Conclusion
Slide3The 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.
Introduction
Slide4Users Of Eye Gaze SystemThis 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
Slide5Skills needed by the users Good control of one eye
Adequate vision Ability to maintain a position in front of the Eye gaze monitor memory
Slide6How does eye gaze system worksA 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.

Slide8How 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.

Slide14Operational 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.
Slide15Intelli Gaze IG-30It is a sophisticated system with a high tracking rate and excellent working range.
It can accommodate rapid or involuntary head movementsIntelli Gaze uses the latest camera technology, very sophisticated image processing and calibration methods

Slide19Some 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 acuityDiplopia
(double vision) Blurred visionCataracts (clouding of the
lens of the eye)
Slide20APPLICATIONS Neurosciences /Neuropsychology

Robotics - remote vision controlVideo and arcade games
Slide21CONCLUSION
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.
