What they did and found
A brief in-scene action clip is fed to a world-like model. This helps tie forecasts to real scene movement, improving accuracy without extra physics labels or deep retuning. The prompt anchors predictions to actual dynamics.
Why it matters
For new spaces, collecting a short scene cue before planning can significantly reduce errors when physical rules vary.
A short in-scene prompt lets the predictive model tie forecasts to how items move in that setting, instead of using generic visuals alone.
The approach is lightweight and avoids physics labels, but accuracy may drop if the scene changes or cues weaken. Will prompts still guide forecasts if things shift?
What remains uncertain
Assumes scene rules stay the same during the task and that the cue provides informative signals.
