After collecting all those photos on Google earth, integrated with location and GPS data, together with all the images they have in their search database – they mesh it ALL up together and tada!! Google Goggles!
Soon, you’ll be able to point an Android phone at someone and have his name pop out (together with his favourite food, lifestyle habits, and how many girlfriends he’s juggling – photos included)
That’s Google’s mission – to organize the world’s information.
I must say, this is amazing technology.
