Abstract
A method is provided for converting displayed text from one format to another. Text is input as handwriting in a pen-based computer and then automatically converted to a typeface text of a first text domain. Upon receipt of a conversion gesture that is recognized by the system as such, the system automatically converts the displayed text from the first text domain to a second character. The displayed text may be initially written as Hiragana and/or Katakana characters. Upon receipt of a conversion gesture, the system automatically converts the Hiragana and Katakana characters to appropriate Kanji characters.
Claims12
A method of converting characters from one text domain to another text domain in a stylus-based computer in which information may be entered by interaction of a stylus with a display screen, the method comprising the following steps:
- (a) identifying text that has been selected on the display screen;
- (b) determining whether the stylus has been used to enter a conversion gesture for converting the selected text on the display screen from a source text domain to a destination text domain;
- (c) determining the source text domain of the selected text;
- (d) determining an appropriate destination text domain to which the selected text is to be converted;
- and
- (e) replacing at least a portion of the selected text on the display screen with text from the destination text domain determined in step d, wherein the step of replacing at least a portion of the selected text on the display screen include the following steps:
- identifying a plurality of candidate text strings from the destination text domain;
- ranking those candidate text strings;
- and
- designating a top ranked candidate text string to be used in replacing the selected text.
A method of converting characters from one text domain to another text domain in a stylus-based computer in which information may be entered by interaction of a stylus with a display screen, the method comprising the following steps:
- (a) identifying selected text that has been delineated by a selection gesture input by the stylus on the display screen;
- (b) identifying a conversion gesture input by the stylus and having a bounding box overlapping a bounding box of the selected text on the display screen;
- (c) determining the source text domain of the selected text;
- (d) determining an appropriate destination text domain to which the selected text is to be converted;
- (e) identifying for the conversion one or more candidate text strings from the destination text domain;
- (f) ranking the one or more candidate text strings such that a single top ranked candidate is identified;
- and
- (g) replacing the selected text on the display screen with the top ranked candidate identified in step f.
