On-Line Recognition of Mathematical Expressions Using Automatic Rewriting Method

Abstract. This paper describes our system of on-line recognition of mathematical expressions. Users can input mathematical expressions by handwriting. As soon as a character is written, it is rewritten by neat strokes in an appropriate position and size automatically. This Automatic Rewriting Method improves the accuracy of the structure analysis of the written mathematical expressions. The written mathematical expressions can be output into files in the notation of LATEX and MathML. By this handwriting interface, the system realizes a very easy intuitive methods to input mathematical expressions into computer.
