在球类运动中，人们通常认为，专业运动员比新手更准确地跟踪球。然而，也有证据表明，保持眼睛对球并不总是必要的拦截。在这里，我们的目的是获得新的见解在何种程度上，眼睛的追求性能相关的捕捉性能。为此，我们分析了9个受试者的眼睛和头部运动捕捉一个球投射的驱动发射装置。四个不同的球飞行持续时间和两个不同的球到达高度进行了测试和质量的眼睛追求的特点是通过几个时间和精度参数。接球表现在不同的科目，并取决于球的飞行特性。所有受试者都表现出类似的眼球运动事件序列，以及这些事件与球轨迹特征相关的时间的类似调制。在一个试验的基础上，只有追逐持续时间和接球表现之间存在显着的关系，证实了眼睛盯着球的时间越长，接球成功的概率就越高。眼睛追踪参数值及其对飞行条件的依赖性以及眼睛和头部对注视转移的贡献在受试者中不同。然而，观察到的平均个人的眼睛行为和眼头协调模式没有直接关系到个人的捕捉性能。这些结果表明，几种眼动策略可以用来收集球运动的信息，以及与眼球运动无关的因素可能是所观察到的拦截性能差异的基础。
In ball sports, it is usually acknowledged that expert athletes track the ball more accurately than novices. However, there is also evidence that keeping the eyes on the ball is not always necessary for interception. Here we aimed at gaining new insights on the extent to which ocular pursuit performance is related to catching performance. To this end, we analyzed eye and head movements of nine subjects catching a ball projected by an actuated launching apparatus. Four different ball flight durations and two different ball arrival heights were tested and the quality of ocular pursuit was characterized by means of several timing and accuracy parameters. Catching performance differed across subjects and depended on ball flight characteristics. All subjects showed a similar sequence of eye movement events and a similar modulation of the timing of these events in relation to the characteristics of the ball trajectory. On a trial-by-trial basis there was a significant relationship only between pursuit duration and catching performance, confirming that keeping the eyes on the ball longer increases catching success probability. Ocular pursuit parameters values and their dependence on flight conditions as well as the eye and head contributions to gaze shift differed across subjects. However, the observed average individual ocular behavior and the eye-head coordination patterns were not directly related to the individual catching performance. These results suggest that several oculomotor strategies may be used to gather information on ball motion, and that factors unrelated to eye movements may underlie the observed differences in interceptive performance.
