THE PRINCIPLES OF ONLINE HANDSKETCH INPUT

This paper makes a deep research to the human factor aspect in manma-chine interactions by application engineers. Using the research as a basis,the authors develop a online handsketch input system. We developed a "Handsketch Recognition and Input System "which can directly display engineer's thinking on the screen,the input speeds are very fast,their errors are more fewer. This paper mainly introduces the recognition principle of the system.
