VentureBeat has an article about Tonchidot presenting their Sekai Camera at TechCrunch50 and it apparently has some kind of augmented reality annotation functionality on the iPhone. Looking at the video, it’s not clear if this is all Wizard of Oz or if they’re doing some kind of real localization and registration using features (like SIFT), tags (probably not), or positioning of some sort. My guess is that this isn’t really annotating the real world but I’d love for them to prove me wrong. Then maybe they’d go either further and use Blaine Bell’s view management algorithms to make it look nice.
