Building a lightweight eyetracking headgear
Abstract
Eyetracking systems that use video-based cameras to monitor the
eye and scene can be made significantly smaller thanks to tiny
micro-lens video cameras. Pupil detection algorithms are
generally implemented in hardware, allowing for real-time
eyetracking. However, it is likely that real-time eyetracking will
soon be fully accomplished in software alone. This paper
encourages an “open-source” approach to eyetracking by
providing practical tips on building a lightweight eyetracker from
commercially available micro-lens cameras and other parts. While
the headgear described here can be used with any dark-pupil
eyetracking controller, it also opens the door to open-source
software solutions that could be developed by the eyetracking and
image-processing communities. Such systems could be optimized
without concern for real-time performance because the systems
could be run offline.
