EyeGaze Edge Eye-tracking Technology

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.

With the Eyegaze Edge system a user can:

  • Operated lights and appliances remotely

  • Control infrared devices such as televisions and stereos

  • Wirelessly control their own PC or Mac, using the Computer Access program’s on-screen keyboard and mouse

  • Surf the Web and send emails

  • Store and play music

  • Organise photos and home movies and view them

  • Read books in Kindle

  • Watch YouTube videos

  • Use a word processor

  • Update their Facebook Page

How the eye-tracking device works

A specialised video camera mounted below the Eyegaze Edge screen observes one of the user’s eyes. Sophisticated image processing software in the system analyses 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.



The Eyegaze programs have many adjustable parameters. The gaze duration, phrases and appliance labels, for example, can all be easily changed. An assistant or caregiver may edit the text or change data values through the ECS Settings program. The optional Grid 3 program enables the user to create his own custom communication screens, which can be stored for continued use. Grids can be designed with pictures or text with any sized cell and offers features such as Kindle, Facebook, Internet and television control.
