目的是一种有效的手段，以提高检测到的固定的准确性。背景是研究佩戴眼动仪的受试者在观察远处物体时的自然行为。注视检测算法试图确定视网膜上的图像何时稳定。可穿戴眼动仪的先前算法仅考虑头中眼运动。然而，在前庭眼反应（VOR）的存在下，头部的运动抵消了头中眼的旋转。补偿这种自我运动增加了所有受试者检测到的注视的数量。这种补偿显著影响检测到的注视的数量和大小，更准确地反映了移动的观察者的自然注视行为。
The objective is an efficient means to improve the accuracy of detected fixations. The context is studies of natural behavior of subjects wearing eye trackers while observing distant objects. Fixation detection algorithms try to determine when the image on the retina is stable. Previous algorithms for wearable eye trackers consider only eye-in-head motion. In the presence of the vestibular-ocular response (VOR), however, the motion of the head counteracts eye-in-head rotation. Compensating for this ego-motion increases the number of detected fixations for all subjects. This compensation significantly affects the number and size of the fixations detected, more accurately reflecting mobile observers' natural gaze behavior.
