Augmented reality is a brand-new human-computer interaction technology. With this technology, real scenes can be simulated. It is a computer advanced man-machine interface characterized by interactivity and conceiving. Users can not only feel the "immersive" realism experienced in the objective physical world through the virtual reality system, but also break through the objective limitations such as space and time, and feel the experience that cannot be experienced personally in the real world.

Augmented Reality (translated from Chinese into Augmented Reality) has recently appeared more and more on the Internet. Augmented reality can be regarded as a kind of virtual reality, but slightly different is that virtual reality creates a brand-new virtual world, while augmented reality emphasizes the combination of reality and reality.

1. Combining reality and virtuality

2. Real-time interaction (instant interaction)

3. Register in 3d < 3d Positioning >

To realize the combination of reality and reality of AR, users must watch it through a certain device. Most of the previous studies were mainly through HMD.
