Who's using the Eyegaze System?
Eyegaze Systems are in use around the world. Its users are adults and children with cerebral palsy, spinal cord injuries, brain injuries, ALS, multiple sclerosis, brainstem strokes, muscular dystrophy, and Werdnig‑Hoffman syndrome. Eyegaze Systems are being used in homes, offices, schools, hospitals, and long‑term care facilities.
How does the Eyegaze System work?
As a user sits in front of the Eyegaze monitor, a specialized video camera mounted below the monitor observes one of the user's eyes. Sophisticated image‑ processing software in the Eyegaze System's computer continually analyzes the video image of the eye and determines where the user is looking on the screen. Nothing is attached to the user's head or body.
How does the user run the Eyegaze System?
A user operates the Eyegaze System by looking at rectangular keys that are displayed on the control screen. To "press" an Eyegaze key, the user looks at the key for a specified period of time. The gaze duration required to visually activate a key, typically a fraction of a second, is adjustable. An array of menu keys and exit keys allow the user to navigate around the Eyegaze programs independently.
What skills does the user need?
- Good control of one eye
- Ability to keep his head still in front of the camera
- Some reading or word recognition skill
How do you calibrate?
A 15-second calibration procedure is required to set up the System for a particular user. To calibrate, the user fixes his gaze on a sequence of small circles that the system displays on the Eyegaze screen. There is no need to recalibrate if the user moves away from the Eyegaze System and returns later.
