This paper introduces a method for quantitative analysis of the human recognition function in the discrimination of handwritten ambiguous characters. The authors developed this method from research on 'functional attributes' by Blesser et al. (1973). Hayashi's Quantification, Model II, was applied in order to extract the human discriminant function for recognition of ambiguous Japanese katakana letters. The obtained discriminant function could make highly reliable prediction regarding human ability to read labels of ambiguous letters, and the indices on features which contribute to the discrimination were obtained. The validity of this method was confirmed by various psychological experiments. Analysis using this method also quantitatively clarified the ingenious mode of human communication mediated by unconstrained handwritten letters. This method will contribute to the discrimination of other ambiguous characters among different letter sets, e. g. alphanumeric-kana or kanji-kana letters.
