Abstract
AbstractIt has been shown that an inaccurate motor planning of a fast goal‐directed movement could be amended through an online comparison between the goal and the instantaneous representation of the (unseen) moving hand. The aim of this study was to test whether such an optimum processing was still efficient in a virtual visual environment (VE), by exploring the effect of immersion on the online visuomotor control of goal‐directed arm movement. Six subjects participated in the experiment, in which hand reaching toward either a stationary or a moving virtual visual target (double‐step paradigm) was executed in an upright posture. The analysis of the hand kinematics and postural adjustments showed an accurate control of movement and balance in both reaching conditions. This indicates that immersion does not affect the online control processes used by the CNS to adjust movement in interactive VE. Copyright © 2003 John Wiley & Sons, Ltd.
