ABSTRACT:
A passive optical marker for use in accordance with an electronic whiteboard system that selectively allows a reflector associated with the optical marker to be exposed to a light emitting source. Thus, the optical marker of the present invention selectively provides information pertaining to the location of the optical marker and pen-up/pen-down states.
