Car key that prevents mobile use while driving
Researchers at the University of Utah have come up with an automobile ignition key that prevents teenagers from talking on mobiles or sending text messages while driving. The invention is called Key2SafeDriving and aimed at cutting down on road deaths. It relies on Bluetooth technology to wirelessly connect keys to phones.
The system includes a device that encloses a car key - one for each teen in the family. The device connects .wirelessly with each key user's mobile via either Bluetooth or RFID (radio-frequency identification) technologies.
To turn on the engine, the driver must either slide the key out or push a button to release it. Then the device sends a signal to the driver's mobile, placing it in 'driving mode' and dis¬playing a 'stop' sign on the phone's screen. While in driving mode, teen driv¬ers cannot use their mobiles to talk or send text messages, except for calling 911 or other numbers pre-approved by the parents. Incoming calls and texts are-automatically answered with a message saying, "1 am driving now. I will call you later when I arrive at the destination safely."
