ABSTRACT

Measurements were made of the ability of subjects to identify vibrotactile patterns presented to their fingertips. The patterns were letters of the alphabet generated on the tactile display of the Optacon. Five different modes of pattern generation were examined. Two of the modes, static and scan, involved full-field presentations of the letters. In the remaining three modes, patterns were generated by presenting parts of the letters sequentially. In one mode, the letters were exposed by a slit passing across them. In the other two modes, the patterns were generated as though the letter were being drawn on the skin. Performance in all five modes was examined as a function of pattern duration, with durations ranging from 4 to 1,000 msec. Increasing duration, up to 400 msec, resulted in generally improved performance, although the functions relating performance and duration differed according to the mode of presentation. Contrary to previous results, the static mode produced the best overall performance level. Some possible reasons for the disagreement between the present results and previous results and some models of cutaneous pattern recognition are discussed. More... »

    25 schema:description Measurements were made of the ability of subjects to identify vibrotactile patterns presented to their fingertips. The patterns were letters of the alphabet generated on the tactile display of the Optacon. Five different modes of pattern generation were examined. Two of the modes, static and scan, involved full-field presentations of the letters. In the remaining three modes, patterns were generated by presenting parts of the letters sequentially. In one mode, the letters were exposed by a slit passing across them. In the other two modes, the patterns were generated as though the letter were being drawn on the skin. Performance in all five modes was examined as a function of pattern duration, with durations ranging from 4 to 1,000 msec. Increasing duration, up to 400 msec, resulted in generally improved performance, although the functions relating performance and duration differed according to the mode of presentation. Contrary to previous results, the static mode produced the best overall performance level. Some possible reasons for the disagreement between the present results and previous results and some models of cutaneous pattern recognition are discussed.
