Virtual reality is a computer generated simulation of a three-dimensional image or environment that can be interacted with in a seemingly real or physical way by a person using special electronic equipment. With this technology advancement, virtual worlds can be used as a representation of reality to practice many different things such as medical surgeries, class room lessons, video games and etc..
There are many pros to this technology, such as the improvement of gaming experience, virtual prototypes, training programs for military, medical training, psychological therapy, and many more. In the article by the Wall Street Journals, "Avatar II: The Hospital" shows that online simulations can teach the nurses to make what decisions to make during emergencies without really doing any harm in the real world. In another article by New York Times "No Budget, No Boundaries: It's the Real You" gives users the opportunity to live a lavish life to try on all kinds of designer clothing and go on lavish vacations. This gives them a feel of lavish living without spending much money to do the actual activities in real life.
However, there are also some cons to this virtual world. This includes that the virtual world cannot captures the real world because it is difficult and time consuming to recreate every little object of the real environment, and the users behavior can be impacted by virtual worlds. The article "Virtual world may impact real-world behavior" showed that with a research done to see the behaviors after participants randomly assigned to be a hero or a villain turned out that their behavior were affected by the role they played.
Virtual worlds can challenge its users to come up with creative thoughts and be tested in the virtual settings without doing harm to the real world if it did not work out. In a way it limited a lot of risks and helped coming up with creative ways to solve and test problems. I think the future of virtual worlds will be very useful to many people whether it is doctors, teachers, or gamer. It will be able to bring an incredible experience and be able to innovate creative ways to solve problems.
