What is the market prospect of VR/AR panoramic view?

VR technology has begun to erupt, the development prospects are bright, and the road is very twisted. VR is the abbreviation of virtual reality technology. It is an emerging technology that has just developed in the past two years. It can be said that the VR market prospects are very good. As a composite technology, it integrates core technologies such as sensors, data visualization, graphic images, and human -machine interaction. It is currently widely used in entertainment, film and television, tourism and other fields.

Recent statistics, the entire VR industry is growing year by year. In 2019, the VR market size is estimated to be about $ 6.2 billion, and it may reach the expected $ 16.3 billion worldwide by 2022. VR is an important area that plays an important role in many industries such as entertainment, training, education and medical care. However, although VR technology has huge potential and has been used in some scenarios, there are still technical problems that hinder their potential.

The good news is that many people think that the biggest obstacle of VR can be overcome by 5G, low delay, ultra -fast speed and stable head display connection, which will make the VR experience easier to access, more reliable, and more importantly. The situation.

What is VR?

VR is virtual reality, and it is also called spiritual realm and fantasy.

The definition of VR: Use a computer to simulate a virtual world that produces a three -dimensional space, providing users' simulation of sensory such as visual, hearing, touch, etc., so that users can observe in real time and unrestricted to observe the three -degree space in real time. Things, and interact with it. The sentence is a bit long. We simply say: It is to create a completely virtual environment through specialized glasses to make you reciprocal.

Why do you say he hi? Let's take a look at the dynamic drawing below:

Does it look like a mental attack? They are playing VR. Some people say, 'Isn't VR just 3D?' Obviously, this understanding is wrong. Compared with the traditional 3D, VR is much stronger: the perspective range of human eyes is usually 120 degrees from the perspective under a fixed perspective. Cinema screens are generally within this range. In this range, the image cannot be seen. To put it plainly, the perspective of 3D movies is fixed. The VR realizes the 720 -degree panoramic 3D immersion view. 720 degrees panorama, that is, on the basis of 360 degrees, the range of vertical 360 degrees is increased, and the panorama of 'sky' and 'earth' can be seen.

In this way, with the gyroscope sensor of the VR helmet, when your head is rotated, the screen you can see will be switched simultaneously, which is the so -called 'immersion'. In addition, VR can achieve interaction through gesture control or tactile feedback (3D movies can only be one -way).

What are the VR devices?

At present, there are not many types of VR equipment on the market. The more common HTC VIVE:

What is AR?

Speaking of VR, what is AR? AR is Augmented Reality.

Through computer technology, it applies virtual information to the real world. The real environment and virtual objects are superimposed in real time to the same screen or space at the same time. For AR, the most famous is that Magic Leap in 2015, the big whale of the global basketball court:

Of course, there is also a popular phenomenon -level mobile game Pokemon GO in 2016:

Simply put, AR is the combination of virtual and reality. On the basis of reality, it increases auxiliary virtual images. Google's Google Glass is an AR device.

The difference between VR and AR

VR and AR are actually very easy to distinguish.

Virtual reality (VR), the scenes and characters you see are all 'fake' (the image is generated by the device, and shows you). The image allows your consciousness to substitute into a virtual world.

Augmented reality (AR), part of the scenes and characters are true, part of which is 'fake', to bring virtual information into the real world.

VR is a pure virtual scenario, so VR equipment is more used for interaction between users and virtual scenes. More use is: location tracker, data gloves, motion catching systems, data helmets, and so on.

VR/AR

AR is a combination of real scenes and virtual scenes, so basically requires cameras. Based on the screen of the camera, it is combined with the virtual screen to display and interact.

It is the most intuitive to distinguish the appearance of the device.

The R device is relatively 'bulky' and needs to be covered on the head like a helmet; fully closed, there are rubber or sponge products with the facial contact area to close the face and equipment to prevent light leakage; eye lens is usually a round convex lens.

The AR device is relatively 'lightweight'. For example, Google Glass, the eye lens is usually a square prism. After the user wears AR glasses, the image is projected on the prism through the miniature projector in the frame, and then reflects near the eyes through the prism. Display content above the real scene.

The application of VR and AR

VR and AR, which emphasize immersive experience, are the first applications, of course, game entertainment. Compared to the black and white machines, small bully, arcade, and PC games we played before, this 'movement' game method is obviously a cool technical subversion. In addition to games, this method also brings low -cost, high -efficiency innovation to training. For example, flying, medical care, of course, the application of military is also indispensable:

The vast number of Diaosi is definitely interested in the following application. Essence Essence Alas, the Earth people can no longer stop the 'action love' industry of the island country. All in all, the application field of VR/AR is very broad, and these years have indeed attracted a lot of investment, and the development is extremely rapid.
