Preliminary Study on Perceived Intensity of Electrovibration Using High-Frequency Carrier-Signal Voltage

— This short paper presents preliminary results from an experiment that investigated the effects of input voltage signals with a high frequency carrier on the perceived intensity of electrovibration. To measure the perceived intensity of stimuli, a fixed 6-point Effect Strength Subjective Index (ESSI) is used. Results indicated that the high frequency carrier enabled significantly increases in the intensity perception, as predicted in theory. In addition, the waveform of voltage signal affected the perceived intensity of electrovibration. Although preliminary, these findings suggest simple and effective methods for reducing the high voltage requirement of electrovibration devices.
