Why first person video may matter for robot learning[D]

I can see why first-person video might help a robot model, but not because the robot can copy a human hand. The joints, reach, timing, and control space are all different. What may transfer is the sequence of visual attention: which object enters view, what changes before contact, and where the actor looks next. LingBot-VLA 2.0 (arXiv:2607.06403) uses first-person data alongside robot trajectories. A useful ablation separates visual prediction from robot control. First-person pretraining might improve next-state prediction without improving task success, which would still tell us where the information survived. A matched third-person comparison is important too, otherwise viewpoint and video volume are mixed together. Occlusion is the obvious problem. Hands often cover the object at the exact moment of contact. Would you treat those frames as useful evidence of intent, missing visual data, or both? I have not seen a convincing evaluation that cleanly separates those effects.
