Abstract

A method for enhancing driver safety through body position monitoring with remote sensors, and furnishing feedback in response to vehicle motion, driver activities, and external driving conditions, wherein the method includes: monitoring and characterizing signals from at least one sensor mounted on the body of a driver; monitoring and characterizing signals from at least one vehicle mounted sensor; determining driver activity based on disambiguating the signals from the driver and vehicle mounted sensors; providing feedback to the driver based on the determined driver activity, vehicle motion, and external driving conditions; and wherein the feedback is employed to modify driver behavior and enhance driver safety.

Claims

1. A method for enhancing driver safety through body part position monitoring with remote sensors, and furnishing feedback in response to vehicle motion, driver activities, and external driving conditions, wherein the method comprises:

monitoring signals from at least one sensor mounted on a body part of a driver;

monitoring signals from at least one vehicle mounted sensor;

determining driver activity based on the signals from the driver and vehicle mounted sensors; and

providing feedback to the driver based on the determined driver activity, vehicle motion, and external driving conditions.

2. The method of claim 1, wherein:

the determining of driver activity is based on correlating accelerometer data from a sensor mounted on a upper limb of the driver with corresponding driver steering wheel control actions.

3. The method of claim 1, wherein:

the providing of feedback to the driver is vibro-tactile feedback having a specified pattern and duration; and

wherein the provided feedback alerts the driver without the knowledge of passengers in the vehicle.

4. The method of claim 3, wherein:

the duration of the vibro-tactile feedback is based on a stress level that the driver is experiencing as a result of the driving activity, vehicle motion, and external driving conditions.

5. The method of claim 3, wherein:

the duration of the vibro-tactile feedback is about 3 seconds based on a high stress level activity.

6. The method of claim 3, wherein:

the pattern of the vibro-tactile feedback is based on a stress level that the driver is experiencing as a result of the driving activity, vehicle motion, and external driving conditions.

7. The method of claim 1, wherein:

the providing of feedback to the driver is directly applied to the part of the driver'"'"'s body requiring behavior modification.

8. The method of claim 1, wherein:

the providing of vibro-tactile feedback to the driver is through a wrist mounted device.

9. A system for enhancing driver safety through body part position monitoring with remote sensors, and furnishing feedback in response to vehicle motion, driver activities, and external driving conditions, the system comprising:

a network of sensors including at least one sensor mounted on a body part of the driver, and at least one vehicle mounted sensor;

a computing device in electrical signal communication with a network of sensors;

wherein the computing device is configured to execute electronic software that manages the network of sensors;

wherein the electronic software is resident on a storage medium in signal communication with the computing device; and

wherein the electronic software determines driver activity based on the signals from the driver and vehicle mounted sensors, and provides feedback to the driver based on the determined driver activity, vehicle motion, and external driving conditions; and

wherein the feedback is employed to modify driver behavior and enhance driver safety.

10. The system of claim 9, wherein:

the determining of driver activity is based on correlating accelerometer data from the sensor mounted on an upper limb of the driver with corresponding driver steeling wheel control actions.

11. The system of claim 9, wherein:

the providing of feedback to the driver is vibro-tactile feedback having a specified pattern and duration.

12. The system of claim 11, wherein:

the duration of the vibro-tactile feedback is based on a stress level that the driver is experiencing as a result of the driving activity, vehicle motion, and external driving conditions; and

wherein the duration of the vibro-tactile feedback is inversely proportional to the stress level.

13. The system of claim 11, wherein:

the pattern of the vibro-tactile feedback is based on a stress level that the driver is experiencing as a result of the driving activity, vehicle motion, and external driving conditions.

14. The system of claim 9, wherein:

the vehicle mounted sensors are embedded in a steering wheel; and

wherein the embedded sensors within the steering wheel further comprise;

pressure sensitive switches; and

wherein the pressure sensitive switches can detect when the driver has their hands on the wheel, or if the drivers hands are in a non-optimal position.

15. The system of claim 9, wherein:

the providing of feedback to the driver is directly applied to the past of the driver'"'"'s body requiring behavior modification.

16. The system of claim 9, wherein:

the providing of vibro-tactile feedback to the driver is through a wrist mounted device.

17. The system of claim 9, wherein:

the sensor is mounted on the upper limb of a driver and employs Radio Frequency Identification (RFID) tags and readers embedded in a vehicle'"'"'s steering wheel to determine the proximity of the drivers hands to the vehicle'"'"'s steering wheel.

18. The system of claim 9, wherein:

the sensor is mounted on the tipper limb of a driver and employs Bluetooth transmission and receivers embedded in a vehicle'"'"'s steering wheel to determine the proximity of the driver'"'"'s hands to the vehicle'"'"'s steeling wheel.

19. An article comprising machine-readable storage media containing instructions that when executed by a processor enable the processor to manage a system for enhancing driver safety through body part position and vehicle monitoring with remote sensors in electrical communication with a computing device, and furnishing feedback in response to vehicle motion, driver activities, and external driving conditions, wherein the instructions comprise:
