2. A feeding device as set forth in claim 1 wherein said sensor includes a facial recognition sensor.

3. A feeding device as set forth in claim 2 wherein said facial recognition sensor is a camera.

4. A feeding device as set forth in claim 2 wherein said facial recognition sensor is a two-dimensional camera; and

a distance sensor.

5. A feeding device as set forth in claim 1 including a distance sensor.

6. A feeding device set forth in claim 1 wherein said sensor is attached to the feeding device.

7. A feeding device as set forth in claim 1 including:

a processor receiving an input from said sensor; said processor generating an output including relative positional information of the individual's mouth; and

a control unit receiving information as to the relative positional information and generating a control signal directing the feed arm assembly to position the food approximate the individual's mouth.

8. A feeding device is set forth in claim 1 wherein said sensor includes a camera operative to capture an image of the individual's face and a processor connected to said camera and operative to analyze said image and generate positional information of the individual's mouth; and

a controller connected to said processor and operative to control said feed arm based on said positional information.

9. A feeding device as set forth in claim 1 including:

a processor receiving an input from said sensor based on said perceived characteristic and generating an output based on said perceived characteristic;

a control unit receiving said output from said processor and generating a control signal operative to direct the feeding device to perform a function associated with said perceived characteristic.

10. A method of transferring food to an individual comprising:

providing a feed arm assembly;

providing a sensor, using said sensor to perceive a characteristic associated with an individual;

generating a signal corresponding to the characteristic;

operating said feed arm based on said signal;

providing a camera, using said camera to capture an image of the individual;

analyzing the image and generating an output signal based on said image;

using a distance sensor to determine a distance to the individual;

using said output signal and said distance to generate an approximate location of the individual's mouth.

11. A method as set forth in claim 10 including the steps of using a camera to obtain an image of an individual's face;

using a facial recognition algorithm to determine a location of the individual's mouth;

using a distance sensor to determine a distance to the individuals face;

generating an output signal corresponding to a position of the individual's mouth and transmitting said output signal to a controller; and

using said controller to operate said feed arm to position the food approximate the individual's mouth.

12. A method of transferring food to an individual comprising:

providing a feed arm assembly;

providing a sensor, using said sensor to perceive a characteristic associated with an individual;

generating a signal corresponding to the characteristic;

operating said feed arm based on said signal;

using a camera to obtain an image of an individual's face;

using a facial recognition algorithm to determine a location of the individual's mouth;

generating an output signal corresponding to a position of the individual's mouth and transmitting said output signal to a controller; and

using said controller to operate said feed arm to position the food approximate the individual's mouth.

13. A method as set forth in claim 12 wherein said characteristic associated with the individual includes a predetermined movement of the individual; and

associating a particular operation of the feed arm with the predetermined movement of the individual.

14. A method of using a feeding device for transferring the food to an individual for consumption comprising:

providing a facial recognition sensor, using said sensor to perceive a characteristic of the individual's face;

analyzing said characteristic to determine position of the individual's mouth; and

generating an output signal corresponding to the position of the individual's mouth and transmitting said output signal to a controller; and

operating a feed arm to transfer food to the individual using said output signal.

15. A method as set forth in claim 14 wherein the step of providing a facial recognition sensor includes using a camera to obtain an image of the individual's face.

16. A method as set forth in claim 14 wherein the step of providing a facial recognition sensor includes using a camera to obtain a 3-D image of the individual's face and using the 3-D image to determine three-dimensional coordinates of the individual's mouth.

17. A method as set forth in claim 14 including the step of associating a predetermined physical movement of the individual with a particular operation of the feed arm; and

monitoring the individual for the predetermined physical movement.
