Augmented reality (AR) seeks to produce a blended version of the real world and context-relevant virtual elements that enhance or augment the user’s experience in some way.  Since the term was coined back in the early 90s, AR has been a perennial disappointment, failing to live up to the original vision of immersive, spontaneous engagement with a blended virtual and real world.

GPS chipsets are getting smaller, cheaper, and more energy efficient. They are now ubiquitous in
smartphones and tablets, enabling a host of location-based services. But the
underlying positioning accuracy of consumer-grade GNSS receivers has stagnated
at approximately 2-3 meters. The next revolution in consumer-grade mobile
positioning will take us to centimeter accuracy, but will require some
clever tricks.
