增强现实和虚拟现实有什么不同？

科技可以改变你看待这个世界的方式。
增强现实和虚拟现实是科技可以改变你看待世界的两种方式。这个术语可能令人迷惑。有时候人们认为AR和VR是相同的东西。
增强现实和虚拟现实越来越多的应用在科技中，因此知道他们的不同是重要的。
这个图片帮助我们解释了这两者的不同。
增强现实
增强现实被定义为，是通过使用科技为一些东西的图片上增加数字信息而创造出来的，现实的增强版本。
AR用于智能手机和平板电脑的应用程序中。AR应用程序使用你的相机在你面前为你展示一个真实的世界场景，然后在这个场景上添加一个信息图层，包括文本和/或者图片。
应用程序能使用AR用于娱乐，例如游戏宠物精灵，或者用于信息，例如Layar应用。
使用增强现实，Layar能展示关于你去的地方的一些有趣信息。当你正在参观某个地方时打开Layar，它会在你眼前为你显示一个信息图层。
使用Layar你也能发现自动取款机、看到拍卖的房地产，发现餐馆，和更多有用的AR特性。你甚至可以发现你从来不知道的新地方。
这个视频为你展示了如何通过在Layar应用上增强现实的工作原理。
这个应用在谷歌商店的安卓版本、苹果应用商店的手机和平板应用是免费的。
虚拟现实
虚拟现实定义为，使用计算机科技创造一个模拟环境。
当你查看VR时，你将看到一个和你面前完全不同的现实场景。
虚拟现实可能是人造的，例如一个动画场景，或者一个已被拍照的真实地方并且被放入一个虚拟现实app。
在虚拟现实中，你可以来回移动并查看每一个方位--上，下，侧身和后边，就像你真的在那儿一样。
你可以通过一个特殊的VR设备看虚拟现实场景，例如一个虚拟现实头戴式显示器。其它虚拟现实使用在你的手机和VR应用，例如谷歌Cardboard和Daydream平台。
在虚拟现实应用中，你可以探索从未去过的地方，例如火星表面，珠峰顶部，或者海洋深处。纽约时报有一个可以让你在地球和其他星球体验虚拟环境的应用。
谷歌地球也有一个虚拟现实应用。
查看这个视频看它是如何工作的。

Augmented Reality vs. Virtual Reality – What’s the Difference?

Tech(nology) can change the way you look at the world.

Augmented reality and virtual reality are two of the ways that tech can change the way you look at the world. The terms can be confusing. Sometimes people think AR and VR are the same thing.

Augmented reality and virtual reality are increasingly used in technology, so knowing the difference is important.

This picture helps explain the difference between the two.
Augmented Reality
Augmented reality is defined as "an enhanced version of reality created by the use of technology to add digital information on an image of something."
AR is used in apps for smartphones and tablets. AR apps use your phone's camera to show you a view of the real world in front of you, then put a layer of information, including text and/or images, on top of that view.
Apps can use AR for fun, such as the game Pokémon GO, or for information, such as the app Layar.
The Layar app can show you interesting information about places you visit, using augmented reality. Open the app when you are visiting a site and read information that appears in a layer over your view.
You can also find money machines, see real estate for sale, find restaurants, and more using the AR feature of the app. You may even discover new sites you did not know existed.
This video shows you how augmented reality works with the Layar app.

Layar is available free for Android on Google Play and iPhone and iPad at the iTunes App Store.
Virtual Reality
Virtual Reality is defined as "the use of computer technology to create a simulated environment."
When you view VR, you are viewing a completely different reality than the one in front of you.
Virtual reality may be artificial, such as an animated scene, or an actual place that has been photographed and included in a virtual reality app.
With virtual reality, you can move around and look in every direction -- up, down, sideways and behind you, as if you were physically there.
You can view virtual reality through a special VR viewer, such as the Oculus Rift. Other virtual reality viewers use your phone and VR apps, such as Google Cardboard or Daydream View.
With virtual reality apps, you can explore places you have never been, such as the surface of Mars, the top of Mt. Everest, or areas deep under the sea. The New York Times has a virtual reality app that lets you experience virtual environments on Earth and other planets.
Google Earth also has a virtual reality app.
