In this paper, we propose a Trans-Space convergence system that exploits realistic 3D remote collaboration with spatial co-presence by using augmented reality technology. To experience it, we define two major enabling technologies: 1) Context-of-Interest (CoI) based Trans-Space registration and selective augmentation and 2) augmented object interaction for realistic collaboration. Through these technologies, a user wearing augmented reality (AR) glasses can naturally experience remote collaboration with spatial co-presence while moving in space. We implemented a prototype of the Trans-Space for a preliminary test experiencing spatial co-presence in an indoor environment. With an assumption that a common physical CoI is in each space, a distant mirror space can be conveniently linked with real user’s mirror space and they are merged together as a Trans-Space. Through the proposed convergence system, a human’s co-presence experience can be enlarged by selectively context sharing and effectively spatial interaction between remote mirror spaces. We expect this is applicable to AR-based time/space transcended smart applications, such as the next generation of experimental education, training, medical surgery, and entertainment.
