  1. Interaction-Shaping Robotics
    • A subfield of HRI focused on robots influencing interactions between two or more agents
    • Key aspects
      • Role of robot
      • Robot-shaping outcomes
      • Form of influence
      • Type of communication
      • Influence timeline
  2. Effects of Robot Behavior
    • Direct Reciprocal Effect
      • Traditional HRI scenarios where the robot influences human behaviors back toward itself
    • Indirect Effect
      • Unique to Interaction-Shaping Robotics, where the robot shapes the interaction or perception between agents in a group
  3. Key Factors in ISR
    • Role of Robot
      • Guiding Facilitator: Actively mediates interaction
      • Peripheral Facilitator: Active but not directly involved
      • Peer Group Member: Participates as a peer
      • Specialized Group Member: Assumes a specific role
    • Robot-Shaping Outcomes
      • Cognitive: Influences attitudes, evaluations, and intentions
      • Behavioral: Affects actions like speaking or spatial positioning
    • Form of Robot Influence
      • Explicit: Direct communication (e.g., conflict resolution)
      • Implicit: Subtle cues shaping interaction (e.g., gestures)
    • Type of Robot Communication
      • Verbal: Natural language
      • Non-Verbal: Gestures, gaze, movements
    • Timeline of Influence
      • Immediate: Real-time interaction shaping
      • Long-Lasting: Post-interaction effects
  4. Communication Capabilities of Robots
    • Beyond human abilities: Use of lights, sounds, and movements unique to robots
    • Example structures
      • Single robot influencing human-human interaction
      • Single robot in human-robot interaction
      • Multiple robots influencing group interactions
  5. Ethical Considerations in Interaction-Shaping Robotics
    • Reducing Risks
      • Dependency: Robots aim to sustainably improve interactions, eventually becoming obsolete
      • Deception: Balancing awareness and ethical use of influence, following IEEE guidelines
    • Bias Mitigation
      • Risks from societal and dataset biases, particularly in machine learning-based behaviors
    • Awareness Spectrum
      • Varies from fully aware to unaware, influenced by non-verbal communication or robot roles
  6. Social Dynamics and Group Influence
    • Leveraging and inducing group phenomena like social cohesion
    • Importance of modeling relationships and group factors in human-robot interaction
    • Bridging Social Signal Processing (SSP) and ISR for improved perception and interaction modeling
  7. Technological Pathways
    • Graph Abstractions
      • Encoding interactants and relationships as nodes and edges for structured data representation
    • Learning Algorithms
      • Reinforcement Learning and Imitation Learning for mapping group states to effective behaviors
      • Early exploration: Balancing participation in conversations.
  8. Future Directions
    • Enhancing Interaction-shaping robotics perception and control loops
    • Developing algorithms that address ethical, social, and technical challenges
    • Advancing methodologies to sustain and enrich human interactions and relationships
