Abstract
An electronically shaded glass window system is described that provides a progressively darkening window, based on either user input or detection of ambient light. This invention is appropriate for use in commercial buildings, residential buildings, public areas and vehicles. It enhances energy efficiency by blocking bright light thereby reducing heat. It includes a user interface, which permits a user to create opaque or alternatively transparent walls or windows as the need arises.
