Happy to have defended my doctoral thesis at Aalto University on Friday!

Many thanks to my opponent Prof. Adam Sanborn, my supervisor Prof. Antti Oulasvirta, and of course all my collaborators.

7/8 The paper also presents analysis of search times; we find that GUI type (mobile, desktop or webpage), absence/presence of the target and whether the target is presented in a textual or image format affect search times more than visual complexity.
Figure with three panes with search time on the y-axis and different independent variables on the x-axis. First pane depicts the impact of GUI type and presence/absence of the target: search is fastest with target present and mobile UIs. The second pane shows the impact of cue type and presence/absence of the target: search is fastest with target present and image cues. The final pane shows the impact of visual clutter factor score: again, search is slower when the target is absent and when visual clutter increases.

3/8 We synthesize our results in a three-stage pattern of search: Guess, Scan and Confirm.
A figure with three heatmaps showing allocation of fixations on a GUI. The first heatmap depicts a Guess stage where fixations are directed to upper-left, the second a Scan stage where the fixations spread out and the third a Confirmation stage where fixations are concentrated at the target location, which is the lower-left quadrant.
