Conclusion

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, ALS, multiple sclerosis, brainstem strokes

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

6. How does eye gaze system works
A specialized video camera mounted below the monitor observe’s one of the user’s eye.
Sophisticated image processing software in the eye gaze system’s computer continually analyzes the video image of the eye.

7. Software & hardware requirements

.Keyboard
.Games .Read Text .Teach .Settings Program
Hardware
.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

8. How to run the Eyegaze System
A user operates the Eyegaze System by looking at rectangular keys that are displayed on the control screen.
To "press" an Eyegaze key, the user looks at the key for a specified period of time.

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. 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

19. Some of the common eye movement problems that interfere with Eyegaze use are
Nystagmus - constant, involuntary movement of the eyeball
Alternating strabismus - eyes cannot be directed to the same object,
either one deviates
The common vision problems are:
Inadequate Visual acuity
Diplopia (double vision)
Blurred vision
Cataracts (clouding of the
lens of the eye)

20. APPLICATIONS Neurosciences /Neuropsychology Vision Research

21. 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.
