Navigation
A big use and continued potential for Augmented Reality is navigation. City guides
such as Yelp and NRU (pronounced “near you”) which help people find places to eat,
drink, and shop have Augmented Reality capabilities that give users real-time visual
directions to the places their looking for.
Another application called TapNav uses AR to overlay your route on the road
ahead (Figure 1.18). The visual benefits to this are immediately obvious as you can
quickly see where you are supposed to be going with easy visual cues. However,
there are currently a couple of drawbacks with this concept as well. Most significantly
is the danger associated with looking through a mobile phone while driving.
