Mobile Eye Tracking

The GIVA research group uses an eye-tracking methodology to investigate research questions at the interface between human perception, cognition, and geovisualizations.

The portable eye-tracking glasses from SMI systems and Pupil Labs allow researchers to record eye movements anywhere, whether it's in the field or in the lab. The glasses feature an HD recording camera, they are lightweight, comfortable to wear, invisible and highly portable. Once the glasses are put on they are quickly calibrated to the participant so that you can see exactly where their eyes are attracted to.
