Table_1_Quiet Eye and Computerized Precision Tasks in First-Person Shooter Perspective Esport Games.DOCX

The gaze behavior in sports and other applied settings has been studied for more than 20 years. A common finding is related to the “quiet eye” (QE), predicting that the duration of the last fixation before a critical event is associated with higher performance. Unlike previous studies conducted in applied settings with mobile eye trackers, we investigate the QE in a context similar to esport, in which participants click the mouse to hit targets presented on a computer screen under different levels of cognitive load. Simultaneously, eye and mouse movements were tracked using a high-end remote eye tracker at 300 Hz. Consistent with previous studies, we found that longer QE fixations were associated with higher performance. Increasing the cognitive load delayed the onset of the QE fixation, but had no significant influence on the QE duration. We discuss the implications of our results in the context of how the QE is defined, the quality of the eye-tracker data, and the type of analysis applied to QE data.

体育及其他应用场景中的注视行为研究已开展二十余年。学界普遍存在一项与“静眼（quiet eye, QE）”相关的共识性发现：其核心论断为，关键事件发生前的最后一次注视时长与更优的任务表现存在关联。与此前依托移动眼动仪开展的应用场景研究不同，本研究在类电竞情境下探究静眼效应：受试者需在不同认知负荷水平下，通过鼠标点击计算机屏幕上呈现的目标。实验过程中，我们采用采样率为300 Hz的高端远程眼动仪同步记录眼部与鼠标运动轨迹。与既往研究结果一致，本研究发现更长时长的静眼注视与更优的任务表现显著相关。提升认知负荷会延迟静眼注视的触发时机，但对静眼注视的持续时长无显著影响。最后，我们结合静眼的定义范式、眼动仪数据质量以及静眼数据的分析方法，对本研究结果的应用启示展开讨论。
