dottocomu, which does a terrific job of following the latest Japanese technology, reports that

NTT is planning an experiment into interactive advertising in the new Minato Mirai subway linking Tokyo’s Shibuya with Yokohama: it will have a system set up in a concourse tunnel that detects pedestrian movements via a brace of TV cameras and uses the information to alter the images (art, local information, and advertising) projected on the tunnel walls by eight high-spec projectors linked to PCs that are in turn fed by NTT’s VAAM content distribution server.

I can’t decide if this kind of tailored interactive ad regime is creepy or cool, or just both. I think I’ll have to experience it to decide.
