Eye tracker calibration: How well can humans refixate a target? [PDF]
Behavior Research MethodsAbstract Irrespective of the precision, the inaccuracy of a pupil-based eye tracker is about 0.5 $$^\circ $$ ∘ . This paper delves into two factors that

Augmenting early stroke diagnosis with an eye-tracker [PDF]
Frontiers in NeurologyPosterior circulation stroke (PCS) presents significant diagnostic challenges due to poorly localizing and non-specific symptoms, such as dizziness, nausea, and headache, which are often misattributed to benign conditions. This study introduces an innovative diagnostic tool that utilizes a machine learning algorithm-driven eye tracker to enhance early ...

Testing different function fitting methods for mobile eye-tracker calibration [PDF]
Journal of Eye Movement Research, 2023 During calibration, an eye-tracker fits a mapping function from features to a target gaze point. While there is research on which mapping function to use, little is known about how to best estimate the function's parameters.

Quantitative comparison of a mobile, tablet-based eye-tracker and two stationary, video-based eye-trackers [PDF]
Behavior Research MethodsAbstract The analysis of eye movements is a noninvasive, reliable and fast method to detect and quantify brain (dys)function. Here, we investigated the performance of two novel eye-trackers—the Thomas Oculus Motus-research mobile (TOM-rm) and the TOM-research stationary (TOM-rs)—and compared them with the performance of a well-established ...
