This paper, produced by the DRCF Horizon Scanning and Emerging Technologies project team, is the product of a research and foresight activity cycle to consider the future of immersive technologies, to better understand how immersive environments might evolve and the key uncertainties that could drive changes to them. Our process included conducting desk-based research and a series of interviews and workshops with internal and external experts. This foresight paper summarises insight from that process and then sets out the potential regulatory implications that may arise depending on how these environments develop in the future.
