This principle was implemented in the Pokemon Go game: on the smartphone screen, you can see both the real surrounding environment and nonexistent objects - Pokemons - simultaneously. It is noteworthy that AR gadgets only make visual adjustments to what the user sees, and do not overlap the picture of the real world. The devices can further serve as applications that store and transmit information. There are four types of augmented reality devices in total: Virtual reality (VR) is the creation of a simulated environment that is completely different from the real one.
