Eye Tracking: A Rich Source of Information for User Modeling

This presentation focuses on two aspects of eye-tracking research: using point-of-gaze information to look at shifts in attention and using changes in pupil diameter to know when cognitive demands occur. Both aspects are immediately important in cognitive modeling because as modelers, we want to understand as much as we can about individuals’ underlying cognitive processes. Eye tracking yields very precise behavioral and physiological data that contribute to our understanding.
