Microsoft Research has really been hard at work with Kinect lately, and here's another one of its experiments.
The contraption in the video below is called the HoloDesk, and uses a projector, a Kinect and a 'beam splitter' to create the illusion that you're manipulating 3D objects below the sheet of clear glass.
Here's what MS says about the device: "HoloDesk is a novel interactive system combining an optical see through display and Kinect camera to create the illusion that users are directly interacting with 3D graphics. A virtual
image of a 3D scene is rendered through a half silvered mirror and spatially aligned with the real-world for the viewer.
"Users easily reach into an interaction volume displaying the virtual image. This allows the user to literally get their hands into the virtual display. A novel real-time algorithm for representing hands and other physical objects, which are sensed by the Kinect inside this volume, allows physically realistic interaction between real and virtual 3D objects."
This comes after MS Research last week showed how the Kinect could be used to turn any surface - from your hand to a wall or desk in front of you - in a touch-screen-style surface.
Fascinating stuff. Now, makes some games with it, MS.
