Abstract
A cursor positioning system for a computer display system includes a coarse positioning subsystem and a fine positioning subsystem. The coarse positioning subsystem provides a coarse positioning signal to a cursor control and rendering subsystem of a computer display system. The coarse positioning subsystem includes a voice recognition system. The coarse positioning signal provides coarse positioning of a cursor to a region of interest (ROI) on a computer display of the computer display system. The fine positioning subsystem is operatively associated with the coarse positioning subsystem for providing a fine positioning signal to the cursor control and rendering subsystem. The fine positioning signal provides fine positioning of the cursor within the ROI on the computer display. The fine positioning subsystem is operatively associatable with a cursor control device.
