Eye tracking can provide useful metrics for usability testing and comparing design concepts, but certain conditions need to be considered: 1) Eye tracking is best for tasks without think-aloud to avoid biasing where participants look. 2) Metrics like fixations and gaze duration indicate attention levels, but not necessarily interest versus confusion. 3) Areas of interest allow comparing attention between design variants by metrics like early fixations. 4) Ensure proper participant screening and calibration to minimize lost eye tracking signals.
