  1. Multimodal AI Agents
    • AI models capable of interactively assisting users with daily tasks
    • Focus on proactive and cooperative engagement
  2. YET to Intervene (YETI) Multimodal Agent
    • Research focus
      • Identifying circumstances for proactive intervention
    • Purpose
      • Assist users in correcting mistakes during task execution
  3. Key Features of YETI
    • Scene understanding signals
      • Based on Structural Similarity Index Measure (SSIM) across video frames
    • Alignment signal
      • Tracks consistency of user actions with expected task actions (e.g., monitoring object count)
    • Algorithmic efficiency
      • On-the-fly computation reduces overhead while maintaining accuracy
  4. Proactive Communication in AI Agents
    • Intelligence
      • Anticipating task developments
    • Adaptivity
      • Adjusting intervention timing dynamically
    • Civility
      • Respecting user boundaries and ethical considerations
  5. Data Collection Framework
    • AR devices
      • Capture first-person task execution videos and expert guidance
  6. Interaction Types
    • Proactive interactions
      • High-level guidance, follow-up instructions, feedback, error correction
    • Reactive interactions
      • Expert responses to user queries and dialogues
  7. Signals for Proactive Intervention
    • Change in object count
      • Tracks user attention and task focus (e.g., pauses during instruction listening)
    • Temporal coherence
      • SSIM analysis identifies meaningful video frames for intervention
  8. Proactive Activities Categorization
    • Proactive interaction
      • Initiating engagement without user prompts (e.g., high-level instructions)
    • Proactive Intervention
      • Taking steps to alter user behavior (e.g., correcting errors)
    • Both
      • Follow-up instructions, confirming/correcting actions
  9. Enhanced Sensory Integration
    • Additional modalities
      • Hand pose, eye gaze, head orientation, IMU readings, depth data
    • Benefit
      • Comprehensive context understanding for nuanced intervention
  10. Use Cases
    • Assembly tasks
      • Examples: Assembling/disassembling furniture and equipment
    • Maintenance and repair
      • Examples: Fixing a motorcycle, changing mechanical belts
    • Consumer electronics
      • Examples: Setting up printers, cameras, coffee machines, gaming consoles
  11. Key Benefits of Proactive Intervention
    • Complexity management
      • Helps manage tasks that become complex due to mistakes
    • Safety considerations
      • Guides users to avoid harm during risky tasks
    • Bridging expertise gap
      • Acts as an instructor for novice users
