Virtual Reality is Changing the World part2 Besides games, VR has already filtered to every aspect of people’s life and has great effects. At first, the VR system was applied for pilots training. Using VR training instead of actual training, not only saves a lot of costs of money, but also avoids injuries and deaths of pilots. Especially during simulated air combats, VR system avoids tons of destruction of buildings and equipments. In school, take astronomy courses for example, students could put their headsets on and see the grand universe and get specific conception of Galaxy and so on. In future-which I suppose not far from now, we could enjoy a fantastic world with VRs. No matter how far between couples, they could see each other face to face using VR. People could travel around the world without long-time airplanes or trains travelling, without being pushed by crowds. Even for some busy people who work all day and don’t have enough time for travelling to far places, they could see the splendid scenery at home. And this only costs them several minutes as long as they put their VR headsets on. People may argue that virtual reality is not reality and what we see is not real via VR. They point it out that VR can easily cause addiction. Some children and even adults may indulge in VR games and VR travelling and so on. This may trigger a phenomenon that few and few people attend real activities. Also they hold a view that indoor VR communications maybe convenient, but it will make people find reality less interesting. They would rather talk to the doppelgangers of people in VR than in reality. When new technology comes out, it always bring benefits but also trigger troubles to the society. Just like a coin has two sides. We can’t focus only on the benefits or the troubles it brought. What we need to do is trying to strengthen the benefits and also preventing as possible as we can from the problems it triggers. Since VR is changing our world, we must prepare as much as we can.
