The invention discloses a hand-written character input method, which comprises: A, ,performing feature selection on prestored character classes and calculating a template in coarse classification; B, performing feature transformation on the prestored character classes and calculating a template in fine classification; C, acquiring a discrete coordinate sequence of a track point of an input character and adopting a smooth continuous function to adjust the size and shape of the hand-written input character and a centrobaric coordinate value; D, extracting feature to obtain a multidimensional feature vector of the hand-written character; E, selecting partial feature value of the hand-written input character, matching the hand-written input character with the template in coarse classificationrespectively, and selecting a plurality of candidate character classes with the maximum similarity; and F, performing feature transformation on the hand-written input character, matching the hand-written input character with the sample center of the candidate character classes selected from the template in fine classification, and determining the most similar character classes. The invention alsodiscloses a hand-written character input system. The invention has higher speed of identifying the hand-written input character, and higher identification accuracy.
