Demo: A Barcode Streaming System for Smartphones

摘要

As a potential alternative for radio frequency (RF) technology, visible light communication (VLC) has received significant attention recently. In contrast to RF technologies, VLC can enable secure and interference-free wireless links due to the directional and short-range natures of visible light. We demonstrate COBRA [1], a special form of VL-C for off-the-shelf smartphone systems, which can be potentially used in scenarios like contactless mobile advertisement/payment (e.g.. in retail stores and museums) and data exchange between smartphones.
