Last week, Tokyo’s annual CEATEC show (Combined Exhibition of Advanced Technologies) was once again a showcase for some of the coolest mobile technology on Planet Earth. Today’s video round-up features audio QR, Fujitsu’s ‘UB Wall‘ - an ultra-high-tech, one-to-one customized video advertising display - and FP codes, and - not to be missed - NTT DoCoMo’s 3G mobile-based ‘Drunk Driver’ detector, apparently in high demand by bus companies and trucking firms.

WWJ thinks the FP codes (essentially, invisible barcodes) and audio QR technology stands a pretty good chance of fast adoption, given the masses of rabid advertising agencies out there trying to capitalize on the growing popularity of (a) camera phones that grab info via QR code and (b) digital broadcasting. An audio QR code is simply broadcast as metadata in a digital audio signal, such that the browser displays text, a clickable URL or other advertising message while you listen to a radio or tv program on a suitably enabled mobile phone. But for sheer outdoor-advertising-meets-mobile marketing genius, the UB Wall can’t be beat! (WWJ subscribers log in for more details and links.)

According to this article NEC has developed a system using a face recognition technology that determines the general attributes of a person standing in front of a digital display and outputs advertisements, according to their profile, to the persons FeliCa-enabled handset. NEC calls this system the “Digital Signage Solution,” combining their advertisement delivery and display system with their advertising value measurement system.

The new system can deliver advertisements in accordance with conditions such as geographical areas, time and attributes of target clients. And it can measure advertising effect, focusing on whether the people who saw the advertisement showed interest or whether the advertisement stimulated the viewers’ purchase activity, for example.

This seems to be a very cool build on the Fujitsu UB Wall concept. Looks like we’ll have to head-out to Odaiba and take a ride on that sometime in August!
