Abstract In eye tracking research, finding movement patterns and similar strategies between participants’ movements is important to understand task solving obstacles. this application paper, we present a graph comparison method using radial graphs that show Areas of Interest (AOIs) their transitions. An analyst investigates single based on dwell times, directed transitions, temporal AOI sequences. Two can be compared directly changes may analyzed. A list matrix approach facilitate the contrast more than two guided by visually encoded similarities. We evaluated our in case studies with three visualization experts. They identified transition across participants, groups outliers.
