Abstract— This work presents a neoteric technology to assist disabled people, by tracking eye movement using low cost equipment. Eye tracking has been done using electrooculogram method (EOG), as opposed to traditional methods like video oculography, where a digital video camera is used to record the eye movement, and magnetic search coils, where three dimensional coils are used to track the eye movements. In EOG, the user's eye movement is tracked using a low cost electrode and the signals are suitably amplified and filtered to get a voltage. This is an elementary method to track the potential changes when the subject moves his eye and is a great help for the disabled to access control and communication devices. The design of the amplifier and filter is presented. Open source platforms processing 1.5.1 and arduino 1.0.3 are used for the implementation of the design. The experimental results are presented. It is found that the simple set up presented here, works accurately and can be used to control equipment using eye movement.

Index Terms— EOG, eye tracking, potential, disability.
