Effects of feedback delay on eye-hand synchronism in steering behavior

Abstract

Used real-time computer methods of controlling feedback factors in eye tracking to compare accuracy in tracking environmentally-generated and hand-generated visual targets in steering behavior of 5 undergraduates. Feedback delays of .1 and .2 sec. between hand and target movement produced a time lag of eye motion with respect to the hand-produced target action. Results confirm the assumption that steering and stimulus tracking represent different modes of response and are subject to different conditions of delay and displacement of action feedback of body movements. The main effect of feedback delays on eye tracking in steering was to restrict the normal capability of the eye to predict the course of self-generated stimulus movements by reducing the interval of time between hand action and eye response beyond the magnitude of the actual delay interval.
