selection between these two modes is done by pressing a key on
the keyboard and not a pressure-activated switch on the
displaying mean. See column 7, lines 45 through 49. We also
find that Levine teaches a pressure-activated switch, 22e,
disclosed in column 6, lines 31 through 68. However, the
pressure-activated switch is disclosed to emulate the
functions of a one button mouse as found on the Apple
MacIntosh Computer which is used not to select between modes
for the cursor but instead used in the normal mouse click
function. Thus, we find that Levine fails to teach using a
pressure sensitive switch to select between the relative
pointing mode and the absolute pointing mode of the cursor.
Turning to Faulkerson, we fail to find that Faulkerson
teaches using a pressure switch, in which a predetermined
threshold is determined, to select between two modes. In
particular Faulkerson merely has a plurity of switches 26a
through 26e shown in Figure 1 which are used to operate either
the optical scanner or the computer mouse. We fail to find
that Faulkerson teaches selecting between two modes by
comparing a force with a predetermined threshold.
