What is VR? Virtual reality explained

Virtual reality, or VR, is the latest buzzword in the wonderful world of technology. Don’t be fooled into thinking it is a new technology though, it isn’t, but that’s not to say it isn’t something to get excited about.

For those who are wondering what on earth VR is and why you should be getting your knickers or pants in a twist over it, you’ve come to the right place.

We are about to tell you what virtual reality is, how it works and what devices there are currently out there using this wonderful technology that you should make it your business to know about.

First things first, you’re going to need to know what VR actually is. The clue is in the name – it’s the experience of a world that doesn’t actually exist. We aren’t talking about getting yourself lost in a book or daydreaming about a photo or painting however, even if these technically are also experiencing some sort of virtual reality.

The virtual reality we are talking about is one created by computers that allows you to experience and interact with a 3D world that isn’t real by putting on a head-mounted display and some form of input tracking. The display will typically be split between your eyes, creating a stereoscopic 3D effect with stereo sound, and together with the technology and the input tracking, it will create an immersive, believable experience, allowing you to explore the virtual world being generated by the computer.

VR will make you feel like you are there mentally and physically. You turn your head and the world turns with you so the illusion created by whatever world you are in is never lost.

Watch a film in the cinema and the split-second fear you might feel when a devastating earthquake happens on screen will very quickly disappear if you turn your head to see the person next to you munching away on their popcorn. Films and books take you to different fictional worlds, but they are not worlds you change based on your actions.
