In this paper, we propose a new practical user interface to input mathematical expressions into computer, using a data tablet or an electron board. The system recognizes mathematical expressions of high school level (until the first year of university), and the results are output in L A T E X-source format.For the character recognition, we use 3 _ 5-mesh directional element feature and some additional features which are robust against the distortion. As for the segmentation of characters and the structure analysis of mathematical expressions, our method is considerably robust against the touching of characters and the deviation of positions in the wide range.
