Electrooculogram Based Online Control Signal Generation for Wheelchair

Abstract

Human computer interfacing technology has paved a new way in providing services to people with special needs (i.e., elderly, people with impairments, or people with disabilities). Research is going on to interface the movement based biosignals with machines. Electrooculogram is the signal produced due to eye ball movements and can be used to control mobility aids. Electrooculogram is the potential difference around the eyes due to movement of the eye balls in different directions. In this study an acquisition system for electrooculogram is designed to collect the desired signal with low noise and then signal processing is done for control application. The contribution of this paper lies in the development of two new strategies of electrooculographic signal based control of motors in real time.
