Abstract

A high-resolution electrotactile feedback display has been built and is being evaluated as a feedback channel for improving the dynamic control of mechanically powered prosthetic arms. While the device combines various concepts from previous research on the subject, the addition of much higher resolution dramatically reduces the noise from quantization of the signal, and the preliminary results are encouraging. Dynamic tracking performance using electrotactile feedback is beginning to approach the baseline performance of tracking tasks using visual feedback. A simple controls system model of the situation is being developed to explain the observed performance
