The Third Workshop on Locomotion and Wayfinding in XR, held in conjunction with IEEE VR 2025 in Saint-Malo, France, is dedicated to advancing research and fostering discussions around the critical topics of navigation in extended reality (XR). Navigation is a fundamental form of user interaction in XR, yet it poses numerous challenges in conceptual design, technical implementation, and systematic evaluation. By bringing together researchers and practitioners, this workshop aims to address these challenges and push the boundaries of what is achievable in XR navigation.
