Researchers with DIEM are working on a project "focused on understanding human vision during complex real-world scene perception"--which from what I can tell means they, like that wasted guy at the bar, want to know what the fuck you're looking at, asshole. As part of that research, they did a little experiment with Paul Thomas Anderson's There Will Be Blood:
11 adult viewers were shown [a clip from the film] and their eye movements recorded using an Eyelink 1000 (SR Research) infra-red camera-based eyetracker. Each dot represents the center of one viewer's gaze. The size of each dot represents the length of time they have held fixation.
And now you, too, can play scientist with this video of their research. The expanding, Atari-style bomb circles mean you caught someone staring.
All male subjects in the study followed up the experiment by noting that they'd totally have been looking at a hot babe had there been one on-screen; they were just looking at dude-faces because that's all there was, man.
