Abstract

Existing vision substitute systems have insufficient spatial resolution to provide environmental information. To present detailed spatial information, we propose a stimulation method to present the target range accurately using a 2-D tactile stimulator array. A user selects the measurement range and the system presents targets within the range. The user changes the measurement range, and then compares the presented targets in the latter measurement range with that in the former one. The targets, presented in one measurement range and not in the other measurement range, exist between the former and latter ranges. We examine and confirm this method experimentally.
