What is Eye-Tracking?

Eye tracking is a non-invasive video technique that uses infrared light to record eye movements. This method gives us insights into perceptual processing and helps us to explore and better understand the development of cognitive, linguistic and socio-emotional skills from infancy to adulthood.


What happens during the testing?

In our lab we use two types of eye tracking. With screen-based eye tracking, the child sits about 60 cm away from a screen. An eye-tracker is attached to records where on the screen the child is looking. The child should move as little as possible.


With the help of so-called eye-tracking glasses, we can also examine the eye movements of babies and small children in a real setting (e.g. in a play situation with a parent). The child is given a headband with two mini-cameras, one of which films the child's eye and the other the environment from the child's point of view.


Both types of eye tracking are harmless and don't hurt.
