The same motion means entirely different things across different identities, relationships, and settings.
Our work on embodied social intelligence asks how AI can understand a shared situation. We study an embodied social world model through robot interaction and simulation: people's goals, roles and relationships matter alongside space, objects and motion.
It has to help the robot answer three questions: What is happening right now? What might happen next? How should I take part?
These questions rarely have a single answer. A robot has to keep judging under incomplete information, update its understanding as new evidence arrives, and actively ask people to confirm when uncertainty runs too high.
