[Homework]2011-10-16&10-22 QR码
本帖最后由 Guzo 于 2011-10-20 15:38 编辑
You've probably bought groceries, and seeing the cashier scanning an item to get its price. It works because each product has a code, that's a shortcut, it prevents the cashier from having to look up each item. Well, these days, new kinds of codes are appearing that are scanable with camera phones, and like a cashier scaner, they creat shortcuts to all kinds of information. This is QR codes, explained by common craft. In our on-line world, everything is linked together,you visit a website, and click a link to visit another site, send a message, view a photo, or download a vedio, a simple click makes everything possiable. On the other hand, our physical world is what you see walking down the street, the problem is, nothing is clickable, you can't click a URL on a container to see recepiets, you can't click a statue to read it by a wikepedia, so you either type in the link, take notes, or just keep walking. But that starting to change, you may have seen codes like this, they are called QR, or quick response codes, and they mean your camera phone can now be a little like a cashier scaner. Once you have a QR reader APP on your smart phone, you can point your camera phone at this codes and immediately grap useful information. Let say running airions and walk by a sign that says new show coming soon, and there's QR code, you can just open your QR reader APP, point your camera phone at the code, and the APP will automatically give you options. No links to remember, no notes, just point your phone at the QR code and the real world becomes clickable, but that just a begining. Imagine visiting a landmark, and using a QR code to watch a vedio about it, or scaning a QR code in a newspaper or magazine to email a link to a friend, or scanning one to follow your local bakery on twiter, QR codes are important because for the first time, they make the real world clickable.
