Real-time visual feedback about postural activity increases postural instability and visually induced motion sickness

It is possible to measure precisely the kinematics of postural activity, and to use these data to generate visual displays that provide real-time feedback about postural activity. Several studies have examined the effect of visual displays on the kinematics of standing posture, with mixed results. In some studies, real time visual displays have led to reduction in the spatial magnitude of body sway [1 –3]. In other studies, similar displays have had no effect on sway, or have been associated with increases in the spatial magnitude of sway [1,4–9].
