This disclosure describes a system of ceiling mounted laser projectors that can display bright visual indications, e.g., arrows, of a path to direct users to a next work location. The techniques of this disclosure can be implemented in various ways. For example, the projected arrow can move as the user moves; a visual path is projected for the next few seconds of transit time or the whole of the path going to the next task; different shapes or colors are projected to indicate different workers or tasks; etc. For different spaces, with different aspect ratios, different numbers of laser projectors may be installed. The techniques of this disclosure can also be used to illuminate the paths of Automated Guided Vehicles (AGV) or robots.
