Have you ever wanted to sing on stage with your favourite singer, or go to Mars? With virtual reality(虚拟现实), you might be able to do these without even leaving your home. Unlike real reality, virtual reality means completely imaginary(虚拟的) worlds, using high-performance computers, special glasses and gloves.
Virtual Reality (VR) has been with us for many years—at least as an idea. Although it’s hard to tell who is the father of this technology, history suggests that it could have been the fruit of not one but at least five key people with different inventions. Thanks to these inventors, the technology has now come into use. Virtual reality is an example of VR technology. It changes the way we communicate experiences in the same way the Internet has changed the way we communicate information.
Indeed, VR has become a worldwide reality, with different usages from computer games to medicine, engineering, scientific research, and so on. For example, medical learners are able to train through VR to deal with all kinds of injuries. Designers can check every corner of their buildings and make preparations. And if you are heading to Mars, a trip in VR can help you “see” what you will find before getting there.
One example was a doctor who practised an operation on a baby’s heart. With this he could plan out his operation ahead of time, and helped save the baby.
VR will make the world even smaller and of course it’s going to bring us closer together. However, virtual reality has some bad effects. The first big danger is disconnection from the real world. People may become less interested in their real lives. Besides this, too much use of VR equipment can create some physical and mental (精神的) dangers. Loss of one’s sense of direction and position, sea sickness and headaches are some signs of the illnesses after using VR equipments for long periods.
