Large Eye-tracking study

Staff in the lab are doing this in a collaboration between EMRA, COGAIN, the internationional committee for standardizing data quality measurements and many of the eye-tracking manufacturers.  There is a lot of unsubstantiated talk about how good or bad a specific eye-tracker is, whether it gives data that suits reading research, scene viewing or disability research, and this possibly skews boths publications and sales in a direction only based on subjective impressions. What the study set out to do is to examine the accuracy. precision and latency of each of the eye-trackers, and how these data quality measures depend on the characteristics of the participant: whether s/he wears glasses, mascara or whether is from Europe, Africa or Asia. By doing this, we hope to have an unprecendented overview of the quality of the leading eye-trackers in all kind of eye movement research that can serve as guidance for researchers, journal editors and reviewers, and manufacturers.
