Write With Your Eyes

Dasher with an eye-tracker

AVI of Dasher with an eye-tracker: eye.avi (54MB)


We have an eyetracker from EyeTech Digital Systems. It consists of two infra-red emitters, and a camera which plugs into the back of a PC.


The eyetracker works under MS Windows and replaces the mouse pointer with a users gaze. Below is a photo of me using Dasher to write with my eye movement. I can write at about 50-100 characters per minute (10 - 20 wpm). With further development, faster speeds should be possible.
