Vibratese
Vibratese is a method of communication through touch. It was developed by F. A. Geldard, 1957. It is a tactile system based on both practical considerations and on results from a set of controlled psychophysical experiments. Vibratese was composed of 45 basic elements, the tactile equivalent of numerals and letters. The entire English alphabet and numerals 0 to 9 could be communicated this way. Geldard reported that with proper training, rates of more than 35 words per minute were possible for reading., Vibratese is no longer in use, with little literature available on the subject.
