View into the Congress Center of the Multimedia Forum Cologne.
Above the entrance a surveillance camera records the commuters.They can see themselves on a video wall, interace with sounds produced by their movements and play with geometries. Arrows indicate the direction of their movements, the diameter of the circles is growing with their speed. The green polygon describes the group of people within the scope of the camera. The turquoise polygon describes the interspace between two peoples. The pencil line represents the trace of one person during the last seconds.
