Pedestrian Guidance and Sensory Fusion Using Peripheral-Vision-Stimulus and Vibratory Stimulus

Recently, we have mobile adaptive information terminal to navigate like to present information during walking (ex. smartphone and glasses-type wearable terminal). On the other hand, attention to the surrounding environment is insufficient and incident is a familiar occurrence. It is considered to solve such a problem, it is important to behavior support by by measuring human behavior in real time and feedback information intuitive. 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 soma to-sensory feeling by a vibration stimulus on leg and foot area. In the 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. In this paper, we discuss on the unifying mechanism of visual and somatic sensations based on the experimental result.
