Interactive Installations : Body Language (1984-6)
Financially assisted by the Canada Council for the Arts and the Ontario Arts Council

hand-built cameras, processor for Body Language (1984)

Body Language represents the second generation of interactive sound installations I created.The installation used three hand-built low-resolution (8x8 pixels) video cameras (see image above) to observe a 5 metre by 5 metre space. The images from the cameras are digitized by a system that used 3 6502 processors in parallel. This information about motion was relayed to an Apple ][ computer. The computer searched for movements in these images, analysed them and created sounds in response, simultaneous to the movement itself. The sounds were produced by custom software running on a Mountain Hardware Digital synthesizer sitting in the Apple ][. Any movements made by people within the space create sounds whose qualities reflected the qualities of the movements. (Next)
