Existing vision substitute systems are not useful as navigation system due to the limitation of spatial and time resolution. In this study we propose a transmit control method free from range aliasing for a high resolution acoustic vision substitute systems, which we previously proposed. We also examine a human-machine information transfer method with a vibrotactile stimulator array consisting of 13 times 21 elements. It presents the target area of 30 degree times 60 degree by the sampling interval of 1 degree at the center. The system presents range, direction, and surface topography of targets to the subject
