Dancing to music is done passively in conventional performances. Dancers or choreographers statically organize the choreography taking into consideration the flow and tempo of the music. Dancing configurations are static and it is difficult to change them in response to happening problems and the atmosphere. Up to now, dancers had only expressed themselves with bodily movements. However, if dancers were able to generate or control sound with their movements, a new style of performance would emerge.

[System description]

We created a system of dance performance that enables dancers to generate music while dancing, by using our sensor-equipped shoes. Our system not only generates sounds by dancing, but it also controls the scenario for the performance by changing the sets of sounds generated by motion commands. Dancers gain new dancing and musical expressiveness by using our system in dance battles. If one dancer is playing a drum-track by dancing, another is playing the bass line, and another is playing conga beats, i.e., they are playing music like a band.

we propose a new motion recognition method specialized to dancers. The key techniques are the motion recognition considering the beat of back ground music(BGM) to decide the recognition window adaptively and the two-phase motion recognition to fulfill the accuracy in high speed recognition.
