Urbane Ebenen, winter 2010

This course was about the invisible layers of data in an urban context. The aim of the final project was to create a working prototype for a multitouch table or a wall display to show these layers in interactive geo visualizations.

A multitouch application to explore Berlin’s concert landscape. Users can select neighborhoods, music genres, and time ranges to filter and compare various venues.

One interesting finding was that much more concerts are happening in the Eastern parts of Berlin. This fits the expectation, as former East Berlin districts attract many venues due to cheaper real estate prices.

Another finding was slightly unexpected: In summer time there are fewer concerts happening. Among other reasons, this might be due to more festivals going on outside of Berlin.

A multi-touch map to explore and discover patterns of how people in the world are feeling at the moment.

Emography visualizes the aggregated mood of cities as donut charts, to enable comparing various places with each other. The mood is based on the words and phrases of geo-positioned tweets harvested from Twitter. It collects the contents of tweets in real-time, and extracts and calculates the occurrence of six basic feelings.

Users can tap on the map, where their cursor snaps to the nearest city when it’s in proximity. The appearing donut chart contains a zoom view of the place.

Berlin at Lunch is an interactive restaurant visualization and allows finding new places to eat based on restaurant guests and their visit behaviour. The places, their geo-locations, and the guest data is read from the Gowalla API.

The map shows food places in Berlin, with the outer ring of the marker indicating the amount of visitors, and the inner circle size the total number of check-ins.

a) User selecting a restaurant. b) Food categories.

A user can explore the relations of a restaurant by tapping on its marker. Alternatively, the user can filter various categories to highlight the matching restaurants.
