  • Patent number: 5880717
    Abstract: A method and means for the control of a cursor upon a display screen of a computer system by a pointed object such as a pen, stylus, or finger upon an electrical writing surface is disclosed. The method and means will allow the cursor to continue to scroll across the display screen in a fixed direction and at a fixed speed once the pointed object has transited from a workzone region to an edgezone region of the touchpad. Once the pointed object is in the edgezone region, the pointed object may be stopped. If a different direction or speed of movement of the cursor is desired, the pointed object can be moved in the new direction to establish the new direction and speed of movement of the cursor. The control of the cursor will return to the normal movement when the pointed object returns to the workzone from the edgezone.
