Taking advantage of our new time-of-flight depth sensor, combined with built-in AI and semantic understanding, HoloLens 2 enables direct manipulation of holograms with the same instinctual interactions you’d use with physical objects in the real world. We have also completely refreshed the way you interact with holograms in HoloLens 2. HoloLens 2 contains a new display system that enables us to achieve these significant advances in performance at low power. We have more than doubled the field of view in HoloLens 2, while maintaining the industry-leading holographic density of 47 pixels per degree of sight. Immersion is greatly enhanced by advancements across the board, including in the visual display system, making holograms even more vibrant and realistic. The Microsoft blog describes the 3 pillars of HoloLens 2 development:

The HoloLens 2 includes improved sensors, a better display, improved ergonomics and more. Costing an eye watering $3,500 or $150/month, the HoloLens is not a mass market or consumer device. Today at MWC 19 in Barcelona, Microsoft announced the second release of their HoloLens augment reality headset.
