We present two novel redirection techniques to enable real walking in large virtual environments (VEs) using only \u201croom-scale\u201d tracked spaces. The techniques, called Bookshelf and Bird, provide narrative-consistent redirection to keep the user inside the physical space, and require the user to walk to explore the VE. The underlying concept, called cell-based redirection, is to divide the virtual world into discrete cells that have the same size as the physical tracking space. The techniques then can redirect the users without altering the relationship between the user, the physical space, and the virtual cell. In this way, users can always access the entire cell using real walking.<\/p>\n\n\n\n

Current work on the cell-based redirection project involves testing these techniques against current redirection and relocation techniques. We are comparing the ability of the Bookshelf and Bird to help a user maintain their spatial orientation within a VE against that of the Two-to-One Turn redirection technique and the Teleportation relocation techniques. We hypothesize that a user’s ability to recall locations of landmarks and navigate via the shortest path to a previously visited location will be improved using these novel cell-based redirection techniques.<\/p>\n\n\n\n
