Patent Images
1. A system, comprising:
- a projection device to generate light representative of at least one virtual graphic;
an imaging matrix to project the light representative of the at least one virtual graphic on at least one image plane;
a display device to display the at least one virtual graphic on the at least one image plane; and
a translation device to dynamically change a position of the imaging matrix relative to the display device based, at least in part, on a predetermined operational parameter to dynamically vary a focal distance between the display device and the at least one image plane.
