The effect of cumulative eye movements' guidance of experts on transition from novice to expert

Based on the assumptions of cognitive load theory, this study aims to utilize the eye movement data collected from multiple experts to scaffold novice graphic designers. The study has two main stages. In the first stage, eye tracking was used to record the eye movements of 7 experts, who covered eight topics explaining how to use Photoshop. The areas of interest and fixation durations were analyzed for each topic to extract the common patterns. Instructional videos were produced with the guidance of both eye movement patterns and multimedia design principles. In the second stage of this study, those videos were delivered to 30 university students. The experiment group watched the guided videos, whereas the control group watched straight videos, i.e., content without guidance. The guidance elements were reduced (faded) as students got familiar with the interface. All participants were assigned to perform tasks as soon as they completed the videos. The findings showed that the knowledge scores did not significantly differ between groups. Still, the average performance scores of the experiment group were considerably higher than that of the control group. Considering the transition process, the experiment group outperformed the others. The topics in which experts' eye movements highly matched each other resulted in high-performance gaps among groups.
