From birth, children like to track moving colorful objects with their eyes. In our infant lab we use eye tracking to measure the development of object representation and the ability to understand social interactions in normal children and children with Autism. 

We have spent a lot of time setting up different eye trackers to work with babies in our lab. Tobii remote eye trackers provide several advantages compared to other systems. First, they offer large freedom of head movement and non-intrusiveness, which is required for baby testing. Calibration and recording is also much more straight-forward than anything else we have seen. It is easy to set up attention-grabbing stimuli using video and audio, calibration routines are quick and easy and specifically designed for babies, and eye tracking is fully automatic.
 
We have collected large volumes of very high quality data using our Tobii systems. This has enabled us to obtain research results in infant studies that would have been extremely time-consuming or even impossible using traditional eye tracking systems.

Recently we upgraded our old Tobii 1750 eye tracking systems to new Tobii T60 Eye Trackers. The new hardware allows for twice as much head movement and the eye tracking data is even more accurate. It also provides automatic bright and dark pupil optimization.
