Tactuator: A New Device for Sensory Substitution
The Tactuator is a new device developed for hearing impaired people. Our earlier work has demonstrated a potential information-transfer rate of 12 bits/sec with the Tactuator. Our long-term goal is to enable a deaf person to receive speech by feeling the signals delivered by the Tactuator. Recently, a new controller has been developed to enable the performance of the Tactuator to better match the perceptual capabilities of a human hand. We are currently conducting psychophysical experiments on the masking characteristics of signals presented to multiple fingers through the Tactuator. |
