Description

This paper describes the design of user interfaces(UI), and pattern processing and recognition methods for an on-line recognition system "METAH" for the input of mathematical expressions by handwriting. Mathematical expressions possess geometrical information that expresses their structures. Handwriting is thus suitable for inputting such objects. However, pattern recognition entails misrecognition and rejection. Well designed UI's are as essential to the system as high recognition rates. Based on the fact that handwriting does not interrupt creative thinking, this paper presents UI's for the creative input of mathematical expressions. In contrast to the creative input, the design of UI's for their copy input is also discussed. As for the recognition processing, the prototype system partitions mathematical expressions into symbol patterns, identifies each symbol, recognizes their positional relationships and then parses them.
