Augmented Reality (AR) has rapidly come to prominence in the last few years. At its simplest, it is using a device to project something computer-generated into the real world. It’s not replacing the real world as virtual reality does. There are two primary types of AR devices. There are wearable devices which depend on the human to wear them, and by detecting what the human is sensing it creates additional graphics, sounds, etc. The second type is an AR projector. This is a device that projects light into the real world in such a way that anyone nearby can see it.
