Figure 3.

Heat maps illustrating the extent of eye movement search patterns overlaid on top of representative examples of low, medium, and high crowd density levels of visual distractors. The color scheme of the heat maps represents differing levels of gaze data density across spatial regions of the screen space (yellow indicates more time looking in an area, and blue indicates less time). There is consistent clustering of eye movements across the levels of distractor density, reflecting a tight flame shape around the target as they locate and pursue. Note further dispersion of gaze data from the target as crowd density increases.
