증강현실 인터랙션을 위한 QR Code의 변경 방법

Abstract

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 maychange 3D models or animations. Markers, by blocking designated regions, may be recognized as differentpatterns allowing for tangible user interactions. Unlike markers, it is difficult to alter QR code patterns becauseQR code contains error correction patterns. In most cases, altered patterns cannot be recognized. Our goal was toenable QR code based interactions for Augmented Reality games. By performing research and experiments, wediscovered 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 usingtransparent film overlays. We endowed tangible interaction capability to QR code for Augmented Reality games.
