• Authors: Rashmi Bakshi, Jane Courtney, Damon Berry, Graham Gavin
• Abstract summary: The process of hand washing, according to the WHO, is divided into stages with clearly defined two handed dynamic gestures. In this paper, videos of hand washing experts are segmented and analyzed with the goal of extracting their corresponding features. A 3D gesture tracker, the Leap Motion Controller (LEAP), was used to track and detect the hand features associated with these stages.

• Abstract: The process of hand washing, according to the WHO, is divided into stages with clearly defined two handed dynamic gestures. In this paper, videos of hand washing experts are segmented and analyzed with the goal of extracting their corresponding features. These features can be further processed in software to classify particular hand movements, determine whether the stages have been successfully completed by the user and also assess the quality of washing. Having identified the important features, a 3D gesture tracker, the Leap Motion Controller (LEAP), was used to track and detect the hand features associated with these stages. With the help of sequential programming and threshold values, the hand features were combined together to detect the initiation and completion of a sample WHO Stage 2 (Rub hands Palm to Palm). The LEAP provides accurate raw positional data for tracking single hand gestures and two hands in separation but suffers from occlusion when hands are in contact. Other than hand hygiene the approaches shown here can be applied in other biomedical applications requiring close hand gesture analysis.

  BimArt is a novel generative approach for synthesizing 3D bimanual hand interactions with articulated objects. We first generate distance-based contact maps conditioned on the object trajectory with an articulation-aware feature representation. The learned contact prior is then used to guide our hand motion generator, producing diverse and realistic bimanual motions for object movement and articulation.

  ManiDext is a unified hierarchical diffusion-based framework for generating hand manipulation and grasp poses. Our key insight is that accurately modeling the contact correspondences between objects and hands during interactions is crucial. Our framework first generates contact maps and correspondence embeddings on the object's surface. Based on these fine-grained correspondences, we introduce a novel approach that integrates the iterative refinement process into the diffusion process.

  Estimating 3D interacting hand pose from a single RGB image is essential for understanding human actions. We propose to decompose the challenging interacting hand pose estimation task and estimate the pose of each hand separately. Experiments show that the proposed method significantly outperforms previous state-of-the-art interacting hand pose estimation approaches.
