Title:
VECTOR-BASED MAGNIFIED POINTER
Document Type and Number:
WIPO Patent Application WO/2011/002981
Kind Code:
A3
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.
