Eyes Have Control: Eye-Tracking Technology Lets Disabled Communicate with PCs

By Barnes, Peter; ABC News.com,
Publication Date: July 2002

Article discussing the Eyegaze Computer System, and how it facilitates communication for people with disabilities. The Eyegaze System utilizes a video camera placed under a computer monitor, which is equipped with an infrared light-emitting diode (LED). The LED bounces light from the user’s cornea and retina. The camera records the reflections and sends the signals to proprietary software, which moves the cursor to the spot the user is looking at. The user is presented with the letters of the alphabet, along with punctuation symbols and commands lined up on the computer screen. The user can move the cursor across the screen, letter to letter, spelling out words, sentences, and sequences. The Eyegaze System is also equipped with voice synthesis technology, which speaks the text the user has selected.
