Fiducials & Optical Flow

Probably sounds like something an Eye Doctor would tell you to wash out with saline. We chose to design interaction around these two key types of input. We'd use printed fiducial markers to very concisely trigger musical instrument sounds which would be pitch and tempo mapped to the music. We'd use camera optical flow and general activity to control more atmospheric and textural aspects of the music like filter cutoffs and delay pings. In order to deal with this composite computer vision, our CV programmer Brian ended up compiling a custom hacked version of reacTIVision.
