Abstract

The use of recorded eye movements, or scanpaths, has been demonstrated as an effective visualization for feed-forward visual search training, instruction, and stimulated retrospective think-aloud usability testing. In this paper we show that creation of a scripted or recorded video of an expert's think-aloud session augmented by an animation of their scanpaths can result in an effective aid for learners of visual search. Because the creation of such a video is relatively easy, the benefits-to-cost ratio may potentially be substantial, especially in settings where learned visual scanning strategies are indicators of expertise. We suggest that two such examples are examinations of Chest X-Rays and histological slides. Results are presented where straightforward construction of an instruction video provides measurable benefit to novice as well as experienced learners in the latter context.
