Keynote: Live Demo
HoloLens is totally wireless and untethered. It has a CPU, GPU, and "Holographic Processor" built-in, and it doesn't need to sync to a smartphone or desktop. You control it using gestures or your voice, and it also follows your eye movements. It doesn't incorporate a heads-up display like Google Glass has. Instead it creates holographic screens and objects that look like they're in the environment around you. Microsoft also says that the headset provides surround sound.Microsoft says it will release HoloLens around the same time as Windows 10 later this year, so the device seems to be more than a prototype pipe dream.
