Macworld has an article about a new offering from Metaio that excites me: image-basd augmented reality. The whole idea of augmented reality is so cool: point your phone's camera at something, and when you view the live image on your iPhone you'll see related information or content superimposed on that image. Think of how useful this would be to tourists: you point your phone at the Eiffel Tower, and your phone superimposes information about it. Augmented reality has already been available, but it was GPS-based. Now for the first time Apple has opened up its camera application interface so that developers can have access to the video stream. They can create apps that actually recognize the image on the screen in order to give you related content. Imagine going to a museum or art gallery and having your iPhone recognize what you're looking at, and then giving you more info. Metaio has just launched tools that will allow developers to take advantage of this new opportunity. The possibilities are endless. They also have a free app in the App Store, junaio, an augmented reality browser. Read more about it on the junaio website.
