found the following some stable features . (1)The same blind person can write almost the same stroke shape, stroke number and stroke writing order. (2)The relative position of the stroke representative points in the partial pattern is stable. Two kinds of character recognition algorithm; namely, the RDS method and the LSDS method have been proposed for this system by using the above features. The RDS method is based on the relative direction between two strokes in a writing order. We represent each stroke of the Kanji character by three typical points (a starting point, a middle point and an ending point). This recognition method is called the LSDS method (the method based on the line segment directions in a stroke) in this paper. A stroke is divided into several line segments by the same segment length. A feature parameter set is expressed as a set of eight direction codes that correspond to each line segment. The combination of the two methods is desirable to recognize all type of Japanese character written by the blind person, because these methods use different type feature. This method is named the fusion method in this paper. 3.2 ERROR CORRECTION METHOD From recognition experimental result, it was difficult to distinguish similar characters to use the fusion method that is the recognition algorithm for the one character order. Therefore we adapt the two error correction methods
