The light that typically floods homes, offices and public buildings could provide something more than illumination. Scientists at Disney Research and ETH Zurich have demonstrated that light could be a medium for light bulbs to communicate - with each other, with objects and with the Internet.
Transmitting signals via light is nothing new; Alexander Graham Bell showed that speech could be conveyed with light in the 1880s, years before speech was first transmitted via radio. The Disney researchers, however, have created networking technology that makes it possible for LED lights not only to communicate with each other, but to do so in a way that is compatible with the Internet and its technical protocols.
