• Abstract summary: First RHOBIN challenge: reconstruction of human-object interactions in conjunction with the RHOBIN workshop. Our challenge consists of three tracks of 3D reconstruction from monocular RGB images with a focus on dealing with challenging interaction scenarios. This paper describes the settings of our challenge and discusses the winning methods of each track in more detail.

• Abstract: Modeling the interaction between humans and objects has been an emerging research direction in recent years. Capturing human-object interaction is however a very challenging task due to heavy occlusion and complex dynamics, which requires understanding not only 3D human pose, and object pose but also the interaction between them. Reconstruction of 3D humans and objects has been two separate research fields in computer vision for a long time. We hence proposed the first RHOBIN challenge: reconstruction of human-object interactions in conjunction with the RHOBIN workshop. It was aimed at bringing the research communities of human and object reconstruction as well as interaction modeling together to discuss techniques and exchange ideas. Our challenge consists of three tracks of 3D reconstruction from monocular RGB images with a focus on dealing with challenging interaction scenarios. Our challenge attracted more than 100 participants with more than 300 submissions, indicating the broad interest in the research communities. This paper describes the settings of our challenge and discusses the winning methods of each track in more detail. We observe that the human reconstruction task is becoming mature even under heavy occlusion settings while object pose estimation and joint reconstruction remain challenging tasks. With the growing interest in interaction modeling, we hope this report can provide useful insights and foster future research in this direction.

• Generating Human Motion in 3D Scenes from Text Descriptions [60.04976442328767]
  This paper focuses on the task of generating human motions in 3D indoor scenes given text descriptions of the human-scene interactions. We propose a new approach that decomposes the complex problem into two more manageable sub-problems. For language grounding of the target object, we leverage the power of large language models; for motion generation, we design an object-centric scene representation.
