Rotating Icon Selector

      Disclosed is a method allowing the user to make a selection
from a group of icons from a software-generated rotating wheel

      While the advent of operating systems having graphical user
interfaces has been a boon to most users of personal computers, many
users with physical disabilities lack the fine motor control needed
to easily and successfully operate a mouse.  Such users often find
graphical user interfaces significantly more difficult to use than
command-line interfaces.  In the use of a graphical user interface,
the ability to select an individual small picture of an object,
called an "icon," which is used to convey the meaning and purpose of
a program or data with which the user can interact, is of particular

      As shown in the Figure, a number of icons 10, which may be
individually chosen from a screen 12, are displayed in a circular
array rotating about a central axis in the direction indicated by
arrow 14.  While the center of each icon 10 is rotated with the
pattern, each icon 10 is itself maintained in a correct, non-rotating
orientation with respect to the horizontal.  Than is, the individual
icons 10 move as the cars of a ferris wheel.  At a fixed portion of
the path along which each icon moves, an activation area 16 is
visually indicated by a shaded box or other highlighting technique.
Pressing any key or button while the desired icon is in activation
area 16 causes that icon to be selected.  To improve usability, this
feature may be extended to include icons indicating actions which can
be taken on the selected window itself, such as maximize, minimize,
and close.

      Any input device activated by a single action, such as sip/puff
switch or a blink detector, developed to aid people with various
physical disabilities up to and including complete paralysis, can be
used in place of the depression of a key on the system keyboard to
indicate the selection of an icon in activation area 16.

      The speed of movement of the icons can be selected to meet the
needs of a particular user.  The relative location of activation area
16, at the top, bottom, or either side of the screen, may also be
chosen by the user.  The diameter of the "wheel" formed by icons 10,...
