众所周知，许多网页很难被视力残疾人和使用小屏幕设备的人使用。在这两种情况下，都存在着观看大量信息的问题，其显示能力从预期的格式化大屏幕彩色显示器降低。然而，有必要问一下，在标准显示器上显示网页如何使视力正常的人更容易使用。为了开始回答这个问题，我们报告了一项探索性的眼动追踪研究，该研究调查了视力正常的读者如何使用BBC新闻网页的呈现来搜索链接。我们比较了标准的页面呈现与“纯文本”版本，并观察到定性和定量的预期演示文稿的删除改变“阅读”的行为。信息的呈现有助于任务完成的演示表明，如果Web要变得更容易访问，则应重新引入非视觉呈现。最后，我们建议，模型来自研究，揭示如何演示文稿是用来帮助完成任务，可以形成的基础上，注释和转码的网页，目前的网页在一个更有用的非视觉形式。
It is well known that many Web pages are difficult to use by both visually disabled people and those who use small screen devices. In both cases there exists a problem of viewing a great deal of information with presentation capabilities reduced from the intended formatted large-screen colour display. It is pertinent, however, to ask how the presentation of Web pages on a standard display makes them easier for sighted people to use. To begin to answer this question, we report on an exploratory eye-tracking study that investigates how sighted readers use the presentation of the BBC News Web page to search for a link. We compare the standard page presentation with a "text-only" version and observe both qualitatively and quantitatively that the removal of the intended presentation alters "reading" behaviours. The demonstration that the presentation of information assists task completion suggests that it should be re-introduced to non-visual presentations if the Web is to become more accessible. Finally, we propose that models derived from studies that reveal how presentation is used to aid task completion can form the basis for annotation and transcoding of Web pages to present pages in a more usable non-visual form.
