1. What are VR glasses?
VR glasses are VR head-mounted displays and virtual reality head-mounted display devices. Because there was no concept of head-up display in the early days, unprofessional names such as VR glasses, VR goggles and VR helmet were produced according to their appearance.
Second, what is the use of VR glasses?
VR head display is to use head-mounted display equipment to close people's vision and hearing to the outside world and guide users to feel in a virtual environment. Its display principle is that the left and right eye screens display the images of the left and right eyes respectively, and the human eye will have a stereoscopic impression in its mind after obtaining these different information.
VR glasses are products that combine simulation technology, computer graphics, man-machine interface technology, multimedia technology, sensor technology, network technology and so on. It is a brand-new means of human-computer interaction created with the help of computers and the latest sensor technology, which not only surprises every amateur, but also fascinated by its birth and prospect.
Third, the use of VR eyes:
Many cheaper VR glasses on the market need the help of mobile phones. Put a 4.7-5.7-inch mobile phone into VR glasses, download the corresponding APP in the mobile phone (according to different brands, you have your own mobile phone software) and you can use it.
There are all kinds of VR software in all major application malls of mobile phones. I use "orange VR" and many other softwares. I won't list them here, but the method of combining mobile phones with VR glasses is similar. Details are as follows:
1. Find the switch and turn on the VR glasses (different brands of VR glasses have different power-on keys, please refer to the instruction manual of VR glasses for details).
2. It usually takes two necessary steps to download VR software with a mobile phone.
The first is to pair VR software with VR glasses.
The second is to set the screen size of the mobile phone to make the screen size conform to VR glasses.
3. After the VR software of the mobile phone is set, the screen of the mobile phone will split left and right after clicking the game or 3D environment you need to experience.
4. Insert the phone into VR glasses. Different cups are placed in different ways. After putting it in, you need to align the center line of the left and right split-screen videos with the center line of the glasses.

Brief introduction to the principle of VR glasses
The principle of VR glasses is similar to our eyes. Two lenses are equivalent to eyes, but far less "smart" than human eyes. In addition, VR glasses generally divide the content into two screens, cut them in half, and achieve superimposed imaging through lenses. At this time, the center of the pupil, the center of the lens and the center of the screen (after split screen) are often not in a straight line, which makes the visual effect very poor and leads to many problems such as unclear and deformation. [3]
In an ideal state, the eye pupil center, lens center and screen center (after split screen) should be in a straight line (as shown in the following figure). At this time, it is necessary to adjust the "pupillary distance" of the lens to coincide with the pupillary distance of the human eye, and then adjust the center of the picture with software to ensure 3 points 1 line, so as to obtain the best visual effect. Some domestic devices are adjusted by physics or software, such as Storm Mirror, whose pupil distance needs to be adjusted by the knob above, and SVRGlass needs software to adjust the pupil distance.

VR Glasses _ Baidu Encyclopedia Name and function of each part of VR glasses: Head display device is a kind of hardware device that closes people's vision and hearing to the outside world and guides users to feel in a virtual environment. Host system refers to the equipment that provides various functional guarantees for HMD. We generally divide a complete VR system into four parts: head-mounted display device, host system, tracking system and controller.
Advantages of VR glasses
VR glasses can be used to watch videos. For example, wearing these glasses to watch a movie feels like sitting in a big cinema and watching a movie alone. In addition, the VR puzzle card can realize the realization of three-dimensional two-dimensional, zero-distance contact with two-dimensional, break through AR, enhance VR, and make 3D virtual more realistic. The interactive function of folding fan card can realize the arbitrary conversion of various postures through finger operation.
VR can be divided into three categories: external headphones, integrated headphones and mobile terminal display devices. Put a monitor on people's eyes, and wherever people look, they will show the scenery in the corresponding direction, thus making people feel that they are in an infinite virtual space.
Does htcvive have to install a locator?
For example, Dapeng E3 positioning version is needed, and the dual base stations adopt Polaris binocular laser positioning system, which realizes 360 mm positioning surround and multi-directional laser cross scanning, with wider range, stronger anti-interference ability, reduced number of sensors on helmet and handle, light and portable, and is very suitable for playing VR games. So playing VR games requires a locator.

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.
Mobile terminal display devices, such as VRbox, have simple structure and low price, and are easy to use as long as they are put into mobile phones.
The world's first VR glasses with folding design are smaller and lighter, which effectively saves space and weight and is easy to carry. It is also suitable for mobile phones with 4.5 to 6-inch screens.
