Augmented reality (AR) is a technique to let we compose the real and the virtual world. As for the AR technology, various application is enabled. Particularly, AR is expected for the application to business very much. Moreover, AR applications can complement a standard curriculum. Text, graphics, video and audio can be superimposed into the real time environment of students. Therefore the AR technology can be also expected for the application to the education. In this paper, we focus on the educational application, and we try to visualize the design by the AR technology. The algorithm is implemented by using the Visual C++ 2008 and C on a personal computer.
