Don't act too surprised if, some time in the next year, you meet someone who explains that their business card isn't just a card; it's an augmented reality business card. You can see a collection and, at visualcard.me, you can even design your own, by adding a special marker to your card, which, once put in front of a webcam linked to the internet, will show not only your contact details but also a video or sound clip. Or pretty much anything you want.
It's not just business cards. London Fashion Week has tried them out too: little symbols that look like barcodes printed onto shirts, which, when viewed through a webcam, come to life. Benetton is using augmented reality for a campaign that kicked off last month, in which it is trying to find models from among the general population.
Augmented reality – AR, as it has quickly become known – has only recently become a phrase that trips easily off technologists' lips; yet we've been seeing versions of it for quite some time. The idea is straightforward enough: take a real-life scene, or (better) a video of a scene, and add some sort of explanatory data to it so that you can better understand what's going on, or who the people in the scene are, or how to get to where you want to go.
