Data Acquisition System of Electrooculogram

The main aim of the project is to capture the natural movement of eye and applying it as an aiding application to mute or paralyzed patients. In order to accomplish the development of this aid, Electrooculography method is applied. An Electrooculography is a method based on observing the eye movements also called as ocular movements. The Voltages are acquired as output based on the changes in the orientation of eye. The difference in voltage levels obtained are divided into four different ocular movements. They are Saccade movement, Smooth-pursuit movements, Vergence movements, Vestibulo ocular movements described in the later sections The EOG acquisition system for detecting eye movements that is able to restore communication abilities to patients who have nonfunctional limbs and facial muscles has been developed and an accuracy of 78% has been achieved.
