DragMesh Hand-Object Interaction Dataset

This dataset pairs simulation-generated hand-object interaction (HOI) trajectories with the corresponding PartNet-Mobility object assets used to generate them. Only objects with validated HOI trajectories are included.

Dataset layout

  <object_id>/
    hoi_trajectories/

dataset_manifest.jsonl
  • <category> is the PartNet-Mobility object category.
  • <object_id> is the source PartNet-Mobility directory identifier.
  • hoi_trajectories/ contains one trajectory directory per manipulated handle or articulated part.
  • partnet_mobility/ contains the complete matching source object directory.
  • dataset_manifest.jsonl provides one machine-readable record per object.

Trajectory format

Each trajectory.json contains the following fields:

  • phase
  • step
  • virtual_xyz
  • wrist_rpy
  • finger_dofs
  • wrist_pos
  • wrist_rot
  • joint_positions

The trajectories were generated in simulation with a heuristic rule-based pipeline.

Source assets

The object geometry and articulation metadata under partnet_mobility/ are derived from PartNet-Mobility. Please cite the PartNet and PartNet-Mobility projects and follow their applicable terms when using or redistributing these assets.
