In this study, we examine different approaches to the presentation of coordinates in mobile auditory graphs, including the representation of negative numbers. These studies involved both normally sighted and visually impaired users, as there are applications where normally sighted users might employ auditory graphs, such as the unseen monitoring of stocks, or fuel consumption in a car. Multi-reference sonification schemes are investigated as a means of improving the performance of mobile non-visual point estimation tasks. The results demonstrated that both populations are able to carry out point estimation tasks with a good level of performance when presented with auditory graphs using multiple reference tones. Additionally, visually impaired participants performed better on graphs represented in this format than normally sighted participants. This work also implements the component representation approach for negative numbers to represent the mapping by using the same positive mapping reference for the digit and adding a sign before the digit which leads to a better accuracy of the polarity sign. This work contributes to the areas of the design process of mobile auditory devices in human-computer interaction and proposed a methodological framework related to improving auditory graph performance in graph reproduction.
在本研究中，我们考察了在移动听觉图中呈现坐标的不同方法，包括负数的表示。这些研究涉及视力正常和视力受损的用户，因为在某些应用中，视力正常的用户可能会使用听觉图，比如对股票的无形监测，或汽车的油耗监测。我们研究了多参考声化方案，以此作为提高移动非视觉点估计任务性能的一种手段。结果表明，当向两组人群呈现使用多个参考音调的听觉图时，他们都能够以良好的性能水平执行点估计任务。此外，视力受损的参与者在以这种格式呈现的图表上的表现优于视力正常的参与者。这项工作还实现了负数的组件表示方法，即通过对数字使用相同的正映射参考并在数字前添加符号来表示映射，这提高了极性符号的准确性。这项工作为人机交互中移动听觉设备的设计过程领域做出了贡献，并提出了一个与提高听觉图在图形再现中的性能相关的方法框架。
