基于块的编程应用程序,例如 MIT 的 Scratch 和 Blockly Games,通常用于教 K-12 学生编码。由于 COVID-19 大流行,许多 K-12 学生正在参加在线编程训练营,该训练营教授使用这些基于块的应用程序进行编程。然而,盲人/低视力 (BLV) 人群无法使用这些应用程序,因为它们既不产生音频输出,也无法使用屏幕阅读器。在本文中,我们描述了一种解决方案,使 BLV 学生可以使用 Google 最新的键盘导航进行基于块的编程,并由四位 BLV 人员进行评估。我们将我们的发现提炼出来,作为对那些可能希望让 BLV 个人可以访问其基于块的编程应用程序的开发人员的建议。
Block-based programming applications, such as MIT’s Scratch and Blockly Games, are commonly used to teach K-12 students to code. Due to the COVID-19 pandemic, many K-12 students are attending online coding camps, which teach programming using these block-based applications. However, these applications are not accessible to the Blind/Low Vision (BLV) population since they neither produce audio output nor are screen reader accessible. In this paper, we describe a solution to make block-based programming accessible to BLV students using Google’s latest Keyboard Navigation and present its evaluation with four individuals who are BLV. We distill our findings as recommendations to developers who may want to make their Block-based programming application accessible to individuals who are BLV.
