本研究探讨视障人士的资讯寻求行为，以进一步了解使用者使用网络资源的行为。使用的样本20视力和20视力障碍的人，用户进行了相同的四个信息寻求任务，使用四种不同的电子资源。结果证实，视障用户完成搜索和浏览任务需要更长的时间，时间因网站的设计而异。总的来说，视障用户在每个页面上花费更多的时间进行导航，特别是当页面包含大量信息或有许多链接时。观察显示，那些使用屏幕阅读技术的人往往发现搜索网络比那些有视力的人要困难得多，可以使用屏幕放大或近距离阅读屏幕。对他们使用的辅助技术有更多经验的人也更成功地完成了任务，这给用户和培训师都提出了培训问题。所使用的辅助技术的类型也对搜索过程有影响，更先进的功能为用户提供了更灵活的搜索方法。Jenny曾参与大英图书馆和JISC资助的电子图书馆视障用户资源（REVIEL）项目，该项目探索了图书馆OPAC和其他电子图书馆服务的无障碍性。她还领导了一个支持研究残疾和信息系统在高等教育（DISinHE）调查的认识和使用的无障碍设计标准在英国高等教育libraris.致谢作者承认的财政支持资源：理事会博物馆，档案馆和图书馆，使诺瓦项目进行。如果没有视力正常和视力受损的志愿者愿意贡献时间和精力，就不可能进行这项研究。我们非常感谢他们所有人。任何错误或遗漏，当然，完全是我们的责任。
The information seeking behaviour of visually impaired people has been explored in this study to develop further understanding of user behaviour with web based resources. Using a sample of twenty sighted and twenty visually impaired people, users undertook the same four information seeking tasks using four different electronic resources. Results confirmed that it takes visually impaired users longer to complete searching and browsing tasks, with times varying considerably depending on the design of the site. Overall, visually impaired users spend more time navigating around each page, especially if, for example, the page contains a lot of information or has many links. Observations revealed that those using screen reading technology tended to find searching the web much harder than those who had some sight and could use screen magnification or read a screen at close proximity. People with more experience with the assistive technology they were using were also more successful with the task, which raises training issues both for users and trainers. The type of assistive technology used also had a bearing on the search process-the more advanced features offering the user a more flexible approach to searching. Jenny has worked on the British Library and JISC funded REsources for Visually Impaired users of the Electronic Library (REVIEL) project which explored the accessibility of library OPACs and other electronic library services. She has also led a supporting study for Disability and Information Systems in Higher Education (DISinHE) which investigated awareness and use of accessibility design standards in UK higher education libraries.Acknowledgements The authors acknowledge the financial support of Resource: the Council for Museums, Archives and Libraries which enabled the NoVA project to be undertaken. Without the willing contribution of time and effort of our sighted and visually-impaired volunteers it would not have been possible to undertake this research. We are extremely grateful to them all. Any errors or omissions are, of course, entirely our responsibility.
