Abstract(ENG)

QR code has been widely used for Augmented Reality games as well as for many commercial applications. However, its usage was limited because it is difficult to enable tangible interactions through which users may change 3D models or animations. Markers, by blocking designated regions, may be recognized as different patterns allowing for tangible user interactions. Unlike markers, it is difficult to alter QR code patterns because QR code contains error correction patterns. In most cases, altered patterns cannot be recognized. Our goal was to enable QR code based interactions for Augmented Reality games. By performing research and experiments, we discovered a mechanism for altering QR code to change the text string that the QR code represents. In this paper, we introduced a QR code alteration prototype that is based on composition of partial QR codes by using transparent film overlays. We endowed tangible interaction capability to QR code for Augmented Reality games.
