The Microsoft HoloLens 2 is an AR headset that places the contents of your computer and phone into 3-D. The lenses of the HoloLens 2 uses sensors and cameras to track your movements and map the world around you. It can also track eye movements so that it can change what you see when you look around. You can play games in 3-D that look very realistic, for the images with appear right in front of you. You can also watch movies on big screens without actually having to look at a television. The Microsoft HoloLens 2 will help combine the virtual world into your world.

This is related to engineering because someone had to design the Microsoft HoloLens 2 and then develop it. They had to make it so that people can see things in 3-D through the lenses.
