VR stands for virtual reality. A VR headset refers to a device worn on the head to provide the wearer with a simulation experience. Virtual reality technology aims to create an almost natural 3D virtual environment, which tricks our brain into accepting it as our new reality. The headset utilizes LCD screen technology to project stereoscopic 3D images from 2D images. The headset can give you the illusion that you are in another world/dimension just by wearing it.
