Polarized enhanced confidentiality

摘要

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.

1. A system for controlling visibility of information in an enclosed work environment, the system comprising:
one or more polarized electronic screens located within the enclosed work environment, wherein the one or more polarized electronic screens have a first direction of polarization and wherein information displayed on the one or more polarized electronic screens is visible to a person inside the enclosed work environment; one or more polarized non-electronic surfaces located within the enclosed work environment, wherein the one or more polarized non-electronic surfaces have a direction of polarization substantially aligned with the first direction of polarization of the one or more polarized electronic screens and wherein information displayed on the one or more polarized non-electronic surfaces is visible to the person inside the enclosed work environment; wherein the enclosed work environment is enabled to allow for a person to have a view within the work environment including viewing of the one or more polarized electronic screens and non-electronic surfaces from outside of the enclosed work environment; and a polarizing filter positioned proximate to and extending across a camera lens, wherein the polarizing filter has a second direction of polarization and wherein the second direction of polarization is arranged at an angle to the first direction of polarization; wherein a person outside of the enclosed work environment can see inside of the enclosed work environment through the camera lens, but has a similarly altered view of the information on the one or more polarized electronic displays and one or more polarized non-electronic surfaces.
