Audio/Visual Feedback for Touch Selection on Liquid Crystal Display
Screen

      Disclosed is method providing audio and visual feedback for the
selection of an icon or button by pressing a portion of a
touch-sensitive Liquid Crystal Display (LCD) screen on which the icon
or button is displayed.

      With this method, when the screen is first touched in a
selectable area, a low-pitched, short-duration click tone is
produced.  The icon or button touched is simultaneously
reverse-shaded, and any text contained within the icon or button is
shifted slightly downward and to the left.  Thus, the user can see
and hear that he has activated the icon or button area.  However, the
icon or button is not selected until the user removes pressure from
that area.  If the intended icon or button is missed, the choice can
correct by moving a finger to the correct position before removing
pressure to effect selection.  As the finger moves, the appearance of
each icon or button being depressed is changed to indicate its
potential selection.  When pressure is released to select an icon or
button, a louder, high-pitched tone is produced.

      This method is particularly useful when it is applied to a
small screen on which a relatively large number of icons or buttons
may be displayed, such as a full typewriter-style keyboard having
small keys.
