Eye mouse controlled using electroculogram

Abstract

Paralysis is one amongst the major neural disorder that causes loss of motion of one or more muscles of the body, where in depending on the cause, it may affect a specific muscle group or region of the body. Eye movement can be used by the paralysis patients and armless persons to perform simple tasks. This paper presents an implementation of a low-cost aid for severely disabled persons to communicate with computer directly by physical means. The communication is done through Electro Occulo Gram (EOG) signals generated by the movement of eyes. The blink, left & right commands are used to communicate with computer. The retinal resting potential causes an electric field Around the eyeball, centred on the optical axis, which can be Measured by placing electrodes near to the eye. An acquisition System and a lab view application were implemented for Measuring these bio potentials in order to detect the movement of the eyes.
