Paper Abstract

The induced motion from visual information is discussed in showing the stable and moving images with or without disparities. Experiments were conducted to measure body sway, eye movement, and head movement under plane depth visual stimuli, to clarify the effect caused by the depth information for induced motion. Several obvious points emerged from the analysis of the experimental data. The minimal visual area needed to make the body stale is about 45 degrees for the plane stimuli, and is about 22.5 degrees of 45 degrees for the depth stimuli. It was also found that there are large differences in body sway between the plane stimuli and the depth stimuli after target moving. For the moving visual stimuli without disparity, the body sway was found to depend on the visual angle, but in the other case, it was found to be independent of the visual angle. This is due to the difference in OKN values from the measurement of eye movement. The frequency of emergence and the amplitude of OKN in the depth stimuli were larger than those of OKN in the plane stimuli. It was additionally observed that the low-frequency components of body sway were equal to those of head movement in these experiments.
