The concept of VR must have been relatively clear for everyone, and it was here that we focused on the differences between AR, MR, and CR.
VitualReality, virtual reality, is the use of computing devices to simulate the creation of a three-dimensional virtual world, providing users with visual, auditory and other sensory simulations, with a full sense of "immersion" and "presence." As the saying goes, everything you see is computer-generated and fake. Typical output devices are Oculus Rift, HTC Vive, and more.
AR
Augmented Reality, Augmented Reality, literally means that “reality†is here, but it has been enhanced and enhanced by whom? Virtual information. The two typical AR systems are the on-board system and the smart phone system. The most discussed AR device is Google Glass.
Many cars have incorporated AR applications in their on-board systems. For example, GMC projects virtual images on its windshields. The intention is to allow drivers to keep their heads looking at the display and data of the meters, keep their heads up, and lower their heads and heads. Ignore the rapid changes in the external environment, as well as the need to constantly adjust the delay and discomfort caused by the focal length of the eye; or help the driver to better understand the road conditions and improve driving safety.
There are actually many applications on smartphones that belong to AR, but people often do not call them "ARs." For example, some LBS (geographic-based services) applications, when you open the application, the phone camera facing a building, the phone screen will appear on the screen of the building related information, such as name, floor, and so on. For example, FaceU, which used to be fired some time ago, is also considered an AR application. It captures the user's head in real time and superimposes virtual information such as "hat", "rainbow" and "rabbit ear" on the user's head.
GoogleGlass allows you to interact with the surrounding environment, will be through the glasses on the "micro-projector" to project a virtual image directly to your retina, so what you see is the real world superimposed on the virtual image. There may be doubts about basin friends, and where does it differ from Hololens and Magic Leap? Don't worry, keep looking down.
MR
When the climax comes, most of the potters should be confused by AR and MR (Mixed Reality, also known as Hybrid Reality). Let us first look at a picture.
I call this picture "reality-virtuality continuum" for the time being. The interval from left to infinity means “real-life environmentâ€, and then to the right are “AR†and “Augmented Vituality,†until right to infinity means “virtual environment†and “mixed realityâ€. It includes "augmented reality" and "enhanced virtual reality."
Augmented Reality (AR) is explained above, adding virtual information to the real environment to enhance the real environment; what is Enhanced Virtual (AV)? The same reason is to add the characteristics of the real environment in the virtual environment. For example, in racing games and shooting games in mobile phones, the direction and azimuth are adjusted by gravity sensing. Then, gravity sensors, gyroscopes, and other devices add features such as “gravity†and “magnetic force†in the real world to the virtual world. in.
Then the definition of MR is: the real world and the virtual world are mixed together to create a new visual environment. At the same time, the environment contains physical entities and virtual information, and must be "real-time." MR's two representative equipment is Hololens and Magic Leap.
How to distinguish between AR and MR?
Under the above definition, AR is often regarded as one of the forms of MR. Therefore, in the industry today, for convenience of description or other reasons, AR is also used as a synonym for MR and AR is used instead of MR.
Moreover, from the concept preached by the industry, there is no clear line between AR and MR. In the future, it is very likely that AR and MR will no longer be distinguished. MR is only a gimmick played by Hololens and Magic Leap. However, today's so-called "AR equipment" and "MR equipment" are still slightly different from the applied technology and display effect. Therefore, we still talk about the difference between these two types of equipment (represented by Google Glass). AR equipment and MR equipment represented by Hololens and Magic Leap).
In order to understand it, we just explain it plainly. There are two main differences.
First, the relative position of the virtual object moves with the movement of the device. If yes, it is an AR device; if not, it is an MR device.
For example, when you wear Google Glass, it projects a "weather panel" in front of your left. No matter how you walk in the house or turn your head, the weather panel is always in front of your left, it is with you ( Or Google Glass's relative position is the same, wherever you go, take it where it is,
And what Hololens is like, it also projects a weather panel on the wall of the house, but the difference is that no matter how you walk in the house or turn your head, the weather panel is always on that wall, it's It will not move because of your movement (this mainly involves spatial awareness location technology, SLAM, instant positioning and map construction, is one of the most important, the role is to allow the device to obtain the surrounding environmental information in real time, in order to accurately The virtual object is placed in the correct position, so no matter how the position of the user changes, the position of the virtual object can be fixed in the same position in the room.
Second, in the ideal state (no loss of information in the digital light field), whether virtual objects and real objects can be distinguished.
The virtual objects created by the AR device are obviously virtual. For example, virtual objects played by FaceU on the user's face, virtual information projected by Google Glass and moved by you; and Magic Leap, virtual objects the user sees. It is almost indistinguishable from real objects (here mainly digital light field technology, Digital Light Field. AR equipment uses two-dimensional display to display virtual information, so it is easy to distinguish between true and false; and MR equipment projects the entire four-dimensional light directly to the retina. Field, so the objects that the user sees from Magic Leap and see the real objects are mathematically indistinguishable and without information loss.)
Of course, the boundary between "AR equipment" and "MR equipment" is not absolute (even if the boundaries are from the enterprise YY). Here, they are divided into two categories. The main purpose is to let everyone understand the technology they are using and achieve The effect is different. AR equipment will also use technologies such as SLAM, digital light field, and retinal projection in the future (such as Google’s Project Tango). At this time, AR will evolve into MR.
As for CR, it is the concept that Magic Leap once advocated. It is Cinematic Reality. It means image reality, meaning virtual scenes are as realistic as movie effects. However, it seems that their spokesperson also referred to himself as MR.
It is also important that Magic Leap is not eye-sighted and should not be misled by the once-worshipping "whale video." Magic Leap also needs a head-mounted display. "Whale Video" should be a special effect in the later stages. Humanity hopes to see a virtual object out of thin air. It has been thinking for hundreds of years. There are many holographic images in the air in various science fiction movies. In fact, if you think about the nature, you know that it is physically difficult to achieve: There is no medium in the pure air that can reflect or refract light. The most important thing to show things is the medium.
Where "X" represents an unknown variable. This is awesome, give yourself a taste of the formula, XR = VR + AR + MR.
A relatively big feature of XR is that it will get rid of the remote control, and it is very likely to achieve a leap from the PC to the mobile terminal. This is a bit of a brewing point for the next mobile terminal to change. In addition, this is likely to be the key to the popularity of this technology in the future, but it is also XR's ambitions, making it more demanding on performance, requiring lower power consumption, smaller size, and greater scalability.
Unity released the XR Foundation Toolkit (XRFT) at the 2017 Game Developers Conference (GDC), which is defined as a framework for XR developers and allows anyone to join XR development. At the 2017 MWCS in Shanghai, Qualcomm once again mentioned the XR, and proposed that the implementation of the XR requires a complete ecological environment, including hardware and software. Taking into account the high-performance needs of the hardware, it is expected to directly from the latest Xiaolong 835 Start. In addition, XR can be applied to almost any field, and is no longer like when VR was just put forward. It has been misunderstood as a gaming machine for a long time.
