The Data Visualization Space (Davis) has been established as a central virtual reality (VR) visualization infrastructure for teaching and science communication at TU Wien. Located in the university library, it provides a single-wall active stereo CAVE environment with optical tracking and is intended to serve a variety of use-cases from all faculties spanning across the STEM disciplines. However, a number of important applications only support VR via consumer-level head-mounted displays (HMD) and are thus unable to be used with the professional-level VR hardware provided. We describe our approach to overcome this limitation by using the open-source Monado OpenXR framework to provide a driver that registers our CAVE environment as a HMD, enabling it to accommodate popular but otherwise incompatible applications.
