“…Visual behaviors have been studied in cognitive neuroscience, computer science, consumer science, environmental design, and psychophysiology (Epelboim and Suppes, 2001;Andrá et al, 2015;Muldner and Burleston, 2015). Although eyetracking is not a direct measure of visual acuity, it has been used as a useful tool in research and applications, such as usability research (Manhartsberger and Zellhofer, 2005), human factors research, and safety applications (Han et al, 2020), psychological/cognitive research (Mele and Federici, 2012), education and training (Tien et al, 2014), kinesiology and sports sciences (Lim et al, 2018), and car/airplane simulations (Palinko et al, 2010). However, a generally agreed limitation with eyetracking data is that while these data can explain overt attention, i.e., what is observed and perceived, they do not contribute to understanding the covert, such as why and how.…”
