This document shows a highly portable eye tracker that can be built using two DejaView CamWear systems, a pair of safety glasses, zip ties and some flexible low-gauge wire. Video is recored to SD cards and processed offline using the visible spectrum starburst algorithm. Ease of Construction = High.

This tutorial provides a step by step description of a low-cost approach to building an infrared video based eye tracker from consumer-grade web cameras. This system is capable of real-time eye tracking. Ease of Construction = Low.
