This paper explores how an embodied AI agent can act as a coach that accelerates human motor-skill development using reinforcement learning. The authors argue that effective coaching requires dynamically balancing guidance with learner autonomy — too much assistance leads to Over Reliance and skill atrophy, while too little leaves learners struggling.

Key findings:

  • An RL-based coaching policy that adapts its level of intervention to the learner's current skill level significantly accelerates skill acquisition compared to static assistance levels.
  • The AI coach that gradually fades scaffolding (consistent with Scaffolding theory in Intelligent Tutoring) produced the best long-term retention and transfer performance.
  • Over-reliance emerged when the coach provided excessive intervention, confirming the Over Reliance concern documented in Generative AI tutoring contexts.

    • Implications:

  • RL-based coaching offers a principled framework for personalized skill development in domains beyond traditional academics (e.g., surgical training, Professional Training, STEM lab skills).
  • The competence-based fading policy mirrors established pedagogical best practices, suggesting Formative Assessment signals can drive AI coaching adaptation.
  • Extends AI safety in tutoring research to embodied/motor skill domains.
