EYE-GAZE COMMUNICATION
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.
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
• 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.
Who uses the 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
Skills needed by the users
• Good control of one eye
• Adequate vision
• Ability to maintain a position in front of the Eye gaze monitor
How can we run this eye gaze?
The Basic Eye gaze can
• Calibrate
• Typewrite
• Read Text
• Entertain with games
• Teach Screens
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
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.
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.
