Designed for people with complex physical disabilities, the system is operated entirely with the eyes. By focusing on control keys displayed on the screen, a person can synthesize speech, control his environment (lights, appliances, etc.) type, run computer software, operate a computer mouse, and access the Internet and email.
The Eyegaze Communication System is an FDA- approved communication and control system for people with complex physical disabilities.
Eyegaze Communication System Overview
The Eyegaze Edge is an eye-operated communication and control system that empowers people with disabilities to communicate and interact with the world. By looking at control keys or cells displayed on a screen, a user can generate speech either by typing a message or selecting pre-programmed phrases. Eyegaze Edge Systems are being used to write books, attend school and enhance the quality of life of people with disabilities all over the world.
- Highly accurate – predicts a user’s gaze point to within 1/4 inch or less.
- Not tiring – programs & hardware are designed to reduce or eliminate visual fatigue associated with eye-controlled systems.
- Fastest input -activation time is user-determined and can respond in as little as 1/10 of a second.
- Comfortable – a user can operate from any position, including side-lying or with the head tilted, without tilting the screen.
- Works with most eye variations – including extremely large or small pupils, nystagmus, or irregularly shaped pupils.
- Handles ptosis (drooping) of the eyelid – entire pupil does not need to be visible.
- Adjustable camera – the Eyegaze Edge can be positioned high or low with a focus range of 16 inches to 30 inches.
- Works in low light – will even track mostuser’s eyes in the dark.
- Provides off angle tracking – the user does not need to be parallel to the screen.
- Tracks through lenses – works with eyeglasses and most contacts.
A specialized video camera mounted below the Eyegaze Edge screen observes one of the user’s eyes. Sophisticated image processing software in the system analyzes the camera’s images 60 times each second and determines where the user is looking on the screen. Nothing is attached to the user’s head or body.
A 15 second calibration procedure is required to set up the system for a particular user. To calibrate, the user looks at a small circles as it moves around the screen. There is no need to recalibrate if the user moves away from the screen and returns later.
A user operates 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 second, can be adjusted by the user. An array of menu keys and exit keys allow the user to navigate the Eyegaze programs independently.

EyeGaze Edge Testimonials
The Eyegaze System is a direct-select vision-controlled communication and control system. An Eyegaze user can perform a broad variety of functions including speech synthesis, environmental control (lights and appliances), typing, operating a television, and running both mouse- and keyboard-controlled applications on a second PC. Selections are made by looking at boxes or "keys" displayed on the Eyegaze System's screen. Nothing is attached to the user. Eyegaze programs vary from simple teaching programs, where the screen is divided into two or four large boxes (keys), to entire on-screen computer keyboards with 75 or more 5/8-inch square keys. Eyegaze users range in age from 5 years to 80 years old.
The Eyegaze System uses the pupil-center/corneal-reflection method to determine where the user is looking on the screen. An infrared-sensitive video camera, mounted beneath the System's monitor, takes 60 pictures per second of the user's eye. A low power, infrared light emitting diode (LED), mounted in the center of the camera's lens illuminates the eye. The LED reflects a small bit of light off the surface of the eye's cornea. The light also shines through the pupil and reflects off of the retina, the back surface of the eye, and causes the pupil to appear white. The bright-pupil effect enhances the camera's image of the pupil and makes it easier for the image processing functions to locate the center of the pupil. The computer calculates the person's gaze point, i.e., the coordinates of where he is looking on the screen, based on the relative positions of the pupil center and corneal reflection within the video image of the eye. Typically the Eyegaze System predicts the gaze point with an average accuracy of a quarter inch.
Eyegaze Edge Programs:
Main Menu appears on the screen as soon as the user completes a 15-second calibration procedure. The Main Menu presents a list of available Eyegaze Edge ® programs. The user calls up a desired program by looking at the eyegaze key next to his program choice.
The Phrases program, along with the speech synthesizer, provides quick communications for non-verbal users. Looking at a key causes a preprogrammed message to be spoken. The Phrases program stores up to 126 messages, which can be composed and easily changed to suit the user.
The Lights and Appliances program, which includes computer-controlled switching equipment, provides eyegaze control of lights and appliances anywhere in the home or office. No special house wiring is necessary. The user turns appliances on and off by looking at a bank of switches displayed on the screen.
The Computer Access Program permits the Eyegaze Edge ® to act as a peripheral keyboard and mouse interface to a Windows computer. The user can run any off-the-shelf software he chooses on the second computer. He can access the Internet and send e-mail by looking at keyboard and mouse control screens on the eyegaze monitor. The programs being run are displayed on the second computer’s monitor. Typed text appears simultaneously on the eyegaze monitor and the second PC’s screens.
Simple word processing can be done using the Keyboard program. The user types by looking at keys on visual keyboards. Four keyboard configurations, simple to complex, are available. Typed text appears on the screen above the keyboard display. The user may “speak” or print what he has typed. He may also store typed text in a file to be retrieved at a later time. The retrieved text may be verbalized, edited or printed.
Visually controlled Games include a Paddle game, Mahjong and Score Four.
The EyeMouse program makes it possible for a user to run off-the-shelf programs right on his Eyegaze Edge ®. By looking at off-screen keys, he can use his eyes for all standard mouse functions including left and right clicks, double clicks, and click and drag.
Simple EyeMouse is a single-click program that lets a child run programs such as Speaking Dynamically Pro™ or Clicker™ right on the Eyegaze screen.
Grid 2 Programs™:
Grid 2™ from Sensory Software adds another layer of functionality to the Eyegaze Edge®. The optional Grid 2 is fully integrated into the Edge and can be entered from the Eyegaze main menu.
Grids are available for adults and children, text-based or icon-based, and can be configured to suit the user.Grid Programs:
- Keyboard with speech
- Word processor
- Internet access
- Music and video player
- Basic calculator
- Skype, telephone, instant messaging, television control (available within the program, but supported by Sensory Software)
