3. Abstract The objective of the Eye Gaze communication system is use the eye gaze of human for interaction with the computer. It will help the user to operate the computer based system by giving commands with the eyes. This system was developed for the people with complex physical disabilities, who were unable to use their body parts. This system improved the quality of life of these people. The main advantage of these system is that their is no need of physical connection between the user and the system. And the user can run the system with their eyes.

4. Introduction The Eye gaze is a communication & control system, we can run with our own eyes. It is a direct-select vision controlled communication system. It was first time introduced by Yarbus and known as Yarbus eye tracker in the 1960. Eye tracking is a process of measuring the point of gaze(where one is looking) or the motion of the eye relative to the head.

5. Users of Eye Gaze Communication System This system is mainly developed for those who is physically disable with their hands or voice. Its users are : Adults and children with cerebral palsy , spinal cord injuries , brain injuries , brainstem stroke , multiple sclerosis , muscular dystrophy and Werdnig –Hoffman.

7. Fields In Which It is Being Used Eye Gaze System is being used in homes , offices , schools , hospitals , and long –term care facilities. By looking at the control keys displayed on a screen , a person can easily synthesize speech control his environment , type operate a telephone , run computer software , operate a computer mouse and access the internet and emails.

8. Skills required by User Good control of one eye Adequate vision Ability to maintain a vision in front of the eye gaze mirror Mental ability : 1. Ability to read 2. Memory

9. Hardware Parts Required

10. Working A less than 15 second calibration procedure is required to set up the system for a particular user looks at a small calibration point as it moves around the system. A user operate the system by looking at rectangular “keys” or cells that are displayed on the control screen. To “press” a key the user looks at the key for a specified period of time. The gaze duration required to visually activate a key , typically about ½ seconds , can be adjusted by the user.

11. Configuration Detail This system is robust and extremely easy to calibrate. This system uses the Pupil – Center /Corneal Reflection method to determine the eye’s gaze direction. A video camera is located below the computer screen which is remotely observes the subject’s eye

12. Menu’s of Eye Gaze System The main appears on the screen as soon as the user completes its15 second calibration procedure. It is the list of available in the system. It contains – The Phase program The Type Writer Program The Telephone Program Run Second PC Paddle games and Score four Read Text Program Television

13. Main Menu Options The Phase Program It provide quick communication for non-verbal users. The phase program stores up to 126 messages which can be composed and easily used by the User.

14. The Typewriter program Simple word processing can be done by using the typewriter program. The user can type by looking at the keys on visual keyboard. The user may “speak” or print what he has typed. The Television Program A television can be directly displayed on the desktop of the system.

15. Run Second PC It permits system to act as a peripheral keyboard and mouse interface to a windows computer. Keyboard choices are same as the Typewriter’s. Read Text Program This program allows the user to select text for display . Frequency Keyboard

16. Light &Application Program It include computer controlled switching equipment, which provide eyegaze control of lights and appliances anywhere in the home or office . Paddle games and Score four These are the visually controlled games.

17. The Telephone Program The telephone program allows the user to place and receive calls. Frequently used numbers are stored in a Telephone Book. Non verbal user may access the speech synthesizer to talk on the phone.

18. 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

19. NEW PORTABLE EYE GAZE SYSTEMS The Portable Eye gaze System can be mounted on a wheelchair and run from a 12-volt battery or wall outlet . It weighs only 6 lbs (2.7 kg) and its dimensions are 2.5"x8"x9" (6.5cm x20cm x23cm). The Portable Eye gaze System comes with a flat screen monitor and a table mount for its monitor. The monitor can be lifted off the table mount and slipped into a wheelchair mount. Figure: Portable Eyegaze System Mounted on Wheelchair Figure: Screen of Eyegaze System

20. ENVIRONMENT REQUIRED FOR AN EYEGAZE SYSTEM Because eye tracking is done using infrared light. Eye gaze system must take care of light sources in the room in order to ensure the best accuracy. The Eye gaze System must be operated in an environment where there is limited of ambient infrared light. Common sources of infrared light are sunlight and incandescent light bulbs. The System makes its predictions based on the assumption that the only source of infrared light shining on the user's eye is coming from the center of the camera. Therefore, stray sources of infrared may degrade the accuracy or prevent Eye gaze operation altogether. The System works best away from windows, and in a room lit with fluorescent or mercury-vapor lights, which are low in infrared.

22. Limitations The equipment is expensive .(Even Google, which has all the money in the world, has only outfitted one of their many labs.) Some user 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.(Calibration is the process in which the eye tracker camera measures characteristics of the eye gaze direction) Requires Miniaturization (Miniaturization is the process of manufacture small Mechanical, Optic and Electronic Products and Devices.)Miniaturization not only increase Portability but improves Energy efficiency by reducing the Power requirement of the Eye -Gaze System .

23. CONCLUSION From this seminar session of various paper we conclude that using eye gaze as pointing tool to operate system is very useful .This paper argue that it is achievable to use eye gaze of computer user within interface to help management of application . As eye tracking system improve in quality and accuracy and reduce in value , it will grab attention of the user.
