  • Patent number: 4379288
    Abstract: A word processing system for Chinese type characters includes a keyboard with a generally standard key arrangement for encoding the characters in accordance with their basic stroke type and sequence. Up to eight basic stroke types may be employed, although a five stroke system is preferred. Recurrent code sequences of two, three, four and five strokes are identified. An "end of character" code may be generated with the space bar. Preferred sequences are assigned key positions so as to provide an ergonometrically efficient keyboard. Average typing speeds using the keyboard are comparable on a character/word basis to those for English.
