MAGNIFICATION INTERFACE WITH INDEPENDENT POINTER SIZING

摘要

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.

主权项

1. A non-transitory computer-readable medium having stored thereon computer-executable instructions that, in response to being executed by a computing device, cause the computing device to perform operations comprising:
displaying a graphic user interface (GUI) at a GUI magnification level; displaying a pointing indicium at a pointing indicium magnification level; establishing a convergence value, wherein magnification of the GUI and the pointing indicium is synchronized when the GUI magnification level is below the convergence value and desynchronized when the GUI magnification level exceeds the convergence value; concurrently increasing or decreasing the GUI and the pointing indicium magnification levels when the GUI magnification level does not exceed the convergence value; increasing or decreasing the GUI magnification level independently of the pointing indicium magnification level when the GUI magnification level exceeds the convergence value, whereby the pointing indicium is displayed at a static size while the GUI is displayed at the GUI magnification level exceeding the convergence value; and responsive to GUI magnification level falling below the convergence value, resynchronizing the GUI and the pointing indicium magnification levels, whereby the GUI and the pointing indicium magnification levels are concurrently increased or decreased when the GUI magnification level does not exceed the convergence value.
