Abstract
A system and method for positioning a cursor associated with a dynamic background is described. In a first step, the position of the dynamic background in a first frame is calculated. In a second step, the position of the dynamic background in a second frame is calculated. In a third step, the change in position of the dynamic background from the first frame to the second frame is calculated. Lastly, the position of the cursor in the second frame is adjusted according to the change in position of the dynamic background. The change in position of the dynamic background from the first frame to the second frame can be calculated in one, two or three dimensions. Likewise, the position of the cursor in the second frame can be adjusted in one, two or three dimensions. This advantage allows for easier positioning of the cursor by a user on a desired object in the display.
