Abstract

A system for recognizing various human and creature motion gaits and behaviors is presented. These behaviors are defined as combinations of “gestures” identified on various parts of a body in motion. For example, the leg gestures generated when a person runs are different than when a person walks. The system described here can identify such differences and categorize these behaviors. Gestures, as previously defined, are motions generated by humans, animals, or machines. Multiple gestures on a body (or bodies) are recognized simultaneously and used in determining behaviors. If multiple bodies are tracked by the system, then overall formations and behaviors (such as military goals) can be determined.

Claims

1. A method of controlling a device without touching it, comprising the steps of:

sensing human motion using an electromechanical process;

outputting descriptive data including position and velocity information associated with the sensed motion;

determining if the motion is a recognizable gesture based upon the descriptive data; and

if the motion represents a recognizable gesture, generating a command to control the apparatus in accordance with the recognized gesture.

2. The method of claim 1, wherein the electromechanical process uses an electrogoniometer or electrogoniometric system.

3. The method of claim 1, wherein the electromechanical process uses passive reflective or actively illuminated markers to calculate positions or velocities.

4. The method of claim 1, wherein the electromechanical process uses force data gathered from a force plate or force dynamometer.

5. The method of claim 1, wherein the electromechanical process uses strain gauge or piezoelectronic transducers.

6. The method of claim 1, including the step of classifying the gesture as a static gesture if the slowness of the motion falls below a predetermined threshold.

7. The method of claim 1, wherein the device is a virtual-reality simulator or game.

8. The method of claim 1, wherein the device is a self-service machine.

9. The method of claim 1, wherein the device forms part of a robot.

10. The method of claim 1, wherein the device forms part of a commercial appliance.
