We have been familiar with 3G mobile phone and 3­D TV. Now let's experience RealCine - virtual reality film, which will amaze you. RealCine works by making the users feel that they are really in a new world. To achieve this, special VR headsets are designed to allow the users to see in 3­D and hear the sound all around them. Toadd to the virtual world of RealCine, the headsets even have small openings that give out smells to match the environment. Both the headsets and the special gloves are connected to a computer network in the VR studio.In scientific studies it has been shown that VR can be a good treatment for people who have social problems. Besides this, VR can be used to practise skills in a secure environment that otherwise would be quite dangerous. Finally, RealCine provides fantastic technology for urban planning.

　　Although an argument has been put forward that some users will be disappointed by RealCine because VR is not real, with VR we are able to do things that could never be achieved in real life.
