arXiv:2606.02962v1 Announce Type: cross Abstract: Egocentric Natural Language Query (NLQ) grounding asks a model to localize, in a long first-person video, the temporal interval that answers a free-form text query. Existing methods fuse video appearance with the query but ignore hand motion, despite the fact that roughly 41% of Ego4D NLQ queries are answered at a moment of hand--object manipulation or their immediate outcomes.We propose a hand-trajectory encoder for converting a sequence of hand skeletons into highly-semantic hand kinematic features, which are then aligned and combined with pr
This paper leverages improved egocentric video datasets and advancements in multimodal AI, addressing a key limitation in current natural language query grounding by incorporating hand motion.
Improving the ability of AI to understand and respond to natural language queries in complex, real-world egocentric video environments is crucial for advancing human-robot interaction and agentic systems.
AI models can now more accurately understand user intent by integrating hand kinematics, particularly in tasks involving manipulation, leading to more responsive and context-aware systems.

More accurate and natural human-AI interaction in egocentric environments becomes possible.
This could accelerate the development of advanced AI agents capable of complex physical tasks and instruction following.
Improved contextual understanding via hand movements might lead to new ergonomic designs for AI-assisted tools and interfaces, influencing future industrial and consumer products.
