ABSTRACT:
A continuous touch keyboard usable on a computer terminal, word processor or typewriter and configured to contain fourteen three-way switches, two for each thumb, one for each finger and one under each palm rest. The design is such that the hands and fingers do not need to move about to enter data, the keys being actuated by moving the fingers palmward, outward or pressing down and with equivalent motions of the thumbs and palms. Each switch controls the format of a signal from an emitter via optical fiber to a decoder. A microprocessor provides a digital scanning means and interprets or decodes the proper key position and thus the letter, numeral or function being entered.
