Achieving compatibility of VR systems with MRI scanners is challenging and for applications such as fMRI, it is highly desirable to avoid local distortions of the static magnetic field. We have developed a non-intrusive MR compatible VR system which avoids disturbing the magnetic environment and uses eye tracking as the main interface. Our system demonstrates a capability to bring the VR world into MRI systems, including dynamic interaction with VR content based on gaze, with performance that it is competitive to the current leading commercial gaming eye tracker.
