How to get the Kinect joint data(x,y,z)

Hi everybody! I'm a newie on using kinect and Unity.I have a goal for showing every joints of the kinect skeleton's coordinate on the corner on the screen,similar to this video,https://www.youtube.com/watch?v=E9cZHStQcYM , it has the joint information in the left upper corner. I have some trouble on working on this.First is that OpenNI,Primesense and NITE have stopped updating, so when I went through many articles, many of them are out of use. The video that I linked has the same problem that OpenNI and OpenNI for Unity is out of order.

Is there any other way that I can get the (x,y,z)data of the joints? Thanks for helping :)

My devices are as below: Kinect v1, Kinect sdk 1.8, Win7(32bits), Unity4.6

P.s If anyone has resources for learning Kinect on Unity,please tell me! I'm eager to learn more about this.
