Tianxing Li, Qiang Liu, Xia Zhou · 2017
Tracking user's eye fixation direction is crucial to virtual reality (VR): it eases user's interaction with the virtual scene and enables intelligent rendering to improve user's visual experiences and save system energy. Existing techniques commonly rely on cameras and active infrared emitters, making them too expensive and power-hungry for VR headsets (especially mobile VR headsets).
