Human anticipation property of a free-falling object was experimentally studied by using a VR system, and the obtained results were compared to the results in real environment. Twelve participants were required to answer the anticipated position of free-falling virtual object at the visual stimulus onset, which was given after a specific interval of the object disappearance. The anticipated position increased proportionally to the interval, while the interval was varied from 30 to 190 ms. However, the slopes of the regression lines, which represent the anticipated velocities of the subjects, were five times smaller than the actual velocities. This unexpected slowdown was independent from the distance in virtual space. Therefore, this slowdown appears to be caused by the internal process of the recognition and anticipation, not the physical limitation such as the eye movement velocity.
