An extended Eye Movement Tracker system for an electric wheelchair movement control

To compensate the incapability of severely disabled person, intelligent wheelchairs are commonly adopted using several non manual command techniques. Eye tracking is one of such techniques. Although it has been the subject of intense research for many years, Eye tracking has not yet reached the level of perfection to be commercially used in an intelligent wheelchair to control electrical powered wheelchairs (EPW). This paper presents an eye tracking system based on fuzzy logic controller to control an EPW with a simple web cam placed in front of the user. Simulation results indicate that the fuzzy logic controller gives better results compared to other techniques.
