Motivated by the highly successful Tadoma method of speech communication, a multi-finger positional display (the TACTUATOR) was developed to study perception via the kinesthetic and vibrotactile aspects of the tactual sensory system of the hand. The information transmission capabilities with the TACTUATOR were assessed through a series of absolute identification experiments. An information transfer (IT) of 5.6 to 6.5 bits for stimulus durations of 125 to 500 msec was obtained in absolute-identification experiments with sets of signals derived by varying frequency, amplitude, and site of stimulation of multicomponent waveforms. An estimated IT rate of 12 bits/sec was obtained by sequencing three random stimuli and (a) having the subject identify only the middle stimulus and (b) extrapolating this IT to that for continuous streams. This IT rate is roughly the same as that achieved by Tadoma users in tactual speech communication.
