Many of the tasks we perform on a daily basis, such as reaching for and manipulating objects, rely on naturally occurring eye movements that gather relevant visual information to guide one’s actions. Past research has shown that gaze supports such tasks by fixating target objects as the hand approaches, and then shifting to the next target object at around the time the hand arrives. Whereas research to date has focused on tasks performed in isolation, real world scenarios are much more complex: we frequently engage in multi-tasking—e.g., we perform an action while monitoring a visual scene or perform two actions simultaneously—both of which require accurate visual control. Because our eyes can only be directed to a single point in space at any given time, the challenge for the visual system is to efficiently allocate gaze in a way that maintains accurate sensorimotor control of ongoing actions. The proposed research program aims to better understand how people are able to maintain successful motor performance in dynamic and complex visual environments. More specifically, the goal is to comprehend how eye and hand movements are coordinated to optimize visual and motor control in real-world actions by identifying the critical functions and limitations of gaze and its interdependence with motor control.

我们每天执行的许多任务，例如伸手去拿和操纵物体，都依赖于自然发生的眼球运动，这些眼球运动收集相关的视觉信息来指导我们的行动。过去的研究表明，凝视通过在手接近时固定目标物体，然后在手到达的时候转移到下一个目标物体来支持这些任务。尽管迄今为止的研究集中在孤立执行的任务上，但真实的世界场景要复杂得多：我们经常从事多任务处理-例如，我们在监视视觉场景的同时执行一个动作，或者同时执行两个动作，这两个动作都需要精确的视觉控制。因为我们的眼睛在任何给定的时间只能指向空间中的一个点，视觉系统面临的挑战是以一种保持对正在进行的动作的准确感觉运动控制的方式有效地分配凝视。该研究计划旨在更好地了解人们如何在动态和复杂的视觉环境中保持成功的运动表现。更具体地说，我们的目标是理解眼睛和手的运动是如何协调的，以优化视觉和运动控制在现实世界的行动，通过识别的关键功能和限制的凝视及其相互依存关系与运动控制。
