Text, Touch and Trajectories: Reconstructing 3D Humans with 3T’s

3D human reconstruction requires more than just modeling geometry - it demands a nuanced understanding of semantics, contacts, and motions. This talk explores how we can rethink reconstruction through the lens of 3Ts: Text, Touch, and Trajectories, as three complementary signals to infer human and object structures in the wild. Text, or natural language, provides an intuitive prior for object shape and category and we use it as support for hand-object reconstruction. Touch, or contact, provide cues that link humans to the outside world. I will introduce our state-of-the-art approach on world-coordinate human mesh recovery based on inferred contact points such as the feet or the hands. Finally, trajectories capture how the body moves through space, both locally and globally. I will describe how we use whole-body momentum as a physically grounded constraint to relate joint-level dynamics to global displacement.
