• Abstract: We introduce a multi-stage framework that uses mean curvature on a hand surface and focuses on learning interaction between hand and object by analyzing hand grasp type for hand action recognition in egocentric videos. The proposed method does not require 3D information of objects including 6D object poses which are difficult to annotate for learning an object's behavior while it interacts with hands. Instead, the framework synthesizes the mean curvature of the hand mesh model to encode the hand surface geometry in 3D space. Additionally, our method learns the hand grasp type which is highly correlated with the hand action. From our experiment, we notice that using hand grasp type and mean curvature of hand increases the performance of the hand action recognition.

  We propose DiffH2O, a novel method to synthesize realistic, one or two-handed object interactions. We decompose the task into a grasping stage and a text-based interaction stage. In the grasping stage, the model only generates hand motions, whereas in the interaction phase both hand and object poses are synthesized.

  We present AffordPose, a large-scale dataset of hand-object interactions with affordance-driven hand pose.

The comprehensive data analysis shows the common characteristics and diversity of hand-object interactions per affordance.

  Hands are dexterous and highly versatile manipulators that are central to how humans interact with objects and their environment. modeling realistic hand-object interactions is critical for applications in computer graphics, computer vision, and mixed reality. GRIP is a learning-based method that takes as input the 3D motion of the body and the object, and synthesizes realistic motion for both hands before, during, and after object interaction.

  Estimating 3D interacting hand pose from a single RGB image is essential for understanding human actions.

  Self-similarity, and the resulting ambiguities in assigning pixel observations to the respective hands, is a major cause of the final 3D pose error.

We experimentally show that the proposed approach achieves new state-of-the-art performance on the InterHand2.6M dataset.

  We build upon the insight that body motion and hand gestures are strongly correlated in non-verbal communication settings.

Our hand prediction model produces convincing 3D hand gestures given only the 3D motion of the speaker's arms as input.
