N2 - Existing vision substitute systems provide insufficient information as a navigation system. To present spatial information in detail, we propose a stimulation method for transfer information enhancement by using a 2-D tactile stimulator array. Stimulators are divided into several groups. Since each stimulator group is activated alternately, the interval of stimulators can be shortened to less than the two-point discrimination threshold. In the case that stimulators are divided into two and four groups, the number of stimulators increase to twice and four times of that in the case of the two-point discrimination threshold. We examine and confirm this method experimentally.
