Augmented Reality (AR) applications launch on the iPhone.
While I have spent years getting excited by the possibilities of mobile apps like semapedia, (unlike most of my clients, who dispite my best efforts, passed on the opportunities). Now with the launch of a raft of genuine AR apps Like this from DiscoverAnywhere there appears to be a real case for commercial use. While it is true the actual audience of iPhone & Android users is really small compared with total universe of mobile (cell) phones, in time this should be the standard for 'whats that?' questions in the street. The answer being you aim your phone at the object and heh presto the phone overlays a label telling price, location, availability or simply its name.
Very interesting that Amazons tech division A9 have brought Snaptell, which basically puts Amazons prices and availability information over the top of any item you see in a shop, (currently only works in the US)
Like most people I often emerge from a station and ponder where is? (the nearest bar) having an interactive live map to overlay reality is a fantastic bit of black magic to delight. This last bit, is in my opinion, the key to any new techs ability to succeed, is it a joy to use and do you want to tell you mates about it?
Just look at the footage below of the yelp.com trial AR feature, yes you really do have to shake the phone three times for it to show the hidden button, how charming is that? -there is also a neat London Bus AR demo HERE from Presselite. The Next Web has a bit about a live tweeter layer which could see even more tourists actually being hit by buses (while tweeting), the guys at Presslite had us tracking.
