X Reality Networked Performance: Message Based Distributed Systems for Controlling and Presenting Multiple Realities

X reality networked performances connect physical, fictional and computer generated realities in a new world of performance, one that is without geographical bounds and that can include many physical locations—with their own performers and audience members— within a single event. They explore a unique medium while drawing on historical and contemporary performing arts practices that normally occur within the confines of a single physical location.

Such performances present a special set of requirements on the system that supports them. They need to access and integrate all the systems that are typically found in the physical place of the performance (such as theatre lighting) with those that are unique to the medium, such as network technologies and environments for the delivery of computer generated realities. Yet, no suitable systems or frameworks have been developed to support them. Technologies are available (such as LoLA and UltraGrid) that support individual aspects—like audio/video streaming—but which do not address the wider requirements of controlling and synchronising, of integrating all these technologies into a system of systems for X reality networked performance.

Therefore, this research investigates the creation of a systems framework whereby existing hardware and software components can be continuously integrated with bespoke components to provide a platform for the delivery of X reality networked performances. The methodological approach to this investigation is through the lens of the author’s previous experience in other fields of complex systems integration, including, approaches employed in the design and integration of avionics systems.

Specifically, it tests if a systems integration approach to providing a technical platform for X reality networked performances, one that employs strongly‐defined interfaces and communication protocols, and that is based on open and industry standards, delivers an elegant platform that can be characterised as: deterministic, reliable, extendable, scalable, reconfigurable, testable and cost effective.

The platform for X reality networked performance has been developed iteratively—using the results of a framework investigation—and tested in four different performance projects over a period of 24‐months, in ten different venues, across five countries. The research concludes that the enabling framework is well suited to the delivery of X reality networked performances. Also, that the approaches employed could equally be applied to the needs of other arts practitioners who rely on complex technical systems for the creation and delivery of their work.
