Front camera eye tracking for mobile VRFront camera eye tracking for mobile VR Σύντομη Δημοσίευση σε Συνέδριο Conference Short Paper 2022-05-062020enUser fixations is a fast and natural input method for VR interaction. Previous attempts for mobile eye tracking in VR were limited due to low accuracy, long processing time and the need for hardware add-ons such as anti-reflective lens coating and IR emitters. We present an innovative mobile VR eye tracking methodology, utilizing only the captured images of the front-facing (selfie) camera through the headset's lens, without any modifications. The system enhances the low-quality camera-captured images that suffer from low contrast and poor lighting by applying a pipeline of customized low level image enhancements to suppress obtrusive reflections due to the headset lenses. We proceed to calibration and linear gaze mapping between the estimated iris centroids and physical pixels on the screen resulting to iris tracking in real-time. A preliminary study confirms that the presented eye tracking methodology performs comparably to eye trackers in commercial VR headsets when the eyes move in the central part of the headset's field of view.http://creativecommons.org/licenses/by/4.0/642-6432020 IEEE Conference on Virtual Reality and 3D User Interfaces Abstracts and WorkshopsProceedings - 2020 IEEE Conference on Virtual Reality and 3D User Interfaces Drakopoulos Panagiotis Δρακοπουλος Παναγιωτης Koulieris Georgios-Alexandros Κουλιερης Γεωργιος-Αλεξανδρος Mania Aikaterini Μανια Αικατερινη Institute of Electrical and Electronics Engineers Eye-tracking Mobile VR Gaze-contingent displays
