Universal XR Framework Architecture Based on Open-Source XR Tools

Virtual and Augmented Reality (VR/AR) experiences are being developed by a large global community using diverse game engines and frameworks. Each research laboratory or private company is developing its own solutions, and there is a common tendency to re-implementing basic Extended Reality (XR) tools that have already been developed by other people. The overarching issue is the lack of an open-source framework that would combine a sufficient set of modules to provide common XR functionality without additional development effort. In addition, the modules must have clear semantic distinctions and be easily discoverable for both experienced and novice users. This work aims to propose the architecture of such framework based on the Unity game engine and distributed as open-source software. The envisioned solution can facilitate better collaboration and knowledge exchange between XR researchers and industry professionals by providing a common standard for sharing experiences and toolkits developed in this domain. The description is supplemented by potential use cases of the XR framework in educational and industrial scenarios.
