Question

Quizplus · Accepted Answer

Fitts' Law relates the task difficulty of a rapid manual aiming task to the ratio of the distance to be moved and the size of the target. This means that the greater the distance to be moved, or the smaller the target, the more difficult the task and the longer it will take to complete. Therefore, there is a speed-accuracy trade-off, as the participant must balance their movement speed with their accuracy to complete the task as quickly and accurately as possible.
