Abstract In this paper, we present a review of how the various aspects any study using an eye tracker (such as instrument, methodology, environment, participant, etc.) affect quality recorded eye-tracking data and obtained eye-movement gaze measures. We take to represent empirical foundation for reporting guidelines involving tracker. compare five existing database 207 published studies. find that vary substantially do not match with actual practices. end by deriving minimal, flexible guideline based on research (Section “An empirically minimal guideline”).

Eye tracking is becoming increasingly available in head-mounted virtual reality displays with various headsets integrated eye trackers already commercially available. The applications of are highly diversified and span multiple disciplines. As a result, the number peer-reviewed publications that study has surged recent years. We performed broad review to comprehensively search academic literature databases aim assessing extent published research dealing reality, highlighting challenges, limitations areas for future research.

The cameras in modern gaze-tracking systems suffer from fundamental bandwidth and power limitations, constraining data acquisition speed to 300 Hz realistically. This obstructs the use of mobile eye trackers perform, e.g., low latency predictive rendering, or study quick subtle motions like microsaccades using head-mounted devices wild. Here, we propose a hybrid frame-event-based near-eye gaze tracking system offering update rates beyond 10,000 with an accuracy that matches high-end desktop-mounted commercial when evaluated same conditions. Our system, previewed Figure 1, builds on emerging event simultaneously acquire regularly sampled frames adaptively events. We develop online 2D pupil fitting method updates parametric model every one few Moreover, polynomial regressor for estimating point real time. Using first event-based dataset, demonstrate our achieves accuracies 0.45°-1.75° fields view 45° 98°. With this technology, hope enable new generation ultra-low-latency gaze-contingent rendering display techniques virtual augmented reality.

A growing number of virtual reality devices now include eye tracking technology, which can facilitate oculomotor and cognitive research in VR enable use cases like foveated rendering. These applications require different performance, often measured as spatial accuracy precision. While manufacturers report data quality estimates for their devices, these typically represent ideal performance may not reflect real-world quality. Additionally, it is unclear how precision change across sessions within the same participant or between influenced by vision correction. Here, we Vive Pro Eye built-in tracker a range 30 visual degrees horizontally vertically. Participants completed ten measurement over multiple days, allowing to evaluate calibration reliability. Accuracy were highest central gaze decreased with greater eccentricity both axes. Calibration was successful all participants, including those wearing contacts glasses, but glasses yielded significantly lower performance. We further found differences (but precision) two headsets, estimated participants' inter-pupillary distance. Our metrics suggest high reliability serve baseline expected experiments.

Abstract Over the past few decades, there have been significant developments in eye-tracking technology, particularly domain of mobile, head-mounted devices. Nevertheless, questions remain regarding accuracy these eye-trackers during static and dynamic tasks. In light this, we evaluated performance two widely used devices: Tobii Pro Glasses 2 3. A total 36 participants engaged tasks under three dynamicity conditions. “seated with a chinrest” trial, only eyes could be moved; without both head were free to move; walking walked along straight path. During seated trials, participants’ gaze was directed towards dots on wall by means audio instructions, whereas maintained their bullseye while it. Eye-tracker determined using computer vision techniques identify target within scene camera image. The findings showed that 3 outperformed terms trials. Moreover, results suggest employing chinrest case is counterproductive, as it necessitates larger eye eccentricities for fixation, thereby compromising compared not chinrest, which allows movement. Lastly, found who reported higher workload demonstrated poorer accuracy. current may useful design experiments involve eye-trackers.

Abstract This paper aims to compare a new webcam-based eye-tracking system, integrated into the Labvanced platform for online experiments, “gold standard” lab-based eye tracker (EyeLink 1000 - SR Research). Specifically, we simultaneously recorded data with both trackers in five different tasks, analyzing their real-time performance. These tasks were subset of standardized test battery trackers, including Large Grid task, Smooth Pursuit movements, viewing natural images, and two Head Movements (roll, yaw). The results show that system achieved an overall accuracy 1.4°, precision 1.1° (standard deviation (SD) across subjects), error about 0.5° larger than EyeLink system. Interestingly, (1.3°) (0.9°) slightly better centrally presented targets, region interest many psychophysical experiments. Remarkably, correlation raw gaze samples between was at 90% task 80% Free View Pursuit. Overall, these put performance roughly on par mobile devices (Ehinger et al. PeerJ , 7 e7086, 2019; Tonsen al., 2020) demonstrate substantial improvement compared existing webcam solutions (Papoutsaki 2017).
