adidas goes AR

Adidas has launched a line of sneakers that allow you to use it as a game controller. And the promo videos are not to miss. The shoes have a QR ("Quick Response") code printed on the tongue that enables your webcam to see how you're holding your shoe. Adidas is very much employing new technology as a branding feature here, as I don't see a whole lot of practical uses in holding your shoe -especially when it's all old and smelly- in front of your pc. But some interesting apps that encourage people to get more physical with their pc may pop up. How about playing first-person soccer with your own feet, personal dance lessons with direct feedback, or a virtual running coach that sees how you run?
