Radio Map, by Michael Hohl and Stephan Huber, is an immersive telematic environment that enables participants to walk about a projected photorealistic image of the Earth and listen to live internet radio programs that are located at the corresponding locations all over the world.
Once a person walks about the map, a graphic element is placed into the direction of movement. Called the PoI (Point of Interest), it is used to select radio stations. Should more participants enter the space, all their lines connect to this single element, creating a shared PoI, which is placed in the calculated middle of all participants.

If the PoI is located between two or more stations that are close together their signals would mix. This creates potential for surprising "mixing" of the sound. Yet participants are always able to accurately
