Skeleton tracking without calibration (psi pose)

i would recommend using ofxOpenNI. you can get a user's skeletal data (limbs and joints), e.g. user.getJoint(JOINT_LEFT_HAND).getProjectivePosition().y

and send this data to quartz composer, ableton, etc, via OSC (see oscSenderExample).

good luck!

(note: i'm new to OF so there might be a better way to do this!)
