Project Tango: Google is building it, but will they come?

Google's Project Tango allows mobile devices to gain awareness of the space around us. Could the technology be as game-changing as the iPhone was, or is it just another shot at the moon?

In early 2014, Google made an interesting announcement. The company had a new product in the pipeline, one that could change the way we interact with computers. Google showed a prototype of the technology built into a Nexus phone. Dubbed Project Tango, it allowed the device to gain awareness of the space it was in, and to do so far more precisely than anything seen previously.

Google pre-announced the technology, it seems, because it didn't really know what to do with it.
