In Urban Fabric, dancers, musicians and media artists are accompanied on stage by projected visuals. The Active Space intermedia performance system processes live onstage camera feeds combined with footage shot on location and an architectural rendering of Calvino text. The movement of the dancers directly influence the video and audio accompaniment generated by the system. A video-based motion tracking component recognize various characteristics of the dance performance. The results of this analysis influence the behavior of two real-time interactive visual composition systems; one for visuals and one for sound. Responding to the movement of the dancers, the composition systems produce synthesized video and audio, combined with non-linear playback of clips and samples.
While the performance by the dancers is the center of the piece, the media artists are performers as well. However, they do not explicitly “play” or manipulate instruments or devices to produce visuals and sound. Instead, they watch the dance and continually monitor the interactive behaviors of the computer-based music and video composition systems, listening and observing how software responds to the movement of the dancers. As the media systems play, the media artists make adjustments to parameters and algorithms, tuning the media behaviors, shaping the responsiveness to the circumstances of the dance.
As dancers and media artists interact with the Active Space environment, its responses and behaviors become construed as mechanisms for communication. The media system itself becomes a message, or a series of messages, an embodied sequence of codes, exchanged among performers and between performers and audience.
