What are the meanings of virtual reality and augmented reality?

Virtual reality is a closed, independent and completely virtual space. Immersive experience will isolate your visual interaction with the outside world, so it is more suitable for playing cross-scene remote operation at home. Augmented Reality (AR) is a new technology that integrates real world information and virtual world information. It is through computer simulation and other science and technology, the physical information that is difficult to experience in a certain time and space in the real world is superimposed and applied to the real world.

Virtual reality is widely used in the entertainment field at present, probably because the application of technology has not been shaped or its potential has not been tapped. Film and television also have earlier application fields. Watching videos with VR eyes gives you an immersive feeling. Well, you don't have to go to the cinema to see the 3D screen. Virtual reality can be applied to the military. The data of mountains, rivers, landforms, oceans and lakes on the map are compiled by computer. Using virtual reality technology, the original plane map can be changed into three-dimensional topographic map.

Augmented reality has been widely used recently, and it seems to have unlimited possibilities. For many years, augmented reality software based on mobile phone has been identifying the surrounding environment, providing additional information it sees, providing real-time translation of text or pop-up comments when you see a restaurant, and so on. Special augmented reality glasses can do more. You can virtually place floating windows of different applications in the surrounding space, just like multi-monitors in the real world.
