What is the function of Apple's mobile phone AR?

Ar (Augmented Reality) is augmented reality. Augmented reality technology is a kind of technology that skillfully integrates virtual information with the real world. It widely uses multimedia, three-dimensional modeling, real-time tracking and registration, intelligent interaction, sensing and other technical means to simulate computer-generated virtual information such as words, images, three-dimensional models, music and videos and apply it to the real world. The two kinds of information complement each other, thus realizing the "enhancement" of the real world. There are many new technologies and means in augmented reality technology.

Extended data:

Augmented reality technology can not only effectively reflect the content of the real world, but also promote the display of virtual information content. These fine contents complement each other and overlap each other. In visual augmented reality, users need to overlay the real world and computer graphics on the basis of HMD in order to fully see the real world around them. There are many new technologies and means in augmented reality technology, such as multimedia, 3D modeling and scene fusion. The information content provided by augmented reality is obviously different from that perceived by human beings.
