The '''Microsoft HoloLens 2''' is an [[augmented reality headset]] built by [[Microsoft]] that uses an optical see-through display. It is marketed for enterprise workers who use their hands and can't benefit from phones, tablets, or computers in the same way that other industries can. Microsoft is targeting corporations like auto shops or factory floors to re-imagine the work environment. <ref name="alpha">https://www.theverge.com/2019/2/24/18235460/microsoft-hololens-2-price-specs-mixed-reality-ar-vr-business-work-features-mwc-2019</ref>

~~__TOC__~~

The HoloLens 2 has both hand and eye tracking capabilities. Hand tracking includes simplified gestures compared to the original HoloLens thanks to 25 points of articulation on each hand. Eye tracking includes the ability to pinpoint something with your eyes and verbalize commands, like closing a browser. Eye tracking is new to the HoloLens line. With a camera, the device can also scan your retina to authenticate you into the platform.<ref name="alpha"></ref>

~~==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~~

There are other notable improvements to the HoloLens 2 compared to the HoloLens. Not only can can it map the space you are in (spatial mapping), but it can understand the objects around you, like knowing that is a couch or a desk (semantic understanding of space). One reviewer noted it was more comfortable and easier to gesture, as well. The HoloLens 2 comes with a larger field of vision, though it's still significantly limited.<ref name="alpha"></ref>

~~compared to predecessor:~~

The HoloLens 2 also offers some new technology including the Azure Kinect DK and an ARM processor, mirroring a move across the tech industry away from Intel chips.<ref name="alpha"></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~~

Another reviewer noted the memory of the HoloLens 2 - it can save your browser exactly where and how it was if you move or leave. It can also remember where you've placed annotation in your environment.<ref name="beta">https://www.cnet.com/news/hands-on-at-home-with-microsofts-hololens-2/</ref>
