在环境中行走会产生视网膜运动，人类依靠视网膜运动来执行各种视觉任务。视网膜运动模式由一组相互关联的因素决定，包括注视位置、注视稳定性、环境结构和步行者的目标。这些运动信号的特征对神经组织和行为具有重要影响。然而，迄今为止，还没有经验性的现场测量组合的眼睛和身体运动如何与真实的3D环境相互作用以形成视网膜运动信号的统计。在这里，我们收集了运动过程中眼睛、身体和3D环境的测量结果。我们描述所得到的视网膜运动模式的属性。我们解释了这些模式是如何通过世界上的凝视位置以及行为来塑造的，以及它们如何为运动敏感度和感受野特性在整个视野中的变化提供模板。
Walking through an environment generates retinal motion, which humans rely on to perform a variety of visual tasks. Retinal motion patterns are determined by an interconnected set of factors, including gaze location, gaze stabilization, the structure of the environment, and the walker’s goals. The characteristics of these motion signals have important consequences for neural organization and behavior. However, to date, there are no empirical in situ measurements of how combined eye and body movements interact with real 3D environments to shape the statistics of retinal motion signals. Here, we collect measurements of the eyes, the body, and the 3D environment during locomotion. We describe properties of the resulting retinal motion patterns. We explain how these patterns are shaped by gaze location in the world, as well as by behavior, and how they may provide a template for the way motion sensitivity and receptive field properties vary across the visual field.
