Summary: 
The sense of equilibrium is influenced by various factors of visual stimulation, especially far peripheral vision and a motion parallax. An investigation of these two factors was made in order to apply the findings to construct a rehabilitation method for equilibrium disorders. From the experimental results, it was found that the center of gravity for the subjects was greatly affected by both far peripheral vision and the motion parallax. This finding suggests how visual stimulation should be displayed to control the sense of balance in the case of equilibrium disorders.
