Effects of optokinetic stimulation presented in a wide view on the sense of equilibrium

The sense of equilibrium is influenced by various factors of visual stimula tion, especially far peripheral vision and a motion parallax. An investigat ion of these two factors was made in order to apply the findings to constru ct a rehabilitation method for equilibrium disorders. From the experimental results, it was found that the center of gravity for the subjects was grea tly affected by both far peripheral vision and the motion parallax. This fi nding suggests how visual stimulation should be displayed to control the se nse of balance in the case of equilibrium disorders.
