Google’s getting a lot of attention for their new Google Mobile App for the iPhone, mainly because of the spectacularly effective voice recognition system that lets users search the Web, location-based info and contact info internal to the iphone by voice.

What we’ve found to be most interesting is the fact that Google is using sensors built into the iPhone, specifically the accelerometer and the proximity sensor that usually turns off the keypad when the phone’s next to someone’s face, to make this operation a handsfree and button free experience.

The user simply picks up the iphone, holds it next to their face and then speaks the command — not even a spoken annunciation (”computer, beam us up…”) is required. Just another example of how motion apps are changing the way we interact with our devices.

BTW… in case you wondered why other developers haven’t come out with apps that behave this way… well there is some controversy about how Google got access to these APIs
