Contact-aware Human Motion Generation from Textual Descriptions

Core Concepts

Generating 3D interactive human motion from textual descriptions with a focus on contact modeling.

Abstract

The paper addresses the challenge of generating 3D human motion from text, emphasizing the importance of considering interactions by physical contacts. It introduces a novel dataset named RICH-CAT and proposes an approach named CATMO for text-driven interactive human motion synthesis. The method integrates VQ-VAE models for encoding motion and body contact sequences, an intertwined GPT for generating motions and contacts, and a pre-trained text encoder for learning textual embeddings. Experimental results demonstrate the superior performance of the proposed approach compared to existing methods in producing stable, contact-aware motion sequences.

Deeper Inquiries

How can the integration of object geometry enhance the adaptability of the model?

Integrating object geometry into the model can significantly enhance its adaptability by providing crucial contextual information for generating realistic interactive human motions. By incorporating object geometry, the model gains a deeper understanding of how human movements interact with their surroundings. This allows for more accurate and context-aware motion synthesis, especially when considering actions that involve physical contact with objects. The inclusion of object geometry enables the model to generate motions that are not only visually natural but also physically plausible in relation to the environment. Additionally, by considering object geometry, the model can better simulate interactions in various scenarios and environments, leading to more versatile and adaptable motion generation capabilities.

What are potential limitations or biases in using automated annotation pipelines for generating interaction descriptions?

While automated annotation pipelines offer efficiency and scalability in generating interaction descriptions, there are potential limitations and biases associated with their use:

Lack of Contextual Understanding: Automated systems may struggle to grasp nuanced contextual details present in textual descriptions, leading to inaccuracies or misinterpretations.
Sensitivity to Ambiguity: Textual descriptions containing ambiguous language or multiple interpretations may result in inconsistent annotations or incorrect labeling.
Overreliance on Predefined Templates: Automated pipelines often rely on predefined templates for description generation, which may limit creativity and flexibility in capturing diverse interactions accurately.
Limited Handling of Complex Interactions: Automated systems may face challenges when dealing with complex interactions that require deep semantic understanding beyond surface-level text analysis.
Biases in Training Data: Biases present in training data used to develop automated annotation models can propagate into generated annotations, potentially introducing skewed or inaccurate descriptions.
