Embedding virtual environments into the physical world: memorability and co-presence in the context of pervasive location-based games

Abstract

Realistic 3D virtual environments, such as existing city models, have the potential to be used in pervasive games as a passageway between physical and virtual. Smooth attention displacement and transitions between these two realities are largely unexplored in the context of pervasive gameplay. We conducted two field trials using a pervasive live action role playing game to study the effect moving between the virtual and the physical has on co-presence and memorability. Although differences in co-presence during gameplay were small, they highlight the subtleties in the social structuring of pervasive gameplay. Spatial similarity between the physical and virtual environments made the 3D virtual environments more memorable. We identify two important issues to consider in embedding virtual environments into pervasive games: structuring of social interactions and the spatial realism of the VEs.
