This article presents a framework for real-time analysis and visualization of ballet dance movements performed within a Cave Virtual Reality Environment (CAVE). A Kinect sensor captures and extracts dance-based movement features, from which a topology preserved "posture space"' is constructed using a spherical self-organizing map (SSOM). Recordings of dance movements are parsed into gestural...
