“…In this paper, we address these aspects by proposing a tangible Mixed Reality-based distributed virtual environment (DVE) -MRDVE -for distributed concurrent collaboration, which provides a platform which allows groups of people to share the same work and communications space over a network. There have been several noted research efforts that investigated the applications of distributed Mixed and Augmented Reality technologies for collaborative interior design applications (Ahlers et al, 1995), videoconferencing systems (Barakonyi et al, 2004), tutoring sessions in teaching multi-variate calculus (Orozco et al, 2006). Other examples include the collaborative augmented reality system Studierstube (Schmalstieg, 2002), SharedSpace (Billinghurst and Kato, 1999), and mediaBlocks (Ullmer et al, 1998).…”
