MP3 players could get GPS system

Looks like even MP3 players are no longer exempt from the GPS craze if computer scientists have their way. This brainchild involves an MP3 player that comes with an integrated GPS navigation system, enabling users to be directed to their destination while listening to songs. Assuming you’re headed towards the right direction, you get stereo audio. Should you need to change directions, the volume will shift to different ears. This is a neat way of being directed without having to refer to a display at all times, making you look less vulnerable while walking especially if you’re new in a particular city.
