Abstract

See full text

A system for selectively controlling visibility of information in an environment is provided. The system includes one or more polarized emissive screens and polarized non-emissive surfaces located within the work environment. The screens have a first direction of polarization and the surfaces have a direction of polarization substantially aligned with the first direction of polarization. Information displayed on the screens and surfaces are visible to a person inside the work environment. The work environment includes at least one window which permits viewing of the polarized emissive screens and non-emissive surfaces from outside of the work environment. A polarizing filter having a second direction of polarization arranged at an angle to the first direction of polarization is positioned proximate to the window. A person outside the work environment can see inside the environment through the window, but has an altered view of the information on the displays and surfaces.
