Project HoloLens: Our Exclusive Hands-On With Microsoft's Holographic Goggles | WIRED

From a detailed HoloLens overview

"The headset is still a prototype being developed under the codename Project Baraboo, or sometimes just “B.” Kipman, with shoulder-length hair and severely cropped bangs, is a nervous inventor, shifting from one red Converse All-Star to the other. Nervous, because he’s been working on this pair of holographic goggles for five years. No, even longer. Seven years, if you go back to the idea he first pitched to Microsoft, which became Kinect. When the motion-sensing Xbox accessory was released, just in time for the 2010 holidays, it became the fastest-selling consumer gaming device of all time.
Right from the start, he makes it clear that Baraboo will make Kinect seem minor league."
