Basics of Camera-Based Gaze Tracking
Dan Witzner Hansen, Päivi Majaranta · IGI Global eBooks · 2012
Most of the studies presented in this book use camera-based gaze trackers, used to monitor where the user is looking on screen or in the 3D environment. While a gaze tracker may resemble a blackbox device that miraculously determines the point of gaze, it actually consists of several hardware and software components with specific purposes. This chapter gives a brief introduction to the typical setup, composition and operating principles of eye and gaze tracking and it provides a simplified overview of camera-based gaze trackers that will be of use to all readers of this book.
