In response to the high demand for digital learning as a surrogate physical experiences, virtual reality (VR) is positioning itself tool creating educational experiences. VR technology faces number of ethical issues, including reduction users' autonomy, health problems, and privacy concerns. The use realism in education can turn out be double-edged sword. While realistic visualizations promote some content domains, they hinder comprehension others. Furthermore, effects on also depend learners' spatial abilities. Letting young children teenagers engage experiences expose them manipulation, could lead may infringe their privacy. short, severely limit autonomy ways.

Eye-tracking plays a crucial role in the development of virtual reality devices, neuroscience research, and psychology. Despite its significance numerous applications, achieving an accurate, robust, fast eye-tracking solution remains considerable challenge for current state-of-the-art methods. While existing reflection-based techniques (e.g., "glint tracking") are considered to be very their performance is limited by reliance on sparse 3D surface data acquired solely from cornea surface.

Eye tracking has shown great promise in many scientific fields and daily applications, ranging from the early detection of mental health disorders to foveated rendering virtual reality (VR). These applications all call for a robust system high-frequency near-eye movement sensing analysis high precision, which cannot be guaranteed by existing eye solutions with CCD/CMOS cameras. To bridge gap, this paper, we propose Swift-Eye, an offline precise pupil estimation framework support analysis, especially when region is partially occluded. Swift-Eye built upon emerging event cameras capture high-speed eyes temporal resolution. Then, series bespoke components are designed generate high-quality video at frame rate over kilohertz deal occlusion caused involuntary blinks. According our extensive evaluations on EV-Eye, large-scale public dataset using cameras, shows robustness against significant occlusion. It can improve IoU F1-score 20% 12.5% respectively, compared second-best competing approach, 80% occluded eyelid. Lastly, it provides continuous smooth traces pupils extremely resolution number potential such as diagnosis, behaviour-brain association, etc. The implementation details source codes found https://github.com/ztysdu/Swift-Eye.
