When an object moves in three dimensions, the two eyes' views of the world deliver slightly different information to the visual system, providing binocular cues to depth and motion-in-depth. This short review describes the two main sources of binocular information, namely, changing disparity over time and interocular velocity differences; this could be used for the perception of motion-in-depth. We discuss the evidence obtained in recent years on the extent to which each of them is used in human vision. We also highlight outstanding questions and issues in the field that have yet to be addressed.
当一个物体在三维空间中移动时，两只眼睛对世界的视图会向视觉系统传递略有不同的信息，从而提供有关深度和深度运动的双眼线索。这篇简短的综述描述了双眼信息的两个主要来源，即随时间变化的视差和两眼间速度差异；这些信息可用于深度运动感知。我们讨论了近年来获得的关于它们在人类视觉中各自被利用程度的证据。我们还强调了该领域尚未解决的突出问题。
