We introduce Ego4D, a massive-scale egocentric video dataset and benchmark suite. It offers 3,670 hours of dailylife activity video spanning hundreds of scenarios (household, outdoor, workplace, leisure, etc.) captured by 931 unique camera wearers from 74 worldwide locations and 9 different countries. The approach to collection is designed to uphold rigorous privacy and ethics standards, with consenting participants and robust de-identification procedures where relevant. Ego4D dramatically expands the volume of diverse egocentric video footage publicly available to the research community. Portions of the video are accompanied by audio, 3D meshes of the environment, eye gaze, stereo, and/or synchronized videos from multiple egocentric cameras at the same event. Furthermore, 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). By publicly sharing this massive annotated dataset and benchmark suite, we aim to push the frontier of first-person perception.

Undergraduate research and graduate mentoring have received a great deal of attention in recent times. What do these activities have in common? They both speak to the primary mission of the research university, which is not merely carrying out research but training students to do research. The knowledge-based global economy, with its wealth of information and opportunities, has increased undergraduate students' need for research skills as well as graduate students' desire for personal guidance. As the research university matures, the boundaries between graduate and undergraduate education are blurring. Indeed, if we focus on the learning process, we find not two but five levels of learning at the research university: lower division, upper division, master's, doctoral, and postdoctoral. All five levels form a continuum, a series of gradual steps. The mission of the university is to introduce students to research, to inspire in them a passion for discovery at each of these levels.
