A directionally active projection device is described that includes a planar display providing a pattern of information. The planar display includes regions of light transparency and regions for blocking light transmittance. The directionally active projection device also includes a lens arranged adjacent to the planar display, and a collection of light sources arranged as an array in a focal plane of the lens. Also described are methods of controlling directionally active projection devices.
