Abstract: We present a computer vision based text and equation editor for LATEX. The user writes text and equations on paper and a camera attached to a computer records the actions of the user. In particular, positions of the pen-tip in consecutive image frames are detected. Next, directional and positional information about characters are calculated using these positions. Then, this information is used for on-line character classification. After characters and symbols are found, the corresponding LATEX code is generated.
