| # CoRoleHOI Dataset
|
|
|
| ## Overview
|
|
|
| **CoRoleHOI** is a dataset for **role-asymmetric multi-person multi-object Human–Object Interaction (HOI)**.
|
|
|
| It is designed to support research in:
|
| - Text-driven motion generation
|
| - Multi-person interaction modeling
|
| - Human-object interaction understanding
|
| - Embodied AI and robotics
|
|
|
| The dataset integrates multi-modal signals:
|
| - SMPL-X human motion sequences
|
| - Object trajectories (4×4 transformation matrices)
|
| - Fine-grained contact annotations
|
| - Structured textual prompts
|
| - Object meshes and SDF representations
|
|

|
|
| ## Key Contributions
|
|
|
| - Role-asymmetric interaction modeling (e.g., giver → receiver)
|
| - Multi-person coordination scenarios
|
| - Multi-object interaction support
|
| - Fine-grained contact supervision
|
| - Aligned text–motion–object representation
