Abstract
A method is described that involves identifying one or more images of respective one or more fixed markers. Each marker is positioned on or proximate to a display. The images appear on a pixilated sensor within a handheld device. The method also involves determining a location on, or proximate to, the display where the handheld device was pointed during the identifying. The method also involves sending from the handheld device information derived from the identifying of the one or more images of respective one or more fixed markers. The method also involves triggering action taken by electronic equipment circuitry in response to the handheld device's sending of a signal to indicate the action is desired.
