GIVA's Eye Movement Lab

Images below show the eye movement lab belonging to the GIVA (Geographic Information Visualization and Analysis) unit, located at the University of Zurich's Irchel campus, in the Geography department (room Y25-L9, tel: +41446355280). The lab has been functional since Fall 2007.

The technical setup of the lab consists of an eye tracking device and a workstation (both seen at the right) with the following specifications:

The two white dots in the black square area on the screen represent the two eyes and show the real-time tracking.

On the screen we can see a 'gaze plot' - this is a post-recording process where the fixations and saccades are overlain on the stimuli for initial visual interpretation.

In this image, just below the display, we see the tracker when its near infrared lights are active.

For your questions or comments regarding the lab, please contact Prof. Dr. Sara Fabrikant and/or Dr. Arzu Coltekin.
