Microsoft HoloLens is a smart-glasses headset that is a cordless, self-contained Windows 10 computer. It uses advanced sensors, a high-definition stereoscopic 3D optical head-mounted display, and spatial sound to allow for augmented reality applications, with a natural user interface that the user interacts with through gaze, voice, and hand gestures. Codenamed "Project Baraboo," HoloLens had been in development for five years before its announcement in 2015, but was conceived earlier as the original pitch made in late 2007 for what would become the Kinect technology platform.
Microsoft expects HoloLens to be made publicly available "in the Windows 10 timeframe,"with a v1 HoloLens—intended for developer and enterprise uses—to be released "within the next year" of the initial Windows 10 launch. An unnamed Microsoft executive said that HoloLens would cost significantly more than a video game console.
