lXR, Metaverse, UVR는 BTS!
§XR은 현실-가상 융합 확장현실 X= A,D,E,M,R,AV,UV,V, etc.
§Metaverse는 아바타로 활동하는 다양한 층위의 확장현실
§UVR은 현실에서 현실-가상융합을 통해 시공간의 한계를 넘어 다양한
형태의 연결, 소통, 협업 등이 가능한 똑똑한 확장현실

lWhat is Ubiquitous VR? [Woo01]
§연결 3D Link with IoE between twin (real & virtual) worlds
§증강 CoI (Context-of-Interest) Augmentation with Data, not just sight
(sound, haptics, smell, taste, etc.) but information
§협업 Bidirectional Interaction/Collaboration with Intelligence for
O2O/H2H Communications
