This is a video of Microsoft's interactive Holodesk 3-D See-Through Display. Using it, you can manipulate virtual objects with your hands. Unfortunately, you can't actually "feel" the objects, making this 3-D rendering of a titty I just spent the last 30 minutes making in AutoCAD virtually useless. Ha, notice how I said VIRTUALLY. *prints out IRL and tapes to pillow*
Microsoft's Holodesk combines a Kinect sensor and a beam-splitter to create a virtual 3D environment that you can manipulate with your hands. The concept is simple enough: a top-mounted projector displays an image downward towards a work area, and a piece of half-silvered glass sends that image towards your eyeballs while still allowing you to see what's going on. Placing your hands inside the work area lets the Kinect sensor see what you're doing, and the display dynamically updates to let you virtually interact with objects that aren't really there.
The key to the whole system is a webcam that tracks the location of your head and eyes to make sure that the orientation of the projection stays constant
OHMIGOD -- being able to move virtual blocks around with my fingers?! What is this, 2050? It must be -- when real-life wooden blocks are extinct. "I think you're missing the point." Which is? "Being able to interact wi-- DON'T YOU WIPE THAT BOOGER ON ME!"
Hit the jump for a video demo.
Thanks to Ponyboy, who at first I thought might be a centaur before realizing there's no way he could have sent such a well-typed tip with hooves.
