2012-11-13 02:27:57 -0500 | asked a question | Kinect for Windows - No Device connected Hey :), i got some issues using a Kinect for Windows. I find out that this Kinect is not supported by Openni yet. here and here and this command: throws an error like this: I tryed to use the unstable version of openni and ps-engine as mentioned at this question but this sill not works. So the real Question whitch arives. Is there some kind of workaround for this issue? for advising purposes: The easy solution for this issue was just to take an older Version of Kinect. |
