Quickly, the picture comes alive with hyperlinks (超链接), offering the names of the buildings, towers and street features that appear in the photo. The hyperlinks lead to information about the history, services and context of all the features in the photo. You have just hyperlinked your reality.

That might be a little unbelievable, but the technology exists and is no fevered imagination. This is not a cool small machine invented for the next James Bond movie; this is a working technology just developed by European researchers. It could be coming to a phone near you, and soon.

This, as the marketing types say, is a game changer. It develops a completely new interface (界面) that combines web-technology with the real world. It is big and fresh, but it goes much further and has much greater influence.

The development of the system is most outstanding because image recognition technology has long been pregnant with promise, but seemed to suffer from an unending labour.

Now MOBVIS has not only developed image recognition; it has also developed more applications for the technology; and it has adapted it to the world’s most popular technology: the mobile phone.

The MOBVIS system completely rewrites the rules for exploration and interaction with your physical environment. The system begins with panoramas (一连串景象). These panoramas form the basis of a city database. It can match buildings, towers, banners and even logos that appear in the panoramas.

A user simply takes a picture of the street feature, MOBVIS compares the user’s photograph to the panoramas and then identifies the buildings from the picture you take and the relevant links are returned.

Then you simply click on the links, using a touch-screen phone, and the MOBVIS system will provide information on the history, art, architecture or even the menu, if it is a restaurant, of the building in question.
