Abstract

This paper introduces TOUCH, a novel framework for the text-guided, controllable generation of free-form hand-object interactions. The method aims to synthesize realistic and diverse hand poses interacting with objects based on descriptive text inputs. It addresses the challenge of creating intuitive and flexible control over complex 3D manipulative actions, with potential applications in virtual reality, animation, and robotics.

1. Introduction

Hand-object interactions are fundamental for understanding and simulating human activities in 3D environments, yet their synthesis remains challenging due to high dimensionality and diverse contact points. Existing methods often lack intuitive control or struggle with generating free-form interactions. This work presents TOUCH to enable text-guided, controllable generation of such complex interactions. No specific models are described in the article title alone.

2. Related Work

Relevant literature likely includes research on 3D hand pose estimation, object pose estimation, and learning hand-object interaction priors from data. Works on generative models for 3D content, particularly those leveraging text prompts, would also be pertinent. Previous approaches to controllable 3D asset generation or physics-based simulations of manipulation are anticipated.

3. Methodology

The methodology likely involves a deep learning architecture that translates textual descriptions into parameters governing hand and object configurations. This could include a text encoder, a 3D generative model (e.g., a diffusion model or GAN), and possibly an interaction module ensuring physical plausibility. The process would focus on enabling fine-grained control over various interaction attributes through text.

4. Experimental Results

Experimental results would typically demonstrate the framework's ability to generate a variety of hand-object interactions with fidelity and diversity, guided by diverse text prompts. Qualitative examples would showcase generated 3D models and their interactions, while quantitative metrics might evaluate realism, adherence to text, and success rates. No specific experimental results or tables can be generated from the article title alone.

5. Discussion

The discussion would likely interpret the effectiveness of text guidance in simplifying the generation of complex hand-object interactions and highlight the benefits of free-form control. Potential limitations, such as computational overhead or generalization to highly novel objects, would be considered. Future work might explore real-time applications, multi-person interactions, or integration with physical simulation engines.
