Instead of eyeball tracking for usability professionals, here’s a way to track the mouse movements and click events of a user on a page.

The “movelogger” records the mouse movement a users does on a web site. Just before the user leaves the current page, the recorded data get posted back to the server using AJAX.
The cool thing is that you can “replay” these movements afterwards.
