A Hybrid Content Delivery Approach for a Mixed Reality Web Service Platform

This paper presents the development of a Mixed Reality Web service platform (MRS-WS). The platform provides a general RESTful interface for building rich mixed reality mash-ups and 3rd party solutions for open innovation. The platform serves geo-spatially oriented content, advanced geo-data like 3D building models, street-view panoramas and terrain mesh data, and a generic service plug-in model for integrating 3rd-party services and social connections in a secure and scalable manner. Apart from the RESTful approach, this paper presents another case scenario that supports pushing data to many service consumers via a publish/subscribe (pub/sub) mechanism in favor of scalability and expressiveness. Together with the mobile clients, it supports automatic information discovery of "what matters to the user", e.g. based on the built-in mobile sensors and simple user contexts. The paper describes the design and experiments in the industrial scenario.
