• Abstract: Gaze plays a crucial role in revealing human attention and intention, shedding light on the cognitive processes behind human actions. The integration of gaze guidance with the dynamics of hand-object interactions boosts the accuracy of human motion prediction. However, the lack of datasets that capture the intricate relationship and consistency among gaze, hand, and object movements remains a substantial hurdle. In this paper, we introduce the first Gaze-guided Hand-Object Interaction dataset, GazeHOI, and present a novel task for synthesizing gaze-guided hand-object interactions. Our dataset, GazeHOI, features simultaneous 3D modeling of gaze, hand, and object interactions, comprising 479 sequences with an average duration of 19.1 seconds, 812 sub-sequences, and 33 objects of various sizes. We propose a hierarchical framework centered on a gaze-guided hand-object interaction diffusion model, named GHO-Diffusion. In the pre-diffusion phase, we separate gaze conditions into spatial-temporal features and goal pose conditions at different levels of information granularity. During the diffusion phase, two gaze-conditioned diffusion models are stacked to simplify the complex synthesis of hand-object motions. Here, the object motion diffusion model generates sequences of object motions based on gaze conditions, while the hand motion diffusion model produces hand motions based on the generated object motion. To improve fine-grained goal pose alignment, we introduce a Spherical Gaussian constraint to guide the denoising step. In the subsequent post-diffusion phase, we optimize the generated hand motions using contact consistency. Our extensive experiments highlight the uniqueness of our dataset and the effectiveness of our approach.

  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.

  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 propose an effective representation of grasping state characterizing the spatial interaction between the gripper and the target object. IBS is surprisingly effective as a state representation since it well informs the fine-grained control of each finger with spatial relation against the target object. Experiments show that it generates high-quality dexterous grasp for complex shapes with smooth grasping motions.
