Mixed reality web service platform

This paper presents a RESTful Web service platform for applications for both Web browsers and mobile clients. Having a common service backend makes creating applications fast, simple, and open to third parties. The paper presents two mixed reality applications that have been built on the platform. It summarizes requirements for a mixed reality platform and defines a mixed reality domain model that the platform and applications share. In addition, it describes how the clients can use the REST interface to perform operations on user-generated content, as well as access real-life commercial geo-content such as street-view panoramas and building models.

Image space: capturing, sharing and contextualizing personal pictures in a simple and playful way

The increasing use of digital cameras and camera phones has changed peoples behavior regarding the amount of photos that they make. As a result, growing collections of photos are more and more difficult to understand, search and navigate. Helping users make sense of these collections and create an understanding of the world that they depict has become a challenging task. In this paper, we present the design, implementation and evaluation of the Image Space service, which enables users to capture, browse and contextualize their digital photographs with the aid of a community of other users in a simple and playful way. We report evaluations which indicate that the service was easy and to a lesser degree playful to use.

A solution for navigating user-generated content

We have implemented a prototype solution for discovering shared digital media via a novel user interface, presenting the spatial relationships of the content.

An extensible mirror world from user-generated content

In this paper we describe a system for creating a navigable mirror world, utilizing community photographs of real life environments. We present the essential architecture and a prototype solution for not only geotagging, but also spatially structuring content. Mash-up interfaces are available towards 3rd parties, for linking and georeferencing their content.
