N Building is a commercial structure located near Tachikawa station amidst a shopping district. The team at Qosmo working together with teradadesign architecture studio thought of using QR Code (two-dimensional bar code) as the facade of the building. By reading the QR Code with your mobile device you can obtain up to date shop information but the fun doesn't end there. Using the iPhone with specially developed application you can see what is happening inside the building with people's comments made on online appearing in speech bubbles. You can also browse shop information, make reservations and download coupons (see video).
