Asymmetric games rely on players taking on different gameplay roles, often with associated different views of the game world and different input modalities. This asymmetry can lead to difficulties in establishing common referents as players collaborate. To explore communication and group awareness in asymmetric games, we present a novel asymmetric game, combining a tablet presenting a 2D top-down view and a virtual reality headset providing an immersive 3D view of the gameworld. We demonstrate how communication can be afforded between the two types of views via interaction techniques supporting deixis, shared reference, and awareness. These techniques are bi-directional, enabling an equitable collaboration. A pilot study has shown that players adapt well to the system's two roles, and find the collaborative interaction techniques to be effective.
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.
