Immersive design fiction is a novel approach that embeds speculative interactions within a rich virtual reality (VR) storyworld. Immersive design fictions use VR to translate new design opportunities into story-driven, embodied experiences by positioning the participant as a character in a narrative world. This research develops a case study of an immersive design fiction that depicts a fictionalized reimagining of an industry partner’s work practices. This VR experience explores speculative interfaces for creative work and collaboration in the context of a fictional workplace environment. By placing design fictions within rich immersive contexts such as room-scale VR, researchers and practitioners can go beyond prototyping imagined interfaces to also speculate about the interaction rituals and surrounding social context within an experiential storyworld. This approach makes methodological and theoretical contributions to design fiction research by demonstrating a toolkit for exploring and reflecting upon the intersections between speculation, embodiment, and narrative context.
