Microsoft Hololens 2, like its predecessor, is an untethered holographic mixed reality (MR) headset that transforms the way we communicate, create, and explore. Hololens 2 advances MR ergonomics, intuitive interactions, and immersion. We describe the custom sensors and compute silicon developed to give hands-free user control of the headset and applications. With 3D Time of Flight (TOF) depth sensing, eye tracking and spatial array microphones, working with low power compute blocks aggregated in a custom ASIC, the hardware enables a comfortable, low latency user interface that sets the user free to focus on their work. We conclude with a look at how these building blocks can enable further innovation in the Intelligent Edge.
