Nava Box / Motion Tracking
The Nava Boxes are six-sided virtual boxes controlled by a motion tracking camera. The boxes themselves are made from 5 improvised performances by Nava Dunkelman, who collaborated with me on the project and for whom the project is named. I have since collaborated with other improvisers to create their own "boxes," but I like the name Nava Box.
Raising hands and feet cause the boxes to move closer and farther away, with the associated change in amplitude. A movement of the hips can change the pitch of the video samples.
The result is a set of virtual cubes filled with improvised performances, which can be controlled using motion tracking.
I've also used motion tracking to change parameters in a video synthesizer, written in Jitter.
The possibilities are endless.
