There are many types of interactive posters that have been introduced over the past few years, but a team from the University of Washington is now introducing a new kind of smart posters.
'FM Backscatter' introduces smart posters that are able to communicate directly with car radios and smartphones using background FM radio signals with a technique that's known as "backscattering." To tune into these posters, people must be within a certain range before they can pick up on the frequency.
Potential applications for these smart posters include band or festival posters that share snippets of songs, billboards that share additional information on local attractions or even street signs that broadcast the names of intersections to improve accessibility for people with disabilities.
