Relationship between the construction of Chinese character and the correct ratio of writer indentification

The relationship between the correct ratio of the writer identification and the construction of the character was investigated. Thirty subjects were asked to write 32 kinds of Chinese characters 6 times. Coordinates of each stroke of the characters were measured. After the standardization of the origin and the size, the writers were classified and identified using multidimensional Euclidean distance. In Experiment 1, the number of strokes had little effect on the correct ratio of the identification. In Experiment 2, the relationship between the arrangement of the components of a character and the correct identification ratio was observed. These results were explained by the investigation into the stroke order, pen direction, and interaction between components along with geometrical construction. The results suggest that the investigation based on the motor aspects of writing motion is necessary to the handwriting examination
