We currently have access to the facial data in a prototype build of K4U. We were contacted by Sirenum Digital about their game The Lost Pisces which requires reading the facial data from the Kinect and have successfully gotten the facial animation data among a few other things. The general state of the Kinect’s API in that area is best described as interesting and the data it outputs requires a lot of fiddling to get into a usable fashion (the eyebrows for instance randomly set their zero point between .4 and -.2). Once we are happy with the quality of nodes, examples and documentation we have produced we will be releasing it.
However a note with any of the extended libraries is that they require people to move files from the Kinect SDK install directory into their system32 directory, which is why some of the basic functionality hasn’t already been included as it could cause crashes and instabilities in everyone who hasn’t explicitly set up their face libraries.
