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.

通过手机,人们可以看到前往目的地餐馆的路线,能看到周围自己感兴趣的数据。抬头看天空也能利用增强现实技术读取到星星的名字、飞过的国际航班和他们的目的地。这样的对信息的接触,人们正在适应。类似Wikitude、Blipar这样的应用在国内也能找到,像“这儿”这样的基于地理信息的增强现实应用,像“美梦成真”这样的把身份证图像、钞票图像,甚至交通卡图像通过手机识别后转换为趣味动画的应用等等。

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

这样的电视开始的时候,电视的生产和传播也将发生变化。传统的电视台原来只需要传递声画信息,而现在则要提供更多的、个性化的,基于地理信息或其它大数据的信息给特定的观众,想想就是个巨大的工程。而人们需要沉浸在信息空间的巨大要求,使得这样的不可能完成的任务变成可能,变成人们不断创新的目标。

增强现实和虚拟现实有什么不同?

电视在进入了3D4K的时代后,人类仍然在继续改进电视。8K电视已经出现,可是我们的追求方向只是清晰度的不断提升吗?从平面到立体电视,人类已经做了很多工作,未来还将实现不戴眼镜的裸眼3D。未来电视还将怎样演进?在欧美,已经开始了Augmented TV的研发工作,也有一些产品正在问世。

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 andiPhone 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.
Check out this video to see how it works.
