Augmented Reality (AR) is a technology that augments a view of the real world with digital information or objects using devices such as smartphones, tablets, computers, and smart televisions. AR enables users to augment their view of the real world with text, images, and three-dimensional objects. AR applications include gaming, learning, and design, among others. This distinguishes augmented reality from virtual reality, where the observed environment is completely artificial and distinct from the real world.
