Introduction to Eye and Gaze Trackers

• In the previous chapters of the book, you will have seen multiple applications for using (and the benefits of using) a gaze tracker. In this chapter, you will be given more insight into how an eye tracker operates. Not only can this aid in understanding the eye tracker better, it also gives important information about how future applications might improve on current ones, by using more of the information available from the eye tracker: as we shall see, an eye tracker can often provide you with more information than just coordinates on a screen. This chapter gives an overview of the components of an eye tracker and introduces basics of gaze modelling. It helps in understanding the following chapters which each provide some details of how to build an eye tracker. This section has technical content, but it is our hope that also readers not particularly interested in the details of eye and gaze trackers will gain some useful insights.
