LAB 2: SPEED AND ACCURACYKIN 31511720Abby Lindemuth, Lexie Dolan, Jacqueline Brustkern, Patrick Murphy TA: Xueyan ZhaoWednesday, February 12, 2014
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.
