In this study, we discovered that minimum readable font size of low vision children is about 3 points larger than that of sighted people in the comparative experiments of reading fonts. We developed fonts for low vision children based on the results of the experiments. The fonts we have developed are formulated in the characteristics of those voiced sound marks being about 4 times as large as normal fonts. In order to assess the availability of developed fonts for low vision children, we conducted the comparative experiment using developed fornts and normal fonts. In the experiments, we checked the readability of developed fonts, and we found that percentage of questions about reading words printed with developed fornts are much inclined in comparison with the results of initial experiment. We suppose this makes it clear that developed fonts are useful for low vision children.

本研究通过阅读字体的对比实验发现，弱视儿童的最小可读字体大小比正常人大3个点左右。我们根据实验结果开发了适合低视力儿童的字体。我们开发的字体是根据这些浊音标记的特点制定的，其大小约为普通字体的4倍。为了评估开发字体对于弱视儿童的可用性，我们使用开发字体和普通字体进行了对比实验。在实验中，我们检查了开发字体的可读性，发现阅读开发字体打印的单词的问题百分比与最初的实验结果相比有很大的倾斜。我们认为这清楚地表明开发的字体对于弱视儿童很有用。
