Motion capture (markerless) live performance

Hello,

I'm looking for a low cost method of motion capture (markless) live. What I'm trying to get is a LIVE performance with a video output like this:

https://youtu.be/mAKveiQ--ys?t=2m48s8 (2min: 48)

which a 3D avatar can simulate in real time (or near) the movement of the performer.

The performer will dance in a space of approximately 4x4 meters For the mocap I'd like to use PSeyes or Kinect for their cheapness.

I'm looking for an efficient way to do it and i'm not a user with great experience in Unity. Any advices or good examples are welcome :)

Thank you so much in advance

Donald
