ABSTRACT
More than a fixed category, “XR” can refer to the continuum between augmented (AR) and virtual reality (VR), and the hybrid genres of mixed or extended reality (MR). Crossing asks how the intersection of realities is not a specific moment or a a clear point of transition. Rather, it exposes a continued interference, resulting of an intra-active relating between co-constitutive entities or “realities.” Thinking with crossing, we can explore the processes and experiences of this emergence this relating of relata, rather than pinpointing borders between the one and the other. This chapter examines how this performative and relational perspective allows to become specific about the intricacies of being, connecting, and acting by means of urban environmental, immersive, and mobile technologies.
