Motion analysis of hand writing Japanese character using human computer interface

A brush pen is one of traditional writing tools, and it is used to practice the writing characters in schools. Handwriting with the brush pen requires some basic skills for pupils and students. For example, they must keep speed of the brush pen while drawing strokes. In order to support hand writing practice, motion analysis of the written character is necessary. In this paper, we developed a new human-computer interface for hand writing character that uses ordinal papers and brush pen. Strokes written by the brush pen can be inputted into a computer by using a CCD camera. And the strokes written by the brush pen can be reconstructed and displayed as a character on the computer display at the realistic rate. We developed an algorithm to evaluate the character.
