1. ABSTRACT
The Eye gaze System is a communication and control system for people with complex physical disabilities. You run the system with your eyes. By looking at control keys displayed on a screen, a person can synthesize speech, control his environment (lights, appliances, etc.), type, operate a telephone, run computer software, operate a computer mouse, and access the Internet and e-mail. Eye gaze Systems are being used to write books, attend school and enhance the quality of life of people with disabilities all over the world. Imagine yourself being a intelligent, motivated, and working person in the fiercely competitive market of information technology, but just one problem You can't use your hands. Or you can't speak. How do you do your job? How do you stay employed? You can, because of a very good gift from computer Industry: The Eye gaze, a communication & control system you run with your eyes. The Eye gaze System is a direct-select vision-controlled communication and control system. It was developed in Fairfax, Virginia, by LC Technologies, Inc.,

2. THE SKILLS NEEDED BY THE USER
This system is mainly developed for those who lack the use of their hands or voice. Only requirements to operate the Eye gaze are control of at least one eye with good vision & ability to keep head fairly still. Eye gaze Systems are in use around the world.  Its users are adults and children with cerebral palsy, spinal cord injuries, brain injuries, ALS, multiple sclerosis, brainstem strokes, muscular dystrophy, and WerdnigHoffman syndrome.  Eye gaze Systems are being used in homes, offices, schools, hospitals, and longterm care facilities. By looking at control keys displayed on a screen, a person can synthesize speech, control his environment (lights, appliances, etc.), type, operate a telephone, run computer software, operate a computer mouse, and access the Internet and e-mail. Eye gaze Systems are being used to write books, attend school and enhance the quality of life of people with disabilities all over the world.

Figure: An example of fixations and saccades over text. This is the typical pattern of eye movement during reading. The eyes never move smoothly over still text. 3. HOW DOES THE EYEGAZE SYSTEM WORKS

For using the Eye gaze Systems the users sits in front of the system’s screen and for tracking the eye movement of the user the systems follows the below mentioned steps. As the system starts tracking the movement of the eyes, all the features of the system can be used depending on the requirements. As a user sits in front of the Eye gaze monitor, a specialized video camera mounted below the monitor observes one of the user's eyes.  Sophisticated image processing software in the Eye gaze System's computer continually analyzes the video image of the eye and determines where the user is looking on the screen.  Nothing is attached to the user's head or body.
