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 Eyegaze, a communication & control system you run with your eyes In humans, gaze direction and ocular behaviour is probably one of the first distant means of communication developed. Parents often try to understand what their baby looks at, and they deduce that the object observed attracts his/her interest. This ability to interact with someone by a transitional object is named joint attention The Eyegaze System is a direct-select vision-controlled communication and control system. It was developed in Fairfax, Virginia, by LC Technologies.

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 theuser
Good control of one eye
 Adequate vision
Ability to maintain a position in front
of the Eye gaze monitor
Mental abilities

6. Software requirements
Software Programs
◦Main Menu
◦Games
Read Text
Teach
Settings Program


7. hardware requirements
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. Working Of The Eye Gaze System

9. 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

10. APPLICATIONS
Neuroscience/Neuropsychology
Vision Research
Experimental Psychology
Cognitive Psychology
Psycholinguistics
Psychiatry/Mental Health
Robotics-remote vision control

11. 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

12. 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.

13. 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.
