Magnification interface with independent pointer sizing
View Patent ↗A computer program for rendering a magnified graphic user interface (GUI) establishes an initial magnification level for the graphic user interface and the pointing indicia. The GUI and the pointing indicia are magnified in synchronization until the magnification convergence point is reached. At magnification levels above the convergence point, magnification of the GUI and the pointing indicia becomes decoupled, and only GUI is magnified while the pointing indicia remain at the convergence magnification level. If the GUI magnification level falls below the convergence point, the magnification of GUI and the pointing indicia is recoupled and magnification becomes synchronized. Floor and ceiling magnification values for the pointing indicia may also be established.
