Apparition uses interactive technologies to release the performer from the determination of set choreography. Through digital media performance software, it generates the video and sound content in real-time.

The camera based motion tracking system developed for Apparition uses complex computer vision algorithms to extract the performer’s moving outline/shape from the background to provide constantly updating information for a body projection as well as qualitative calculations of certain motion dynamics, e. g. speed, direction, intensity and volume. The information derived from these calculations is assigned dynamically to the real-time generation of visuals that are projected either directly back onto the body and / or as large scale background projection. The precise synchronisation of projections on the background and the bodies results in the materialization of an overall immersive kinetic space.

The real-time system for generating visuals developed for Apparition is built on top of computational processes that model and simulate real-world physics. The inherent kinetic properties of these simulations inspired our view that the overall interactive system is much more than simply an extension of the performer; it is a potential performing partner. The independent behavior of the physical models ,for example, is not “controllable” by the performer, but can be influenced by his or her movement.
