Differential visual feedback of component motions

Abstract

New closed-circuit television techniques allowed the joint action of S's hand, control-instrument, and operational effects to be visually fed back singly or in combination. 8 visual feedback conditions and 2 levels of task precision were used. The results showed that the effects of visual feedback were determined by the component motions fed back, with the operational effects being the most important followed by control-instrument and hand-arm movements. A significant interaction between visual feedback and precision of movement occurred, where feedback of the operational component became more important as more overall precision of movement was demanded.
