surrounding the selected control item by a border to indicate to
the viewer that the selected control item has the focus."
Col. 4, lines 27-31. For example, a focus ring 105 surrounds the
perimeter of control item 102 in Fig. 3A (col. 20, lines 22-24;
col. 27, lines 29-32). It can be seen that the focus ring
enlarges the visual representation of the control item. Standard
focus items include rings, arrows, and pointing fingers (col. 27,
line 38). Volk also discloses a button control object 810 in
Fig. 8A that executes a single action (col. 28, lines 51-53),
having an activated and deactivated modal state, where the visual
representation is changed to have the appearance of a depressed
(pushed) key when the key is pressed. The invention of Volk is a
system for highlighting the currently selected control item by
associating an animated "focus item," called a "sprite," with the
selected control item to indicate that it is in a state
responsive to commands from a user interface (abstract; col. 12,
lines 29-31). Volk teaches using multiple focus items in
discussing animated focus items, such as varying the size, shape,
position, color, moving images, video, sound "or a combination of
these elements" (abstract).
Greanias discloses a combined finger touch and stylus
detection system for use on the viewing surface of a visual
display system (abstract).
