Abstract:

Subjects performed two-dimensional discrete movements either with a helmet-mounted sight or with a joystick. Fitts Law was found to be a good predictor of the speed-accuracy tradeoff for both systems. The joystick produced faster movement times than the helmet-mounted sight. For both systems, horizontal and vertical movements were slightly faster than diagonal movements. Two-dimensional generalizations of Fitts Law were discussed in terms of multi-dimensional scaling. The obtained pattern of movement times was found to be intermediate to the predictions of Euclidean and City-block models of the movement spaces. Muscle coordination strategies were considered and strictly parallel coordination models were rejected. Author
