This page provides some basic information about what eye-tracking is and how it works. How does it work? Eye-trackers use a special camera to record a person’s eye movements and where they are looking while viewing images or videos being displayed on a computer screen. Infrared light (which is invisible to humans) is reflected from the eye and sensed by a video camera located below the computer screen. Information can then be gathered about the gaze position and eye movements at any time point throughout the viewing. Our eye-tracker is specially designed for babies and children. It is extra sensitive and does not require the head to be kept still as with some adult eye-trackers. Why is it useful? Eye-tracking is a really useful and noninvasive way of finding out what babies and children are interested in looking at. It can tell us how long they can pay attention to something for, how well they can remember things and how good they are at controlling their eye movements. This can inform us about their developing social skills and things like attention and memory. This could be useful for identifying infants who are having difficulties with these skills at an early age. This article was published on 2024-09-10
