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.
