空间记录允许观众在其中移动并自由选择他们的观点。然而，这样的记录很容易错过事件，并且在跳过记录时很难跟随移动的对象。为了缓解这些问题，我们提出了谁把有系统，允许用户通过直接操纵场景中的对象，通过时间导航。通过选择对象，用户可以导航到对象改变的时刻。用户还可以查看改变位置的对象的轨迹，并直接操纵它们进行导航。我们在有声思维研究中用一组意义建构问题对该系统进行了评估。参与者了解该系统，并发现它有助于在现场和参与记录的同时找到感兴趣的事件。
Spatial recordings allow viewers to move within them and freely choose their viewpoint. However, such recordings make it easy to miss events and difficult to follow moving objects when skipping through the recording. To alleviate these problems we present the Who Put That There system that allows users to navigate through time by directly manipulating objects in the scene. By selecting an object, the user can navigate to moments where the object changed. Users can also view trajectories of objects that changed location and directly manipulate them to navigate. We evaluated the system with a set of sensemaking questions in a think-aloud study. Participants understood the system and found it useful for finding events of interest, while being present and engaged in the recording.
