set-ups in the context of ys, similar to Reactable in eractive musical environ- osition of objects in space. s a fixed size surface and dentifier patterns that are em to control a range of musical parameters (volume, oscillator frequen- cies, rhythm etc.). My idea was to create a simple site- specific system where the interactive area was scalable, so that it could be enlarged as required to accommodate for objects or even people to interact (see Figures 1 & 2), and that would not depend on custom-built objects to trigger its parameters. Instead it would be capable of tracking sets of standard objects or human bodies in two-dimensional space without complicated mappings or pattern-recognition systems. This of course meant introducing sub- stantial limitations to the range of parameters that could be controlled, since the computer would only obtain X-Y spatial coordinates from each interact- ing element detected by an infrared camera system or Kinect. I felt this was enough for a basic musical interaction that explored the essential principles of sound and mu- sic-making since it could provide control over two fundamental pa- rameters: the pitch (X) and the amplitude (Y) of a variable number of sine wave oscillators. ➤ Index Photo:A.Santini2013A.Santini2013 LLA, Fuorisalone 2013, Milan, IT Photo:A.Santini2013 Figure 1: OSCILLA, Fuorisalone 2013, Milan, IT reate a simple site-specific the interactive area was at it could be enlarged as ommodate for objects or eople to interact…
