Using the Gesture and Media System 3.0 (GAMS) motion tracking system, the performer can dynamically manipulate a complex immersive environment using two small infrared trackers. With the FlashTrack 3D mapping software, single note melodies, drum hits, samples, light effects and images can be programmed to be triggered anywhere in 3D space. Individual parameters (filters, reverb, delay, light colour, image brightness, etc.) can be altered in real-time using changing x, y or z coordinates or velocity. Conceptually OPK makes a case for physically-engaged interaction in response to much of present-day ‘lazy media,’ while at the same time the piece subtly references possible damaging uses of those technologies.
