Abstract
A method for displaying a hologram to a variable direction including using circuitry to determine a direction from a holographic projector to a viewer for projecting a hologram to a viewer, and projecting a hologram in the determined direction, in which the projecting the hologram includes reflecting from a same mirror as the determining the direction of the viewer, and the circuitry controls the projecting the hologram to a direction corrected for a difference in direction between a projecting unit and a tracking unit relative to the mirror. Related apparatus and methods are also described.

A method for displaying a hologram to a variable direction comprising:
- using circuitry to determine a direction from a holographic projector to a viewer for projecting a hologram to a viewer;
- and
- projecting a hologram in the determined direction,
- in which:
- the projecting the hologram comprises reflecting from a same mirror as the determining the direction of the viewer;
- and
- the circuitry controls the projecting the hologram to a direction corrected for a difference in direction between a projecting unit and a tracking unit relative to the mirror.
Apparatus for displaying a hologram to a variable direction comprising:
- a hologram projection unit for projecting a hologram by reflecting from a mirror;
- and
- a viewer tracking unit for determining a direction from the hologram projection unit to a viewer, using the mirror for determining said direction by reflection off the mirror,
- wherein
- circuitry is used to control the projecting the hologram to the direction from the hologram projection unit to the viewer corrected for a difference in direction between the hologram projecting unit and the viewer tracking unit relative to the mirror.
