CARS: Collaborative Augmented Reality for Socialization.

As Augmented Reality (AR) ties closely to the physical world, its users looking at overlapped scenes are likely to be in the vicinity of each other, which naturally enables the collaboration and interaction among them. In this paper, we propose CARS (Collaborative Augmented Reality for Socialization), a framework that leverages the social nature of human beings to improve the user-perceived Quality of Experience (QoE) for AR, especially the end-to-end latency. CARS takes advantage of the unique feature of AR to support intelligent sharing of information between nearby users when it is feasible. It brings various benefits at the user, application and system levels, e.g., reduction of end-to-end latency and reuse of networking and computation resources. We demonstrate the efficacy of CARS through a preliminary evaluation based on a prototype implementation.
