The whole point of VR is to immerse yourself in a new world. However, other than the VR headset, there are also many other parts necessary for VR to actually work. VR headsets like Playstation VR and Oculus Rift are called head mounted displays, which means that the screen is mounted to your face. Wherever you move your head, the screen follows you.
For certain VR headsets like the HTC Vive and the Oculus Rift, a console or computer is needed for the headsets to work. Video is sent from the console or the computer to the VR headset. For other headsets like the Google Daydream and the Samsung Gear VR, a smartphone has to be slotted into the headset, and the video plays from the phone.
VR headsets either use two LCD displays (one per eye) or two feeds sent to one display. Headsets also have lenses placed between your eyes and the screen, which are used to focus and reshape the picture for each eye. They create a stereoscopic 3D image by angling the two 2D images. This is because the lenses mimic how each of our two eyes see the world very slightly differently.
VR headsets also need to have a minimum frame rate of at least 60 frames per second in order for the user to not feel sick. Current VR headsets are able to go way beyond this, with Oculus and the HTC Vive at 90 frames per second and PlayStation VR at 120 frames per second.
