Extended reading Susan, an industry leading tech magazine editor, is interviewing Frank, an expert in virtual reality. They are read the interview transcript below virtual reality. Frank, you've been . working at the forefront of developments in virtual reality for many years. Can you tell us what virtual reality is and how IT works? Of course, the basic definition of VR lies in the name itself, which means reality that is not real. When you wear AVR headset, a quick with sensors and a screen, you are surrounded by three d images, sounds and other sensory information, which creates a super realistic tic effect called presence. Though, you know, the sensory information surrounding you is not real, part of your brain believes that is, and act accordingly. Thanks, Frank. Can you give some examples of the practical applications V. R has? I'd love to, there are a host of educational applications. Academic VR, enable students to interact with others in a3d environment。There are endless possibilities for the subject matter that can be created in AVR system. Imagine studying the solar system or the human body in a fully immersive environment by delivering the content in a meaningful way. This new approach to learning managers to engage students interest and enhance learning efficiency. The applications can be expanded to make IT easier to visualize data, such as engineering projects and a variety of other design developments. It's pretty exciting. This sounds like IT has a lot of constructive applications. What about its uses? For highly developed technical industries such . as medicine? Surgeons are already using robotic technology with to perform complex surgery. What if I told you that doctors could create a virtual twin in order to practice delicate surgery before attempting IT on the patient? This technology can be applied to train new surgeons. IT also enables experts to test new techniques safely before trying them on human subjects. Treatments of anxiety and drug addiction are rather valuable in cost effective applications of V, R. That is amazing. IT sounds like V, R will be a life changing technology as well as a life saving one. How will IT affect the different aspects of our everyday lives, such as entertainment, shopping and traveling? The entertainment industry is one of the most enthusiastic advocates of V, R. Current game systems come with headsets so that players can enter virtual environments and play against either real or virtual opponents. IT won't be long before virtual museums and interact 3d exhibitions become common。When shopping online, you can look forward to being able to have your own virtual reality clone try on clothes and to see products with three hundred and sixty degree views. Also people who want to go on holiday, we will have the opportunity to take a virtual tour of several destinations before deciding where to go. In both of these cases, this technology will help people make more informed choices. I can't wait. However, as with any technology, there must be some barriers to the development of V. R. I guess IT . really boils down to three things, time cost. In technical limitations, we will need time to develop and fine to the hardware and software. The initial cost will discourage most people in the beginning, but that should be fixed over time. The last issue is our own technical limitations. Just trying to figure out how to do what we want in terms of technology will prove chAllenging in some areas. considering there are so many chAllenges to deal with, are you still optimistic about the future of VR? sure. When talking about V, R, we should keep in mind its quick rate of evolution. The possibilities seem endless. For example, 5g technology，with its potential to serve up more stable mobile connectivity yet faster speed, will make IT possible for people to enjoy a more immersion VR experience wherever they are. Indeed, we are only limited by our imagination. What excites me the most is that Young people today are digital citizens who are comfortable with technology. They are well equipped to become part of a technological generation that will develop and use VR to do things we might think impossible today. Thank you, Frank IT all sounds wonderful.
