Contact Imitation Interface: Transferring Dexterous Skills by Showing How Contact Unfolds
Contact Imitation Interface: Transferring Dexterous Skills by Showing How Contact Unfolds
This research presents Contact Imitation Interface (CIMI), a framework for robot-free human demonstrations that preserves natural dexterity while generating contact-grounded observations and actions transferable to robot hands. The system combines shared contact geometry, fingertip RGB views, and contact-alignment-first retargeting in its demonstration interface, alongside a hierarchical policy with a contact-surface planner and wrist/finger controller in its learning interface. Evaluated on six hand-task pairs using the LEAP and Wuji platforms, CIMI improves mean final-stage success by at least 50 percentage points over baseline policies. Hardware designs and software are publicly available.
The paper introduces a robot-free demonstration framework that transfers dexterous manipulation skills by aligning contact geometry and fingertip views, reporting at least 50 percentage point improvement in success rates across six hand-task pairs on the LEAP and Wuji platforms.
