Paper Maps as an Entry Point for Tourists to Explore Wikipedia content

In this demonstration we present a mobile tourist guide. It makes geographically referenced Wikipedia content accessible via camera phones, which are used as magic lenses for paper maps. Visual and auditory output is controlled by moving and rotating the phone over a paper map. Many people still use paper maps, because they provide high-resolution, large-scale information with zero power consumption. A drawback of paper maps is that they neither provide personalized nor dynamic information. In our approach we augment paper maps with geospatial content using camera phones as see-through tools. The dynamic content is retrieved from Web 2.0 applications like Wikipedia, which aggregate contributions from many users.
