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.
