1. A system for controlling the scrolling of a display comprising:
- an input device having a rotational member including a wheel having at least a wheel portion extending from an outer surface;
said wheel portion being configured to receive a manual movement to provide rotation of said rotational member; and
means for monitoring a first rate of rotation of said rotational member and a second rate of rotation of said rotational member in which said first rate and said second rate are different, said means configured to calculate to calculate a relative rotational rate between said first rate and said second rate, said means outputting at least one scroll signal for controlling the scrolling of said display in relation to said relative rate.

Abstract
A system and method for accelerating scrolling of a display is disclosed. When a wheel of a wheeled pointing device is actuated by a user at a first rotational rate, the display in a window scrolls up or down one line at a time. When the wheel is rotated at a second rotational rate, the display in the window scrolls up or down multiple lines at a time. In additional embodiments, the scrolling technique shifts from one line at a time/multiple lines at a time to a page or pages at a time when the wheel is rotated for at a rotational rate for a minimum period of time.

11. A system for controlling the scrolling of a display comprising:
-
means for receiving signals indicative of the operation of a rotational member including a wheel on a computer input device;
said wheel having at least a portion extending from an outer surface of the input device;
said portion being configured to receive a manual movement to provide rotation of said rotational member;means for processing said signals in accordance with a first rate of rotation of said rotational member and a second rate of rotation of said rotational member in which said first rate and said second rate are different, determining a relative rotational rate between said first rate and said second rate; and means for outputting scroll control signals in accordance with said means for processing. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)
