Abstract

While fixation data and saccadic indices have been employed as individual measures, less frequent analysis has been attempted on the sequence or pattern data that these two indices together create. The patterns of fixations and saccades are rich and complex, and hence, they are typically studied as individual paths or parts of paths that are isolated. Analysis is usually a visual comparison, although more recently there have been studies that have compared scan patterns statistically [Josephson and Holmes 2002; Pan et al. 2002; Yarbus 1967]. In the current work we explore a method for deriving an "average" scan pattern aggregated from many users viewing the same visual stimulus (web site).
