To say that the most popular technology in 2016, then it is VR and AR, they make people live and work more like Hollywood movies in the future, but how many people know what VR and AR are?
Below, Xiaobian will give you a popular science.
What is VR?
VR (Virtual Reality) is a high-tech technology emerging in recent years. Virtual reality is the use of computer simulation to generate a virtual world in a three-dimensional space, providing users with simulations of visual, auditory, tactile and other senses, allowing users to observe things in the three-dimensional space in a timely and unrestricted manner. Is a multi-source information fusion, interactive 3D dynamic view and physical behavior computer simulation system.
What is AR?
AR (Augmented Reality) augmented reality. Augmented reality is a technique for calculating the position and angle of camera images in real time and adding corresponding images, videos, and 3D models. The goal of this technology is to put the virtual world on the screen and interact with it in the real world. This technique was proposed in 1990. AR makes the real world and the virtual world "seamlessly integrated", and the physical information that is difficult to experience in the real world is superimposed by human beings through computer simulation, thus achieving the sensory experience beyond reality.
To put it simply, VR is to build a virtual world through computers to make humans perceive. The scenes and characters appearing inside are illusions. Your body is still in the real world, but your consciousness has entered another world. The AR is just the opposite. Some of the scenes and characters you see are really fake. It brings virtual information into reality and let us experience it.

When it comes to VR and AR, you have to mention another "R" - MR.
MR (Mediated Reality) mediates reality. It was proposed by Steve Mann, professor of the University of Toronto, the father of intelligent hardware. It includes both augmented reality and enhanced virtual, referring to the new visual environment created by the combination of reality and virtual world. In the new visualization environment, physical and digital objects coexist and interact in real time. The system usually adopts three main features: 1. It combines virtual and reality; 2. In virtual 3D (3D registration); 3. Runs in real time.
MR and AR are closer, they are half of the reality of half of the virtual image, but the traditional AR technology uses the prismatic optical principle to refract the real image, the angle of view is not as large as the VR angle of view, and the clarity will be affected. MR technology combines the advantages of VR and AR to better represent AR technology. At the same time, the large viewing angle of VR is integrated into the MR device, which can make up for the lack of perspective of the AR.
MR
Simply put, VR is a pure virtual digital picture, AR is a virtual digital picture + naked eye reality, and MR is a digital reality + virtual digital picture. The use of collection to understand is: AR and VR technology are a subset of MR, a pair of MR glasses can do AR and VR things, AR glasses can do VR things, and VR is VR.
MR 》 VR + AR
In the future, intelligent hardware will eventually transition from AR technology to MR technology, and the broad market prospect will inevitably enable global first-tier technology companies to join the research and development of VR equipment, which will inevitably promote the transition of VR to AR and MR faster.
