CHOIR: Contact-aware 4D Hand-Object Interaction Reconstruction
arXiv CS.CV

ArXi:2605.20992v1 Announce Type: new We ask whether everyday open-world monocular videos can be turned into reusable 4D interaction primitives: articulated hand motion, object shape with 6D pose over time, and the when/where of contact. Such a capability would enable scalable mining of real interactions and, beyond reconstruction, scene-aware synthesis and planning.
