The field of virtual reality (VR) environments and neurofeedback applications for functional magnetic resonance imaging is huge. Some groups applied VR for fMRI-based neurofeedback paradigms and human brain interfaces. Our aim is the development and implementation of a VR paradigm library with some common VR scenes and a well-structured modular virtual environment system that allows the import of these virtual reality measurement paradigms just by few mouse clicks. For testing, we used our system as a real time human brain interface where subjects navigated through a three-dimensional maze using brain activations of different cortical areas.
