Abstract Synopsis

  • Large language models are advancing robotic verbal communication, but humanoid robots still struggle with nonverbal cues, particularly facial expressions.
  • The main challenges include the mechanical complexity of creating an expressive robotic face and accurately determining appropriate expressions to convey naturalness and genuineness.
  • The proposed solution involves training robots to predict human facial expressions, allowing them to coexpress emotions in sync with humans, which has the potential to enhance the quality of human-robot interactions significantly.
