Woontack Woo introduces the UVR Lab at KAIST, which researches ubiquitous VR (UVR) and aims to create new spatial computing paradigms. The lab has over 20 PhD students and researchers working on projects involving augmented reality, digital twins, augmented humans, and more. Upcoming projects include creating digital twins with IoT and AI, developing augmented collaboration spaces, and creating augmented tourism and museum experiences using mixed reality. The document outlines several technical challenges remaining in areas like wearable platforms, environment awareness, context-aware augmentation, and social platforms.
