Virtual reality (VR) is widely regarded as technology with huge potential in many application domains beyond entertainment. However, the visualization capabilities of VR headsets hold potential in display-ing business relevant information. In this paper we address utilization of VR technology for visualizing business process models. We developed prototypes of a virtual screen that is tailored to display large models. The evaluation includes detailed usability tests that deepen the understanding of how to use VR for process model visualization.
