Meet 5 Eyegaze Edge Users

From walking and driving to things we take for granted, like eating and entertaining ourselves, people with disabilities face challenges every day. Technology like our Eyegaze Edge can help people meet these challenges head-on. The Eyegaze Edge, an eye-controlled communication and control system, uses the pupil-center/corneal-reflection method to determine where the user is looking on the screen.

Here’s how the EyeGaze Edge eye-tracking works:

An infrared-sensitive video camera, mounted beneath the system’s screen, 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 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 so the system’s image processing functions can accurately locate the center of the pupil.

This fascinating technology is changing the lives of our users, including those below:


I used my Eyegaze to do the Internet, email, Facebook, and schoolwork. I do algebra, spelling, social studies, and English work at school and at home. When I was sick in the hospital, I told the doctors and nurses what I needed by using my Eyegaze because I couldn’t talk when I had a breathing tube. I’m using my Eyegaze to write this story about how I use my Eyegaze!


My arms and hands were deteriorating quite rapidly, meaning I couldn’t work anymore. The Eyegaze saved my software engineering job. I can control a Mac and do everything with my eye that I used to do with my hands. I can respond to email, I can program, I can control debuggers, I can surf the web, and I can hold conversations, not fast but with practice I’ll get faster.”


Liam is one of our youngest Eyegaze users. He was able to run the system with only his eyes before the age of two. The flexibility of the Eyegaze Edge allows him to operate the system from any position.

Joe was an early Eyegaze user. As senior vice president of Nations Bank, he participated in merger negations via email written with his Eyegaze system. After retiring from the bank, he went on to write and publish two books.


Cassandra, who has cerebral palsy, has been an Eyegaze user since she was 8 years old. Now in her mid-twenties, she owns her 3rd Eyegaze system. She has used her systems throughout her entire education.

Nancy Cleveland is a nurse who has spent 30 years traveling around the world introducing people with severe disabilities to Eyegaze technology. Thanks to this technology they’re doing some amazing things with their lives. Hear the inspiring stories of what can be accomplished when all you’ve got is the use of your eyes.
