Collaborative Gaze Footprints: Correlates of Interaction Quality
Dual eye tracking offers new possibilities for the analysis and diagnosis of collaborative interaction. Cross-recurrence analyses and visualizations offer insight into how closely two collaborators’ gaze follow each other. We contrast two cases to illustrate how gaze cross-recurrence can be used as a correlate of high and low quality interaction. The intriguing graphical patterns that result from the time coupled traces of the collaborators’ fixations are footprints of the quality of the interaction. Good quality interaction features a higher recurrence rate than low quality interaction. The graphical structure of the recurrence plots indicates whether collaborators divide labor and whether they are sharing visual attention.
