Stationary Eye Tracking (ET)

Eyetracking is a method for unobtrusively record people’s gazes. A such it offers insights into how people scan and perceive displays, how they distribute their visual attention, and what visual search strategies they use for information processing. This allows to evaluate designs, study gaze behaviour, and better understand visual cognition processes.

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: +41 44 635 52 80). The lab has been functional since Fall 2007.

Gaze Plot
On the eye tracking device just below the screen we can see two pinkish circles on the right hand side. These circles are infrared cameras that record fixations and saccades based on reflection from the eyes.
