Eye tracking research can sometimes feel like a bit of a terminological minefield, particularly if you are new to the topic. In this blog (the first of a series) I outline some of the key terms that refer to eye movements themselves. Future blogs will address the terminology around eye tracking data
It is not uncommon to see an adult hold up a finger and move it across a baby's field of view to see if the baby can fixate and follow the finger's movement with his eyes. There is great interest in babies meeting milestones in order to assess health and, if necessary, provide support. Can, in fact,
The concept of visual angle is critical to many aspects of eye tracking research, but it is one of those things that people are somehow just expected to understand. This blog is my attempt to explain visual angle in the way I wish someone had explained it to me, e.g. with the bare minimum of math...
Researchers are increasingly using eye trackers to explore changes in pupil size (pupillometry) in order to reveal insights into cognitive processes. EyeLink eye trackers are capable of detecting changes in pupil size of just 0.1% of the pupil diameter, and their high sampling rates allow pupilliary
The benefits of combinging Eye Tracking with EEG Recording Researchers are increasingly aware of the benefits of combining eye tracking with EEG and other neurophysiological recording equipment. One of the most common rationales for recording simultaneous EEG and eye tracking data is "artefact
What is eye tracking? Put simply, eye tracking is the process of measuring eye movements. A typical goal for eye tracking research is to establish where people look (i.e., their “point of regard” or “gaze"). To this end, scientists usually use a video-based eye tracker, such as the EyeLink 1000
