Abstract

We investigated the validity of two low-cost alternatives to state-of-the-art eye tracking technology: 1) prompting users to report from memory on their own eye movements, and 2) asking experienced web designers to predict the eye movements of a typical user. Users could reliably remember 70 % of the web elements they had actually seen. Web designers could only predict 46 % of the elements typically seen. Users were not particularly good at remembering the order of their fixations. We discuss how to further improve the validity of self-reported gaze patterns and suggest new areas that it may be used in.
