An Eye Movement Tracking System

In this paper, we proposed an eye-movement tracking system. Based on Electro-Oculography (E.O.G) technology we detected the signal with different directions in eye-movements and then analyzed to understand what they represented about (e.g. horizontal direction or vertical direction). This enables people to control applications using bio-electric signals recorded from the body. In an Electrooculogram (EOG) based, signals during various eye (cornea) movements are employed to generate control signals. Electrooculography is a technique for measuring the resting potential of the retina. The resulting signal is called the electrooculogram. Moreover, it is simpler to complete the feature extraction and analysis of EOG signals. So, it will achieve more success to design of wheelchair guidance by EOG.

I. INTRODUCTION
W heelchairs are important mobile aids for elders and disabled patients. Electrooculography is a technique for measuring the resting potential of the retina. The resulting signal is called the electrooculogram. This paper has investigated that different EOG signals obtained from four different places around eye; (right, left, up, and down) have led to different level of distance and rotation of wheelchair. Those four signals are correspond to different levels of right and left steer, forward and backward motion. EOG controlled device are gaining popularity in recent
