ChaLearn UDIVA-HHOI Challenge. ChaLearn announces the UDIVA-HHOI Challenge at ECCV 2026, focusing on context-aware human behavior understanding

The ChaLearn UDIVA-HHOI Challenge at ECCV 2026 is now open for registration. This challenge focuses on advancing research in context-aware human behavior understanding, emphasizing how people interact, coordinate, and influence one another in real-world settings.

Participants will work with the new UDIVA-HHOI dataset, a multimodal, multi-view dataset of non-scripted dyadic interactions in a collaborative assembly task. The challenge features 5 tracks:

• Track 1: Multimodal Exocentric Event Recognition
• Track 2: Multimodal Egocentric Event Recognition
• Track 3: Multimodal Exocentric Event Anticipation
• Track 4: Multimodal Egocentric Event Anticipation
• Track 5: Multimodal Exocentric Causal Event Grounding
