Abstract

People who are blind use screen readers for browsing web pages. Since screen readers read out content serially, a naive readout tends to mix irrelevant and relevant content thereby disrupting the coherency of the material being read out and confusing the listener. To address this problem we can partition web pages into coherent segments and narrate each such piece separately. Extant methods to do segmentation use visual and structural cues without taking the semantics into account and consequently create segments containing irrelevant material. In this paper, we describe a new technique for creating coherent segments by tightly coupling visual, structural, and linguistic features present in the content. A notable aspect of the technique is that it produces segments with little irrelevant content. Preliminary experiments indicate that the technique is effective in creating highly coherent segments and the experiences of an early adopter who is blind suggest that it enriches the overall browsing experience.
紧密耦合的视觉和语言功能,丰富基于音频的网页浏览体验
盲人使用屏幕阅读器浏览网页。由于屏幕阅读器是连续读出内容的,幼稚的读出往往会把无关的和相关的内容混在一起,从而破坏所读出的材料的连贯性,使听者感到困惑。为了解决这个问题,我们可以将网页划分成连贯的片段,并分别叙述每个片段。现有的分割方法使用视觉和结构线索,而不考虑语义,从而创建包含不相关材料的片段。在本文中,我们描述了一种通过内容中存在的视觉、结构和语言特征紧密耦合来创建连贯片段的新技术。该技术的一个值得注意的方面是,它产生的片段几乎没有无关的内容。初步实验表明,该技术在创建高度连贯的片段方面是有效的,而早期盲人用户的体验表明,它丰富了整体的浏览体验。
