Abstract

PURPOSE: To obtain ease of writing symbol by simplifying the pattern recognition means, by one writing consisting of straight lines for the symbols being the objective of recognition, and drawing it with the same direction as either one of several fundamental direction vectors for each line.
CONSTITUTION: One set of pattern data such as one to three writing symbols are assigned to all the pattern recognsition collating symbols, and the writing direction information of straight lines constituting the symbols is stored in the memory unit of the control processing unit 3 according to the order of writing. Based on the locus of the stylus 2 drawn on the tablet 1, the corresponding pattern stored to the control processing unit 3 is selected and the pattern selected is processed. The direction of significance of a plurality of straight lines of the symbol is set to directions 1W8, one of eight lines is drawn to the same direction as the reference vector, and while the stylus 2 is in contact with the tablet 1, the pattern can be identified as the unit command.
