HoloLens is fully untethered and self-contained. It’s the only device that enables holographic computing natively with no markers, no external cameras, no wires, no phone required, and no connection to a PC needed. And it’s a Windows 10 device – the interface is familiar, and connected by the power of a unified ecosystem of Windows devices.
The device consists of multiple environment understanding sensors and it’s powered by a custom-built Microsoft Holographic Processing Unit (HPU) and an Intel 32-bit architecture. The HPU is custom silicon that allows HoloLens to understand gestures and gaze while mapping the world all around you, all in real time.
Microsoft today announced that the Microsoft HoloLens Development Edition will start shipping on 30 March, at $3000 a piece. They also offer a look at the hardware powering HoloLens.
