I conducted eye-movement research on reading comprehension in my graduate work on my M.A. and Ph.D. in Cognitive Psychology back in the early 80’s. Eye-tracking hardware and software have come a long way since then and they provide very interesting analyses of user experiences with applications and websites.

This article summarizes some results of eye-tracking studies on the web. Nice summary, but I wish they had included references for each of their lessons.

Take a look at the article!
