Abstract: The practical areas of short distance optical wireless barcode technology can be improved manifold by the introduction of a temporally varying barcode method which can transfer large data files of any format. This method uses camera in smartphones as an alternative data channel. The data is encoded as a sequence of 2-D barcode images, displayed on a flat panel display, acquired by the camera, and decoded in real time by the software embedded in device. The decoded data is written to a file. The main advantage of such a scheme is that it does not require specifically developed hardware unlike other short range wireless technologies such as Bluetooth and Wi-Fi. Technical challenges to its implementation include correction of perspective distortion, compensation for contrast variation, and efficient implementation of small footprint software on handheld mobile devices. In this paper, we have developed a new data format for more efficient file transfer.
