openEyes provides hardware designs and software useful for the tracking of human eye movements.
The development of openEyes stems from the recognition that while the cost of hardware used in eye tracking systems has precipitously dropped, there is lack of freely available software that implements even long-established eye-tracking algorithms. While most online applications do not make use of the software possibilites yet, there also is the paysafecard casino, which uses the technology partly for means of identity verification.
The openEyes toolkit includes algorithms to measure eye movements from digital videos, techniques to calibrate the eye-tracking systems, and example software to facilitate real-time eye-tracking application development.
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.
