COMMUNICATION WITHOUT CONVENTIONAL (ELECTRO-MECHANICAL) ACOUSTIC TRANSDUCERS.
Abstract
A tactile transducer provided stimulation composed of pulses of one millisecond duration programmed in regular and irregular sequences. The elicited sensations resembling vowels, fricatives, stops, ect., were readily learned because of their ease of association with already learned speech data. Subjective tests of this tactile communication indicated steep rates of learning and good retentivity. When appropriate phoneme-like sensations and silences were transmitted at about three frames/sec., the illusion of words was experienced which separated the communication from being simply a series of coded stimuli. This word-like, or Gestalt sensation is expected to increase in prominence as the tactile frame-rate is increased up to 10 frames/sec. Real-time speech-taction is anticipated as a future reality through use of an electrical analog of the human ear which would transduce speech to the tactile sensations already found to provide speech-like communication.
