Abstract
A system and method of identifying a point of interest of an object located in front of a computer controlled display area captured by an image capture device is performed by capturing an image of the display area within the capture area of the image capture device. Pixels within the captured data are identified that correspond to the object within the display area and to the peripheral boundary of the display area within the capture area. Pixels are identified and stored that correspond to the common subset of the object pixels and the peripheral boundary pixels. A search is performed using the common pixels and the object pixels to determine a pixel corresponding to the point of interest of the object in the display area within the capture area.
