What are VR glasses? What are VR glasses for?

The role of VR glasses is to guide users to feel in a virtual environment.

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.

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.

Extended data:

The principle of VR glasses is similar to human eyes. Two lenses are equivalent to eyes, but far less intelligent 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 are often not in a straight line, which makes the visual effect very poor and leads to many problems such as unclear and deformation.

In an ideal state, the center of the pupil, the center of the lens and the center of the screen should be in a straight line. At this time, it is necessary to adjust the pupil distance of the lens to coincide with the pupil 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 SVR Glass needs software to adjust the pupil distance.
