多对象跟踪中的空间参考可通过动态对象和静态参考对象的配置获得。在三个实验中，我们研究了空间参考在场景突然旋转后跟踪和重新定位目标中的使用。观察者在 3D 场景中跟踪 1、2、3、4 和 6 个目标，其中白球在方形地板上移动。地板平面要么是可见的，从而提供静态空间参考，要么是不可见的。如果没有场景旋转，动态对象的配置提供了足够的空间参考，而静态空间参考则没有优势。相比之下，场景突然旋转 20° 时，静态空间参考支持重新定位目标。缺乏局部视觉细节的线框地板平面与棋盘一样有效。即使目标在突然的场景旋转时以这些形状为中心，单独着色的几何形状作为静态参考对象也没有提供额外的好处。然而，在突然的场景旋转周围的短暂间隔内通过颜色来个性化动态对象本身确实提高了性能。我们得出的结论是，运动目标的注意力跟踪是在动态配置中进行的，但与静态局部背景无关。
Spatial reference in multiple object tracking is available from configurations of dynamic objects and static reference objects. In three experiments, we studied the use of spatial reference in tracking and in relocating targets after abrupt scene rotations. Observers tracked 1, 2, 3, 4, and 6 targets in 3D scenes, in which white balls moved on a square floor plane. The floor plane was either visible thus providing static spatial reference or it was invisible. Without scene rotations, the configuration of dynamic objects provided sufficient spatial reference and static spatial reference was not advantageous. In contrast, with abrupt scene rotations of 20°, static spatial reference supported in relocating targets. A wireframe floor plane lacking local visual detail was as effective as a checkerboard. Individually colored geometric forms as static reference objects provided no additional benefit either, even if targets were centered on these forms at the abrupt scene rotation. Individualizing the dynamic objects themselves by color for a brief interval around the abrupt scene rotation, however, did improve performance. We conclude that attentional tracking of moving targets proceeds within dynamic configurations but detached from static local background.
