What are VR glasses? What's the use? How to use it?

1. What are VR glasses?

VR glasses are VR headsets, virtual reality head-mounted display devices. Since there was no concept of head-mounted display in the early days, unprofessional names such as VR glasses, VR goggles, and VR helmets were given based on the appearance. 2. What are the uses of VR glasses?

VR headsets use head-mounted display devices to close people's vision and hearing to the outside world, guiding users to have a feeling of being in a virtual environment. The display principle is that the left and right eye screens display images for the left and right eyes respectively. After the human eye obtains this differential information, it creates a three-dimensional sense in the mind.

VR glasses are a product that uses simulation technology, computer graphics, human-computer interface technology, multimedia technology, sensing technology, network technology and other technologies. It is a brand-new human being created with the help of computers and the latest sensor technology. Computer interaction means not only allow every enthusiast to experience it with surprise and joy, but also become deeply fascinated by the unknown of its birth and prospects. 3. How to use VR glasses:

Many cheaper VR glasses on the market require the help of a mobile phone. Put a 4.7-5.7-inch mobile phone into the VR glasses and download the corresponding APP on the mobile phone. (Different brands have their own mobile software) and you can use it.

There are various VR software in major mobile application stores. I use "Orange VR". There are many other softwares. I will not list them here. However, the methods of using mobile phones and VR glasses are similar. . The details are as follows:

1. Find the switch and turn on the VR glasses (the position of the power-on button of different brands of VR glasses is different, please refer to the instructions of the VR glasses for details)

2. Use your mobile phone to download VR software , usually requires 2 necessary steps.

The first is to pair VR software with VR glasses.

The second is to set the screen size of the mobile phone so that the screen size matches the VR glasses.

3. After the mobile VR software is set up, click on the game or 3D environment you want to experience, and the mobile phone screen will be split left and right.

4. Insert the mobile phone into the VR glasses. Different glasses have different insertion methods. 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.

Introduction to the principle of VR glasses

The principle of VR glasses is similar to our eyes. The two lenses are equivalent to eyes, but they are far from human eyes. Eye "intelligence". In addition, VR glasses generally split the screen and cut the content in half, and achieve superimposed imaging through the lenses. At this time, the center of the pupil of the human eye, the center of the lens, and the center of the screen (after split screen) are not in a straight line, resulting in poor visual effects, unclearness, deformation, and many other problems. [3]?

The ideal state is that the center of the pupil of the human eye, the center of the lens, and the center of the screen (after split screen) should be on a straight line (as shown below). In this case, you need to adjust the lens The "pupillary distance" is made to coincide with the pupil distance of the human eye, and then the software is used to adjust the center of the picture to ensure 3 points and a line, so as to obtain the best visual effect. Some domestic devices are adjusted physically, and some are adjusted through software. For example, the interpupillary distance of Baofeng Magic Mirror needs to be adjusted through the knob above, while SVR Glass requires software to adjust the interpupillary distance.
