Kinetica (Improvisation dance Japan)@Kurashiki Sakuyou University-Rehearsal-2004,Japan

Works by Chikashi Miyama（美山 千香士）
Performed by Katsutoshi Mizukawa (Dance)（水川 勝利）

"Kinetica" is a work for a dancer
and an interactive multimedia system,
consisting of three networked
Macintosh computers. A dancer on
stage realizes a dance improvisation
in front of the screen where the
animated computer generated image
is projected. The dancer listens to the
electroacoustic sound and controls
the computer synthesized sound
diffused in the hall. One of the three
computers detects the dancer's movements and position on the stage using the video analysis program SoftVNS that
was implemented as a set of Max objects. The SoftVNS objects convert the dancer's motion into numbers in the Max
patch. These data, along with cues, are sent to the two other computers via ethernet using OpenSoundControl, and the
interaction among a dancer, computer generated sound and projected images is realized. Responding to the incoming
data from the computer running SoftVNS, various computer sound synthesis and signal processing techniques such as
subtractive synthesis, formant synthesis, granular sampling, and harmonizing are realized with SuperCollider 2. The
computer for sound also controls the image processing sending data to the other computer via ethernet. The computer
running DIPS generates 2D and 3D animated graphic images in real-time. These images are projected to the screen
behind the stage with the dancer's silhouette.
