Scalable Techniques for Collaborative Outdoor Augmented Reality

چکیده
Research on mobile augmented reality (AR) so far concentrated on building and deploying prototypes and investigating technical and user interface aspects. To create plausible application scenarios other concerns also need to be addressed. In particular, the size of the physical world made accessible by mobile AR raises new challenges in terms of scalability: the system will among others need a very large 3D world model, display this model efficiently without visual clutter or graphics overload, should operate in networked mode with arbitrary collaborators, provide tracking anywhere etc. In this paper we address some of these scalability issues, namely data management for very large geographic 3D models, and efficient techniques for collaborative outdoor user interfaces. As an application scenario, we use a tourist group guide application operating in the city of Vienna.

متن کاملCollaborative Augmented Reality for Outdoor Navigation and Information browsing
Augmented reality (AR) can provide an excellent user interface for visualization in a mobile computing application. The user’s view is augmented with location based information at the correct spatial location, thus providing an intuitive way of presenting such information. In this work we demonstrate the use of AR for collaborative navigation and information browsing tasks in an urban environme...
