Eye-Gaze

Abstract

This chapter considers the principles of eye movements and how eye-gaze recording and analysis techniques can be used to study and understand the consequences of design decisions. First we look at the different ways in which gaze naturally reacts to different RSVP-like presentations and describe four distinct gaze behaviours sufficient to characterise the significant aspects of eye movements observed during RSVP sequences: (1) visual search, (2) steady gaze, (3) nystagmus, and (4) visual pursuit. The chapter concludes with a discussion of ways of representing and presenting eye-gaze information to best effect.
