Augmented Reality is the technology that expands our physical world, adding layers of digital information onto it. unlike Virtual reality, AR does not create the whole artificial environments to replace real with a virtual one. AR appears in direct view of an existing environment and adds sounds, videos, graphics to it.

AR can be displayed on various devices: screens, glasses, handheld devices, mobile phones, head-mounted displays.

From social media filters to surgical procedures, AR is rapidly growing in popularity because it brings elements of the virtual world, into our real world, thus enhancing the things we see, hear, and feel. When compared to other reality technologies, augmented reality lies in the middle of the mixed reality spectrum; between the real world and the virtual world.
