Webpage eye tracking

This is somewhat interesting... both for webpage design and for its cognitive implications.

"In our new eyetracking study, we recorded how 232 users looked at thousands of Web pages. We found that users' main reading behavior was fairly consistent across many different sites and tasks. This dominant reading pattern looks somewhat like an F and has the following three components: Users first read in a horizontal movement, usually across the upper part of the content area. This initial element forms the F's top bar. Next, users move down the page a bit and then read across in a second horizontal movement that typically covers a shorter area than the previous movement. This additional element forms the F's lower bar. Finally, users scan the content's left side in a vertical movement. Sometimes this is a fairly slow and systematic scan that appears as a solid stripe on an eyetracking heatmap. Other times users move faster, creating a spottier heatmap. This last element forms the F's stem."

I wonder if this is because webpages are typically designed in this manner? I would like to see some scene statistics done on types of web pages in much the same way Aude Oliva and Torralba have done with scenes. It would be interesting to connect the two.
