The HoloLens is the most impressive augmented reality headset on the market today, and their developer kit is already being deployed into industries ranging from architecture, engineering, design, sales, medicine, and education. Microsoft is taking a holistic approach with Windows Mixed Reality being baked into Windows 10, meaning that developers can create a single application that can run on the HoloLens, on one of their partner VR headsets, on a Surface tablet, or as a desktop app. At Microsoft’s Build conference today, the company is announcing a new OEM VR partner with HP as well as inside-out, six degree-of-freedom input controllers for VR headsets made by Microsoft partners like Acer.
