2010, touch less interactive globe, 175 years railway in Germany, Deutsche Bahn museum Nürnberg
The globe is a back projection of the earth. The globe can be rotated like a real one, by holding an spinning it. When the user taps/clicks points of interest on the surface an information window will open, showing facts from the global history of railway. He can close the window again or touch another point showing a second window. Well, actually the user doesn‘t need to touch anything, it is enough to hold the hand in front of the projection screen.
The application is implemented in C with OpenGL 2.1 and runs on Mac OS X and Linux. Detecting of touch gestures is done by the RadarTouch sensor, which sends OSC data to control the application.
