Addressing Concepts for Mobile Location-Based Information Services

Emerging mobile location-based information services enable people to place digital content into the physical world. Based on three technical components (1) mobile devices, (2) wireless networking and (3) location-sensing the implementation of location-based services can be considered state of the art. In contrast, we observe a lack of conceptual work in terms of user interface issues, like designing indirect (one-to-any) addressing models, handling information overflow and avoiding spam. Every user is able to arbitrarily place information anywhere without structure or restrictions, and is confronted with an information mess in return. The focus of this paper concentrates on a novel addressing concept for mobile location-based information services, which systematically structures both direct and indirect addressing methods and supports the users in finding or filtering the information they are interested in.
