Disclosed is a list of user interface choices controlled by a rotating dial.
a list of user interface choices controlled by a
dial is analogous to a control often used on
hardware (not software) control panels. The hardware version of this
control is a knob with a cutout in the flange surrounding it which
has an opening through which the user sees one of the labels under
To change the
item selected, the user either drags along the
edge of the knob using a mouse to "turn" the knob or the click on the
center of the choice wheel which increments the item by one position
for each click.
The choice wheel is illustrated in the Figure.
Alternatives: The functionality
provided by the present
invention is available using a spin box or scrolling list commonly
available in interfaces today. The advantage of the choice slider
over either of these existing controls is that it is analogous to a
hardware control that most computer users are already familiar with.
Spin boxes and scrolling lists have no analogy outside of graphical
interfaces and thus must be learned by every new user.
