A method for automatically decomposing complex robotic manipulation tasks into sub-tasks is presented, leveraging human gaze transitions during teleoperation and a refinement process to ensure consistent segmentation across demonstrations. This approach leads to more robust imitation learning, achieving higher task success rates in novel configurations.
Key insights
- Human gaze provides a robust and intuitive signal for identifying sub-task boundaries during object manipulation, as it naturally correlates with task-relevant landmarks and cognitive shifts.
- Enforcing a consistent number of sub-tasks across multiple demonstrations for the same task, through an adaptive refinement mechanism, is crucial for improving the reliability and reusability of learned skills.
- The combination of gaze position and visual feature changes offers a comprehensive signal for task transitions, with gaze position proving to be the more critical component for robust segmentation.
