Nowadays, augmented reality (AR) has entered our lives. An AR tag is usually used and stacked on the products for sake of being detected and recognized easily. With the recognized pattern, AR system thereby can superimpose the corresponding virtual object on the AR tag. The AR tag, however, distort the perception of products. In this study, we proposed a method that the AR tag could be embedded on a digital screen by applying the technique of temporal psycho visual modulation (TPVM). The new method utilizes the differences between the human-eye perception and digital camera image-forming to stack an invisible AR tag on digital screen and projector. The AR tag can be detected by digital devices but not yet by human eyes. Based on this concept of AR and TPVM, the related applications would be achieved, such as the immersive virtual scene created in entertainment, commercial and entertainment.
