Method, apparatus and computer program product for recognizing a gesture
First Claim
1. A method for recognizing a gesture comprising:
- determining one or more relationships between a plurality of body parts, wherein determining each relationship comprises;
determining an angle associated with at least one joint; and
determining one or more states of a body part based upon the angle associated with at least one joint; and
determining a probability of the body part being in each respective state; and
determining the gesture with a gesture recognition unit based upon the one or more states and the probability associated with each state of the body part, wherein determining the gesture comprises identifying one or more candidate gestures having respective probabilities of being the gesture and reporting that the gesture was not recognized in an instance in which the respective probabilities fail to satisfy a predefined threshold.

Abstract
A method, apparatus and computer program product are provided for recognizing a gesture in which one or more relationships are determined between a plurality of body parts and the gesture is then determined based upon these relationships. Each relationship may be determined by determining an angle associated with at least one joint, determining one or more states of a body part based upon the angle associated with at least one joint, and determining a probability of a body part being in each respective state. The gesture may thereafter be determined based upon the one or more states and the probability associated with each state of the body part. Directions may be provided, such as to an unmanned vehicle, based upon the gesture to, for example, control its taxiing and parking operations.

8. An apparatus for recognizing a gesture comprising:
-
a processor configured to determine one or more relationships between a plurality of body parts, wherein the processor is configured to determine each relationship by; determining an angle associated with at least one joint; and determining one or more states of a body part based upon the angle associated with at least one joint; and determining a probability of the body part being in each respective state, and wherein the processor is configured to determine the gesture based upon the one or more states and the probability associated with each state of the body part, and wherein the processor is configured to determine the gesture by identifying one or more candidate gestures having respective probabilities of being the gesture and reporting that the gesture was not recognized in an instance in which the respective probabilities fail to satisfy a predefined threshold. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A computer program product for recognizing a gesture, wherein the computer program product comprises at least one computer-readable storage medium having computer-executable program instructions stored therein, the computer-executable program instructions comprising:
-
program instructions configured to determine one or more relationships between a plurality of body parts, wherein the program instructions configured to determine each relationship comprise; program instructions configured to determine an angle associated with at least one joint; program instructions configured to determine one or more states of a body part based upon the angle associated with at least one joint; and program instructions configured to determine a probability of the body part being in each respective state; and program instructions configured to determine the gesture based upon one or more states and the probability associated with each state of the body part, wherein the program instructions configured to determine the gesture comprise program instructions configured to identify one or more candidate gestures having respective probabilities of being the gesture and program instructions configured to report that the gesture was not recognized in an instance in which the respective probabilities fail to satisfy a predefined threshold. - View Dependent Claims (16, 17, 18, 19, 20)
