Eye tracking
Eye tracking is the process of measuring either the point of gaze ("where we are looking") or the motion of an eye relative to the head.( www.eyetracking.com)
Eye tracking is great for showing the hotspots on a page (to find out where users look at the most) and the dead zones (where users don't look at all).
Eye tracking is most useful when you want to test:

* Brand awareness - To assess how much people notice the branding in terms of logos, brand values and brand titles.
* Navigation - To identify any conflicting terms as well as how different navigation layouts interact with each other.
* Page layout - To show how a page layout and colour scheme affect the way users scan a page.
