Method for Correcting Erroneous Results in Online Handwritten Character Recognition

       Disclosed is a method for correcting an erroneous result
in online handwritten character recognition by rewriting it as a
syllabic character instead of simply rewriting the same character.

      Existing methods allow the user to correct an erroneous result
by rewriting the same character or by selecting from a menu of
recognition candidates.  The problems are that the former tends to
give the same erroneous result, since both the writer and the
character to be rewritten are the same, while the latter cannot
display many candidates, since they occupy an area of the screen
proportional to their number.

      The disclosed method allows the user to correct an erroneous
result by writing the first syllabic character of the word for the
input character.  For example, when a user writes "0 (the numeral
zero)" and it is recognized as "O (alphabetic)", he/she can write "z"
to correct the erroneous result. After "z" has been recognized, the
candidate "0", which has "z" as the first syllabic character of its
word form, is selected for the corrected result.  The recognition
accuracy for "z" is high, since the number of syllabic candidates is
small. For characters with multiple readings, such as Japanese Kanji,
any one of the first syllabic characters is acceptable.

      Consequently, the disclosed method solves the problem of the
first above-mentioned type of method by a...
