Handwriting recognition by character template
First Claim
1. A method of data entry using a graphic input and display tablet and a character recognition system including the steps ofdisplaying a template which defines strokes which can be recognized by said character recognition system,inputting a locus on said graphic input and display tablet including a step of displaying said locus,determining that entry of said locus is complete,converting said locus to a glyph comprising one or more strokes of said template and displaying said strokes of said template corresponding to said locus while removing display of said locus,determining that entry of said glyph is complete, andgenerating a code corresponding to said one or more strokes in response to said step of determining said glyph is complete.

Abstract
A method for entry and recognition of elements from a set of symbols, involving a template of line segments displayed on an electronic writing surface. A stylus is applied to the electronic writing surface so as to trace a desired symbol. A computing arrangement is used to "snap" the strokes made by the stylus onto the corresponding template line segments. Upon completion of a symbol, a code is made to represent the line segments and this code is used to reference entries in a data structure to identify the appropriate corresponding computer code. If there is no match, the code for the line segments and a corresponding set of computer codes can be added to the table. This method takes advantage of natural handwriting skills and can be used for a variety of symbol sets.

11. A data entry arrangement using a graphic input and display tablet and a character recognition system including
means for displaying a template which defines strokes which can be recognized by said character recognition system, means for inputting a locus on said graphic input and display tablet including means for displaying said locus, means for determining that entry of said locus is complete, means for converting said locus to a glyph comprising one or more strokes of said template, including means for displaying said strokes of said template corresponding to said locus and removing display of said locus, means for determining that entry of said glyph is complete, and means for generating a code corresponding to said one or more strokes displayed and corresponding to said locus responsive to said means for determining that entry of said glyph is complete.
