The video below shows the human learning laboratory here at the University of the Basque country. It is equipped with four experiment stations, and an eye-tracking station. Each station has a Dell Optiplex computer running an ATI 2400hd video card and a 22in monitor.
The eye tracker is a RED 250 system from SMI Vision.
There is an additional Optiplex system for general lab use (e.g., Office programs, internet).
