trackball


trackball
   A device used for pointing, designed as a space-saving alternative to the mouse.
   A trackball contains a movable ball that you rotate with your fingers to move the cursor on the screen. Because it does not need the area of flat space that a mouse needs, trackballs are popular with users of portable computers. The Apple PowerBook includes a trackball as part of the keyboard case, Microsoft has released a small trackball that clips onto the side of a laptop computer, and IBM has developed a dualbutton,touch-sensitivepointingstickcalled the TrackPoint.
