Discount Eye Tracking: The Enhanced Restricted Focus Viewer
Peter Tarasewich, Stephanie Fillion · Journal of the Association for Information Systems · 2004
This paper discusses the design and implementation of a unique software tool, the enhanced restricted focus viewer (ERFV), for tracking the visual attention of users in hyperlinked environments such as web sites.The software collects data such as mouse clicks along with the path of the user's visual attention as they browse a site.Unlike traditional eye-tracking procedures, the ERFV requires no hardware other than a personal computer.In addition to cost and time savings, the ERFV also allows the administration of usability testing to groups of subjects simultaneously.The benefits of the ERFV are demonstrated through an experiment that evaluated the usability of two web sites that were equivalent in content but differed in terms of design.
