Incremental ideographic character input method
First Claim
1. Apparatus for incremental recognition of ideographic handwriting comprising:
- an input device for entering strokes of an ideographic character in natural stroke order;
an incremental character recognizer coupled to said an input device, responsive to each one of said strokes, that generates an hypothesis list of at least one candidate character containing said strokes which have been entered;
means for displaying said hypothesis list;
means for selecting a correct character from among said at least one candidate character of said hypothesis list; and
means for providing at least one additional individual stroke of said ideographic character in natural stroke order to said incremental character recognizer if none of said at least one candidate character of said hypothesis list have been selected.

Abstract
A method for incremental recognition of ideographic handwriting comprises in order the steps of: (1) entering in a natural stroke order at least one stroke of an ideographic character from a computer entry tablet; (2) providing the at least one stroke to an incremental character recognizer, which produces a hypothesis list of at least one candidate character; (3) displaying a hypothesis list of candidate characters containing the at least one stroke; (4) selecting a correct character from among the candidate characters on the hypothesis list if it a correct character appears thereon; (5) entering in natural stroke order at least one additional stroke of the ideographic character from the computer entry tablet if no candidate character is a correct character; (6) providing the additional stroke(s) to the incremental character recognizer, which produces an updated hypothesis list; (7) displaying the updated hypothesis list of candidate characters containing every stroke; (8) selecting a correct character from among the candidate characters on the updated hypothesis list if it a correct character appears thereon; and (9) repeating steps (5) through (8) until a correct character is selected from the updated hypothesis list.

10. An apparatus for the incremental recognition of ideographic characters, comprising
an input device for the input of coordinate data representing strokes of an ideographic character: -
an input processor for the processing of said coordinate data; an incremental recognizer that responds to each one of said strokes and generates a hypothesis list of at least one candidate character; and a display device having a first region for displaying strokes and a second region for displaying said at least one candidate character. - View Dependent Claims (11, 12, 13, 14, 15, 16)

17. A method for incremental recognition of ideographic handwriting comprising in order the steps of:
-
(1) entering at least one stroke of an ideographic character from a computer entry tablet; (2) providing said at least one stroke to an incremental character recognizer including a pre-processor and a statistical pattern classifier, said incremental recognizer producing a hypothesis list of at least one candidate character; (3) displaying said hypothesis list of candidate characters containing said at least one stroke; (4) selecting a correct character from among said candidate characters on said hypothesis list if it a correct character appears thereon; (5) entering at least one additional stroke of said ideographic character from said computer entry tablet if no candidate character is a correct character; (6) providing said at least one additional stroke to said incremental character recognizer and producing an updated hypothesis list of at least one candidate character; (7) displaying said updated hypothesis list of candidate characters containing every stroke; (8) selecting a correct character from among said candidate characters on said updated hypothesis list if it a correct character appears thereon; and (9) repeating steps (5) through (8) until a correct character is selected from said updated hypothesis list. - View Dependent Claims (18, 19, 20, 21, 22, 23)

24. A method for incremental recognition of ideographic handwriting comprising in order the steps of:
-
(1) entering at least one stroke of an ideographic character in natural stroke order from a computer entry tablet; (2) providing said at least one stroke to an incremental character recognizer including a pre-processor and a statistical pattern classifier, said incremental recognizer producing a hypothesis list of at least one candidate character; (3) displaying said hypothesis list of candidate characters containing said at least one stroke; (4) selecting a correct character from among said candidate characters on said hypothesis list if it a correct character appears thereon; (5) entering at least one additional stroke of said ideographic character in natural stroke order from said computer entry tablet if no candidate character is a correct character; (6) providing said at least one additional stroke to said incremental character recognizer and producing an updated hypothesis list of at least one candidate character; (7) displaying said updated hypothesis list of candidate characters containing every stroke; (8) selecting a correct character from among said candidate characters on said updated hypothesis list if it a correct character appears thereon; and (9) repeating steps (5) through (8) until a correct character is selected from said updated hypothesis list.
