Figure 5: Webcam eye-tracking methodology – eye metrics.
(a) An overlay of all participants’ fixations of the range 0.5-5 seconds of image viewing are shown as a fixation-based heatmap for both timepoints, respectively. (b-d) The results for t1 are shown in blue, and t2 are shown in green. The P-value shows the result of the statistical testing. Each circle represents one participant. The median and 25th-75th percentile are shown for the violin plots. (b) Violin plots illustrate the fixation count on the dAOI and the vAOI for both timepoints, respectively. (c) Violin plots illustrate the fixation duration on dAOI and vAOI for both timepoints, respectively. (e) Violin plots illustrate the time to first fixation on dAOIs and vAOIs fixation. Abbreviations: *=View time adjusted values were used; dAOI=diagnostically most relevant areas of interest; vAOI=visually most salient but diagnostically irrelevant areas of interest; t1=timepoint 1 after 10 course sessions; t2=timepoint 2 after 20 course sessions.
