Abstract:

Eye tracking tools have recently attracted attention from usability professionals. Eye tracking offers usability researchers a new way to identify very fine-grained behaviors that indicate usability problems. This paper is a comparison of different types of eye tracking tools and their potential usefulness in usability testing. Specifically, the paper examines the cost of the systems, system types, sampling rate, and some system limitations. The paper aims to provide a basic introduction to technical communicators who are considering adding an eye- tracking system to their toolkit.
