BY CH.RAJITHA INTRODUCTION Communication System For Disabled Controlled System Direct-select Method Vision-controlled Communication System. Who are the users of this eye gaze communication system? Lack Of Hands Or Voice Cerebral Palsy Spinal Cord Injuries Brain Injuries 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 Mental abilities . PARTS OF THE EYE GAZE SYSTEM GOOD CONROL OF ONE EYE MONITOR SCREEN EYE GAZE CONTROL MONITOR MONITOR TRAY AND ARM VIDEO CAMERA LED CAMERA LENS AND BRACKET . WORKING OF THE EYE GAZE SYSTEM . How can we run this eye gaze system? . .THE MAIN MENU The Main Menu appears on the screen as soon as the user completes a 15-second calibration procedure. provides quick communications for nonverbal users.THE PHRASE PROGRAM The Phrase program. The Phrases program stores up to 126 messages. which can be composed and easily changed to suit the user. . along with the speech synthesizer. THE TELEPHONE PROGRAM Non-verbal users may access the speech synthesizer to talk on the phone . RUN SECOND PC As a keyboard . As a mouse controller . THE LIGHTS & APPLIANCES PROGRAM . With Options Of The Eye Gaze A User Can: BE AT TWO SITES!! BE A KEYBOARD SPEAK through a speech synthesizer CONTROL appliances DIAL and answer a phone . GAMES: Play games. READ TEXT: Turn pages on the computer screen by looking at "up" or "down". then print or speak. . plus Solitaire and Slot Machine.A Basic Eye gaze can: CALIBRATION: Adjust to a new user in about 15 seconds. TEACH SCREENS: Teach new users with simplified screens. two "Paddle" games. TYPEWRITER: Type with one of four keyboards. The System works best away from windows. which are low in infrared. and in a room lit with fluorescent or mercuryvapor lights.OPERATIONAL ENVIRONMENT The Eye gaze System must be operated in an environment infrared light. . very sophisticated image processing and calibration methods .IntelliGaze IG-30 It is a sophisticated system with a high tracking rate and excellent working range. It can accommodate rapid or involuntary head movements Intelligaze uses the latest camera technology. It helps the user to answer/dial a call It helps the user to operate his environment. . The user can be a keyboard/mouse and operate a system.ADVANTAGES It helps the user to generate text on a computer. Can construct words and sentences that can be spoken aloud by the system. .DISADVANTAGES The high cost of eye tracking equipment The limitation that gaze communication applications may only work with a particular dedicated eye tracking device Finally that eye tracking devices are often hard to use and require experts to operate them. remote vision control •Video and arcade games .APPLICATIONS •Neurosciences /Neuropsychology •Vision Research •Experimental Psychology •Cognitive Psychology •Psycholinguistics •Psychiatry /Mental Health •Robotics . 0 •Totally Free Head Motion •Automatic Eye Acquisition •Binocular Eye tracking •High Gaze point Tracking •Accuracy •Easy User Calibration .FUTURE WORK The Eye gaze System’s Eyefollower2.

Establishing an Encoded Eye Gaze Communication System. CONCLUSION The main reason for eye-gaze based user interfaces being attractive is that the direction of the eye-gaze can express the interests of the user-it is a potential porthole into the current cognitive processes-and communication through the direction of the eyes is faster than any other mode of human communication.
