Time-Dependent Changes In Viewing
Behavior On Similarly Structured Web Pages

This article focuses on the impact of observation time and web page structure on viewing behavior. 63 subjects observed similarly structured pages of a popular commercial internet shop. Eye movements were recorded and analyzed regarding several saccade parameters, the individual fixation distribution by means of a progressive entropy approach, and the within- as well as between-subject congruency of fixation distributions. Our results show that viewing behavior significantly changed while subjects observed individual web pages.
In contrast, we only found little evidence for a change in eye movements across web pages and hence for an attention-related schema building. In this context, we also provide an
example of the impact of web page elements’ position on fixation probability.
