New bar codes can talk to your cellphone

In their new incarnation, cellphones become a sort of digital remote control, as one CBS executive puts it. With a wave, the phone can read encoded information on everyday objects and translate that into videos, pictures or text files on its screen.

“The cellphone is the natural tool to combine the physical world with the digital world,” that executive, Cyriac Roeding, the head of mobile-phone applications for CBS, said the other day.

In Japan, McDonald’s customers can already point their cellphones at the wrapping on their hamburgers and get nutrition information on their screens. Users there can also point their phones at magazine ads to receive insurance quotes, and board airplanes using their phones rather than paper tickets. And film promoters can send their movie trailers from billboards.

Advertisers say they are interested in offering similar capabilities in the United States, but cellphones in the States do not come with the necessary software. For now, consumers have to download the technology themselves.

Still, big advertising and technology companies like Hewlett-Packard and the Publicis Groupe, an advertising conglomerate, are pushing to popularise the technology here.

Until now, in most parts of the world, Web surfing has been separate from everyday activities like riding the train, watching television and driving. But the new technology may erode that distinction.

“You’ve picked up this product, and you don’t want to go back to your PC,” said Tim Kindberg, a senior research at the Bristol, England, lab of Hewlett-Packard.

“Or you’re outside this building, and you want more information. We call it the ‘physical hyperlink.”

In much the same way that Web publishing took off because of the ability to link to other people’s sites, cellphone technologies linking everyday objects with the Web would reveal the digitally encoded attributes of tangible things on grocery shelves or newsstands.

There are other technologies being developed for consumers to scan objects, including radio waves, computer chips or satellite location systems, but the bar code technology is the most developed — and simple and cheap enough even for individuals to publish them on printed materials or on Web sites.
