Abstract

The main objective of gaze trackers is to provide an accurate estimate of the user’s gaze by using the eye tracking information. Gaze, in its most general form, can be considered to be the line of sight or line of gaze, as 3D (imaginary) lines with respect to the camera, or as the point of regard (also termed the point of gaze). This chapter introduces different gaze estimation techniques, including geometry-based methods and interpolation methods. Issues related to both remote and head mounted trackers are discussed. Different fixation estimation methods are also briefly introduced. It is assumed that the reader is familiar with basic 3D geometry concepts as well as advanced mathematics, such as matrix manipulation and vector calculus.
