what are the basic characteristics of VR?

Not open for further replies.
With the development of the times, people are no longer satisfied with the exploration of the real world, and have started to explore the stage of mixed reality (MR). MR has made considerable technological progress in 2022 today. So, at this stage, compared with VR technology and AR technology, which technology can detonate the MR market faster? Before discussing this issue, we must first understand what is VR technology, what is AR technology, and the difference between them.

So what are the basic characteristics of VR?

VR technology first emphasizes the "three Is" - immersion "immersion", interactive "interaction", and imagination "imagination". It focuses on reflecting the leading role of the experiencer in the VR system, adjusting the processing of information to suit people's needs and consistent with people's senses.

Generally speaking, VR technology is to create an interactive virtual environment that transcends reality. In order to enhance the user's sense of immersion, the general VR equipment is mainly three-dimensional projection and helmet display, etc., although there are still technical problems As a result, VR technology cannot achieve true "virtual reality", but the author believes that with the development of the times, these problems will eventually be overcome one by one.

What is AR?
- Superimpose the virtual world on the real world
The full name of AR technology is Augmented reality (augmented reality technology). AR technology was first proposed in 1990. Obviously, the concept of AR alone was proposed many years later than VR, and the technical difficulty of AR is indeed very great.

Augmented reality technology, as the name suggests, is a brand-new technology that "seamlessly" integrates the information of the real world and the information of the virtual world. To put it simply, it is to put the operating system of the virtual world on the real world and interact with it on one screen. For example: when the glasses we wear have AR technology, when we encounter something we don’t know, we can call up all the information of the object on our glasses, and we only need to keep the object in our glasses during the whole process. Within the sight range, and then achieve the purpose of obtaining information through specific operations, and the sight can still see other things without interfering with each other during the retrieval.

Then use a more professional language to explain the three prominent features of the AR system: first, the information integration of the real world and the virtual world; second, it has real-time interactivity; finally, it can be added in any space in our real world. virtual objects.

What is MR?
- Overlay the real world into the virtual world
The full name of MR is Mixed Reality (Mixed Reality). Superimposing things in the real world into the virtual world is not simply mixing the reality with the virtual. In the virtualization of the real world, the pictures captured by the camera are two-dimensional and have no three-dimensional effect. Therefore, it is necessary to use a computer to form a three-dimensional virtual image of the picture so that it can be well integrated into the virtual 3D world.

Will VR detonate MR faster than AR?
So back to the original question: Will VR greatly seize the market of AR in MR? The answer is: yes! And there is a clear trend.

Because the MR scene was very vertical in the past, many people were relatively vague about the concept of MR. At that time, the application of VR in the MR field was mainly mixed reality recording, that is, the combination of real people and VR games or scenes. Compared with the virtual interaction, it forms a stronger visual experience. A more advanced application is a virtual production method that is widely used in some TV programs and movie shooting.

The AR aspect is mainly represented by Hololens and magic leap on the glasses side and Apple ARKit on the mobile phone side. Through the environment tracking camera combined with SLAM 3D reconstruction, the virtual content is superimposed in the real world. With the expansion of the virtual content range, a combination of virtual and real is finally formed. Effect.

In fact, whether it is VR or AR, the previous MR has bugs and cannot be called real MR. For example, the mixed reality recording of VR is actually a real picture recorded by an external camera, and then combined with a computer or other equipment to provide calculations to "cut out" the characters in the scene, and finally achieve the effect of MR, but the problem is that this is not just for VR. Thanks to the device, after all, the screen seen by the device itself is still a VR screen, not an MR screen that combines real people and a large number of virtual screens. As for AR, let alone, due to technical problems, AR hardware has not realized MR in the true sense from beginning to end. All AR products on the market today can only show AR effects, no matter what AR device wants to achieve real MR. The MR effect must solve the problem of front and rear occlusion between the virtual screen and real people, which has extremely high requirements for AI computing and optical display.

So is there any way for VR and AR to realize MR?
The way to achieve MR in VR is to use a full-color perspective called Video See-Through (image perspective) technology to achieve the effect of MR. True front and rear occlusion relationships. However, there is no mature case of AR technology at present, so as far as who is closer to the standard of MR, it must be VR. Due to the relatively high technical difficulty of AR technology, it is understandable that it is weaker than VR in this respect.

Generally speaking, at this stage, VR will definitely detonate MR faster than AR at this stage. No matter in terms of overall experience, user base or even cost, VR is easier for people to accept than AR. MORE TECH INFOR :
