Handwriting・WuXing is a multimedia interactive performance for the Leap Motion controller and Chinese calligraphy stroke gesture recognition system. In this composition, the composer not only to use hands’and fingers’ position data in 3D space reports by the Leap Motion, but combine those accessed data with Machine learning system to build a Chinese calligraphy stroke gesture recognition system, then to control and modify physical modelling sound and live-generate image (Max/MSP and DIPS) in real-time. Therefore, the hands’ movements in the air and dynamic gesture as well as live processing audio and video create lively intermedia experience to reveal the Chinese fivefold philosophy conceptual scheme of the five elements, or WuXing, as dynamic states of change, that many traditional Chinese fields used to explain a wide array of phenomena, from cosmic cycles to the interaction between internal organs, and from the succession of political regimes to the composition of arts.
