  In recent years, head-mounted near-eye display devices have become the key
hardware foundation for virtual reality and augmented reality. Thus
head-mounted gaze tracking technology has received attention as an essential
part of human-computer interaction. However, unavoidable slippage of
head-mounted devices (HMD) often results higher gaze tracking errors and
hinders the practical usage of HMD. To tackle this problem, we propose a
slippage-robust gaze tracking for near-eye display method based on the aspheric
eyeball model and accurately compute the eyeball optical axis and rotation
center. We tested several methods on datasets with slippage and the
experimental results show that the proposed method significantly outperforms
the previous method (almost double the suboptimal method).
