Quizplus · Accepted Answer

Fitts' law models the time required to rapidly move to a target area as a function of the ratio between the distance to the target and the width of the target. It is specifically concerned with the time to move a cursor or another pointing device to a fixed target area, not with accuracy or tracking moving targets.
