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.
