Very informative! Just a few weeks ago I tried out ZigFu and really liked it. I&apos;m sorry to hear the team has left. But I hope, ZigFu keeps being successful, even if not in the VC sense.&lt;p&gt;In my humble opinion, one, if not the biggest problems is, that the Kinect is just not good enough, yet. My experience is, that the Kinect works well for the T-pose and anything that resembles it, but not well or at all once your arm is pointing towards the Kinect.  
Here [1] is a recent paper, with the most detailed validation of the MS Kinect I have seen so far. They report a  maximum error for reaching movements with OpenNI of &lt;i&gt;46.9 deg&lt;/i&gt; in the elbow angle estimation.
Another problem is lag. From what I hear, the main problem here is the USB 2.0 bandwidth. Hopefully the next generation, Kinect 2 and co., will improve a lot.&lt;p&gt;[1] S Choppin, J Wheat , 2012, Marker-less tracking of human movement using Microsoft Kinect

Taking a few wrong turns doesn&apos;t need to be the end and you seem to have learned a number of valuable lessons.</text></comment>
