This research paper, published by Marcel Claus, Frouke Hermens, and Stefano Bromuri, discusses a user study of visualisations of spatio-temporal eye tracking data. The study compares four different visualization techniques – chord diagram, scanpath, scarfplot, space-time cube – based on two types of data-sets (eye movements towards adverts, eye movements towards pairs of gambles). The accuracy of the answers depended on the data-set, the question that needed to be answered, and the type of visualization. The study concludes that there is no single best visualization of the spatio-temporal aspects of eye movements and that a user study may be beneficial to determine the optimal visualization of the data-set and research question at hand.
