A new technology might change the way people watch movies in the theater. Instead of watching a film on the screen, you would enter the scene and watch the action take place all around you. This is what Virtual Reality, or VR, and 360-degree video promise to give audiences. The idea is to make you feel like you are in the movie. Online websites like YouTube and Vimeo already offer some VR films. Both professionals and amateurs have made these kinds of films. To watch, people wear expensive headsets that cover their eyes and ears. There are less costly ways to see VR films. Many people use their smart phones, placed in a special cardboard box. Then, they hold it up to their eyes to watch. The boxes can be bought from Google for $15. People are experiencing the technology in many places.
