MMHOI Dataset: Modeling Complex 3D Multi-Human Multi-Object Interactions for fostering research in multi-human multi-object interactions and serving as a benchmark for next-generation HOI algorithms.

The MMHOI dataset addresses the challenge of modeling real-world scenes with multiple humans and objects interacting in causal, goal-oriented, or cooperative ways. Existing 3D human-object interaction (HOI) benchmarks capture only a subset of these complex interactions. MMHOI closes this gap by providing a large-scale dataset with comprehensive 3D shape and pose annotations for every person and object, covering 78 action categories and 14 interaction-specific body parts across 12 everyday scenarios.

MMHOI is designed to foster research in multi-human multi-object interactions and serves as a benchmark for next-generation HOI algorithms. All necessary data for training, validation, and testing are publicly released.
