Tactile pattern recognition with the Optacon: superior performance with active touch and the left hand.
Independent groups of subjects (n = 12) attempted to identify individual digits 0-9 using active or passive touch with a vibrotactile display (Optacon II). Repeated measures were taken on the hand factor. Number recognition was superior with active touch and with the left hand.
