FlowHOI Demo Data

Demo inputs for FlowHOI, containing two GRAB sequences and one HOT3D sequence for inference and visualization.

Paper	arXiv 2602.13444
Project page	https://huajian-zeng.github.io/projects/flowhoi/
Code	https://github.com/huajian-zeng/flowhoi
Checkpoints and installation	huajian-zeng/flowhoi

Files

Directory	Description
dataset/GRAB_HANDS/	Mug-passing and toy-train demos, with captions, normalization statistics, and precomputed object/text features
dataset/HOT3D_HANDS/	Cellphone demo, with captions, object/text features, occupancy, and scene inputs
dataset/ shared files	Sequence lookup tables and loader compatibility files

This package contains only the demo examples, not the full GRAB/HOT3D splits or EgoDex training data.

Usage

Follow the model repository's installation instructions, then download from the FlowHOI code repository root:

hf download --repo-type dataset huajian-zeng/flowhoi-data \
  --include 'dataset/**' --local-dir .

The code repository's demo.sh uses these files with the released checkpoints. MANO models, GRAB meshes and subject templates, and HOT3D object meshes are obtained separately as described in the installation guide.

The original data providers’ terms apply; see the code repository for data sources and access requirements.
