Appeal No. 1997-1665 Page 2
Application No. 08/289,134
The inventive handwriting recognizer includes a display
and a transparent input tablet formed thereon. A user
"writes" on the tablet with a stylus. The coordinates of the
movement of the stylus on the tablet, which represent the
user's handwriting, are recorded and the "strokes" of the
stylus and are displayed. Certain featured characteristics of
the coordinate data are calculated, i.e., extracted.
Specifically, the characteristics may include a direction and
length of lines, a radius and center angle of arcs, an angle
made by lines or the vertex angle of loops, and a number of
loops represented by the data. By calculating and considering
only these certain characteristics of the handwriting, the
invention can recognize handwriting quickly.
Claim 1, which is representative for our purposes,
follows:
1. A handwriting input display apparatus
comprising:
display means for displaying either a line
segment or a character, corresponding to a
calculation result of a computer;
tablet means, at least a portion of which is
transparent, and formed on said display means, for
providing coordinate data in response to an
operation;
