Towards Immersive Mixed Reality Street Play: Understanding Collocated Bodily Play with See-through Head-Mounted Displays in Public Spaces (2505.12516v1)

Abstract: We're witnessing an upcoming paradigm shift as Mixed Reality (MR) See-through Head-Mounted Displays (HMDs) become ubiquitous, with use shifting from controlled, private settings to spontaneous, public ones. While location-based pervasive mobile games like Pok\'emon GO have seen success, the embodied interaction of MR HMDs is moving us from phone-based screen-touching gameplay to MR HMD-enabled collocated bodily play. Major tech companies are continuously releasing visionary videos where urban streets transform into vast mixed reality playgrounds-imagine Harry Potter-style wizard duels on city streets. However, few researchers have conducted real-world, in-the-wild studies of such Immersive Mixed Reality Street Play (IMRSP) in public spaces in anticipation of a near future with prevalent MR HMDs. Through empirical studies on a series of research-through-design game probes called Multiplayer Omnipresent Fighting Arena (MOFA), we gain initial understanding of this under-explored area by identifying the social implications, challenges, and opportunities of this new paradigm.
