9 to 5 Mac
Have we reached the point where Augmented reality has gone mainstream? Perhaps. Today Trip Advisor rolled out their iPhone/iPod touch upgrade (free, iTunes) with the included feature. After playing with this for a matter of minutes I can tell that this is going to be big.
Sure other apps like Layar have been doing this for awhile but Trip Advisor is probably the most mainstream app so far to incorporate augmented reality.
The App uses the compass and your GPS to figure out where you are and what you are looking at. Trip Advisor has a huge database of Hotels, Restaurants and things to do listed by geo-location and shows you which way to head to find them.
Also, there is nothing to do in my home town.
