Abstract

A method and system are presented for restricting the use of a portable electronic device by a driver who is operating a vehicle. A body area network (BAN) signal is sent from a vehicle device in the vehicle in close proximity to the driver. The BAN signal is transmitted using the driver'"'"'s biological body as a signal transmission path. The portable electronic device includes a receiver configured to detect the BAN signal when the device is in close proximity to the driver. The portable electronic device is further configured to disable or restrict at least one function in response to detection of the BAN signal, thereby preventing or restricting use of the portable electronic device when the driver is seated in and operating the vehicle.

Claims

1. A method for restricting the use of a portable electronic device, the method comprising:

transmitting a signal configured to be transmissible over a body area network (BAN) using a vehicle device;

receiving the signal at the portable electronic device through a receiver in the device, the receiver receiving the signal after transmission through the BAN; and

carrying out an action responsive to the received signal.

2. The method of claim 1 wherein the body BAN comprises a biological medium as a signal transmission path.

3. The method of claim 2, wherein the BAN comprises transmission of the signal as a capacitive signal.

4. The method of claim 2 wherein the biological medium is a human in the position of a driver of the vehicle.

5. The method of claim 2 wherein the biological medium is a human in the position of a passenger of the vehicle.

6. The method of claim 4, wherein the signal is a driver restricted mode signal.

7. The method of claim 5, wherein the signal is a passenger restricted mode signal.

8. The method of claim 7, wherein the passenger restricted mode signal disables camera functionality on the portable electronic device.

9. The method of claim 1, wherein carrying out an action stores the signal on the portable electronic device.

10. The method of claim 1, wherein carrying out an action issues an alert on the portable electronic device indicating that the portable electronic device will be entering a restricted mode.

11. The method of claim 1, wherein carrying out an action restricts functionality of the portable electronic device.

12. The method of claim 11, wherein restricting functionality includes disabling at least one communication-related function of the portable electronic device.

13. The method of claim 12, wherein restricting functionality locks out communication functions of the portable electronic device except for emergency service communications.

14. The method of claim 1, wherein the transmitting occurs in response to determining that the vehicle is operating.

15. The method of claim 14, wherein determining that the vehicle is operating comprises receiving a signal indicative of vehicle operation.

16. The method of claim 15, wherein the signal indicative of vehicle operation is a signal indicating that the vehicle is in gear.

17. A system for restricting the use of a portable electronic device in a vehicle, comprising:

a vehicle device within the vehicle, configured to transmit a body area network (BAN) signal, the vehicle device including

a BAN electrode mounted in the vehicle in a location having close proximity to a driver the driver is operating the vehicle; and

a controller connected to the BAN electrode and configured to generate and transmit the BAN signal through the BAN electrode.

18. The system of claim 17 wherein the vehicle device is configured to generate an electric field generated by applying voltage to the electrode.

19. The system of claim 17, wherein the signal is a warning signal to indicate that the portable electronic device will be entering a restricted mode.

20. The system of claim 17 wherein the signal is a timing signal.

21. The system of claim 17 wherein the signal is a passenger-restricted mode signal.

22. The system of claim 17 wherein the signal is a driver-restricted mode signal.

23. A portable electronic device comprising:

a processor;

a receiver, connected to the processor, and configured to receive a body area network (BAN) signal via a body area network;

a driver lock-out module having computer-executable instructions which, when executed, configure the processor to;

detect receipt of the BAN signal at the receiver and,

in response to detection of receipt of the BAN signal, disable at least one function of the portable electronic device.

24. The portable electronic device of claim 23, further comprising a phone application, and wherein the driver lock-out module includes instructions that configure the processor to restrict the phone application to hands-free operation when the BAN signal is detected.

25. The portable electronic device of claim 23, wherein the driver lock-out module configures the processor to disable at least one communication function in response to detection of the BAN signal.

26. The portable electronic device of claim 23, further comprising a device casing, and wherein the receiver includes an electrode having at least a portion exposed through an aperture in the device casing.

27. A vehicle device for restricting the use of a portable electronic device in a vehicle, comprising:

a BAN electrode mounted in the vehicle in a location having close proximity to a biological medium; and

a controller connected to the BAN electrode and configured to generate and transmit a BAN signal through the BAN electrode.

28. The vehicle device of claim 27, configured to generate an electric field generated by applying voltage to the electrode.

29. The vehicle device of claim 27, further comprising a BAN transceiver.

30. A method for restricting the use of a portable electronic device, the method comprising:

receiving, at a vehicle device, an indication that the vehicle is in operation; and

in response to receiving the indication, transmitting a signal configured to be transmissible over a body area network (BAN) using the vehicle device to the portable electronic device.

31. The method of claim 30 wherein the body BAN comprises a biological medium as a signal transmission path.

32. The method of claim 31, wherein the BAN comprises transmission of the signal as a capacitive signal.

33. The method of claim 32 wherein the biological medium is a human in the position of a driver of the vehicle.
