Augmented Reality and, in general, Mixed Reality combines the real world with a virtual scene and creates an immersive and interactive real-time environment. The possible applications are almost limitless and encompass areas like learning, architecture or industrial production. In the gaming area, AR/MR offers unique opportunities. Unlike with traditional video games, these games are not imprisoned onto the screen but interact with the real world. They incorporate real locations and objects into the game, therefore tapping into already existing thoughts and emotions of the player, which in turn creates a potentially much richer gaming world and experience. Mobile AR/MR Gaming even goes a step further as the playing area becomes borderless and games can be played literally anywhere and anytime. With the current advancement of modern cell phone technology, we are identifying the potential of Mobile AR/MR Games being played by anyone.
