Gestural interaction identification

摘要

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.

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.
