According to Wikipedia, Augmented Reality is a term used for live direct or indirect view of a real-world physical environment whose elements are augmented (read: enhanced / given more information about graphically) using computer-generated imagery. It’s basically what you see when you look through the viewfinder on Iron Man or Samus Aran’s helmet. Apps like Layar, Google Sky Map (Android) and Wikitude World Browser (iPhone) already make use of this technology.
Well they say that there is an app for just about everything, and now there is one for even the iPhone itself. The “iPhone in iPhone” augmented reality app is basically a promotional app developed by Ogmento – a company which is currently focused on developing mobile augmented reality games and apps. The said company is home to popular augmented reality apps like ‘Put a spell’ and ‘Pengun books’ etc.
