Eyetracking
Eyetracking is a method of testing the effectiveness and usability of a Web site. In an eye tracking study, multiple users are instructed to perform a certain action within a site (usually unfamiliar to them). Special equipment makes it possible to measure exactly which parts of a page they view and for how long.
Viewing behavior can provide a lot of information about website clarity and how visitors search for information on a site. The results of this research can be used to improve a Web site or test whether a new design meets the stated requirements for usability.
Eyetracking is also used for other purposes, such as testing the readability of a text or the effectiveness of an advertisement. Do the audience's eyes go first to the advertiser's photo, logo or slogan? And how long are the different parts viewed?
