An Overview of “Electrooculography”

Abstract: This paper brings out a new technology of placing electrodes on user’s forehead around the eyes to record eye movements which is called as Electrooculography (EOG. This technology is based on the principle of recording the polarization potential or corneal-retinal potential (CRP), which is the resting potential between the cornea and the retina. This potential is commonly known as electrooculogram. is a very small electrical potential that can be detected using electrodes which is linearly proportional to eye displacement. EOG serves as a means of control for allowing the handicapped, especially those with only eye-motor coordination, to live more independent lives. This is a low cost assistive system for disabled people. The total command control based on EOG permits users to guide it with a enough degree of comfort ability.
