Working principle of virtual reality glasses

Virtual reality glasses all work on the principle of 3D side by side . That means dividing the screen into 2 frames, each eye responding to an image frame. When you wear glasses, those two frames will be focused through the lens, helping the image to condense and create a 3D model-like buoyancy.

Screens projecting images will usually be very close to the eye 10 – 15 cm . But when you put on glasses, you see the image far away, like watching a movie projected on a screen that is hundreds of inches in size.

In order to have interaction between users with the virtual reality simulation environment, the display screens can be smartphones, televisions, etc., helping to process information as soon as you turn right, left or look up. , down.
