Appeal No. 1996-3362
Application No. 08/258,601
DECISION ON APPEAL
This is a decision on appeal from the final rejection of
claims 3 through 6, all of the claims pending in the present
application. Claims 1 and 2 have been cancelled.
The invention relates to a device and method for
controlling cursor motion on a display screen of a computer.
In particular, the invention provides two modes of cursor
operation, an absolute mode and a relative mode. In the
absolute mode, the cursor position on the display screen is
determined by the operator's finger position on the touch
screen. In the relative mode, the cursor position on the
display screen is determined relative to the operator's finger
touch screen position. The selection between these two modes
is done by the operator pressing against the screen by a force
that exceeds a threshold.
Independent claim 5 is reproduced as follows:

signals indicating X-Y position coordinates of an operator's
finger in contact therewith and a force exerted by said finger
thereon, said signals being transmitted to a processor
comprising means for positioning the cursor on the display
screen according to an absolute pointing mode wherein each
