This is an overview of the three installations Hoppsa Universum, CLOSE and Flying Carpet. They were all designed as choreographed sound and music installations controlled by the visitors movements. The perspective is from an artistic goal/vision intention in combination with the technical challenges and possibilities. All three installations were realized with video cameras in the ceiling registering the users’ position or movement. The video analysis was then controlling different types of interactive software audio players. Different aspects like narrativity, user control, and technical limitations are discussed.
