The role of Augmented-Reality in Tech:

Augmented reality is a technology that combines virtual reality with reality. In recent years, the rapid development of augmented reality technology has aroused people's high attention. This paper first expounds the research and progress of augmented reality at home and abroad.Secondly, it introduces the key technologies, development tools and application of augmented reality in some fields. Finally, it looks forward to the future development trend of augmented reality technologies such as AR cloud.
Introduction:
Augmented Reality (AR) technology is a technology that combines virtual information with the real 
world. The technical means it uses include Multimedia, 3D-Modelling, Real-time Tracking and 
Registration, Intelligent Interaction, Sensing and more.Its principle is to apply computergenerated 
virtual information, such as text,images, 3D models, music, video, etc., to the real world after simulation. 
In this way, the two kinds of information complement each other, thus achieving the enhancement of 
the real world [1].
In recent years, more and more internationally renowned research institutions, universities and 
enterprises have invested in the research of AR, published lotsof papers and scientific research results. 
These results demonstrate the feasibility and innovation of ARas human-computer interaction 
technology.With the improvement of computing power of computer software and hardware, ARhas 
gradually shifted from the theoretical research stage of the laboratory to the stage of mass and industry 
application, andas a bridge between the digital world and the real world, it provides people with a new 
way to recognize and experience the things around.In addition, it has been listed as one of the top ten 
most promising technologies in the future by authoritative organizations such as the American Times 
Weekly[2].In recent years, cloud computing has become a research hotspot in the Internet field. It can 
transfer storage and complex computing from the client to the cloud computing service environment, 
providing a possible distributed architecture pattern for complex interactive physical effects computing 
[3].
This paper summarizes the research status and progress of AR, discusses the key technologies, 
development tools, applications, AR cloud and other aspects of it,and finally puts forward the summary 
of the status quo and prospects for the future.
