The difference between VR, AR, and Mr

VR, AR, Mr Definition: virtual reality, augmented reality, mixed reality

VR What is virtual reality?

Virtual reality (fictitious Reality, referred to as VR, also translated virtual reality, illusion) is a high-tech in recent years, also known as virtual reality technology or artificial environment. Virtual reality is the use of computer simulation to produce a three-dimensional virtual world, providing users with visual, auditory, tactile and other sensory simulation, so that users as immersive general, can be in time, unrestricted observation of the three-degree space of things.

The references in film and television literature are: "The Hacker Empire", "Inception", "Sword God Domain", "three Body" V-fixture.

VR Device representative: VR devices are often submerged, and typical devices are Oculus Rift.

AR What is augmented reality?

Augmented Reality (augmented Reality, referred to as AR), is also known as mixed reality. It uses computer technology to apply virtual information to the real world, with real environments and virtual objects superimposed on the same picture or space in real time. AR is partially overlapping in the current phase and holographic projection technology (Hologram): (In fact, Microsoft uses the word holo rather than AR in its AR device). Traditional Holographic projection technology refers to the use of optical techniques to achieve a complete, can be viewed from 360 degrees of virtual image, usually relying on multi-directional observation of multiple-face equipment and a number of different angles of projection to achieve, because this image is a true optical image, is open, many people visible, Therefore, it can also be visualized as ar/holographic technology for all.

The references in film and television literature are: "Minority Report", "Iron Man" Operation interface, "Solenoid coil", "Rainbow End".

AR Device Representative: Ordinary mobile phone, upgrade version such as Google Project Tango, Google glasses.

What is the mixed reality of MR?

Mixed Reality (mix reality, or Mr), which includes both augmented reality and augmented virtualization, refers to the new visual environment created by merging the real and virtual worlds. In a new visual environment, physical and digital objects coexist and interact in real time. The system usually uses three main features: 1. It combines the virtual and the reality; 2. In the virtual three-dimensional (3D registration); 3. Run in real time.

representative: HoloLens, Magic Leap Inc. (for Magic Leap products, Rony Abovitz describes it as a small, standalone computer that is comfortable to use in public. In addition, it involves retinal projection techniques. )

From the definition, we can see that the generality of VR and AR has at least two points, namely "3D" and "interaction". Without any of these, it cannot be called real VR or AR. This is why some scholars regard VR, AR as one of the reasons. This is because the VR and AR used in the construction of 3D scene technology and display equipment, the user experience is different, eventually leading to a different application direction. See table below:

Because the animation rendering technology can bring out all human imagination, so in the application direction, VR is more unreal and perceptual, more easy to use in the entertainment direction (in order to better achieve this goal, VR emphasizes the existence or the sense of telepresence); The technology based on optical +3d reconstruction is mainly to reproduce the real world, So AR tends to be more realistic and rational, easier to use in more serious directions, such as work and training (AR emphasizes true and virtual integration to better achieve this goal).

In short, virtual reality (VR), see the scene and the characters are all fake, is to put your consciousness into a virtual world. Augmented Reality (AR), see the scene and part of the character is true part is false, is to bring virtual information into the real world.

Interaction Differences

VR device: Because VR is a pure virtual scene, so VR equipment is more used for user interaction with virtual scene, more use is: Position tracker, Data glove (5DT, etc.), dynamic capture system, data helmet and so on.

AR equipment: Because AR is a real scene and the combination of virtual scene, so the basic needs of the camera, on the basis of camera shooting, combined with virtual screen display and interaction, such as Google Glass these (in fact, the IPAD, mobile phones These only products with the camera, can be used for AR, as long as the installation of AR software is possible. ）
