Very Nervous System

This video shows the interactive sound installations created by David Rokeby. About this sound installation David Rokbey said

The first major interactive work I created is called «Very Nervous
System» and was started in 1982. I use video cameras, image processors,
computers, synthesizers and a sound system to create a space in which
the movements of one’s body create sound and/or music. The computer as
a medium is strongly biased and so my impulse while using the computer
was to work solidly against these biases. Because the computer is
purely logical, the language of interaction should strive to be
intuitive. Because the computer removes you from your body, the body
should be strongly engaged. Because the computer’s activity takes place
on the microscopic scale of silicon wafers, the encounter with the
computer should take place in human-scaled physical space. And because
the computer is objective and disinterested, the experience should be
The result is an interactive space in which the public uses their
bodies as the active element of the interface. Body movement is rich,
complex, and full of subtlety and ambiguity. Early computer art used
random number generators to provide variety and complexity. I replaced
the random number generator with the complexity of sentient human
