## Summary

The paper proposes the PointHand teleoperation interface, which renders a multi-fingered robotic hand as sparse keypoints at the fingertips and joints, matching the keypoints observable by the policy. In a simulated mug-in-box task, 18 novices and 4 experts collected 2,200 trials across three rendering conditions; among them, novices who saw emphasized rendering of the thumb and index finger achieved 441 successful demonstrations out of 600 trials, higher than the 320 out of the real hand-shape rendering.
