Eye-tracking for Online User Experience | Jainlab
PIs: Eakta Jain


Cognitive scientists and psychologists have long noted the "picture superiority effect", that is, pictorial content is more likely to be remembered and more likely to lead to an increased understandingof the material. We investigated the relative importance of pictorial regions versus textual regions on a website where pictures and text co-occur in a very structured manner: video content sharing websites. In our study, we tracked participants' eye movements as they performed a casual browsing task, that is, selecting a video to watch. The fixations were coded as falling on one of two areas of interest: thumbnail image or title text region. We found that participants allocated almost twice as much attention to thumbnails as to title text regions. They also tended to look at the thumbnail images before the title text, as predicted by the picture superiority effect. These results have implications for both user experience designers as well as video content creators.
