The Virtual Reality User Interface (VRUI) is an open-source platform for collaborative and immersive data exploration used at several research institutions. VRUI was uniquely designed from the beginning to be hardware-agnostic, and in recent years has been adapted to run on new generations of consumer VR headsets. This grant supports an ambitious plan to rebuild and better document the project’s configuration and interaction systems, substantially lowering the technical expertise required to run VRUI on a new dataset. To diversify the project’s supporters, this grant will support software contributions from and applications by labs at NIST and Villanova. While the data visualization aspects of VRUI are compelling in their own right, its ability to support multi-user, remote, real-time collaboration is perhaps even more exciting. Nearly all social VR platforms on the market are centrally hosted, requiring one to connect to servers run by Meta or other large companies to interact with others. At a time of potential consolidation of social VR into a small number of platforms, VRUI offers an alternative vision of locally managed social infrastructure in science (and beyond).
