DrawMotion: Generating 3D Human Motions by Freehand Drawing

DrawMotion is a new AI system that generates 3D human motions by combining text descriptions with hand-drawn sketches, addressing the problem that people struggle to describe complex movements using words alone. The system uses a diffusion-based framework (a type of AI model that generates outputs by gradually refining random noise) with three key features: automatic conversion of hand-drawn stick figures into motion, a Multi-Condition Module that efficiently combines text and drawing inputs, and training-free guidance that adjusts the output to match user intentions. User studies show this drawing-based approach cuts the time needed to create desired motions by about 46.7% compared to text-only methods.
