%X In order to make the guidance more objective on users' handwriting, which was from the online writing guidance system, and for non-standard writing behavior, touch writing noise was divided into white, black and shake. The correspon-ding processing methods included linear interpolation to eliminate white noise, threshold duplicate removed to eliminate black noise, and virtual smooth based on key point calculation to eliminate shake noise. The test result shows that this method provides a real, valid and reliable data environment for writing guidance system in real-time analysis.
