The CityView system helps tourists discover the cultural landmarks of the historic city of Luebeck in Northern Germany. Unlike existing guide systems, CityView automatically generates streaming context-aware tours based on shared content from popular media Web-sites. Using the CityView mobile client, Luebeck visitors can discover their current location and indicate their media filtering preferences by selecting a content category and tour. As visitors move throughout the city, the mobile client automatically identifies their physical location on a dynamic map along with the location of nearby media elements. Shared media content appears on the dynamic map located within the visitor’s mobile device. Shared media can include video, audio and image content. As visitors come near shared content the mobile client displays relevant media elements in the visitor’s playlist. Visitors can then stream discovered media content and discover new media elements by changing location or updating their “area of interest” which appears as a red halo around the user’s icon. Contextualized streaming media of Luebeck tourist help visitors decide what they would like to visit next.
One of the main activities of Luebeck tourists is taking pictures or videos using devices such as mobile phones or Micro PCs. After a day in the city, tourists often upload and share their collected media content using popular media sharing Web-sites. In CityView, we have developed a software architecture which allows visitors to contextualize their shared content and allow CityView mobile clients to discover and play it. Visitors contextualize media using the CityView Media Contextualizer Web application, which aggregates the visitors’ shared media content and provides a unified interface for adding supplemental context information. Context information can include a title, description, validity dates, location and a tour filter. To help contextualize media, the physical location of each video can be introduced by using a clickable map interface. Published context information is stored within the CityView context server where it is made available to CityView mobile clients. New visitors to Luebeck will be automatically provided the new shared content – meaning that there is always something new to discover.
