Summary

Fusion node: face + voice + position into unified person state.

Requirements

  • Identity fusion: Match face_id + speaker_id + UWB position into single person_id
  • State tracking: Per-person state machine (approaching, engaged, talking, leaving, absent)
  • Multi-camera: Track across 4 CSI cameras with FOV handoff
  • Attention model: Who should robot focus on (closest, loudest, most engaged)
  • ROS2 topics: /social/persons (PersonArray with id, name, position, state, attention_score)
  • Persistence: Remember known persons across sessions
  • Group dynamics: Detect group vs 1:1 interaction
