Solutions for iOs camera body tracking?

Was wondering if anyone has had success with body tracking or interaction with the live camera feed from an iOs device. I am looking for interaction like this http://www.tadamiplayground.com/. I have found some Windows only solutions for Unity (Omek motion) but nothing for iOs. I have experience with the Vuforia AR SDK but not sure if that could be used for this kind of interaction. Thanks.
