Abstract
Methods and apparatus for displaying a near-focus one-dimensional marker on a head up display (HUD) such that the parallax disparity between the marker and a distant far-focus visual target is not apparent to a viewer looking at the visual target through the HUD. The one-dimensional marker is oriented at the same angle as the interocular line of the viewer's eyes, as captured by a digital camera facing the viewer. Additionally, a dashed one-dimensional marker is disclosed to reduce the visual noticeability of small inaccuracies in orientation.
Claims15
A method for displaying, to a viewer, a marker on a head up display (HUD), the method comprising:
- determining a horizontal orientation angle relative to a predetermined reference line of the HUD;
- and
- displaying a one-dimensional marker having a marker orientation angle measured relative to the predetermined reference line of the HUD, wherein the marker orientation angle is substantially equal to the horizontal orientation angle.
Apparatus for controlling a head up display system, for displaying, to a viewer, a marker on a head up display (HUD), the apparatus comprising:
- a visual target identifier, for identifying a position of a visual target which the viewer is viewing through the HUD;
- and
- a marker display generator for controlling the HUD system to display a one-dimensional marker according to the position of the visual target, wherein an orientation angle of the one-dimensional marker relative to a reference line of the HUD is substantially equal to an orientation of an interocular line of the viewer's eyes relative to the reference line.
A computer product for a computer controlling a head up display system, for displaying, to a viewer, a marker on a head up display (HUD), the computer product comprising a set of executable commands contained within a tangible computer-readable non-transient data storage medium, such that when the executable commands of the computer product are executed, the computer product causes the computer and the head up display system to:
- determine a horizontal orientation angle relative to a predetermined reference line of the HUD;
- and
- display a one-dimensional marker having a marker orientation angle measured relative to the predetermined reference line of the HUD, wherein the marker orientation angle is substantially equal to the horizontal orientation angle.
