The New Scientist reviews the current state of Augmented Reality and is a bit concerned:
“While some who back the technology think its time has now come, after more than a decade in development, others warn that undercooked applications or “apps” are set to disappoint users, potentially damaging the market.
The momentum building behind AR has been fuelled by the growing sophistication of cellphones. With the right software, devices like the iPhone can now overlay reviews of local services or navigation information onto scenes from the phone’s camera. [...]
Amid all the hype, however, there is a big problem: the sensors that the apps depend on are not always up to the job.”
