EyeWriter System Requirements
The goal of the hardware component of the EyeWriter project is to make the most simple and inexpensive eye-tracking head-set possible to use with the "EyeWriter" software suite.
Obviously, there are numerous ways to make eye-tracking hardware. Many of these designs, especially those produced for academic research projects (Open Eyes ), have already been published openly on the internet. There are also commercial products available -- costing in the range of ~$20,000 US or more-- that are specifically designed to enable quadriplegics to communicate using their eyes.
This project is an attempt to address a gap in the development of low-end eye tracking systems, ie to make a super-cheap, eye-tracker that could be made by almost anyone, almost anywhere. This instruction set details how to make your own solderless eyetracker for only $50 dollars using a hacked PS3 Eye and a cheap pair of sunglasses
