Nymeria (Meta Reality Labs, ECCV 2024, arXiv 2406.09905) is a large egocentric human-motion dataset: 300 h of daily activities from 264 participants in 50 locations. Participants wear Project Aria glasses and a miniAria wristband on each wrist, and an XSens MVN Link suit records full-body pose as ground truth. The dataset also has hierarchical language narrations. NymeriaPlus (arXiv 2603.18496) extends it.
