Kinect NUads system shown in video
Microsoft's released a video of its Kinect NUads system in action. NUads is a gesture- and voice-based ad system for Kinect that allows you to interact with advertising by tweeting, getting more information on the products you're looking at, and so on.
There's no date on when this is going to go live, but "pretty soon" is a safe bet. Check it out below.
