If augmented reality (AR) is going to offer a reliable overlay for physical reality, it needs to be anchored into place.
In many cases, GPS positioning is employed to tether a Pokémon object or whatever to a particular physical spot. But GPS positioning can be off by several meters, and indoor reception makes it an iffy proposition for retailers.
Now, AR/computer vision firm Blippar is out with an indoor version of its urban visual positioning, offering what it says is a more reliable tether for AR than other indoor systems. The company, based in New York City and London, says it is the first to provide “an easy and end-to-end solution” to the problem of anchoring AR.
