• Abstract: Real-time tracking of 3D hand pose in world space is a challenging problem and plays an important role in VR interaction. Existing work in this space are limited to either producing root-relative (versus world space) 3D pose or rely on multiple stages such as generating heatmaps and kinematic optimization to obtain 3D pose. Moreover, the typical VR scenario, which involves multi-view tracking from wide \ac{fov} cameras is seldom addressed by these methods. In this paper, we present a unified end-to-end differentiable framework for multi-view, multi-frame hand tracking that directly predicts 3D hand pose in world space. We demonstrate the benefits of end-to-end differentiabilty by extending our framework with downstream tasks such as jitter reduction and pinch prediction. To demonstrate the efficacy of our model, we further present a new large-scale egocentric hand pose dataset that consists of both real and synthetic data. Experiments show that our system trained on this dataset handles various challenging interactive motions, and has been successfully applied to real-time VR applications.

  We propose a two-stage framework that can obtain accurate and smooth full-body motions with three tracking signals of head and hands only. Our framework explicitly models the joint-level features in the first stage and utilizes them astemporal tokens for alternating spatial and temporal transformer blocks to capture joint-level correlations in the second stage. With extensive experiments on the AMASS motion dataset and real-captured data, we show our proposed method can achieve more accurate and smooth motion compared to existing approaches.

  Hand trajectory forecasting is crucial for enabling a prompt understanding of human intentions when interacting with AR/VR systems.

We set up an egocentric 3D hand trajectory forecasting task that aims to predict hand trajectories in a 3D space from early observed RGB videos in a first-person view.
