ABSTRACT:
A chordic keyboard system for communicating with a data processing system. The chordic keyboard system includes ergonomic features, i.e., a keyboard that is tilted and an integrated palm rest. The chordic keyboard system also includes data entry features, i.e., storage for data representative of a plurality of chords, each chord corresponding to a subset of the plurality of keys of the chordic keyboard, and for a plurality of symbols, each data representative of a chord represented by and corresponding to one of the plurality of symbols according to a frequency-of-use index of the symbol and further according to a correlation based on a chord-difficulty index of the chord. The plurality of groups includes an alphabetic group, a punctuation/cursor control group, an editing/control function group, a numerical/mathematical group, and a punctuation/symbolic-type group. The chordic keyboard system also includes means for receiving data from the chordic keyboard identifying a selected chord of the plurality of chords, means for identifying, using the stored data and symbols, the group corresponding to the selected chord, and for identifying a selected symbol of the plurality of symbols representative of the selected chord, and means for generating a signal corresponding to the selected symbol.
