The present invention provides a method of modifying a classification
scheme for classifying hand-written characters to thereby make the
classification scheme user dependent. The classification scheme includes
a number of allographs, each allograph representing a respective style of
a respective letter. The method includes obtaining at least one
hand-written character, and then selecting an allograph representing the
character. One or more of the allographs are then modified in accordance
with the selection, to thereby reflect the fact that the allograph
corresponds to a style of letter used by the user.
