When people look at the world around them, the images are slightly different due to the different positions of the two eyes. The images merge in their minds to form an overall picture of the surrounding world, which includes the information of distance . Of course, the distance information can also be obtained by other methods, such as the distance of the eye focal length, the object size comparison.
In the VR system, binocular stereo vision plays a big role. Different images seen by the user's two eyes are generated separately and displayed on different displays. Some systems use a single monitor, but users with special glasses, one eye can only see odd frame images, the other eye can only see even frame images, odd and even difference between frames is the disparity Produced a sense of three-dimensional.
