Japanese government backs out-of-home research
Japan’s Internal Affairs and Communications Ministry is committing about $1m to research mobile-phone interaction with digital signage.
Phone providers and electronics companies are expected to participate in trials of a service which will send promotional material such as discount coupons to handsets when their presence is detected by miniature base stations attached to digital-signage screens.
The tests this summer will be held at sites including Tokyo’s Akihabara

EXCLUSIVE: Is this the greenest OOH technology yet?

SmartBricks will turn walls into displays
New public buildings are increasingly designed with provision for screens – but what if the whole building could become a kind of display?

Also involved in the project, which participants hope will lead to a product by the end of this year, is Japanese construction firm 
Touchscreens reveal gallery’s hidden treasures
Visitors to the National Portrait Gallery at the Smithsonian Institution in Washington can now view previously inaccessible artworks through interactive kiosks.
