AR and VR

1. AR VS VR

AR, augmented reality, is when the a 3-dimensional world is overlaid digitally using some sort of technology. Examples include Pokemon go, where pokemon could be seen when your phone was aimed in the correct place.

VR, virtual reality, is a completely digital world created by a device. They are controlled by the user's movements, such as when their head turns, the digital world turns with them. Examples include the Oculus rift.

2. VR is being used by doctors to construct digital versions of bodily scans so they can be 3 dimensional and easier to view. Then, these scans can be used for virtual training.

Museums are using VR to make their experiences better, as users can be transported to a museum in their own home. The British Museum in London and the Natural History in NYC have already started this.

For augmented reality, construction companies are looking at ways of "blowing up" items to further see how they could fir into the real world. Other uses include mapping pipes across places where they are planned to be.

Sports games, especially football use augmented reality and we don't even realize it. The lines across the field in sports games are all augmented on the screen by computers.
