Wikitude gives you real time information about the display of your cell phone when you're pointing it at something. This is possible because the GPS knows where you are. Anyone who spots an interesting castle, for example, will be shown when it was built.

The media-evolution is becoming more and more clear. We can ask questions with everything we see. Just to whom? The traveling guide may be able to tell you everything about the history of your environment, but a brand that knows everything about nature might know exactly what you can eat and what you can’t, or which animals live there and are threatened with extinction. And yet other types of brands can tell you what you’d like to do around there. No one brand knows everything about you, know your interests in every area like the back of your hand. This is how multiple brands are created, multiple coaching brands, brands we can ask questions. This is a very clear step in that direction.
