ABSTRACT:
A widget, a predefined region of a graphical display, and a graphical pointer or cursor are displayed on the display device. A user may define a gravitational widget where traversal rates are not constant on the display. In addition, relationships may be defined which correlates manipulation of the graphical pointing device, the movement of the graphical pointer and a widget. Certain users may be denied access to one or more widgets. When the graphical pointer contacts the border of the widget, the graphical pointer may be denied access to the widget by controlling the graphical pointer. Control of the graphical pointer is accomplished through a defined relationship or action rule. Various action rules forbidding access to a widget include moving or displacing the graphical pointer to a home position, skipped over the widget with the graphical pointer, freezing or sticking the graphical pointer to the widget, displacing the graphical pointer to a random location on the screen, rebounding the graphical pointer, racing the graphical pointer around the widget's border, and repeatedly backing-up and moving forward the graphical pointer. Two or more action rules may be combined so that multiple movements may be achieved.
