DESCRIPTION (provided by applicant): The purpose of this SBIR project is to develop a new tool to improve the ability of blind and visually impaired people to quickly get to the right web pages, to avoid ending up on the wrong web pages, and to reach the desired part of the web page efficiently. The motivation for this project is that getting a 'big picture' understanding of a web page is one of the biggest challenges facing visually impaired computer users. Although tools such as screen readers currently exist to convert the text on web pages to audible speech, this solves only a small part of the problem. Existing tools for the visually impaired present the entire web page serially, in full detail, and if the user is not already familiar with the website, it requires a laborious and time- consuming process to read through sometimes hundreds of text objects before knowing whether anything of interest even exists on the page in question. In contrast, the proposed technology analyzes web pages and provides a succinct, informative synopsis of the context of the text and layout of the page, so that a user quickly gains an understanding of where relevant information can be found on the page. The proposed Phase I project involves working with users and instructors to verify the concept, creation of proof-of-concept software to perform the above analysis, and an end-user evaluation study to verify that the new tool, designed to work in conjunction with a market-leading screen reader, improves their abilities and confidence in Internet browsing. PUBLIC HEALTH RELEVANCE: The R&D in this Phase II SBIR project will result in an improved way to use the Internet for individuals with visual disabilities. The technology will help to overcome the lack of accessibility and high level of frustration currently found among blind and visually impaired users. The results of the project will enable such individuals to explore new opportunities and be more productive, thus providing improved employment potential and an increase in the quality of life.

描述（由申请人提供）：该SBIR项目的目的是开发一种新工具，以提高盲人和视力障碍的人快速进入正确的网页的能力，以避免在错误的网页上最终进入错误的网页，并有效地到达网页的所需部分。该项目的动机是，对网页获得“大图”的理解是视力受损的计算机用户面临的最大挑战之一。尽管目前存在诸如屏幕读取器之类的工具来将网页上的文本转换为可听见的语音，但这仅解决了问题的一小部分。视障人士的现有工具串行整个网页详细介绍了整个网页，如果用户尚未熟悉该网站，则需要一个费力且耗时的过程才能阅读有时会读取数百个文本对象，然后才知道该页面上是否存在任何感兴趣的东西。相比之下，所提出的技术分析了网页，并提供了页面文本和布局的简洁，信息性的概述，以便用户很快就可以了解页面上可以找到相关信息的地方。提出的I阶段项目涉及与用户和讲师合作验证概念，创建概念验证软件以执行上述分析，以及一项最终用户评估研究，以验证该新工具旨在与市场领先的屏幕读取器结合使用，从而提高了他们的互联网浏览能力和信心。 公共卫生相关性：此II阶段SBIR项目的研发将导致一种改进的视觉残障人士使用互联网的方法。该技术将有助于克服目前在盲人和视力障碍用户中发现的缺乏可及性和高水平的挫败感。该项目的结果将使此类人能够探索新的机会并提高生产力，从而提供改善的就业潜力并提高生活质量。
