Unsynchronized 4D Barcodes Coding and Decoding Time-Multiplexed 2D Colorcodes

Abstract

We present a novel technique for optical data transfer between public displays and mobile devices based on unsynchronized 4D barcodes. We assume that no direct (electromagnetic or other) connection between the devices can exist. Time-multiplexed, 2D color barcodes are displayed on screens and recorded with camera equipped mobile phones. This allows to… (More)
