Evaluation of static and dynamic equilibrium before and after immersion in a virtual environment

The effectiveness of VR (virtual reality) systems is well documented, but there are no guidelines for determining the influence that such systems have on humans, particularly with regard to adaptation to the VR environment. The results of an experiment are summarized as follows: 1) A VR experience using an HMD made the integration of sensory information in the equilibrium nucleus confusing. 2) Sensory conflict caused motion-sickness-like symptoms in the subjects. 3) As a result of equilibrium deterioration, movement velocity, movement distance, and sway area of the center of pressure were increased. These results suggest that the VR experience causes motion-sickness-like symptoms and worsens equilibrium.
