Exponential Increases in Spin Control Rates

      Disclosed are techniques that allow users to scroll through and
specify large numbers using only a pointing device and a control
similar to spin buttons.  The control is illustrated in the above
Figure.

      Next to the entry field is the familiar spin button control
consisting of up and down arrow buttons.  Associated with the buttons
is a scale labelled exponentially.  The scale can be positioned
either horizontally or vertically.  To use the control, the user
selects a directional arrow.  At this point the control scrolls the
values normally, one unit at a time.  If the user desires to increase
the rate of spin, he or she drags the arrow out over the scale.  The
further along the scale the user drags the arrow button, the faster
the rate of spin.  As the displayed value approaches the desired
value, the user drags the button to the left to slow down the rate of
spin.  The exponential markings on the scale indicate to the user the
level of spin rate.  As the level is increased, digits to the right
of the specified level effectively become blurred, allowing the user
to focus on the specified level.  Once the user releases the button,
it returns to its original position.
