TeleGhost: Asymmetric Telepresence System Using AR and VR Avatars in a Shared Real Space

This study proposes a simplified telepresence system based on extended reality for increasing the number of remote-able tasks. The system provides an immersive virtual environment that duplicates remote real spaces to enable communication among system users in different geographic locations through their digital avatars. The motion of the avatars corresponds with that of the mobile devices manipulated by the system users, and the avatars' position and orientation in the real space represent the viewpoint and viewing angle of the users. The three experiments showed that the proposed system creates a high-fidelity immersive environment in a short period of time and positively supports users' remote collaboration in the virtualized real space. The system successfully demonstrated its potential to contribute to the expansion of remotely enabled operations.
