Electrocutaneous Tracking: A Methodology for Evaluating Sensory Feedback Codes

An objective and relevant methodology for evaluating sensory feedback codes has been developed using electrocutaneous tracking. This methodology involves dynamic (or continuous) interpretation and response by a subject to electrically produced cutaneous sensations. Results from the comparison of ten codes are briefly presented here to show the usefulness of this methodology. A general purpose computer-controlled electrocutaneous stimulation facility being developed is expected to expedite the examination of many other sensory feedback codes.
