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 … Read more about Eye Tracking for Pupillometry
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 rejection." Blinks and eye movements themselves (even tiny … Read more about Eye Tracking and EEG
Only a generation ago, eye tracking typically required complex and expensive equipment and considerable technical expertise on the part of the researcher. Analyzing eye movement data was often a slow and laborious process. As such, it is perhaps unsurprising that it was a relative niche field. … Read more about How does eye tracking work?
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 Plus. … Read more about What is eye tracking?
