Does anyone know how to derive the speed and acceleration from position data coming from a Webcam or Wii or Kinect ?
I get x,y,z position date from the Kinect and I would like to get the speed and acceleration of my movements.

Any ideas ?
Thanks a lot !

But then there’s this nifty [mnm.delta] object in the FTM library that does it all for you: http://ftm.ircam.fr/index.php/Main_Page
