An example of VR technology
Have you ever wanted to sing on stage with Taylor Swift, or go to Mars? With the rise of virtual reality (虚拟现实), you might be able to do these things without even leaving your home. Unlike real reality, virtual reality means completely imaginary worlds, using high-performance computers and 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 the father of this amazing technology, history suggests that it could have been the fruit of not one but five key people. First, Morton Heilig introduced users to 3D films. Then, there’s Jaron Lanier, the first person to use the term “Visual Reality”. Douglas Engelbart invented the computer mouse. Ivan Sutherland is the inventor of the first HMD and Myron Krueger, the audio wiz. Thanks to these inventors, the technology has now come of age. Users can virtually experience things they could only dream of. Virtual reality is changing 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 types of applications ( 应 用 ) from computer games to medicine, engineering, scientific research, and so on. For example, medical learners are able to train through VR in order 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 virtual reality can help you “see” what you will find before you get there.
One recent example was a doctor who practiced an operation on a little baby’s heart. This enabled him to plan out his surgery ahead of time, and helped to save the baby.
VR will make the world even smaller than it is now. It’s definitely going to bring us closer together. Like any technology, however, virtual reality has its negative effects. The first big danger is disconnection from the real world. Apart from this, too much use of VR equipment can create obvious physical and even mental (精神的) dangers. Loss of one’s sense of direction and position, sea sickness and headaches are among the signs of illness some experience after using virtual-reality equipment for long periods.
