1. A method of emulating a mouse input device with a touchpad input device, comprising:

  • designating a touch sensitive border area on the touchpad input device;

    determining the direction of movement of a touch device across the surface of the touchpad input device;

    causing a display cursor to move in the same relative direction as the determined direction;

    sensing when the touch device stops moving in the determined direction in a touch sensitive area excluding the border area and in response stopping the display cursor movement to allow the cursor to be positioned where desired; and

    sensing when the touch device stops moving in the determined direction after entering the border area and in response continuing the cursor movement in the relative direction to allow the cursor to be moved a greater distance than the touch device.
