Nike in Japan and agencies Wieden + Kennedy Tokyo and ROOT Communications want you to make faces and embarrass yourself in front of your webcam. The brand created a fun web application to communicate the product attributes of its new Free shoe, an incredibly flexible shoe that you can squeeze with your hands and now, thanks to the app, with your face. The app combines facial recognition technology and expression recognition technology to let users bend, twist and control the Nike sneaker using your facial expressions. The app calculates facial flexibility from the eyebrow to the chin, in order to define the diagonal movement of the shoe, and the symmetry of the mouth to define the horizontal movement of the shoe. In addition, the application recognizes the color of the user’s clothes and the background to automatically coordinate the color of the shoe using the NIKEiD customization system. Pretty cool.
