Disney researchers have demonstrated that light bulbs can do more that just illuminate our rooms – they could communicate with each other, with objects and with the Internet, to create ‘smart’ environments.
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.
Stefan Mangold, who heads Disney Research’s wireless research group, said these advances could give Visible Light Communication (VLC) an important role in the growing Internet of Things – the idea that objects can communicate with each other and share information to create smart environments.
