Abstract
A projection system includes a light source and a lens. The light source includes a first light and a second light that both are positioned within a light source plane. The lens defines a principal axis and a lens plane that is normal to the principal axis. The light source is positioned relative to the lens such that the light source plane is oblique to the lens plane. The orientation of the light source relative to the lens enables the projection system to deliver information to a worker performing a task about the task being performed from a remote location that is outside of the area in which the worker is performing the task.
