Gestural interaction identification
First Claim
1. A method of identifying gestural interaction comprising:
- detecting a user with an imaging device;
detecting with the imaging device the depth value at a centroid of the user with respect to the imaging device, comprising;
determining the centroid location of the user and the depth value of the centroid location;
detecting with the imaging device a closest distance of the user with respect to the imaging device, comprising;
determining a closest user feature within the image of the user; and
with a processor, identifying an initiation of a gestural interaction based on a ratio of the closest distance and the depth value at the centroid of the user is above a predetermined threshold.

Abstract
A method of identifying gestural interaction comprises detecting a user with an imaging device, detecting with the imaging device the depth value at the centroid of the user with respect to the imaging device, detecting with the imaging device the closest distance of the user with respect to the imaging device, and, with a processor, identifying the initiation of a gestural interaction based on the ratio of the closest distance and the depth value at the centroid of the user is above a predetermined threshold. A computer program product for identifying initiation and termination of gestural interaction within a gestural interaction system comprises a computer readable storage medium having computer usable program code embodied therewith, the computer usable program code comprising computer usable program code that identifies the initiation of a gestural interaction by a user depending on whether a virtual bubble around the user has been broken.

7. A gestural interaction system comprising:
-
an imaging device that detects a depth value at a centroid of a user and a closest distance of the user relative to the imaging device, including determining the centroid location of the user, a depth value of the centroid location, and a closest user feature within the image of the user; and a processor that identifies an initiation of a gestural interaction based on whether a ratio of the closest distance and a depth value at the centroid of the user is above a predetermined threshold. - View Dependent Claims (8, 9, 10)

11. A computer program product for identifying initiation and termination of gestural interaction within a gestural interaction system, the computer program product comprising:
-
a non-transitory computer readable storage medium having computer usable program code embodied therewith, the computer usable program code comprising; computer usable program code that identifies an initiation of a gestural interaction by a user depending on whether a virtual bubble around the user has been broken; computer usable program code that detects with an image device a user, a depth value at a centroid of the user with respect to the imaging device, and a closest distance of the user with respect to the imaging device, including determining the centroid location of the user, a depth value of the centroid location, and a closest user feature within the image of the user; computer usable program code that determines whether to initiate recognition of the user'"'"'s gestures as gesture interaction based on a ratio of a closest distance of the user with respect to an imaging device and a depth value at a centroid of the user compared to a predetermined threshold value. - View Dependent Claims (12, 13)
