problem is in kface.cpp:

FaceDriver::FaceDriver() {
  Kinect& device = Kinect::Device();
  HRESULT hr;
  for (int i = 0; i < kBodyCount; i++) {
    hr = CreateFaceFrameSource(device.Sensor(), 0, kFaceFrameFeatures, &face_sources[i]);
    hr = face_sources[i]->OpenReader(&face_readers[i]); //here occured the problem. 在这里发生的。
  }

//this is face_sources[] data:

原来脸部追踪是需要Kinect的另一个文件夹，NuiDatabase。详情如下文。
