| Summary: | 碩士 === 國立臺北科技大學 === 互動媒體設計研究所 === 101 === Traditionally, a choreographer will arrange steps and movements for a dance using existing music, or he/she might cooperate with a composer and have him/her write new music according to the dance script. But both the two choreography procedures require dancers to follow the music to achieve synchronization, and thus require dancers to spend a lot of time practicing repeatedly in order to be able to keep their body movements in synch with the music. With this " Embodied Interactive Music System", dancers can use their body movements to control the interactive music system and to produce corresponding music, and even to incorporate the impromptu elements in the dance without affecting the synchronization between the music and the dance. In addition, because the embodied interactive music system was built on a modular programming environment framework and can produce different music pieces according to different dance scripts, therefore it possesses expandability.
This research uses the object-oriented video-audio program design system Max/Msp/Jitter as the design platform for the interactive system. The system utilizes Microsoft Kinect sensors to detect dancers'' body movements, and to uses Kinect''s depth sensing function and the Open NI middleware to construct the coordinate values of the joints of the person being detected. It further adopts the 8 basic movement efforts in the Laban Movement Analysis as the embodied interactive system''s analysis guidelines in identifying, in real-time, dancers'' body movements at the moment, and together with a sequence setting mechanism to control real-time sound synthesis or to trigger the playback of the pre-recorded sounds.
The usability of the interactive system designed in this research was tested, evaluated, and verified by experts. The creative works of this research were also checked against the design principles of embodied interactive music system summarized through the collected opinions from various experts in the related fields. At the last, researchers reviewed the system''s design history and its performance application processes, conducted inductive investigation on related research results, and offered concrete conclusions and suggestions.
