Towards a modular architecture for extended reality systems

For full-fledged social acceptance of eXtended Reality (XR) systems, emphasis should be on design prototypes to allow frictionless, context-aware, and secure interactions with non-specialized users. This necessitates a modular architecture to ensure that the system is versatile and applicable across applications, and is open to the integration of interaction modalities. We discuss our proposal for (and prototypical implementation of) a modular architecture for XR systems that relies on cloud infrastructure resources and edge computing frameworks with shared communication protocols for scalability. The modules are abstracted from both functional and non-functional requirements, including security.
