Modeling of Pedestrian Guidance by Sensory Fusion Using Peripheral Vision Display and Vibration Device

Abstract

Human walking is affected by vision, vestibular, somatic and other various sensations that come through the sensory-motor loop. But detail of the sensory-motor loop is not clear. In this study, we examined a possible affect of self motion sensation by an optical-flow stimulus in peripheral vision with a decayed somato-sensory feeling by a vibration stimulus on leg and foot area. In this experiment, we presented the optical flow for forward direction to the peripheral vision, and then gave the self-motion sensation by changing the flow to left or right direction. We examine the change of walking direction toward opposite of the self-motion sensation because of the decayed somato-sensory feeling. In this paper, we discuss on the sensory fusion mechanism of visual and somatic sensations based on the experimental result.
