Abstract
According to an embodiment of the present invention, a method for operating an image display device using a pointing device includes receiving, from the pointing device, a first signal and a second signal to display a pointer at a particular location on a screen of the image display device, wherein the first signal initiates displaying of the pointer in accordance with a first input selection of the pointing device, determining whether coordinates corresponding to the second signal to display the pointer are outside an active area, wherein the active area is greater than an actual size of the screen, and resetting the coordinates to new coordinates corresponding to a pre-designated area of the screen and displaying the pointer at the pre-designated area of the screen when the coordinates are determined to be outside the active area.
