When we catch a moving object in mid-flight, our eyes and hands are directed toward the object. Yet, the functional role of eye movements in guiding interceptive hand movements is not yet well understood. This review synthesizes emergent views on the importance of eye movements during manual interception with an emphasis on laboratory studies published since 2015. We discuss the role of eye movements in forming visual predictions about a moving object, and for enhancing the accuracy of interceptive hand movements through feedforward (extraretinal) and feedback (retinal) signals. We conclude by proposing a framework that defines the role of human eye movements for manual interception accuracy as a function of visual certainty and object motion predictability.
当我们在半空中捕捉移动物体时，我们的眼睛和手会朝向物体。然而，眼睛运动在引导拦截性手部运动中的功能作用尚不清楚。本综述综合了在手动拦截过程中眼睛运动的重要性的新观点，重点介绍了自 2015 年以来发表的实验室研究。我们讨论了眼睛运动在对移动物体形成视觉预测以及通过前馈（视网膜外）和反馈（视网膜内）信号提高拦截手运动准确性方面的作用。最后，我们提出了一个框架，将人类眼睛运动在手动拦截准确性方面的作用定义为视觉确定性和物体运动可预测性的函数。
