Augmented reality (AR) enhances real-world environments with computer-generated perceptual information. AR has many potential applications including advertising, tourism, education, and training. It works by displaying layered graphics and information over real world objects in real time using mobile devices and cameras. Popular uses of AR include shopping, travel, games, medical simulations, and maintenance assistance. Marketing with AR provides value when the content is highly relevant and engages users without being gimmicky.
