i finally found something useful to do with my kinect: tracking the neck of a guitar and using gesture recognition to control the FX rack of a pure data patch.
Guitar neck tracking
i am using the neat gesture recognition toolkit by Nick Gillian. using the DTW (Dynamic Time Warping) example (coded in openframeworks), i simply added open sound control to send the predicted gesture to pure data. you can download the source and the executable for linux (64bit).
nothing fancy here, just a patch to send the tracking via osc to the gesture recognition i get back the result from it, apply some FX to an incoming signal using X, Y, Z. you can download the patch.
