Preregistration: Using a test battery to compare three remote, video-based eye-trackers (comparET)

Eye-tracking research is based on data collected with a multitude of eye-tracking devices. The comparability of results obtained by different devices is unclear. This study aims to investigate the comparability of data of three remote eye-tracking devices, the Gazepoint GP3HD Desktop, the Tobii Pro X3-120, and the EyeLink 1000+, using an extensive test battery. Data of N = 25 participants will be collected, who will be recruited by subject pool advertisement, email lists, and personal invitation. Inclusion criteria comprise a successful calibration with all three eye-tracking devices. Participants will receive monetary compensation. Participants will complete eight eye-movement tasks, consecutively measured by each eye-tracker. The tasks measure various eye-tracking parameters, such as accuracy, precision, smooth pursuit, microsaccades, or pupil dilation. The measure of data quality obtained in each task, will be compared between devices. This is a preregistration of the article: Spitzer, L., & Mueller, S. (2022).
