The system takes person and product inputs and synthesizes interaction videos that show realistic handling, rotation, contact, and presentation behavior. This is important because human-object interaction is one of the hardest parts of generative video: hands must meet objects, objects must remain stable, and movement must obey physical constraints. CoInteract focuses on spatially structured co-generation to keep the person and object synchronized.
CoInteract is valuable for ecommerce, product marketing, digital human demos, and research into physically grounded video generation. Its public code and Hugging Face links make it practical for technical users to evaluate how well structured generation can handle real human-product interaction scenarios.
