Summary of first study : A character learning system needs having the function of evaluating hand-written characters written by learners. We proposes a method of introducing gradation processing and Directional Line-element Entropy (DLE) into evaluation of hand-written character patterns.The variation values, which were subjectively evaluated by some subjects for sample characters, were not able to agree with the ones evaluated by the previous method in the case of the samples with small variation. But they were able to agree with the ones by the proposed method. The variation values for the samples can be presumed with only about 30 characters.Summary of second study : If the document can be written with hand-written style fonts in computer education, it has a good effect on pupils. After user's hand-written characters were collected on every category of characters, each stroke of the characters was converted into the time series pattern of directional line-element. We experimentally generated hand-written style character sets with character variation, based on the distribution of the weight obtained by the gradation processing using fuzzy rules. Then the variation of the generated characters about the position of their line-element was larger than that about the direction of their line-element.

研究一：一个汉字学习系统需要具备对学习者手写的汉字进行评价的功能。本文提出了一种将灰度处理和方向性线元熵（DLE）引入手写体字符模式评价的方法，在样本变化较小的情况下，一些受试者对样本字符的主观评价结果与以前的方法评价结果不一致。但他们能够同意所提出的方法。样本的变异值可以用大约30个字符来推测。研究二总结：在计算机教学中，如果文档可以用手写体字体书写，对小学生有很好的效果。在每一类字符上采集用户手写字符后，将字符的每一笔都转换成方向性线元的时间序列模式。我们实验产生的手写体风格字符集的字符变化，根据使用模糊规则的灰度处理得到的权重分布。生成的字符线素位置的变化大于线素方向的变化。
