目前，对于视力受损的人来说，访问数字存储的数值数据非常有限。图形和可视化通常用于分析数值数据之间的关系，但当前访问它们的方法是高度视觉化的。使用音频反馈表示数据是使数据更易于访问的常见方法，但导航和访问数据的方法通常是串行的且费力的。触觉显示器可用于提供额外的反馈，以支持视障人士的点击式交互。与视力受损的计算机用户进行的需求捕获对当前的辅助技术进行了审查，并提取了使用触觉反馈来辅助导航的指南。还介绍了原型界面的定性评估结果。提供绝对位置输入设备和触觉反馈允许用户以类似于点击技术的方式使用触觉和本体感觉线索来探索图形。
Access to digitally stored numerical data is currently very limited for sight impaired people. Graphs and visualizations are often used to analyze relationships between numerical data, but the current methods of accessing them are highly visually mediated. Representing data using audio feedback is a common method of making data more accessible, but methods of navigating and accessing the data are often serial in nature and laborious. Tactile or haptic displays could be used to provide additional feedback to support a point-and-click type interaction for the visually impaired. A requirements capture conducted with sight impaired computer users produced a review of current accessibility technologies, and guidelines were extracted for using tactile feedback to aid navigation. The results of a qualitative evaluation with a prototype interface are also presented. Providing an absolute position input device and tactile feedback allowed the users to explore the graph using tactile and proprioceptive cues in a manner analogous to point-and-click techniques.
