Abstract
Methods and systems for projecting images that may be implemented to provide the ability for a user of an information handling system to view a selected projected image privately, while allowing other projected images to be publicly viewable to other users who cannot see the privately-projected image. With appropriate intervening polarization, a user may be allowed to view the projected private image and any projected publicly viewable images, and the private image and publicly viewable images may be optionally simultaneously projected if so desired.
