Microsoft is letting developers pre-order the HoloLens development edition today, but it's also detailing exactly what's inside the headset. HoloLens is fully untethered and self-contained, which means you do not need a PC or phone to use it. Microsoft has built an entire Windows 10 device into a headset, using a custom-built Microsoft Holographic Processing Unit (HPU) and an Intel 32 bit processor.
Microsoft has a variety of sensors inside the HoloLens, including an inertial measurement unit, an ambient light sensor, and four environment understanding cameras. These combine with a depth sensing camera to allow HoloLens to map spaces. Microsoft also has a 2-megapixel HD camera to capture videos and photos. Four microphones inside the headset are used to pick up voice commands from users.
Microsoft has a Bluetooth clicker accessory
HoloLens hardware specifications include 2GB of RAM, 64GB of flash storage, and Bluetooth and Wi-Fi connectivity. The Bluetooth support allows HoloLens owners to make use of a new Clicker accessory, included in the box, instead of the air tap gestures to navigate around. Microsoft says the entire HoloLens headset will weigh no more than 579 grams, and the battery will run for around two or three hours of active use. HoloLens is fully functional when it's charged over Micro USB, and the device will also have a standby time of two weeks.
A carrying case will house the HoloLens, Clicker accessory, charger, and additional nose pads. Microsoft also released a final image of the HoloLens development edition, and it looks identical to the units the company has been testing over the past six months. Microsoft will start shipping HoloLens development devices to developers on March 30th, priced at $3,000.
