An electromechanical transducer was modified for use as a vibrotactile stimulus. Response time to the vibrotactile stimulus was measured experimentally at various levels of stimulus-signal amplitude and frequency. Stimulus-signal amplitude levels ranged from 0.1 to 1.6 mm and frequency levels ranged from 30 to 800 Hz. Experimental results indicate that response time to the vibrotactile stimulus quickens with increasing amplitude and frequency and further that response time appears to be converging to an optimum over the range tested.
