Introduction to VR, AR and MR Concepts _VR

In recent years, Vr/ar has been particularly hot, such as the previous E3 game exhibition, saw a clear trend: based on virtual reality or augmented reality of the new form of play, which is what we call the Vr/ar.

What is the future of VR/AR/MR?

In fact, the giants of Sony, Oculus, Microsoft, Google, Samsung and countless start-ups are developing virtual or augmented reality markets. Magic Leap technology company received Google 500 million U.S. dollars last year financing, and released a video in the WSJD exhibition, a lot of media called them as Mr Company, can see now ar/vr/mr everybody is doing, even several big internet companies have launched their own app and hardware equipment, Archie art, Youku, Lok-vision and other companies dedicated to video are also beginning to engage in virtual reality. So the outlook is good. Recently I also began to engage in virtual reality development, so from today began to update the theme of virtual reality, welcomed the small partners have friends to exchange.

Speaking of Vr/ar, even Mr, a lot of people may be more vague about the concept, then start from this concept, to talk about their differences, on the Internet another more professional explanation, about VR, AR, Mr Definition:

A. VR virtual reality
Virtual Reality (VR, Reality, virtual, unreal) is a high-tech in recent years, also known as virtual technology or artificial environment. Virtual reality is the use of computer simulation to generate a three-dimensional space of the virtual world, to provide users with visual, auditory, tactile and other sensory simulation, so that users as Urbanite general, can be timely and unrestricted to observe the three-degree space in the things.

B. AR Augmented reality
Augmented Reality (augmented Reality, referred to as AR) is also called mixed reality. It uses the computer technology, the virtual information to the real world, the real environment and virtual objects in real time superimposed on the same screen or space.

C. Mixed reality of MR
Hybrid reality (Mix reality, short Mr), both augmented reality and augmented virtualization, refers to a new visual environment created by merging real and virtual worlds. In the 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 with the reality; 2. In the virtual three-dimensional (3D registration); 3. Run in real time.

Again, the technical difference between VR and AR:

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), to see the scenes and parts of the characters are really part of the false, is to bring virtual information into the real world.

In profile, the left side of the picture is a VR device, the right side is an AR device, and 6 products are representative of their own field. In the above three sets of comparisons, we can clearly find that the overall volume of the VR device is larger than the VR glasses rather than the VR helmet is more appropriate. and AR products will be exquisite and small, the overall shape is also kept in the size of glasses, in addition to all equipped with transparent lenses, will also be equipped with cameras.

On the interaction, since VR is a pure virtual scene, VR equipment is more used for interactive interaction between users and virtual scenes, and the interaction of VR devices requires the support of external devices in addition to voice and gravity sensors, such as motion capture devices often used in film production perception Neuron, Oculus, Sony, HTC Vilve are all using virtual reality handles, position tracker, 5DT such as dynamic Data gloves, VR boxing equipment Impacto the EMG simulator used or a free moving real-world site like the Void theme park, the dynamic capture system, Data helmet and so on, relatively speaking, AR device interaction will be much simpler, AR is the combination of real scene and virtual scene, in addition to using the same voice and sense of the VR device, it also relies on the camera or micro-projection interface, based on the camera shot screen, combined with virtual screen display and interaction, such as Google Glass these (strictly speaking Pad, mobile phones, these smart products with cameras, can be used for AR, as long as the installation of AR software can).

At the technical level, similar to the game production, creating a virtual scene for human experience, the core is the graphics of the various technologies to play. The most involved are used in the game, can be said to be a traditional game entertainment equipment, an upgraded version of the main focus on whether the virtual scene has a good experience. They don't care if they're related to the real scene. VR devices are often immersed, and the typical device is Oculus Rift. AR uses a lot of computer vision technology, the AR device emphasizes the function of restoring human vision, such as automatically identifying the tracking object, instead of manually pointing it out, tracking and 3D modeling the surrounding real scene instead of me opening Maya to do a very similar scene. A typical AR device is a normal mobile phone, and an upgraded version like Google Project Tango.

In application positioning, the main application scenarios for VR devices are recreational activities, such as browsing videos, or "Traveling at home", as we have described in our previous news. The implementation of the method is also very simple, as long as the 360-degree camera to take VR video, with the head wearing equipment to watch can, here, such as 720yun such (interested can browse, not to advertise. Website address: 720yun). Slightly more complicated is in the game, in the game, in addition to the need for "equipment" and "content" outside, "interaction" will become particularly important, such as the well-known game "Eve:valkyrie", or HoloLens version of my world, etc. is such products. The position of AR is more abundant, except similar to "3D cubs", "sky plan" such games, there will be a lot of ancillary applications, such as shopping software "Ikea" home Guide; Real navigation software "casually go"; Measurement software "smart toolbox", translation Software "real translation", From these software we can also see that the AR device itself is widely positioned.

Finally, raise a chestnut:

For VR and AR, in science fiction and future science and technology in the application is also quite wide, I believe that the film will be a wonderful picture of the two technologies you have a deeper understanding, class VR films please refer to: "Matrix", "Three Bodies", "Inception" and "Sword God Domain", etc. ar Films please refer to: "Iron Man", " Minority Report, "solenoid coil" and so on.

The basic training on VR and AR is written here, then we intend to update some of the terminology of VR, AR, and so on, but also intend to study some image reverse malformations, how to reduce vertigo and other research stickers. Welcome everyone to discuss VR, want to know more about their own Google and Baidu, online resources are still a lot of.
