3. Introduction
The Eye gaze System is a communication and control system for people with complex physical disabilities.
The Eye gaze System is a direct-select vision controlled communication and control system.

4. Users Of Eye Gaze System
This system is mainly developed for those who lack the use of their hands or voice
Its users are adults and children with cerebral palsy, spinal cord injuries, brain injuries, multiple sclerosis, brainstem strokes

5. Skills needed by the user
Good control of one eye 
Adequate vision
Ability to maintain a position in front of the Eye gaze monitor
Mental abilities

6. Software & hardware requirements

.Desktop computer with OS
.CD and floppy drives .15" LCD Flat Panel Monitor .Adjustable monitor tray with camera bracket .High-speed infrared sensitive camera and lens

7. Working Of The Eye Gaze System

8. How does it work
The eye gaze system uses the pupil_ central corneal reflection method
Video camera mounted below the monitor ,it takes 60 pictures per seconds
Infra-red
•Reflected from eye
•Sensor records where the reflected light is moving
•computer calculate the persons gaze point

14. Operational Environment
The Eye gaze System must be
operated in an environment
where there is limited of
infrared light.
The System works best away
from windows, and in a room
lit with fluorescent or mercury-
vapor lights, which are low in
infrared.

15. Applications Neuroscience/Neuropsychology Vision Research
Experimental Psychology
Cognitive Psychology
Psycholinguistics
Psychiatry/Mental Health
Transportation: Flight simulators/driving simulators
Robotics-remote vision control
Video and arcade games

16. Advantages Eye movement is faster than other current input media
No training or particular coordination is required for normal users
Can determine where the user’s interest is focused automatically
Helpful for usability studies to understand users interact with their environment

17. Disadvantages The equipment is expensive
Some users can't work with the equipment (for example if they wear contact lenses or have long eye lashes)
Calibrating the equipment takes time; this problem may resultantly cause the user to deviate from using the device.

18. Latest potable Eye Gaze system

20. Intelli Gaze IG-30
It is a sophisticated system with a high tracking rate and excellent working range.
It can accommodate rapid or involuntary head movements
Intelli Gaze uses the latest camera technology, very sophisticated image processing and calibration methods

21. Images Of Eye Gaze Systems

22. CONCLUSION
Today, the human eye-gaze can be recorded by relatively unremarkable techniques. This thesis argues that it is possible to use the eye-gaze of a computer user in the interface to aid the control of the application.
