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>

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>

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>

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>
