下面摘抄文中的几个图：
人类的阅读视线变换：
The eyes most often fixated first in the upper left of the page, then hovered in that area before going left to right. Only after perusing the top portion of the page for some time did their eyes explore further down the page.
网页的价值分块：
Dominant headlines most often draw the eye first upon entering the page -- especially when they are in the upper left, and most often (but not always) when in the upper right.
注意：这只是，人们第一次去看某个页面的时候的视线图，如果某个人常去某个网页，他会形成自己的看法，会改变看这个网页的视线轨迹。那时候，上面的图可能就有点不太适用了。
