VR or virtual reality is a way in which, with the use of a head set, a person can be transported to an entirely different world, one that can see, hear and interact with.
Headsets like Google Cardboard work by holding your phone in front of your eyes. Two little lenses use the screen to make it seem like what is on your phone is right in front of your eyes.
Without the lenses your phone screen looks like this.
Sensors in your phone then detect your head movements and move the content on the screen in relation to it. This way you can turn your head and see something else to the side of you.
Better VR headsets like the Vive work instead with external sensors which track the movement of the headset within a predetermined space. The Vive also give the user the ability to use their hands to pick up and interact with the virtual reality through two handsets.
VR can be used for games, to really take the player to the next level in immersion. It can also be used in art exhibits to show the 'player' what life is like in someone elses shoes.
AR or augmented reality is different. Instead of taking the user into a completely new space, it uses the real world and adds virtual content over the top of it.
Here we have an example of AR that I filmed. Nintendo have included AR games within their handheld consoles ever since they've had a camera on them. In this game, the aim is to shoot little flying heads that are slowly destroying your world.
AR can also be used in the every day, for example an app that fits furniture into your living space using your phone's camera. This way the buyer can see if the product they want to buy fits into the space.
