1, because most of the VR images are panoramic images shot by spherical cameras, with VR glasses, the scenery will change with the rotation of the head, just like the real world.

2. Most people divide VR glasses into three categories. The first category is the most common, and the mobile terminal display is commonly known as mobile phone VR. As the name implies, you need to connect your mobile phone when using it. The second is integrated VR, which has independent CPU, input, output and display functions. The third category is external VR, which needs to be connected to an external host.

3, mobile phone VR glasses operation is very simple. First, you need to download an APP with 3D movies on your mobile phone or the VR glasses you bought may have your own APP.

4. Then open the movie and install the mobile phone in a fixed position. Adjust the two wheels on VR glasses that can move back and forth to adjust the degree. Don't adjust them when you feel clearest. The middle wheel slides left and right to adjust, so that there is no ghost in the film.

5. The other two types of operations are actually similar, which are nothing more than built-in resources and external hosts. Generally speaking, VR glasses connected to an external host are more professional and effective, and there are certain requirements for the external host. For those who have never been exposed to VR technology before, VR glasses are undoubtedly a very magical thing. At the same time, of course, some people will be curious. What is the principle of VR glasses? Let us help you understand.

The principle of vr glasses

The main configuration of general VR glasses is two convex lenses. Because there is only one screen, the images seen by the left and right eyes must be separated independently to have stereoscopic vision. 3D stereoscopic glasses can imitate the real situation, make the left and right eyes display alternately on the screen continuously, and cooperate with the physiological characteristics of human vision to see what we call stereoscopic 3D images.

Simply put, the lens in VR virtual reality helmet is based on different visual fields, creating different depth perception in local space and forming virtual reality visual field in the user's brain visual system. The main limiting factor of virtual reality vision is the lens, not the pupil. In order to get a wider field of vision, it is necessary to shorten the distance between the user's eyeball and the lens or increase the size of the lens.

But it is worth noting that the size and weight of the helmet should be considered. Using a thinner lens will increase the distance between the lens and the display screen and the size of the head display will also increase. Using a thicker lens (the focal length of the magnified object is shorter) will shorten the distance from the display screen. However, the thickness of the lens will add new engineering challenges, because geometric distortion and chromatic aberration will occur. Because the picture is enlarged and enhanced, a higher definition display screen is needed to avoid the screen window effect (due to the lack of resolution of VR glasses at present, the human eye will directly see the pixels of the display screen, just like seeing something behind the screen window).

This paper takes VR glasses as an example for application.

How to use vr virtual glasses

Lead: With the development of digital technology, numbers have been integrated into us. Everyone should be familiar with vr virtual glasses. Some fans have got their own vr products, but many people find that they don't know how to use vr virtual glasses. Let's share with you how to use it. Interested friends can come and have a look.

How to use vr virtual glasses

How to use vr virtual glasses? We all know that VR(VirtualReality) is the abbreviation of virtual reality, and its specific connotation is a technology that comprehensively utilizes computer graphics system and various interface devices such as reality and control to provide immersive feeling in a computer-generated interactive three-dimensional environment.

So how to use vr virtual glasses? Generally speaking, VR devices can be divided into three categories: external headphones, integrated headphones and mobile terminal display devices.

External headphones have good user experience, independent screen, complex product structure and high technology content, but they are bound by data lines and cannot move freely.

One-piece headphones, less products, also known as VR all-in-one machine. You can enjoy the visual impact brought by 3D stereoscopic impression in the virtual world without any input and output devices.

The display device of the mobile terminal is simple in structure, low in price and convenient to use, and can be viewed as long as it is put into a mobile phone.

How to use vr virtual glasses? Take HTCVIves as an example. First, you have to find an activity space. When standing, you need a space of about 4.5m*4.5m, and make sure that there are no obstacles that can trip you.

And most importantly, you must ensure that there is no reflective equipment in your space, and of course, you should avoid sunlight.

When installing base stations, it is best not to let the distance between two base stations exceed 5 meters. After the installation is completed, you can start the computer and have a VR experience. It's simple to say, but it's still quite difficult to operate in practice.

The above is a brief introduction about how to use vr virtual glasses. There are many brands of vr virtual glasses, and the use methods of different products are slightly different. You can study and use them according to your own situation.

How to achieve the precise integration of VR glasses and motion capture positioning?

There are many ways to realize the precise integration of VR glasses and motion capture positioning, but they can be mainly divided into two categories: external positioning and internal positioning.

External positioning refers to the need to install multiple external devices in space, such as laser emitters, infrared emitters, cameras, etc. And determine the position and moving direction of VR glasses and hands through triangulation or visual tracking. The advantages of this method are high precision and low delay, but the disadvantages are high cost, complicated installation and limited space.

Internal positioning refers to the use of VR glasses' own sensors or cameras, independent of external devices, to achieve spatial positioning and gesture recognition in virtual scenes. The advantages of this method are low cost, simple installation and flexible space, but the disadvantages are low accuracy, long delay and easy interference.

How to use vr glasses:

You must find a moving space. When standing, you need a space of about 4.5m*4.5m to ensure that there are no obstacles to trip over. The most important thing is to ensure that there is no equipment that can reflect light in the space, and of course, avoid sunlight.

Download VR software with mobile phone and match VR glasses. After the installation is completed, you can start the computer and have a VR experience.

Precautions for using vr glasses:

1. If you are experiencing VR for the first time, I suggest you go to the VR experience store or find someone to accompany you. Because of VR, you can't see the surrounding environment of the real world. If you are too immersed in the virtual world, you will involuntarily do some actions and behaviors, such as walking around the room, or touching it with your hands, which makes it easy to trip, hit a wall, get an electric shock, or knock over something.

Remember not to expose it to the sun. The lens of VR glasses is actually a magnifying glass, which can focus, otherwise your mobile phone may smoke and spontaneously ignite inside.

Children under 3.3 years old cannot use it. Oculus and Samsung products have official statements, because children's heads are too small, which may affect children's vision development.
