虽然对非视觉访问视觉表示的信息的研究正在稳步增长，很少有工作调查如何通过非视觉手段构建这种形式的表示。我们在本文中讨论我们的方法提供音频访问关系图使用多个角度层次结构，并描述了两个交互策略的设计，通过这种方法来构建和操纵这样的图。我们与视力正常的用户进行的一项比较研究表明，非指导策略允许显着更快的交互时间，这两种策略支持类似水平的图表理解。总体而言，报告的研究表明，使用多个角度层次结构的关系图中编码的信息，使用户能够构建和操纵这样的信息，通过一个只有音频的界面，并结合方面的指导和非指导的策略，可以支持更大的可用性。
Although research on non-visual access to visually represented information is steadily growing, very little work has investigated how such forms of representation could be constructed through non-visual means. We discuss in this paper our approach for providing audio access to relational diagrams using multiple perspective hierarchies, and describe the design of two interaction strategies for constructing and manipulating such diagrams through this approach. A comparative study that we conducted with sighted users showed that a non-guided strategy allowed for significantly faster interaction times, and that both strategies supported similar levels of diagram comprehension. Overall, the reported study revealed that using multiple perspective hierarchies to structure the information encoded in a relational diagram enabled users construct and manipulate such information through an audio-only interface, and that combining aspects from the guided and the non-guided strategies could support greater usability.
