Abstract

This article presents a simple and intuitive way to represent the eye-tracking data gathered during immersive virtual reality exposure therapy sessions. Eye-tracking technology is used to observe gaze movements during virtual reality sessions and the gaze-map chromatic gradient coding allows to collect and use these important information on the subject’s gaze avoidance behavior. We present the technological solution and its relevance for therapeutic needs, as well as the experiments performed to demonstrate its usability in a medical context. Results show that the gaze-map technique is fully compatible with different VR exposure systems and provides clinically meaningful data.
