You're probably talking about Mova. Facial motion capture (of that quality) is very different from full body motion capture since the face has so many more degrees of freedom. So generally it is done in an extremely controlled environment with many simultaneous cameras and specific lighting and very little head movement. The problem with doing high quality real time performance capture at home is you can't control the lighting or occlusion - sometimes even a human looking at the footage won't be able to discern what's going on. Not to say it won't ever happen but it will require extremely significant advances in computer vision.
