Abstract: A head worn display (HWD) includes a projection system, which projection system in turn may include: a projection surface including a holographic optical element (HOE) centered at a first location; a projector to project light onto a projection area of the projection surface; and a controller to send a control signal to the projector to cause the projector to project an image onto a location shifted from the first location based on a misalignment of a user's line of sight with the first location.

Abstract: Disclosed herein are devices and methods to provide a display including a projection system and a lens including a holographic optical element to receive light and reflect the light to an exit pupil. The projection system is adapted to move the image projected onto the lens based on a location of the HOE within the lens.
