Summary

Detect facial expressions to adapt robot conversation tone and responses.

Requirements

  • Expression classifier: 7 basic emotions (happy, sad, angry, surprised, fearful, disgusted, neutral)
  • Model: Lightweight CNN on TensorRT FP16 (face crop from SCRFD → expression classifier)
  • Per-person tracking: Track emotional state per person_id over time
  • Conversation adaptation: Feed emotion state to LLM context (e.g., be gentler if person seems sad)
  • ROS2 topics: /social/faces/expressions (Expression msg with person_id + emotion + confidence)
  • Privacy: Process on-device only, no cloud upload, optional opt-out per person
  • Performance: Piggyback on existing face detection pipeline, <5ms additional latency
