of said selected portion of said display area relative to said display screen”; and “means
for automatically adjusting said calibration data stored in said touch memory to re-align
said coordinates generated by said touch processor to features of said image in response
to said correction data.” We note that the disclosed embodiment corresponding to the
language is described in the specification at page 13, lines 12 through 27.
On page 4 of the Answer’s statement of the rejection, the examiner refers to text at
column 2, lines 9 through 13 of Mussler which describes the object of providing an
“automatic touch screen calibration method.” The examiner also refers to column 5, line 23
to column 6, line 54 of the reference, at the bottom of page 5 of the Answer. That portion of
Mussler describes generation and use of a “coordinate translation matrix.”
The “coordinate translation matrix” is used in the preferred embodiment of Mussler
for translating touch screen coordinates into display coordinates. As described in
particular at column 5, line 50 though column 6, line 54, a “set of ten terms” is stored during
the initial calibration routine. As shown in equations 8 through 17 in column 6, each of the
terms (calib(0) through calib(9)) are generated from values derived from sensing touches
at points 45, 50, and 55 on the graphic display (see Fig. 4).
The examiner’s findings with respect to what Mussler teaches are unclear. Although
Mussler is provided to “teach automatic calibration,” the final paragraph of page 5 of the
Answer, for example, suggests that there is to be modification of the “automatic
