The 1st Embodied Spatial Reasoning Workshop at ICCV 2025 explores the integration of spatial understanding in intelligent agents. Focus areas include Embodied AI, which allows agents to perceive, reason, and act in real-world or simulated environments, and Spatial Reasoning, which involves interpreting spatial relations and sensory feedback. The workshop also delves into the development of Embodied World Models for building spatially coherent, semantically grounded internal representations, and Robot Spatial Reasoning, addressing challenges in planning and acting under uncertainty and task constraints. The goal is to advance robust, generalizable spatial reasoning for embodied agents.
