HÄSLER & ACKERMANN · RESEARCH PROTOTYPE

An inspectable 3D inference
pipeline for XR applications.

The apparatus derives searchable spatial attributes and predicate relations from measured oriented bounding boxes. Every query is an explicit SRpy pipeline; every result remains traceable to object IDs, geometry, and server-side predicate evaluation.

Method boundary Oriented-bounding-box inference with configurable spatial fuzziness; no physics, occlusion solver, or motion-planning safety claim. Tabletop overlaps are user-managed; the observer is constrained by walls and floor furniture.
