According to the Merriam-Webster Dictionary online, virtual reality is, “an artificial world that consists of images and sounds created by a computer and that is affected by the actions of a person who is experiencing it.” It is most easily described as a life online. One of the most common uses virtual realities are games. Skyrim is an example of virtual reality game. Many games have the gamer create an avatar, or character, that moves through the virtual game. Virtual reality also is used for educational purposes. Some universities created virtual reality classrooms and have courses on how to create virtual reality games.
A way to view a virtual reality is with the oculus rift. The oculus rift is headwear that shows you some sort of world in 3D, and moves the camera to wherever your head points. This is mostly used for gaming. However, it also can be used for simulations. Oculus Rift is used in driving simulations to teach people how to drive cars. It is used to teach future airline pilots how to fly planes. One advantage of these kinds of simulations is that if there is a problem no one actually gets hurt while learning to drive or fly.
Another use for virtual reality is entertainment. Any animated TV show or movie can be considered to be virtual reality. The movie, Avatar, used virtual reality in the plot to allow the characters to experience another world without physically being there. “On Ice” is another movie that uses virtual reality and special glasses to see the pictures stand out. Smart televisions have been developed that allow people to experience television shows in 3D virtual reality using special glasses to see the images.
