We present 'Screen codes' -a space-and time-efficient, aesthetically compelling method for transferring data from a display to a camera-equipped mobile device. Screen codes encode data as a grid of luminosity fluctuations within an arbitrary image, displayed on the video screen and decoded on a mobile device. These 'twinkling' images are a form of 'visual hyperlink', by which users can move dynamically generated content to and from their mobile devices. They help bridge the 'content divide' between mobile and fixed computing.
Collomosse et al. proposed "Screen codes" REF for transferring data from a display to a camera-equipped mobile device, where the data are encoded as a grid of luminosity fluctuation within an arbitrary image.
