Handheld vision based absolute pointing system
First Claim
1. A method, comprising:
- identifying one or more images of respective one or more fixed markers, each marker positioned on or proximate to a display, said images appearing on a pixilated sensor within a handheld device;
determining a location on, or proximate to, said display where said handheld device was pointed during said identifying;
sending from said handheld device information derived from said identifying of said one or more images of respective one or more fixed markers; and
, triggering action taken by electronic equipment circuitry in response to said handheld device'"'"'s sending of a signal to indicate said action is desired.

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.
