Navigating Virtual Reality by Thought: What Is It Like? Doron Friedman *Department of Computer Science, University College London, London, UK Robert Leeb Laboratory of Brain-Computer Interface, Graz University of Technology, Graz, Austria Christoph Guger g.tec—Guger Technologies OEG, Graz, Austria Anthony Steed Department of Computer Science, University College London, London, UK Gert Pfurtscheller Laboratory of Brain-Computer Interface, Graz University of Technology, Graz, Austria Mel SlaterDepartment of Computer Science, University College London, London, UK and ICREA Universitat Politècnica de Catalunya, Spain Abstract We have set up a brain-computer interface (BCI) to be used as an input device to a highly immersive virtual reality CAVE-like system. We have carried out two navigation experiments: three subjects were required to rotate in a virtual bar room by imagining left or right hand movement, and to walk along a single axis in a virtual street by imagining foot or hand movement. In this paper we focus on the subjective experience of navigating virtual reality “by thought,” and on the interrelations between BCI and presence.
