HOI-Ref: Hand-Object Interaction Referral in Egocentric Vision

We propose the HOI-Ref task to understand hand-object interaction using Vision Language Models (VLMs). We introduce the HOI-QA dataset with 3.9M question-answer pairs for training and evaluating VLMs. Finally, we train the first VLM for HOI-Ref, achieving state-of-the-art performance.

Ego-Exo4D: Understanding Skilled Human Activity from First- and Third-Person Perspectives

Ego-Exo4D is a diverse, large-scale multi-modal, multi-view, video dataset and benchmark collected across 13 cities worldwide by 839 camera wearers, capturing 1422 hours of video of skilled human activities.
We present three synchronized natural language datasets paired with videos. (1) expert commentary, (2) participant-provided narrate-and-act, and (3) one-sentence atomic action descriptions.
Finally, our camera configuration features Aria glasses for ego capture which is time-synchronized with 4-5 (stationary) GoPros as the exo capture devices.

United We Stand, Divided We Fall: UnityGraph for Unsupervised Procedure Learning from Videos

We propose Graph-based Procedure Learning (GPL) framework for procedure learning. GPL creates novel UnityGraph that represents all the task videos as a graph to encode both intra-video and inter-videos context. We achieve an improvement of 2% on third-person datasets and 3.6% on EgoProceL.

An Outlook into the Future of Egocentric Vision

The survey looks at the difference between what we’re studying now in egocentric vision and what we expect in the future. We imagine the future using stories and connect them to current research. We highlight problems, analyze current progress, and suggest areas to explore in egocentric vision, aiming for a future that’s always on, personalized, and improves our lives.

My View is the Best View: Procedure Learning from Egocentric Videos

We propose the EgoProceL dataset consisting of 62 hours of videos captured by 130 subjects performing 16 tasks and a self-supervised Correspond and Cut (CnC) framework for procedure learning. CnC utilizes the temporal correspondences between the key-steps across multiple videos to learn the procedure.

Ego4D: Around the World in 3,000 Hours of Egocentric Video

We offer 3,670 hours of daily-life activity video spanning hundreds of scenarios captured by 931 unique camera wearers from 74 worldwide locations and 9 different countries.
We present a host of new benchmark challenges centered around understanding the first-person visual experience in the past (querying an episodic memory), present (analyzing hand-object manipulation, audio-visual conversation, and social interactions), and future (forecasting activities).
