Eye Tracking Framework for Analyzing Cognitive Bias

Michael Raschke and Thomas Ertl, University of Stuttgart, Germany

Analyzing cognitive bias with eye tracking? Yes, of course! In our presentation we will present a method for analyzing cognitive bias using eye tracking with three steps: 1) annotating graphical elements or regions in a visualization with semantic information; 2) defining an idealized scan path for a given visual task; 3) analyzing eye movement patterns and comparing scan paths from a user experiment with idealized scan path for identifying areas on the stimulus which lead to a cognitive bias.
