Suggested Empirical Guidelines

Abstract

This chapter attempts to provide guidelines for conducting an eye tracking experi-ment, e.g., performing a usability study incorporating eye movements. It is not pos-sible to provide a cookbook recipe for doing so, however. The experiment must be designed within the context of the phenomenon under investigation. Nevertheless, a general outline can be provided to help guide the process of experimental design. Here, the discussion is biased somewhat towards performance measurement, a spe-cific form of testing method often seen in human factors research, particularly as practiced within computer science, and more specifically still within the human– computer interaction community. Other testing methods not addressed here include ethnographic studies, co-discovery, or think-aloud.
