Abstract

Seeing the position and motion of one's hand helps guide the hand to objects that one wants to interact with. If the latest available visual information guides the hand at each moment, slightly delaying access to such information should impede performance. We show that increasing the average delay by a few milliseconds, by briefly hiding the hand, does indeed increase the time it takes to reach a target.
