本文质疑我们如何能够和应该目前图表盲人使用计算机生成的声音。使用一次只显示图的一部分而不是全部信息的系统会导致两个问题。第一个问题是如何提供信息，使用户能够将信息整合成一个连贯的整体。二是如何选择要呈现的区域。这是通过使用一个系统来观察的，该系统呈现代表中央供暖系统原理图的图形。该系统通过信息和导航系统的分层分离或信息和导航系统的面向连接的分离来由用户选择呈现信息。此外，我们有一个分裂，是否使用一个简单的系统来呈现节点的位置。任务，被分类为基于层次信息或基于连接的信息，使用该系统设置和不同的模型的效果被记录。发现任务与导航系统匹配，但是位置呈现没有可辨别的效果。
This paper questions how we could and should present diagrams to blind people using computer-generated sound. Using systems that present information about one part of the diagram at a time, rather than the whole, leads to two problems. The first problem is how to present information so that users can integrate the information into a coherent overall picture. The second is how to select the area to be presented. This is looked at by using a system that presents graphs representing central heating system schematics. The system presents information by user choice through either a hierarchical split of information and navigation system, or a connection oriented split of information and navigation system. Further, we have a split as to whether a simple system of presenting location of nodes is used, or not. Tasks, classified as being based on hierarchical information or connection-based information, were set using the system and the effect of the different models was recorded. It was found that there was a match of task to navigation system, but that presentation of position had no discernable effect.
