This study investigated the effects of wearing a head-mounted eye tracker on upright balance during different visual tasks. Twenty five young adults stood upright on a force plate while performing the visual tasks of fixation, horizontal saccades, and eyes closed, during eighteen trials wearing or not a head-mounted eye tracker. While wearing the eye tracker, participants showed a reduction in mean sway amplitude and velocity of the CoP in the AP and ML directions and more regular CoP fluctuations, in the ML axis in all conditions. Higher mean sway amplitude and velocity of CoP were observed during eyes closed than fixation and saccades. Moreover, horizontal saccades reduced mean sway velocity of CoP compared to fixation. Therefore, wearing the eye tracker minimized the body sway of young adults; however, visual task-related effects on postural stability remained unchanged.
本研究调查了在不同视觉任务中佩戴头戴式眼动仪对直立平衡的影响。二十五名年轻成年人在力板上直立，同时进行注视、水平扫视和闭眼等视觉任务，共进行十八次试验，分别佩戴和不佩戴头戴式眼动仪。佩戴眼动仪时，参与者在 AP 和 ML 方向的 CoP 平均摆动幅度和速度以及 ML 轴上的 CoP 波动更规则，在所有条件下。闭眼时 CoP 的平均摆动幅度和速度均高于注视和扫视。此外，水平扫视与注视相比降低了 CoP 的平均摆动速度。因此，佩戴眼动仪可以最小化年轻人的身体晃动；然而，与姿势稳定性相关的视觉任务影响仍然不变。
