Eye tracking is used to study the differences in social interaction and visual precursors to attention in social contexts between typically developing children and children with autism spectrum disorder.

Tobii Pro eye trackers are known for their exceptional tolerance of substantial, dynamic head movement which allows for minimal restrictions on the subjects' natural actions. This makes them ideal for infant and child studies, as well as atypical populations.
