Microsoft unveiled the Avatar Kinect on Wednesday night during Microsoft’s keynote presentation at the Consumer Electronics Show in Las Vegas.

The new feature will let Kinect users interact with each other in virtual worlds with their avatars mimicking every movement on their body, including facial expressions. 

During the keynote, Microsoft CEO Steve Ballmer presented a video that showed off the service, which will allow up to seven friends to meet up in a virtual space.  There will be 15 virtual spaces, each with a different theme, including a performance stage and talk-show environment.

Avatar Kinect will be free for Xbox Live Gold members and is expected to be available this spring.
