__TOC__
The '''Microsoft HoloLens 2''' is an enterprise [[mixed reality]] [[head-mounted display]] developed by [[Microsoft]], announced on February 24, 2019 and released on November 7, 2019 at $3,500. The successor to the original [[Microsoft HoloLens]], the HoloLens 2 features more than double the field of view (52° diagonal), improved display quality with 47 pixels per degree, advanced articulated hand tracking with 21 points per hand, eye tracking with iris recognition, and a more comfortable flip-up visor design. Powered by the Qualcomm Snapdragon 850 and Microsoft's second-generation Holographic Processing Unit, the HoloLens 2 became the industry standard for enterprise AR applications in manufacturing, healthcare, and defense.
==Introduction==
for folks older than 13
retinal scan for authentication
not positioned as consumer product, though anyone can purchase one
for employees using their hands at work, not stuck at computers/desks (factory floors, fixing jet propulsion engine
you can wear glasses with them


== History and Development ==


compared to predecessor:
Microsoft announced the HoloLens 2 at Mobile World Congress on February 24, 2019, addressing key criticisms of the original HoloLens including its limited field of view and comfort issues. The device launched on November 7, 2019, targeting enterprise and military customers rather than consumers. Microsoft secured a significant contract with the U.S. Army for the Integrated Visual Augmentation System (IVAS) based on HoloLens technology.<ref name="roadtovr">{{cite web |url=https://www.roadtovr.com/hololens-2-specs-resolution-field-of-view-battery-life/ |title=HoloLens 2 Specs: Resolution, Field of View, Battery Life & More |publisher=Road to VR |access-date=2025-01-07}}</ref>
more comfortable, large field of view, easier gestures, better detection of real-life objects, more accurate hand tracking
new: Azure Kinect sensor, an ARM processor, eye-tracking sensors, and an entirely different display system
