The article documents the theoretical and aesthetical basis of the interactive dance performance "man in |e|space.mov". The text discusses the abstraction of the human body in this performance by an interactive costume of light whose motion is analyzed by a 3D motion-rendering programme, which assembles and recombines the captured frame in real time in electronic 3D space. Thus appears a juxtaposition of 3 visions on the body making up the representation: the eye of the spectator, the camera and the 3D camera view: 3 visions constituting the contemporary body. Furthermore, the text questions the dislocation of the sensual body in physical space to the reading of body as a data in the matrix of virtual space in performing arts.In order to investigate the meaning of the aesthetics of abstraction, and dislocation of human body in performance art and motion analysis, the article puts 'man in |e|space.mov' in perspective to historical references of the 20th century, in particular to the work of the physiologist and pioneer of cinema J. E. Marey and the Bauhaus artist O. Schlemmer.
