produced when transitioning from the “NO TOUCH” state (102) to the
“BLANK” state (100). The “NO TOUCH” state is entered when the finger
is not touching the touch panel and the “BLANK” state is entered when the
finger touches the background area of the touch panel—the area not within
any virtual button (col, 8, ll. 41-47). In addition, an “UP-AUDIO RIDGE”
sound is produced when the finger moves from the background area to a
particular button, while a “DOWN-AUDIO RIDGE” sound is produced
when the finger moves from the button to the background area (col. 9, ll. 46-
58). Hence, Vanderheiden discloses that some type of sound (background,
UP-AUDIO RIDGE, or DOWN-AUDIO RIDGE) is produced in the second
mode of operation when the finger touches the touch panel.2 In contrast,
these sounds are disabled in the first (non-audio) mode of operation and
therefore no sound is produced when the finger touches the touch panel (col.
6, ll. 18-26).
During operation, Vanderheiden explains that the second mode of
operation can be activated by pressing against the upper right hand corner
(56) on the display and drawing leftward at least half way across the top of
2 Vanderheiden explains that no sound is generated in the second mode of
operation when the finger is not touching the touch panel (col. 9, l. 64 to col.
10, l. 2). Vanderheiden describes this as the “NO TOUCH” state (col. 8, ll.
46-47).
