When establishing a visual connection between a virtual reality user and an augmented reality user, it is important to consider whether the augmented reality user faces a surplus of information. Augmented reality, compared to virtual reality, involves two -not one -planes of information: the physical and the virtual. We propose SelectVisAR, a selective visualisation system of virtual environments in augmented reality. Our system enables an augmented reality spectator to perceive a co-located virtual reality user in the context of four distinct visualisation conditions: Interactive, Proximity, Everything, and Dollhouse. We explore an additional two conditions, Context and Spotlight, in a follow-up study. Our design uses a human-centric approach to information filtering, selectively visualising only parts of the virtual environment related to the interactive possibilities of a virtual reality user. The research investigates how selective visualisations can be helpful or trivial for the augmented reality user when observing a virtual reality user.

Responsive architecture envisions the built environment to adapt to the changing needs of its occupants dynamically. Although it is increasingly feasible to move space-defining objects like room dividers by mobile robots, little is known about how or when such spatial adaptations should occur. We therefore measured the experience of 26 occupants while they performed six different activities inside an office breakout room that was being adapted by a robotically moving wall in either a reactive or proactive way. Based on these empirical findings, we propose how autonomous spatial adaptation should primarily aim to balance the spatial, situational and subjective qualities of the resulting sense of place. We also define eight distinct design recommendations that exploit the unique affordances of spatial adaptation. By asserting that future advances in human-building interaction (HBI) should be based on creating appropriate places rather than controlling functional spaces, we foresee how responsive architecture might become as compelling as its static counterpart.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
