Hololens 2

In HoloLens 1, holograms were created by reflecting images from a screen in the headset into specially made lenses for red, blue and green light waves. Those light waves were then beamed into the back of your eyes, where your brain would create the final image. The device has a mirror known as a MEMS that moves fast enough to create the illusion of a screen in space. The MEMS creates 120 of these screens each second, filtered to the eye through lenses in the headset. The result is smooth movements, more-believable animations and quick response if you move your head

Overview

In HoloLens 1, holograms were created by reflecting images from a screen in the headset into specially made lenses for red, blue and green light waves. Those light waves were then beamed into the back of your eyes, where your brain would create the final image.

The device has a mirror known as a MEMS that moves fast enough to create the illusion of a screen in space. The MEMS creates 120 of these screens each second, filtered to the eye through lenses in the headset. The result is smooth movements, more-believable animations and quick response if you move your head.

There’s an 8-megapixel front-facing camera for video conferencing, and it’s capable of full 6 degrees of tracking, and it also uses USB-C to charge.

The device has a time-of-flight depth sensor, AI, and semantic understanding, and eye-tracking sensors that allows the user to manipulate holograms more naturally, which also means less learning curve to use the device.

HoloLens has speakers on the side, and you can lift the visor, just like a welding mask, to get to the real world without removing the headset. 

The headset is made of carbon fiber and the computing parts are on the back to make it more comfortable to wear, as the center of gravity is now in the middle of the head.

HoloLens 2 includes a Qualcomm Snapdragon 850 chip, the same technology powering most flagship phones on the market. And it more than doubles the field of view while maintain 47 pixels per degree of sight.
