Abstract
Abstract An input system for Sino-computer characterized by dividing the Chinese characters into six basic strokes, i.e. horizontal, vertical, dot, dash, clockwise and counterclockwise, and giving each kind of stroke a corresponding designated numerical symbol, thereby, according to the exact stroke writing sequence of any character to give each character a spelling number to represent the character, to facilitate and simplify the input operation.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
113 words
A method of entering Chinese characters into an input system of a Sino-Computer, comprising: dividing each Chinese character into six basic strokes, said strokes including horizontal, vertical, dot, dash strokes and clockwise strokes and counterclockwise strokes, assigning each of said strokes a numerical equivalent, and entering said numerical equivalent into said input system in an order determined by the sequence in which said strokes appear in the respective character, said order being first from up to down and then from left to right, and with clockwise and counter-clockwise strokes having more than two segments, affixing to its respective numerical equivalent a sub-symbol corresponding to the clockwise and counter-clockwise direction of the segment, respectively.
Claim 2
Independent Claim
113 words
A method of entering Chinese characters into an input system of a Sino-Computer, comprising: dividing each Chinese character into six basic strokes, said strokes including horizontal, vertical, dot, dash strokes and clockwise strokes and counterclockwise strokes, assigning each of said strokes a numerical equivalent, and entering said numerical equivalent into said input system in an order determined by the sequence in which said strokes appear in the respective character, said order being first from up to down and then from left to right, and with clockwise and counter-clockwise strokes having more than two segments, affixing to its respective numerical equivalent a sub-symbol corresponding to the clockwise and counter-clockwise direction of the segment, respectively.
Claim 3
Dependent Claim
29 words
A method according to claim 1, wherein the numerical equivalent of said horizontal, vertical, dot, dash, clockwise and counter-clockwise strokes is 1, 2, 3, 4, 5 and 6, respectively.
Claim 4
Dependent Claim
49 words
A method according to claim 2, wherein when said clockwise stroke has more than two segments, affixing at the corresponding numerical equivalent of "5" a sub-symbol selected from the group consisting of "5" and "6" corresponding to the respective clockwise and counter-clockwise direction of the second and third segments.
Claim 5
Dependent Claim
49 words
A method according to claim 2, wherein when said counter-clockwise stroke has more than two segments, affixing at the corresponding numerical equivalent of "6" a sub-symbol selected from the group consisting of "5" and "6" corresponding to the respective clockwise and counter-clockwise direction of the second and third segments.
