Uzilla and EyeTrackingA group at Clemson is currently using eyetracking along with Uzilla to evaluate right vs left hand navigation bars. One of the questions I've been interested in is the proportion of time the mouse pointer and eye are in synch. Work by M. Rauterberg suggests in a click-driven UI, this correspondence is over 75%.
The work at Clemson will provide some ideas about deviations. Previous work with GOMS has identified fast-click, in which the pointer moves toward a target prior to the eye, versus slow click, where the mouse trails the eye. |||
