Scientists develop system that can shut down your phone while you're driving

Researchers have discovered how to stop drivers using their phones when they are behind the wheel without affecting use for passengers.
A team at Stevens Institute of Technology and Rutgers in New Jersey have created a system which shuts down a driver's phone without affecting other people in the vehicle.
It utilises a phone's Bluetooth connection and a vehicle's speakers to detect if the driver is using their mobile phone while driving, reports CNET.
The system measures the acoustic signals emitted from the stereo and the proximity of the phone to the Bluetooth receiver, essentially pinging both systems to determine where the phone is being operated.

By measuring the phone's distance between the speakers, the phone can estimate its distance from the car's centre, and determine more than 95 percent of the time if the phone is in the possession of the driver or a passenger.

Once the ownership is determined, the phone can decide if it needs to lock down services, according to CNET.

Using a vehicle's existing Bluetooth and audio technology, researchers have figured out how to block smartphone use by people behind the wheel

The system created by a team led by doctors Chen Stevens, Marco Gruteser and Richard Martinis is designed to allow passengers to use their phones while the vehicle is in motion.
However, problems to overcome include the amount of road, wind and background noise interfering with the acoustic signals and a general lack of Bluetooth connectivity in most vehicles.
Current anti-distracted driving technology uses an app that runs in memory and uses the phone's GPS to figure out if a user is in a vehicle or not.
But this means that if a mobile phone user is in a bus, taxi, or passenger seat, the phone shuts down, and its effectiveness also depends on the phone's signal strength.
