Falling asleep while driving? There's an app for that

Under most circumstance, smartphones are a distraction to drivers, but Adelmann and Jablonski have figured out how to turn a nuisance into a digital copilot. Drivers download the app, which is still under development, then mount their mobile device on their dashboard or place it in a cup holder while they drive. The program then uses features already built into most smartphones – accelerometer, gyroscope, GPS and video camera – to alert drivers if they appear to be dozing off and give them feedback on their driving.
