Google has developed a device similar to a Star Trek: The Next Generation Communicator. It is a wearable prototype pin with a built-in Mic and bluetooth to connects to a smartphone. It allows one to surf Google without having to dig out your phone.
The Star Trek like Google pin is in the testing phase. Google continues to push the limits with their voice search feature. The voice feature could also access other apps on their android phones.
