QR (Quick Response) Codes are widely used as a convenient unidirectional communication channel to convey information, such as emails, hyperlinks, or phone numbers, from publicity materials to mobile devices. But the QR Code is not visually appealing and takes up valuable space of publicity materials. In this paper, we propose a new method to embed QR Code on digital screen via temporal psychovisual modulation (TPVM). By exploiting the difference between human eyes and semiconductor imaging sensors in temporal convolution of optical signals, we make QR Code perceptually transparent to human but detectable for mobile devices. Based on the idea of invisible QR Code, many applications can be implemented, e.g., \"physical hyperlink\" for something interesting on TV or digital signage , \"invisible watermark\" for anti-piracy in theater. A prototype system introduced in this paper serves as a proof-of-concept of the invisible QR Code and can be improved in future works. |
