VR, short for virtual reality, allows people to be fully immersed in a fabricated environment. This is usually (but not always) delivered through head-mounted hardware that tracks a person’s movements. These VR headsets consist of a screen (or two display panels, one for each eye) housed in a frame (or headset) strapped or fitted to your head. A pair of lenses are typically fixed between the panels and your eyes, blocking the outside world, to make it appear as if what you see through the headset is your entire world. Critically, all headsets track your movement so the image you see adjusts accordingly. Some headsets, however, track more movement than others. In most cases, VR experiences will also have a method for you to control or select things within the simulated environment. Sometimes you’ll have a controller in each hand to control aspects of the experience. In some cases, the controllers deliver virtual representations of your hands to manipulate the environment and objects within it in ways similar to the real world.
