It is now possible to design real-time, low-cost computer vision systems even in personal computers due to the recent advances in electronics and computer industry. Due to this reason, it is feasible to develop computer vision based human-computer interaction systems. In this paper, a vision-based continuous Grafiti T M -like text entry system is presented. The user sketches characters in a Grafiti T M -like alphabet in a continuous manner on a flat surface using a laser pointer. The beam of
