In addition to a high-tech grocery cart and an augmented-reality mirror, one of the futuristic projects on display at Microsoft’s TechForum event earlier this week was a research project exploring the possibilities for using a transparent LCD display in conjunction with a Kinect sensor to let people interact with virtual objects in a 3D space by moving their hands around behind the screen.

Yes, it might sound a little crazy, but it works, and it might actually have some practical applications.

See it in action in my video above, with Stevie Bathiche, director of Microsoft’s Applied Sciences Group, introducing the project, and former Microsoft intern Jinha Lee, a PhD student at the MIT Media Lab, giving the demo.

Also see this Microsoft video below with Lee and Microsoft researcher Cati Boulanger.
