Abstract:
A method of detecting interactions between video images and an object depicted on a display, comprising:receiving video images having a person image; executing a first interaction detection operation for generating a first confidence value representative of a confidence that a portion of the received video images has interacted with an object depicted on a display, wherein the first interaction detection operation is based at least in part on where the portion of the received video images first appeared and includes generating at least one of a speed and a direction of the object depicted on the display based on the interaction between at least one body part of the person image in the video images and the object depicted on the display; executing a second interaction detection operation for generating a second confidence value representative of a confidence that a portion of the received video images has interacted with the object depicted on the display, and determning valid ranges of motion based on an estimated location of a head and an estimated location of a torso of the person image in the video images; and outputting the first confidence value and the second confidence value, wherein the depiction of the interaction between the video images and the object depicted on the display is based on the first confidence value and the second confidence value.
