A wireless communication link is provided between the host computer and the digitizer such that a user's input can be transmitted from the digitizer, be received by the host computer, and be represented graphically on the display together with the image in real time, thereby permitting the user, associated with the digitizer, to personally provide input to the host computer displaying the image.
