http://www.ojr.org/ojr/stories/070312ruel/Now, the crotch fixations (if that's what they are, there's at least one alternative explanation that needs to be zonked) are interesting. But the rest of the article is interesting.
First, one image (with fairly consistent red blobs across the top of a webpage) shows that people scan a page with the same distance between fixations. I knew that people hopped around; it's nice that they do it in essentially the same way.
Second, the business about photos is also fascinating: people apparently take a short fixation to ID a photo and then move to something more 'interesting' than models or ads.
It's meaningful for editors and writers, for people in graphic design, for textbook writers, and also for webpage designers. I knew one psycholinguist a few years ago (she's now at NC-Chapel Hill). She was big into eyetracking methologies for getting at real-time processing of language--it's a really neat way of figuring out what people's brains are doing without their knowing it. Anyway, her husband worked for a large software corporation testing and refining their webpages and software screen layout. Things were known about how people looked at pages since the '90s, but I'm fairly sure at that time he wasn't into using eyetracking. At some point in the recent past he probably turned to his wife and said, "Ok, this eyetracking stuff ... let me in." Eh, only $50k or so for the full set-up.
on edit: why look at crotches? Well, if you're male you certainly want to know a person's sex ... ok, pretty much everybody's. For a few reasons. First, sex. If you're straight, you look at crotches: Got package? If yes, move on; if no, check out sexual object a bit more. The second reason is that men tend to compete with men: You scan a person, examine crotch ... he's male, and a competitor, both sexual and other. (The other option--much less likely, I think--is that guys check out the other person a bit more thoroughly; women look at faces and upper chest to see what they want, men want more info: by looking at face/upper chest and crotch they can form a pretty good mental representation of everything from mid-thigh up, and what's happening from the knees down is pretty useful information. To disambiguate you'd need to have images so large that two fixations, one face-level and the other crotch-level, wouldn't let the observer have the entire or nearly entire torso in focus.)
