Abstract: Improved computer interface system using multiple independent graphical data input devices is disclosed. Multiple independent graphical data input devices allow users to input data independently from multiple independent graphical data input devices to operating system. Graphical input device driver decodes input from multiple independent graphical input devices. Operating system interface software interprets data from graphical input device driver. Operating system software further generates and controls multiple cursors or control points. Graphical input device aware program obtains and interprets graphical input devices event message, and controls graphical input device aware objects.
