Abstract: This study proposed a Mixed Reality (MR) mutual space generation method that aligns the Virtual Reality (VR) clients’ spaces around the Augmented Reality (AR) host space’s reference object and adjusts the virtual space’s scale with translation-based Redirected Walking (RDW). Although there were methods to create shared spaces by finding optimal transform or each space to maximize the semantically aligned area, there was a lack of research on utilizing the effect of rescaling a VR client’s space with the RDW technique. We leveraged Relative Translation Gains (RTGs), a length-based RDW technique, to maximize the semantic information matching ratio between the AR host space and the VR clients’ spaces by rescaling the client’s virtual space within a suitable threshold range according to the spatial configuration. Our pilot study results show that the semantic information matching rate between the AR and the VR space increased compared to the existing one-to-one scale matching method while maintaining a unified coordinate system. Our findings can be used to create a more expansive mutual space for asymmetric remote collaboration even if remote spaces increase and challenging to secure a sufficient shared area.

Abstract: This paper evaluates factors of social presence during a dynamic remote collaboration task in a technologically asymmetric Mixed Reality (MR) setting for two spatial layouts. While active movement during MR remote collaboration is afforded by how the shared 3D space is mediated and configured, studies investigating the impact of these conditions on user experience have been scarce. In a between-group study (n=48), a host user in Augmented Reality (AR) and a remote user in Virtual Reality (VR), both wearing Head Mounted Displays (HMDs), simultaneously moved around the shared space to find and assemble parts of a Mars exploration rover together, one group in a Peripheral layout and the other in a Scattered layout with disparate levels of spatial affordance. Results show that while VR facilitates higher co-presence and spatial presence than AR through HMDs, the Peripheral layout enables users to pay more attention to one another than the Scattered. We analyze the results and derive implications aimed at bridging the AR-VR gap in social presence for dynamic MR remote collaboration through the adaptive placement of virtual content in shared spaces.
