凝视深度估计对3D中的眼睛跟踪提出了挑战。这项工作探讨了一种新的方法来解决这个问题的基础上，由前庭眼反射（VOR）介导的眼球运动。VOR在头部移动期间稳定对目标的注视，而眼睛在相反方向上移动，并且VOR增益增加，固定目标离观看者越近。我们提出了一个理论分析VOR增益和深度之间的关系，我们调查的经验数据收集的用户研究（N=10）。我们表明，VOR增益可以使用瞳孔中心捕获，并提出和评估一个实用的方法，凝视深度估计的基础上的通用函数的VOR增益和两点深度校准。结果表明，VOR增益在捕获深度方面与聚散度相当，同时仅需要一只眼睛，并提供了对利用VOR增益作为稳健测量的开放挑战的深入了解。
Gaze depth estimation presents a challenge for eye tracking in 3D. This work investigates a novel approach to the problem based on eye movement mediated by the vestibulo-ocular reflex (VOR). VOR stabilises gaze on a target during head movement, with eye movement in the opposite direction, and the VOR gain increases the closer the fixated target is to the viewer. We present a theoretical analysis of the relationship between VOR gain and depth which we investigate with empirical data collected in a user study (N=10). We show that VOR gain can be captured using pupil centres, and propose and evaluate a practical method for gaze depth estimation based on a generic function of VOR gain and two-point depth calibration. The results show that VOR gain is comparable with vergence in capturing depth while only requiring one eye, and provide insight into open challenges in harnessing VOR gain as a robust measure.
