title: Two-Tactor Vibrotactile Navigation Information for the Blind: Directional Resolution and Intuitive Interpretation.
abstract: Lacking vision, blind people have to exploit other senses for navigation. Using the tactile rather than the auditory sense avoids masking important environmental information. Directional information is particularly important and traditionally conveyed through an array of tactors, each coding one direction. Here, we present a different approach to represent arbitrary directions with only two tactors. We tested intuitiveness, plasticity, and variability of direction perception in a behavioral experiment in 33 seeing participants.
