Establishment of a new objective evaluation index in handwriting and clarification of clumsiness factors

我们开发了一种新的手写评估系统，使用平板电脑，可以记录笔在书写任务中的轨迹和压力。我们研究了书写（绘画或书写）技能、视觉功能和书写表现之间的关系。对于绘画技能，正常男孩（2-6年级）的标准值是通过两次绘画任务计算得出的。对于书写易读性，使用字符的大小、空间和对齐来计算评估指数的标准值。绘画技巧、视觉功能和书写表现之间的关系如下：在眼动方面，外笔划长儿童与无外笔划长的儿童以及成人存在差异。对于书写表现的肢体动作描摹，外笔画长儿童的描摹时间比外笔画长儿童的描摹时间长，也比成人的描摹时间长。

We developed a new handwriting assessment system using a tablet PC that could record the pen's trajectories and pressures during handwriting tasks. We examined the relationship between handwriting (drawing or writing) skills, visual function, and handwriting performance. For drawing skills, the standard values for normal boys (Grades 2-6) were calculated from two drawing tasks. For writing legibility, the standard values were calculated for the evaluation index using size, space, and alignment of characters. The relationship between drawing skills, visual function, and handwriting performance was as follows. For eye movement, children with a long outside stroke length tended to be different from children with no outside stroke length as well as from adults. Regarding the tracing of body movements for handwriting performance, children with a long outside stroke length were longer compared to children with no outside stroke length as well as to adults.
