2. Abstract
•The Eye gaze System is a communication
system for people with complex physical
disabilities.
•This operates with eyes by looking at
control keys displayed on a screen.
•With this system a person can synthesize
speech, control his environment , operate
a telephone, run computer software,
operate a computer mouse, and access
the Internet and e-mail.

4. Introduction
• The Eye gaze System is a direct-select vision-
controlled communication and control system.
• Edmund Huey built an early
eye tracker, using a sort of
contact lens with a hole for
the pupil. The lens was
connected to an aluminum
pointer that moved in
response to the movement of
the eye

5. •It was developed in Fairfax, Virginia, by LC
Technologies, Inc.,
•With the help of an eye gaze system,
people whose communication abilities are
impaired can still express their feelings and
needs with a limitless vocabulary.

6. Who uses the eye gaze
system?

7. •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

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

9. Parts of the eye gaze system

10. Working of the eye gaze system

11. How can we run this
eye gaze?

12. •Calibrate
•Typewrite
•Read Text
•Entertain with
games
•Teach Screens
The Basic Eye gaze can

13. With Options The Eye gaze Can
•BE AT TWO SITES!!
•BE A KEYBOARD
•SPEAK through a speech synthesizer
•CONTROL appliances
•DIAL and answer a phone

15. The Phrase Program

16. The telephone program

17. As a mouse controller

18. The Lights & appliances Program

19. Operational environment
•The Eyegaze 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.

20. SOME OF THE PRESENT DAY EYE GAZE
TRACKING TECHNIQUES
•Offer an unobstructed field of view with good
access to the face and head.
•Make no contact with the subject.
•Be easily extended to binocular recording
•Be compatible with head and body recordings
•Be easy to use on a variety of subjects.

21. Advancements
•New portable eye gaze systems

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

23. For people with limited eye control
Scanning Keyboard is the new row/column
keyboard with an on- screen eye "switch" for
people with limited eye movement.

24. Mental abilities that improve the
probability for successful Eyegaze use
•Ability to read
•Cognition
•Memory

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

26. FUTURE WORK
•Totally Free Head Motion
•Automatic Eye Acquisition
•Binocular Eye tracking
•High Gaze point Tracking Accuracy
•Easy User Calibration

27. 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.
•Care must be taken, though, that eye-gaze tracking
data is used in a sensible way, since the nature of
human eye-movements is a combination of several
voluntary and involuntary cognitive processes.
