2nd Workshop on Multimodal Spatial Intelligence
June 3, 2026 · 8:10 AM – 12:30 PM
Room 601
About the Workshop
Our multi-modal spatial intelligence (MUSI) workshop addresses how multimodal large language models (MLLMs) understand, reason about, and interact with spatial information from the physical world. The multimodal nature of spatial intelligence—requiring integration of images, videos, and 3D data—necessitates bringing together researchers from diverse domains: computer vision, robotics, graphics, and NLP. While recent MLLMs show promising visual-spatial capabilities, fundamental questions remain about spatial relationships, 3D environment modeling, and real-world spatial reasoning. This workshop explores how MLLMs learn spatial representations across modalities, advance world modeling and embodied AI, and address ethical considerations. We aim to establish benchmarks and foster cross-disciplinary collaboration to advance spatial reasoning in multimodal AI.
