A Study on Correction Functions for On-Line Handwriting Entry of Mathematical Formulas
This paper describes functions for correcting mathematical formulas inputted using the handwritten mathematicalformulaentrysystemthatwehaveproposed [8,9]. This system encourages intuitiveentries of mathematical formulasusing a user-friendlyhandwriting interface.We have implementedtwobasicoperationsspecializedforcorrecting formula structures. One of the operations is "move and resize" of selectedcharacters.This is because the position and the size of mathematicalsymbolsare quite importantto recognizingthemeaningsof formulas. Theother operation makes it possibleto select a block consistingof several characters and symbols. These two operations enablemore flexible and efficient correctionof the structureofthemathematicalformulas.Theexperimantalresults showedthat a user can easily and efficientlycorrectwrong formulas by using the proposed functions.
