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 each web page efficiently. The motivation for this effort is that getting a 'big picture' understanding of a web page is one of the biggest challenges facing this population of computer users. Existing tools for blind and visually impaired people, such as screen readers and screen magnifiers, present the entire web page serially, in full detail, either by textual output of the details, or b providing a magnified view of a small part of the page. However, if the user is not already familiar with the website, the resulting lack of context requires a laborious and time-consuming process to scan through sometimes hundreds of details before knowing whether anything of interest even exists on the page in question. In contrast, the proposed technology analyzes web pages in a similar way that sighted users quickly scan pages before reading in detail, to provide a succinct, informative guidance on the context and layout of the page, so that a user quickly gains a much richer "big-picture" understanding. The proposed Phase II project builds on a successful Phase I user evaluation of a proof- of-concept of the software, in which users expressed a strong preference for the contextual cues provided by the approach. Phase II includes creating a fully-functional prototype of the software tool. Throughout the technology development, feedback from users and practitioners will guide the path of the R&D for maximum usability. At the conclusion of Phase II, an end-user, in-home evaluation study will verify the effectiveness of the tool, providing the starting point for full-scale commercialization.

描述(申请人提供)：该SBIR项目的目的是开发一种新的工具，以提高盲人和视障人士快速访问正确网页的能力，避免最终出现在错误的网页上，并有效地到达每个网页的所需部分。这一努力的动机是为了对一个 网页是这群计算机用户面临的最大挑战之一。现有的盲人和视障人士工具，如屏幕阅读器和屏幕放大镜，通过以文本形式输出细节，或b提供页面一小部分的放大视图，连续、完整地呈现整个网页。然而，如果用户还不熟悉网站，则所产生的缺乏上下文需要费力和耗时的过程来扫描有时数百个细节，然后才能知道所讨论的页面上是否存在感兴趣的东西。相比之下，拟议的技术以类似的方式分析网页，即有视力的用户在详细阅读之前快速扫描页面，以提供关于页面上下文和布局的简明、信息丰富的指导，从而使用户迅速获得更丰富的“大背景”理解。拟议的第二阶段项目建立在第一阶段用户对软件概念验证的成功评价的基础上，其中用户对该方法提供的背景线索表现出强烈的偏好。第二阶段包括创建软件工具的全功能原型。在整个技术开发过程中，用户和从业者的反馈将指导研发实现最大可用性。在第二阶段结束时，最终用户的家庭评估研究将验证该工具的有效性，为全面商业化提供起点。
