User interactive cursor control in a computer controlled display system with supplemental mouse lighting to aid in cursor positioning

摘要

A visual indication on a cursor control device is triggered when the cursor is within a designated region on said display screen. Usually the user activated cursor control device is a computer control mouse, but the invention may operate effectively with joy sticks and trackballs. An effective implementation provides a light on the control mouse and the target region on the display screen for the cursor is an icon. The light on the mouse may be a variable light. It may be varied dependent upon the type of region on the screen which is the target region, e.g. one type of light if the target region is a display window and another type of light if the target region is an icon. The variation in the light may be light intensity or color.
