Eye tracking is an unobtrusive way to collect eye movement data from infants and children. The Baby Lab at UCD have a Tobii X120 eye tracker, which basically consists of a little black box that sits on a computer. At the beginning of the experiment, your infant will be shown a series of dots on the screen. This is done to calibrate eye movement and make sure that the eye tracking is picking up your child’s eye movements. Your infant will then be shown a series of stimuli on the screen and the eye tracker will track their eye gaze patterns. Nothing will be attached to your child and this equipment is extremely safe.
