“Many people enter the inside-out world of augmented reality (AR) by doing something as ordinary as visiting a major city like New York and trying to get to a local friend’s favorite pizza shop, somewhere deep in Brooklyn, via public transportation. Standing in Times Square on a summer evening, they might hold up a new smart phone and pan it slowly around the Square to see a pointer to the nearest subway entrance overlaid on their phone’s video display of the buildings around them.” (Joe Lamantia – UXmatters)
