移动的应用程序中的可访问性问题使许多人难以或无法访问这些应用程序。示例包括无法为屏幕阅读器提供替代文本的元素、难以导航的顺序或使关键功能无法访问的自定义小部件。社会注释技术已经证明了引人注目的方法,这种可访问性的关注,在网络上,但一直难以应用在移动的应用程序,因为强大的注释接口的挑战。本研究开发了移动的应用程序界面元素的鲁棒注释方法。设计用于运行时接口修改,我们的方法是基于屏幕标识符,元素标识符,和屏幕等效语法。我们实现初始开发工具注释移动的应用程序的可访问性元数据,评估我们目前的屏幕等价物在从50个移动的应用程序收集的2038个屏幕的数据集中,提出了三个案例研究实现常见的可访问性问题的运行时修复,并检查修复现实世界中的可访问性问题26个应用程序。这些贡献总体上展示了移动的可访问性中的社会注释的强大机会。
Accessibility issues in mobile apps make those apps difficult or impossible to access for many people. Examples include elements that fail to provide alternative text for a screen reader, navigation orders that are difficult, or custom widgets that leave key functionality inaccessible. Social annotation techniques have demonstrated compelling approaches to such accessibility concerns in the web, but have been difficult to apply in mobile apps because of the challenges of robustly annotating interfaces. This research develops methods for robust annotation of mobile app interface elements. Designed for use in runtime interface modification, our methods are based in screen identifiers, element identifiers, and screen equivalence heuristics. We implement initial developer tools for annotating mobile app accessibility metadata, evaluate our current screen equivalence heuristics in a dataset of 2038 screens collected from 50 mobile apps, present three case studies implementing runtime repair of common accessibility issues, and examine repair of real-world accessibility issues in 26 apps. These contributions overall demonstrate strong opportunities for social annotation in mobile accessibility.
