Decoding Self-Handover Behaviors
First Systematic Taxonomy of How Humans Transfer Objects Between Their Hands
This research presents the first comprehensive classification system for self-handover – the understudied yet common action of transferring objects between one's own hands during complex tasks.
- Based on analysis of 12+ hours of cooking activities from 21 participants
- Reveals self-handover as a highly coordinated action, not merely a passive transition
- Identifies distinct patterns and strategies humans employ during bimanual transfers
- Provides foundational insights for improving dual-arm robotic systems
For engineering teams, this taxonomy offers critical design principles for robotics that require human-like dexterity and coordination, particularly in cooking and manipulation tasks.
