Abstract

Abstract To enable generalized human motion generation, this paper proposes a unified generation framework, UniMotion, which supports multimodal inputs including text, image and audio. The method uses a unified prompt encoder to map different inputs into a shared cross-modal semantic space. It adopts a two-stage motion decoder to gradually generate fine-grained skeleton sequences. A multimodal alignment loss function is introduced to strengthen consistency modeling across different prompts. In semantic generalization evaluation and prompt consistency tests, UniMotion outperforms baseline methods by 7.3% and 8.9%, respectively. In random multimodal prompt switching tests, it maintains 92.4% motion stability and logical consistency, demonstrating good practicality and scalability. This study expands the application scope of multimodal generative models in human motion modeling.
