Abstract:

This paper's focus is on the challenges associated with collecting eye-tracking data. Despite operator training conducted by the manufacturer, one year of experience with eye-tracking and extensive calibration, the data collection success rate in the current investigation was very low; only six out of sixteen participants (37.5%) were successfully eye-tracked. We discuss possible explanations for this low success rate, and why we do not currently believe that eye-tracking is ready to be employed in usability laboratories.
