Abstract

A system and method tracks the movements of a driver or passenger in a vehicle (ground, water, air, or other) and controls devices in accordance with position, motion, and/or body or hand gestures or movements. According to one embodiment, an operator or passenger uses the invention to control comfort or entertainment features such the heater, air conditioner, lights, mirror positions or the radio/CD player using hand gestures. An alternative embodiment facilitates the automatic adjustment of car seating restraints based on head position. Yet another embodiment is used to determine when to fire an airbag (and at what velocity or orientation) based on the position of a person in a vehicle seat. The invention may also be used to control systems outside of the vehicle. The on-board sensor system would be used to track the driver or passenger, but when the algorithms produce a command for a desired response, that response (or just position and gesture information) could be transmitted via various methods (wireless, light, whatever) to other systems outside the vehicle to control devices located outside the vehicle. For example, this would allow a person to use gestures inside the car to interact with a kiosk located outside of the car.

Claims

1. A method of controlling one or more vehicular-related devices, comprising the steps of:

sensing the position or motion of a driver or passenger of a vehicle; and

controlling a device associated with the operation, safety or comfort of the vehicle in accordance with the sensed position or motion.

2. The method of claim 1, wherein the motion includes a hand or body gesture.

3. The method of claim 1, wherein the device is associated with entertainment.

4. The method of claim 1, including the adjustment of car seating restraints based on head position.

5. The method of claim 1, including the deployment of an airbag based on the position, velocity or acceleration of a person in a vehicle seat.

6. The method of claim 5, further including the control of the velocity or orientation of the airbag based upon body position, velocity or acceleration.

7. The method of claim 1, further including the control of a device external to the vehicle.

8. A system for controlling one or more vehicular-related devices, comprising:

a device for sensing the position or motion of the head, body, or other body parts of a driver or passenger of a vehicle;

a tracking system for tracking the head, body, or other body parts;

a gesture/behavior recognition system for recognizing and identifying the person'"'"'s motions; and

a controller for controlling devices associated with the vehicle, whether under active or passive control by the vehicle occupant.

9. The system of claim 8, wherein the device for sensing is a video camera.

10. The system of claim 8, wherein the device is associated with entertainment.

11. The system of claim 8, including the adjustment of car seating restraints based on head position.

12. The system of claim 8, including the deployment of an airbag based on the position, velocity or acceleration of a person in a vehicle seat.

13. The system of claim 12, further including the control of the velocity or orientation of the airbag based upon body position, velocity or acceleration.

14. The system of claim 8, further including the control of a device external to the vehicle.
