    The regular world presented to us by our five senses—you could call it reality 1.0—is not always the most user-friendly of places. We get lost in unfamiliar cities; we meet people whose language we don’t understand. So why not try the improved version: augmented reality (AR) or reality 2.0? AR technology adds computer-produced images (图像) on the real world via a mobile phone camera or special video glasses.

Early forms of AR are already here. With the right downloads, smart phones can deliver information about nearby ATMs and restaurants and other points of interest. But that’s just the beginning. A few years from now the quantity of information available will have increased hugely. You will not only see that there’s a Chinese restaurant on the next block, but you will be able to see the menu and read reviews of it.

This is where the next revolution in computing will take place: in the interface (界面) between the real world and the information brought to us via the Internet. Imagine bubbles floating before your eyes, filled with cool information about anything and everything that you see in front of you.

Let’s jump ahead to ten years from now. A person trying to fix their car won’t be reading a book with pictures; they will be wearing a device that projects animated 3-D computer graphics onto the equipment under repair, labelling parts and giving step-by-step guidance.

The window onto the AR world can be a smart phone or special video glasses. But in ten years’ time these will have been replaced by contact lenses (隐形眼镜) with tiny LEDs, which present something at a readable distance in front of the eye. So a deaf person wearing these lenses will be able to see what people are saying.

The question is, while we are all absorbed in our new augmented reality worlds, how will we be communicating with each other?
