We investigated the effects of tracking eye movements on predicting a future position of a three-dimensional moving object. Each stimulus movie was composed of four object frames. The participants judged whether the fourth object frame contained an object which had been changed an equivalent amount to the object in the second and third object frames. The results showed that tracking eye movements are required to accurately predict the future position of a moving object although cast shadows are also necessary for the prediction of the three-dimensional rotation. The results therefore imply the existence of a labeling mechanism which is mediated by tracking eye movements.
