SpatialTrace turns video into searchable visual memory. Instead of scrubbing through a recording to find a misplaced item or check when something moved, users can ask questions such as “Where did I last see my glasses?”, “When did the laptop first appear?”, or “Did the mug move?”

Users upload a video or capture a browser camera session. SpatialTrace samples frames, describes their contents, and builds a local index. When a question is asked, it searches relevant observations and verifies candidate objects using Meta’s Muse Spark and SAM models.

Answers include timestamped frames, object outlines, segmentation masks, and a sightings timeline, giving users evidence they can inspect. When the available footage is incomplete or ambiguous, SpatialTrace reports uncertainty.

The project addresses the gap between recording an event and finding useful information in it. It helps people revisit desk, room, or workspace recordings without manually reviewing the entire video. Sampling and cached model responses reduce repeated processing, while saved footage and search history remain in local storage.

SpatialTrace is a visual memory assistant: it reports what was verified in saved observations, rather than assuming an object is still there now.
