Since a few years the internet in combination with mobile phone technology brought us something that we refer to as augmented reality: A digital projection that is placed over imagery of the existing environment to create a whole new world on the screen. Earlier this year Microsoft Bing-Maps architect Blaise Aguera y Arcas showed how augmented reality features can be added to digital world maps. Including streaming video. This means that when you switch to the streetview mode you get to watch live video streams, at least when someone is broadcasting there at that moment. It's also possible to see older footage that has been put in place with geographic photography techniques so ‘video time travel’ becomes an option. As many mobile devices already support photo and video, we can anticipate digital maps to become “live” within some years. This reminds us of the ultimate sonar system from ‘Batman: The Dark Knight’. And like the sonar system from the movie we can ponder on the ethical implications of a system that records half of the world. Will it add a whole new perspective or simply turn every camera phone into a potential security camera? The Big Augmented Reality Maps Brother is watching you!
