The idea
Compare shared room scans to find what moved, disappeared, or arrived, then use ghosted earlier positions to restore an arrangement.
How it works
- Scan the same room at different times and align the spatial records.
- Compare surfaces and objects to identify additions, removals, or moved items.
- Show a ghost of an earlier arrangement as a guide for movers, contractors, or film continuity.
AI’s role: Describe likely object changes and make a room history searchable; scan registration and change detection still need geometric validation.
First demonstration
Scan a room before and after moving a lamp and chair. Highlight the changed objects and show their earlier positions as translucent guides.
What to solve next
How should the system distinguish a meaningful change from scan noise, lighting changes, or an object temporarily out of view?
