Abstract

A window system for a passenger compartment of a vehicle includes a transparent window having a window treatment, an incident light monitoring subsystem, an incident light management subsystem and a controller. The incident light monitoring subsystem monitors incident light transmitted into the passenger compartment, determines a field of view of a passenger and determines an intensity of the incident light relative to the field of view of the passenger. The incident light management subsystem individually controls a plurality of light projectors to project a light beam that interacts with a subsection of the window treatment to modulate light transparency of one of the subsections of the window based upon the intensity of the incident light in relation to a field of view of the passenger.
