Creative use of signal processing and MARF in ISSv2 and beyond

Abstract

Illimitable Space System (ISS) is a real-time interactive configurable toolbox for use by artists to create interactive visual effects in theatre performances and in documentaries through user inputs such as gestures and voice. Kinect has been the primary input device for motion and video data capture. In this work in addition to the existing motion based visual and geometric data processing facilities present in ISSv2, we describe our efforts to incorporate audio processing with the help of Modular Audio Recognition Framework (MARF). The combination of computer vision and audio processing to interpret both music and human motion to create imagery in real time is both artistically interesting and technically challenging. With these additional modules, ISSv2 can help interactive performance authoring that employs visual tracking and signal processing in order to create trackable human-shaped animations in real time. These new modules are incorporated into the Processing software sketchbook and language framework used by ISSv2. We verify the effects of these modules, through live demonstrations which are briefly described.
