3D, virtual, augmented, extended, mixed reality, and extended content forms: The technology and the challenges

3D representations are a new form of information that when coupled with new technology tools, like VR, AR, MR, 3D scanning/printing, and more, offer new support and opportunities for research and pedagogy, often with dramatic leaps in capabilities and results. When combined with a pandemic, the results can be even more dramatic and valued in a variety of collaborative and higher education applications. However, as with any new technology and tools, there also can be sizable challenges that result and will need to be addressed. These include accessibility, 3D object creation, hardware capabilities, storage, and organizing tools. All represent areas where the community of users and their standards organizations, like NISO, need to move aggressively to develop best practices, guidelines, and standards to ensure these new forms of data and technology tools are widely-accessible. This paper provides a high-level overview to introduce people to the new information form, associated technologies, and their challenges.
