当屏幕读取器用户需要返回跟踪页面以重新找到先前访问的内容时，他们被迫聆听每个不需要的页面的某些部分以识别它。这使听觉后导航效率低下，尤其是在大型网站上。为了解决这个问题，我们介绍了基于主题和列表的背面：两种导航策略，通过利用内容丰富的网站的概念结构来提供浏览快捷方式。两者都体现在WebTime，这是网络历史上的一个可访问的网站。一项在印第安纳州盲人学校进行的对照研究（n = 10）比较了基于主题和列表的背部与传统背部机制，而参与者完成了事实调查任务。基于主题和列表的背部大大减少了任务和回溯页的数量；导航捷径还与感知的认知工作和导航经验的积极改善有关。拟议的策略可以作为补充信息丰富的网站中当前的背部机制的补充。
When screen reader users need to back track pages to re-find previously visited content, they are forced to listen to some portion of each unwanted page to recognize it. This makes aural back navigation inefficient, especially on large websites. To address this problem, we introduce topic- and list-based back: two navigation strategies that provide back browsing shortcuts by leveraging the conceptual structure of content-rich websites. Both are manifested in Webtime, an accessible website on the history of the Web. A controlled study (N=10) conducted at the Indiana School for the Blind and Visually Impaired compared topic- and list-based back to traditional back mechanisms while participants completed fact-finding tasks. Topic- and list-based back significantly decreased time-on-task and number of backtracked pages; the navigation shortcuts were also associated with positive improvements in perceived cognitive effort and navigation experience. The proposed strategies can operate as a supplement to current back mechanisms in information-rich websites.
