Eye-gesture controlled intelligent wheelchair using Electro-Oculography

This paper describes the design and implementation of an eye-gesture controlled electric wheelchair using the technique of Electro-Oculography. This is designed to be used as an intelligent mobility aid for the paralyzed, which has features such as tilt detection, obstacle sensing, avoidance and path re-routing. The design employs an embedded control module that processes the bio-electric signals generated by the eye movements to actuate real world events. A microcontroller is used in place of a laptop computer, as the decision making entity, thereby making this an affordable solution. Various safety features are integrated using the control module to make a robust and optimized model.
