Abstract
Started in the 1960's, Several Type of Walking Aid Vision Substitution Device for visually impaired have been developed. The acute problem of these vision tactile substitution systems is the low amount of information causing the low tactile sensory resolution. Therefore, the most of system adopts the surrounding distance-tactile signal conversion, and it yet not enough to transmit surrounding state to user. This study aims at transmitting the position of human being using face-catch technology and new tactile display, and bring user to act, not passive, but active and voluntary communication.
