Superb analysis and study on how our eyes scan and sample images.

Excerpts:

In other experiments with static scenes, my colleagues and I have shown that even if the overall scene is hidden 150milliseconds into every fixation, we are still able to move our eyes around and find a desired object. Our visual system is built to deal with such disruptions and perceive a coherent world from fragments of information encoded during each fixation.

The second most striking observation you may have about the video is how coordinated the gaze of multiple viewers is. Most of the time, all viewers are looking in a similar place. This is a phenomenon I have termed Attentional Synchrony. If several viewers examine a static scene like the Repin painting discussed in David's last post, they will look in similar places, but not at the same time. Yet as soon as the image moves, we get a high degree of attentional synchrony. Something about the dynamics of a moving scene leads to all viewers looking at the same place, at the same time.

The main factors influencing gaze can be divided into bottom-up involuntary control by the visual scene and top-down voluntary control by the viewer's intentions, desires, and prior experience

We found that moments of attentional synchrony can be predicted by points of motion within an otherwise static scene (i.e. motion contrast).

Viewers' gazes are attracted by the sudden appearance of objects, moving hands, heads, and bodies. The greater the motion contrast between the point of motion and the static background, the more likely viewers will look at it. If there is only one point of motion at a particular moment, then all viewers will look at the motion, creating attentional synchrony.


At any one moment in the scene there is a principal action signified either by dialogue or motion. By minimising background distractions and staging the scene in a clear sequential manner using basic principles of visual attention, P. T. Anderson has created a scene which commands viewer attention as precisely as a rapidly edited sequence of close-up shots.

The benefit of using a single long shot is the illusion of volition. Viewers think they are free to look where they want but, due to the subtle influence of the director and actors, where they want to look is also where the director wants them to look. A single static long shot also creates a sense of space, clear relationship between the characters, and a calm, slow pace which is critical for the rest of the film. The same scene edited into close-ups would have left the viewer with a completely different interpretation of the scene.
