Introduction - Purpose : To examine the relation between the time to make  rapid arm movements and the difficulty of the task. This  relation is expressed formally as Fitts’ Law, in which task  difficulty is defined in terms of the distance to move and the  accuracy demands at the end of the movement. Fitts’ Law has  been shown to generalize to a variety of physical activity and  ergonomic situations where speed and accuracy play important  roles.

Introduction - Hypotheses:  - As the index of difficulty increases, the number of  times the target was hit will decrease.  - As the index of difficulty increases, the movement  time will also increase.
