数学图表需要对视力障碍人士（PVI）开放。虽然触觉图形是PVI访问数学图形的常见方式，但在远程学习中，它们的使用变得复杂。为了使数学图形在远程教育中更容易获得，我们专注于发音，使用非语音声音。在本研究中，我们设计了数学图形的发音技术，将微积分中的不连续性概念引入PVI。首先，我们对六名参与者进行了远程采访，以了解他们使用图表进行数学教育的经验。基于这些发现，我们开发了一系列数学图形的声音化，并与我们最初采访的三名参与者进行远程评估。我们的研究结果表明，发音可以直观地传达简单的模式和趋势的数学图形与一点实践，是有用的介绍的不连续性，更有效的声音和图形的描述。
Math graphs need to be accessible to People with Visual Impairments (PVI). While tactile graphics are a common way for PVI to access math graphs, their use becomes complicated in remote learning. To make math graphs more accessible in remote education, we focused on sonification, the use of non-speech sound. In this study, we designed techniques of sonification of math graphs to introduce the concept of discontinuity in calculus to PVI. First, we conducted a remote interview with six participants to understand their experiences with math education using graphs. Based on these findings, we developed a series of sonifications of math graphs that we remotely evaluated with three participants from our initial interviews. Our findings reveal that sonification can intuitively convey simple patterns and trends in math graphs with a little practice, be useful to introduce the discontinuities, and be more effective with descriptions of the sound and graphs.
