Interesting Kinect features/behaviors

We got a Kinect a few weeks ago, and have really been enjoying it.  There are some interesting features/behavior of the implementation:

• You can sign into your Xbox Live account with facial recognition, but if you have a PIN on your profile, you will only be logged into your local profile, but not logged in online.


• While some games let use your avatar while playing, and some will use facial recognition to log into your account, I haven't seen any game that will correctly choose a show more than one avatar, when two people are playing.


• You are not able to use voice or hand controls to do everything in the dashboard.  For example:
  
  
  
  • You can't use voice or use your body to control Netflix playback
  
  
  • You can't open the DVD tray with your voice.
  
  
  
  


• You should definitely plan on redoing the KinectID calibration multiple times, to make the facial recognition work well.
