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

Dataset Structure

The dataset is distributed primarily as a compressed archive:

CoRoleHOI/ ├── data.zip ├── README.md ├── croissant.json

Data Modalities

Each interaction sequence includes:

Modality	Description
Human Motion	SMPL-X parameters
Object Motion	4×4 transformation matrices
Contact Labels	Binary / semantic contact
Text	Natural language interaction description
Metadata	Human & object attributes

Text Annotations

The dataset provides structured language supervision:

augmented_prompts.json
Multiple paraphrases per interaction
prompt_dict.json
Prompt ID to canonical text mapping
split_prompts.json
Train / validation / test splits

Example Interaction

Person A passes the printer to Person B.
