Two user tests
• 1. Test in November 2010– Is the interface useful (for a general public)?
Accessibility, Learnability, Efficiency, Correctness– Does it provide a new scientific approach / method
Appropriateness, Quality, Explorative methods– Tests guided by facilitator
• 2. Test in March 2011– Complex tasks/puzzles– Had to be solved alone– Tutorial video as a guided tour
Technological Framework (open source)
• OpenLayers• Simile Timeline/Timeplot• GeoNames (Geoparser...)• Explorer Canvas (Google)• GeoServer (OpenStreetmap, Google Maps)• Google Web Toolkit (GWT)• KML (XML)
