It is called because AR can instantly turn some inaccessible places into 3d, which is very real. Moreover, it can simulate trying on clothes, and can also use the high technology of face recognition to realize the user's choice of glasses and the like. It must be mixed with top technology and principles carefully introduced by scientists. Because to combine reality with virtual scenes, cameras are a necessity. As long as it is an electronic product with a camera, such as a mobile phone and an IPAD, AR technology can be realized by installing AR software.

Using AR camera products, users can interact with characters in the game in the real world. For example, the popular ar mobile phone game Pokémon and the "Call the World" activity of Yin and Yang teachers are all realized through mobile phone cameras. ? In large-scale events, stage theaters, concerts and other large-scale scenes. Virtual objects are perfectly superimposed on the real stage, and a three-dimensional spectacle mixed with fantasy and reality is presented to the audience through a big screen or projector. For example, the concerts of famous virtual singers such as Hatsune Miku and Tianyi Luo are all realized by AR technology.

Because VR is a pure virtual scene, VR devices are more used for the interaction between users and virtual scenes. More uses are position trackers, data gloves (5DT and the like), mobile capture systems, data helmets and the like. VR devices are often immersive, and the typical device is the Oculus rift.

Simply put, AR includes VR category, but AR technology is more advanced and more difficult to realize. With the development of science and technology, the boundary between AR and VR is becoming more and more blurred, and the two technologies are getting closer and closer, and there will be more and more intersections in the future.
