Introduction

HOT3D is a dataset for benchmarking egocentric tracking of hands and objects in 3D. The dataset includes 833 minutes of multi-view image streams, which show 19 subjects interacting with 33 diverse rigid objects and are annotated with accurate 3D poses and shapes of hands and objects. HOT3D is recorded with two head-mounted devices from Meta: Project Aria, a research prototype of light-weight AR/AI glasses, and Quest 3, a production VR headset sold in millions of units.

We aim to support research on egocentric hand-object interaction by making HOT3D publicly available and by co-organizing public challenges on the dataset: BOP Challenge 2024, focused on model-based and model-free 2D object detection and 6DoF pose estimation, and Multiview Egocentric Hand Tracking Challenge, focused on hand pose and shape estimation. To enable benchmarking methods for joint hand and object tracking, the two challenges use the same training and test splits. We invite authors of relevant methods to participate in the challenges.

Dataset properties

  • 833 minutes of egocentric, multi-view, synchronized recordings: HOT3D offers 1.5M multi-view frames (3.7M+ images) recorded at 30 FPS with Project Aria and Quest 3. Each Aria frame includes one RGB 1408×1408 and two monochrome 640×480 images. Each Quest 3 frame includes two monochrome 1280×1024 images. Aria recordings also include 3D scene point clouds from SLAM and eye gaze signal.
  • 19 subjects, 4 everyday scenarios: To ensure diversity, we recruited 19 participants with different hand shapes and nationalities. In addition to simple pick-up/observe/put-down actions, recordings show scenarios resembling typical actions in a kitchen, office, and living room. All scenarios were captured in the same lab with scenario-specific furniture and regularly randomized decorative elements and lighting. In each ~2 minute recording, a participant interacts with up to 6 objects.
  • Accurate 3D ground-truth annotations of hands and objects: Hands and objects are annotated with ground-truth 3D poses and models. Models were scanned by in-house 3D scanners and poses obtained by a professional motion-capture system using small optical markers. Hand annotations are provided in the UmeTrack and MANO formats.
  • High-fidelity 3D object models: HOT3D includes high-fidelity 3D models of 33 rigid objects. Each model is captured with high-resolution geometry and PBR materials, using an in-house 3D scanner. The collection includes household and office objects of diverse appearance, size, and affordances.
  • Sequences for object onboarding: To support research on model-free 3D object tracking and 3D object reconstruction, HOT3D offers two types of reference sequences which show all possible views at each object: (1) sequences showing a static object on a desk, when the object is standing upright and upside-down, and (2) sequences showing an object manipulated by hands.

HOT3D-Clips

HOT3D-Clips is a set of curated sub-sequences of the HOT3D dataset, provided to enable straightforward comparison of various tracking and pose estimation methods. The clips are used in the BOP Challenge 2024 and Multiview Egocentric Hand Tracking Challenge. Each clip has 150 frames (5 seconds) with ground-truth annotations available for all modeled objects and hands and passing our visual inspection. There are 3832 clips in total, with 1983 extracted from Aria recordings and 1849 extracted from Quest3 recordings. Documentation of HOT3D-Clips and Python utilities for working with the clips are in the HOT3D Toolkit.
