Introduction to Gaze Interaction
Päivi Majaranta, Mick Donegan · IGI Global eBooks · 2012
Gaze interaction, as understood in this book, provides a means to exploit information from eye gaze behaviour during human-technology interaction. Gaze can either be used as an explicit control method that enables the user to point at and select items, or information from the user’s natural gaze behaviour can be exploited subtly in the background as an additional input channel without interfering with normal viewing. This chapter provides a brief introduction to the potential for applied gaze tracking, with special emphasis on its application in assistive technology. It introduces common terms and offers a concise summary of previous research and applications of eye tracking.
