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.

Magnification interface with independent pointer sizing

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.

Vector-based customizable pointing indicia

A method of magnifying text across a computer operating system platform, the method including the steps of loading a background text viewer process on a computer operating system, the background text viewer process having access to internal operating system messaging relating to text sent to a graphics display driver for presentation to an end-user on a GUI, drawing a text viewer on a portion of the GUI whereby the text viewer and a third party application that displays text are shown on the GUI concurrently, intercepting text originating from the third party application and sent to the graphics display driver, the interception performed by the background text viewer process, selecting a substring of intercepted text associated with an end-user focus on the third party application and displaying the substring on the text viewer according to end-user defined settings.

System wide text viewer

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.
