a wirelessly controlled tactile display, consisting of a 4 × 4 array of vibrating motors that is mounted on a waist band or on the forearm. this tactile display can be used as a navigation aid outdoors, as experiments have proved that 8 different vibrotactile patterns can be interpreted as directional (e.g. stop, look left, run, proceed faster or proceed slower) or instructional cues (e.g. "raise arm horizontally", "raise arm vertically", "hop") with almost perfect accuracy.
