这项研究阐明了以前建立的盲文阅读新手通过听觉获得盲文信息的方法。其中，用户用具有盲文转语音功能的笔型界面触摸盲文附近。二维（2D）点码被印刷在盲文纸上，并且与盲文相对应的语音信息被链接到这些点码。本研究旨在建立有关二维点码打印区域可接受尺寸的定量数据。招募了 9 名盲文阅读新手，蒙着眼睛，没有盲文阅读经验，参与一项实验，要求他们识别盲文字符中的六个点中缺少哪一个，将笔型界面触摸到铺有点代码打印区域和 TRUCT 盲文的纸张上，并从 1 到 5 的等级评估系统的有效性。所有参与者都正确识别了缺少的点。参与者对盲文转语音功能的平均有效性评分为 4.6/5.0，标准差为 0.7。点码打印区域被确定为盲文字符的点 2 和点 5 之间的中点上方 8 毫米和下方 10 毫米，距离盲文中点的宽度为 16 毫米。基于这些结果，确定了点码打印区域的设计准则，以提高通过配备盲文转语音功能的笔型接口获取与盲文对应的语音信息的成功率。这在针对盲文阅读新手的盲文教育方法中具有许多潜在的应用。
This study clarifies a previously established method in which Braille reading novices obtained Braille information aurally. Therein, users touched the vicinity of the Braille with a pen-type interface characterized by a Braille-to-voice function. Two-dimensional (2D) dot codes were printed on the Braille paper, and voice information corresponding to Braille was linked to these dot codes. This study aims to establish quantitative data regarding an acceptable size for the 2D dot code printing area. Nine Braille reading sighted novices, blindfolded and without Braille reading experience, were recruited to participate in an experiment, where they were asked to identify which of the six dots in a Braille character were missing, touch the pen-type interface to a sheet layered with the dot code printing area and TRUCT Braille, and evaluate the system’s effectiveness on a scale from 1 to 5. All participants correctly identified the missing dot. Participants gave the Braille-to-voice function an average effectiveness rating of 4.6/5.0, with a standard deviation of 0.7. A dot code printing area was determined to be 8 mm above and 10 mm below the midpoint between dots 2 and 5 of the Braille character, with a width of 16 mm from the midpoint of the Braille. Based on these results, design guidelines were identified for the dot code printing area to improve the success rate of obtaining voice information corresponding to the Braille with the pen-type interface equipped with the Braille-to-voice function. This has numerous potential applications in Braille education methods for Braille reading novices.
