What is Eyetracking? • Definitions • Saccade: A quick movement of the eye in order to move focus from one area to the next. • Fixation: The time spent looking at the newly found area. • AOI: Area of Interest • Eyetracking: A technique used to determine the eye movement and eye-fixation patterns of a user.
What is Eyetracking? • Saccade and fixation • Not random • What is important • Eyetracking vs. other testing methods
Why is it Important? • “The Added Value of Eyetracking in the Usability Evaluation of a Network Management tool” • Task 1: The participants were required to start the system and to determine whether new delay metrics have been collected.
How do Designers Obtain this Information? • Multiple ways to track where a user looks • Sensors attached to the user’s face • Head-mounted video systems • Restrictive video-based system • Non-contact, non-restrictive video-based system
How Do Designers Obtain this Information? • “The eyetracking equipment we use for our research...Looks like a normal computer… that's exactly the point, because we want users to work normally.”
How do Designers Obtain this Information? • Compiling information • Heat maps
How Do Designers Use this Information? • Variety of fields • Software design • Web design • Advertising
