Augmented Reality (AR) is an area of computer science that allows programs to supplement the real world with artificial constructs. These constructs can take the form of static images, directions around an area, or even super imposing other environments on the existing one. By using AR, an app can simulate interactions with the real world in a virtual space. Android's solution to AR is ARCore, which lets most of the existing Android phones available execute AR apps with existing hardware. While this doesn't provide as much accuracy as custom hardware might provide (using the single camera on a phone compared to using two cameras to build a virtual understanding of the world), it makes AR technologies more accessible.
