System, method and article of manufacture for detecting collisions between video images generated by a camera and an object depicted on a display

A computer program embodied on a computer readable medium for detecting interactions between video images and an object depicted on a display, comprising:

• a code segment for receiving video images having a person image;
• a code segment for 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;
• a code segment for 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 determining valid ranges of motion based on the estimated location of the head and the estimated location of the torso of the person image in the video images;
• and
• a code segment for depicting the interaction between the video images and the object depicted on the display based on the first confidence value and the second confidence value.

A system for detecting interactions between video images and an object, comprising:

• an input device for receiving video images;
• logic for 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;
• logic for 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 determining valid ranges of motion based on the estimated location of the head and the estimated location of the torso of the person image in the video images;
• and
• a display for depicting the interaction between the video images and the object based on the first confidence value and the second confidence value.
