Semantic Exploration of Distributed AR Services.

In this paper, we present a new approach to building large-scale ubiquitous augmented reality (AR) applications. Instead of fixed AR content, presented on specific places or objects, we propose the concept of a semantic network of distributed AR services contributed by different providers. These services have different roles and offer different content and functionality, but the synergy offered by such a diverse network of services opens new fields of application for AR systems. The services in our approach are modeled using well-established standards from the domain of business process modeling, but they are additionally annotated using semantic descriptions of the role and properties of particular services and their relationships, allowing meaningful selection of dynamic exploration paths by users with different interests, constraints and privileges. An indispensable element of such heterogeneous AR systems is proper consideration of security and privacy issues, which are also covered in this work.
