Abstract
Our environmentally-based perceptual capacity is often challenged under crowded conditions like emergency evacuations. In order to achieve more effective direction guidance, we considered the use of unconscious reflexes in human walking. In this study, we experimented with vision-guided walking direction control by inducing subjects to shift their gaze direction using optical flow in peripheral visual field. We confirmed that a shift in a subject's walking direction could be induced by a combination of optical flow and vibratory stimulus on his legs. We propose a switching mechanism for visual and somatosensory input based on inducement timing.
