Abstract

P. M. Fitts (J. Expt. Psychol., vol. 47, p.381-91, 1954). presented a relationship between speed, accuracy, amplitude of movement, and target size in upper extremity tasks (Fitts´ Law). Fitts´ Law, however, is established only for translational motion. Here, a similar relationship is proposed for describing angular motion. Experiments were conducted for one degree of freedom of the upper extremity to establish initial values for an angular motion neuromuscular channel capacity. It is anticipated that a finite set of such metrics representing “available performance resources” used with a suitable model could be used to predict performance in any task involving one or more jointed body segments
