Previous augmented-reality (AR) applications have required users to observe the integration of real and virtual images on a display. This study proposes a novel concept regarding AR applications. By integrating AR techniques with marker identification, virtual-image output, imaging, and image-interaction processes, this study rendered virtual images that can interact with predefined markers in a real three-dimensional (3D) environment.
