We've mentioned the tantalizing possibilities of augmented reality here several times, including Microsoft's stab (using scene recognition)
as an information overlay for cell phones, and some display technologies that could make a Terminator-style information overlay on the real world possible without even looking down at a screen, including both glasses with microdisplays
and contact lenses
. An anonymous reader points to this two-part review
of several cell phone apps
, in which the writer has "tested several mobile augmented reality browsers and their ability to find places to eat and function as a tourist guide by identifying tourist attractions in London," writing, "This is the first review I have seen where all the browsers have been compared together; what's interesting is all the browsers use different data sources, and so either miss popular locations or give the wrong location."
