Abstract (in Japanese) (See Japanese page) 
(in English) An on-line handwritten character recognition technique based on a new HMM is proposed. In the proposed HMM, not only pen-direction features but also pen-coordinate features are utilized for describing the shape variation of on-line characters more accurately than conventional HMM where the pen-coordinate features are not utilized because of their non-stationarity. Specifically speaking, the proposed HMM outputs a pen-coordinate feature at each inter-state transition and outputs a pen-direction feature at each intra-state transition, i.e.,self-loop. Thus, each state of the proposed HMM can specify the starting position and the direction of a line segment by its incoming inter-state transition and intra-state transition, respectively. The results of recognition experiments on 10-stroke Chinese characters show that the proposed HMM outperforms conventional HMMs.
