The Cyberneum is a state-of-the-art Virtual Reality (VR) research facility of the Department of Professor Bülthoff. It is equipped with several sophisticated VR systems that are providing unique opportunities to study human perception and human-machine interactions. The main areas of research in the Cyberneum relate to self-motion perception, spatial cognition, multiuser interactions, multisensory integration, and cybernetics as it relates to perception and action. In each of these areas it is important to both understanding the processes underlying human sensory/motor perception under the most natural conditions, while at the same time maintaining precise experimental control. Rapid developments in multimodal VR technologies are now providing the tools necessary to create realistic, highly controlled experimental conditions.
