Abstract

This work introduces the "Letter Tracing", a serious game designed to teach correct letter formation. Co-designed through collaboration with clinicians and technicians, the game underwent testing with 9 first- and 26 second-grade children to assess its ability to capture the evolution of handwriting abilities over time and handwriting proficiency. In the game, children were asked to trace the initial two letters of 12 words following a demonstration of correct movements, in a gamified environment. A set of indicators derived from raw executions was computed and utilized to train diverse machine learning models, predicting both the grade and the risk of a handwriting delay as evaluated by a handwriting fluency test. The classification yielded an accuracy of 71% in predicting the grade and 71% in predicting the risk of handwriting delay. These results hold promise for the game's potential as a training tool, as it effectively models the maturation of children's handwriting and their proficiency.

字母追踪:通过机器学习教手写和评估熟练程度的严肃游戏。
本作品介绍了“字母描摹”,这是一个旨在教授正确字母构成的严肃游戏。通过与临床医生和技术人员合作设计,该游戏在9名一年级和26名二年级儿童中进行了测试,以评估其捕捉书写能力随时间和书写熟练程度的演变的能力。在游戏中,孩子们被要求在一个游戏化的环境中,跟随正确的动作示范,找出12个单词的头两个字母。从原始执行中得出的一组指标被计算出来,并用于训练不同的机器学习模型,通过书写流畅性测试来预测书写延迟的等级和风险。该分类在预测成绩和预测书写延迟风险方面的准确率分别为71%和71%。这些结果为游戏作为一种训练工具的潜力提供了希望,因为它有效地模拟了儿童笔迹的成熟和熟练程度。
