Abstract:
1. A method of remotely controlling position of a cursor or other object displayed on a display, comprising: imaging an area in front of the display, the area including a user movable target object; detecting one or more candidate target object locations in the image; detecting an approximate location of the best candidate target object as the target object in the image; determining a more accurate location of the target object employing grayscale data of the area of the candidate target object location in the image; and employing the more accurate location of the target object to control position of a cursor or other object displayed on the display; wherein detecting an approximate location of the best candidate target object in the image comprises correlating the image data with a grayscale template corresponding to a typical target object pattern; and wherein determining a more accurate location of the target object comprises performing a center of gravity calculation using the original grayscale data from the image in the area of the candidate.
