW MODELS

Six cursor control devices were compared on a target acquisition task which required subjects to move a cursor into square targets of varying sizes and at various screen distances. The target acquisition performance data were fitted to movement time models proposed by Fitts, Jagacinski, and Kvalseth. Regression analysis results indicated good predictions of target acquisition performance for the six cursor devices. The best fit was obtained with the trackball across the three models
