The present study aimed to investigate whether the laws of isochrony and homothety hold for Japanese characters by measuring handwriting movements using a liquid crystal display tablet. The law of isochrony means that handwriting time is constant regardless of handwriting size. The law of homothety means that the time required for each character is consistent regardless of the overall time required during continuous handwriting. The twenty-two participants made three shapes, four hiragana characters (Japanese phonetic alphabets),and four kanji characters (Chinese characters) on a tablet at various sizes and speeds. Total handwriting time was longer when character size increased for all character types. This result suggests that the law of isochrony does not hold for Japanese character types. When the characters were written sequentially, the partial handwriting time ratio was indefinite and, varied by character. This result suggests that the law of homothety might not hold for some characters. In summary, this study suggests that the spatiotemporal dynamics of handwriting in Japanese differ by character.
