A virtual reality (or VR) headset is a device that you wear over your eyes like a pair of goggles. It blocks out all external light and shows you an image on high-definition screens in front of your eyes. The goal of the VR headset is to immerse you in a game. In VR games, your point of view is your character’s point of view; most VR headsets track your head movement, so that wherever you look, your character looks, too. If done well, you’ll feel like you are inside the game.
These VR headsets are not game consoles on their own. They must be connected by a cable to a gaming system like PlayStation 4 for Sony’s Morpheus.
Oculus Rift, Microsoft’s Hololens, HTC VIVE, Samsung Gear VR are the famous VR headsets and also Google cardboard. Google Cardboard is container type made up of plain cardboard and it fully relies on smartphone hardware.
