VR, AR, MR, CR in the end how to distinguish?

 All know Micro LED technology for VR / AR, and VR, AR, MR, CR so much "R", in the end what is the difference?
The concept of universal
VR Virtual Reality
VR (Virtual Reality, referred to as the VR, also translated as spiritual environment, magic really) is a high-tech in recent years, and also known as Virtual Reality technology or artificial environment. Virtual reality is the use of computer simulations to generate a three-dimensional virtual world, providing the user to simulate visual, auditory, tactile and other sensory, allowing users as immersive general, in time, there is no limit to observe three-dimensional things within .
Augmented Reality AR
Augmented Reality (Augmented Reality, referred to as AR), also known as mixed reality. It is through computer technology, the application of virtual information into the real world, the real environment and virtual objects in real time superimposed on the same plane or spatial planning exist.
Mixed Reality MR
Mixed Reality (Mix reality, abbreviated MR), both including enhanced virtual reality and augmented, referring to merge reality and the virtual world and the emergence of new visual environment. In the new visualization environment where physical and digital objects coexist and interact in real time.
Systems typically employ three main features: 1 It combines virtual and reality; 2 in a virtual three-dimensional (3D registration); 3 real-time operation....
Images reality CR
As for the CR, is the concept of Magic Leap once preached, said he was Cinematic Reality, reality image, meaning that the virtual scene with the movie as realistic effects. But then if they themselves go spokesman also made a MR.
The difference between VR and AR
Simply put, virtual reality (VR), to see the scene and the characters are all false, is your sense of substituting a virtual world. Augmented Reality (AR), we saw some scenes and characters are really part of the false information is put into the virtual to the real world.
The interaction of the difference between VR and AR
VR equipment: Because VR is a pure virtual scene, the VR equipment is more interactive for the user to interact with the virtual scene, more use is: position tracker, data glove (5DT and the like), dynamic capture system, data helmet and so on.
AR Equipment: Because AR is a combination of real-world scenarios and virtual scene, so basically requires camera, cuttings based camera to take on the combination of virtual cuttings to display and interact with, such as GOOGLE GLASS these (in fact, strictly speaking, IPAD mobile phone these products only with a camera, can be used for AR, AR just install the software on it.)
The technical difference between VR and AR
Game-like production, to create a virtual world for people to experience it is to play graphics core of the technology. And we have the most contact is the application in the game, it can be said to be an upgraded version of the traditional game entertainment devices, focusing on whether the virtual scene has a good experience. The real scene is relevant, they do not care. VR machines are often submerged, the typical equipment is oculus rift.
AR applications a lot of computer vision technology. AR emphasize rehabilitation equipment visual function of the human, such as automatic tracking to identify the object, rather than to point out that I manually; independent tracking and the surrounding real scene 3D modeling, rather than do I open a Maya scene shining very similar. Typical AR device is normal mobile phone terminal, such as an upgraded version of Google Project Tango.
AR and MR distinction
In the above definition, AR is often seen as one of the forms of MR, so in the industry today, a lot of time in order to describe convenience or other reasons, but also put the AR as a synonym for MR, with the AR instead MR.
Furthermore, the concept of the industry in terms of advocacy, AR and MR and no clear dividing line, the future is likely to no longer distinguish between AR and MR. MR Hololens and more just played Magic Leap gimmick.
But now the so-called "AR device" and "MR device" from the display technology and applied, that was a little different, so we are still here to talk about the difference between these two types of devices (represented with Google Glass AR device to Hololens and Magic Leap, represented by MR device).
To better understand, we have to explain it in simple language, there are two main differences:
First, the relative position of the virtual object, if the device is moved with the movement. If yes, the AR device is, if not, that MR apparatus.
For example, wearing Google Glass, left it in front of you cast out a "weather panel," no matter how you move around the house, or turning the head, weather panel has been left in front of you, it is with you ( or GoogleGlass) relative position is unchanged, you go, where to put it with; and Hololens what is it, it will be projected on the walls of the house a weather panel, but the difference is that, regardless of how do you walk in the room, or turn the head, the weather is always the panel in that wall, it will not be because of your and moves
Second, in the ideal state (digital light field without loss of information), whether the virtual object and the real object can be distinguished.
Virtual objects created by the AR, is evident is virtual, such as the user's face FaceU play virtual items, Google Glass project a virtual moving information as you; and Magic Leap, the user sees the virtual object and real object is almost indistinguishable.
Of course, "AR device" and "MR device" is not absolute limits (even say that this limit is out of business YY), where they are put into these two categories, mainly so that we understand the technology they are applied and reach the effect is somewhat different. AR devices will use next SLAM, digital light field and retinal projection techniques (such as Google's Project Tango), then AR will evolve MR bar.
