Abstract: 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.

Abstract: A method of rendering customized pointing indicia including the steps of monitoring application program interface messaging and intercepting a call for a unique system pointer identifier. A stored collection of predefined vector shapes is accessed, from which a predefined vector shape is selected correlated to the current system pointer identifier. The stroke and fill attributes are set for the vector shapes. A sequence of rasterized frames of vector shapes having different attributes are created and displayed to produce animated pointing indicia effect. The customized vector shape is rasterized and displayed to an end user operating a computer. Customization, animation, and magnification of pointing indicia are performed responsive to user input, which may be a touchscreen event, body movement, hand gesture, mouse event, or a key stroke.

Abstract: A method of rendering magnified pointing indicia including the steps of monitoring application program interface messaging and intercepting a call for a unique system pointer identifier. A stored collection of predefined vector shapes is accessed and from that a predefined vector shape from the collection is selected which is correlated to the current system pointer identifier. A convergence point may be established for maximum pointing indicia magnification in addition to a user-selectable desktop magnification level. The vector shape is scaled in synchronization with the desktop magnification level up to the convergence point whereby the vector shape is no longer scaled up once the convergence point is reached. The scaled vector shape is rasterized and displayed to an end user operating a computer.

Abstract: A computer program for rendering a magnified graphic user interface (GUI) establishes a first magnification level for the graphic user interface and a second magnification level for a pointer. It displays the magnified GUI at the first magnification level and monitors application program interface messaging for a call for a system pointer identifier. It intercepts this call and scales the pointing indicia not to the magnification level of the GUI, but to the second magnification level for the pointer. The pointer is then displayed to an end user of the computer system at a magnification level that is different from the magnification level of the GUI. Thus, the invention provides for independent magnification of the graphic user interface from the mouse cursor or caret.
