First Avatar Kinect trailer

See how Microsoft's new online chat service works

Here's the first trailer for Avatar Kinect, the online Xbox 360 chat service Microsoft unveiled during the Consumer Electronics Show earlier this week.

The face-tracking service will allow users to directly control their Xbox Live avatars using Kinect, with the motion sensing peripheral translating facial movements such as smiles and raised eyebrows.

The video shows MS CEO Steve Ballmer introducing and using the technology at CES, followed by the first Avatar Kinect commercial.
