History of dance and technology is not only the story of digital dance. Digital dance was not born from nothing. I remember Annie Luciani presented at Imagina 1987 a kind of software about movement writing. Between 1985 and 1990, the body movement and the representation of dance were a thema of the conferences about computer graphics in Imagina . That was not directly digital dance but the preoccupations of engineers and movie industries were turning at this period for a part around dance... It was a beginning just before LifeForms. I think that digital dance story can also be linked to the theater story in general : "Deux ex Machina" (a god coming down the sky with the help of a machine, it was a way to finish unrelistic stories) in the roman theater, the baroque theater and opera machinery, the influence of industrial revolution on the arts, Lois Fuller and electricity, Nicolas Shoffer with his interactive Robot CYSP in a ballet created by Maurice Bejart in 1956 and a lot of examples nearer from us in the sixties and seventies... All this does not concern directly the digital dance but it could help us to understand what is digital dance artistically, technically and ideologicaly (technology can be understood as logos of the technics). All the best to all Philippe Baudelot
