EgoGen: An Egocentric Synthetic Data Generator

EgoGen is a synthetic data generator designed for egocentric perception tasks, producing accurate ground‑truth training data by simulating natural human movements that steer virtual cameras. Its core is a human motion synthesis model that uses egocentric visual inputs to sense 3D environments, combined with collision‑avoiding motion primitives and a two‑stage reinforcement learning approach for closed‑loop perception and movement. The system eliminates the need for pre‑defined global paths, works in dynamic settings, and supports tasks such as mapping, localization, camera tracking, and human mesh recovery from first‑person views.

EXPLORE-Bench: Egocentric Scene Prediction with Long-Horizon Reasoning

arXiv:2603. 09731v3 Announce Type: replace-cross Abstract: Multimodal large language models (MLLMs) are increasingly considered as a foundation for embodied agents, yet it remains unclear whether they can reliably reason about the long-term physical consequences of actions from an egocentric viewpoint.

MINT: A Unified Model for World-Space Camera and Hand Motion Estimation from Scalable Egocentric Pipeline Supervision

MINT is a foundation model that directly predicts world-space two-hand trajectories from egocentric RGB video, jointly estimating camera motion, hand states, and hand presence in a single spatiotemporal representation. It uses an open-source labeling pipeline, EGOPIPELINE, to generate large-scale pseudo-labels for pretraining, followed by fine-tuning on a small set of high-quality joint annotations. The model outperforms existing multi-stage approaches in accuracy and speed, and generalizes zero‑shot to unseen egocentric datasets.
