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（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者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，并有效地到达每个网页的所需部分。这项努力的动机是对一个人了解 网页是该计算机用户人群面临的最大挑战之一。现有的盲人和视力障碍人员的工具，例如屏幕读取器和屏幕放大器，通过详细信息的文本输出串行详细介绍整个网页，或者提供了该页面一小部分的放大视图。但是，如果用户尚未熟悉该网站，则缺乏上下文需要一个费力且耗时的过程来扫描有时数百个细节，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，拟议的技术以类似的方式分析了网页，目击者在详细阅读之前迅速扫描页面，以提供有关页面上下文和布局的简洁，有益的指导，以便用户迅速获得了更丰富的“大型图片”的理解。拟议的II期项目基于成功的I阶段用户对该软件的证明的评估，在该证明中，用户对方法提供了强烈的偏爱。第二阶段包括创建软件工具的彻底功能原型。在整个技术开发中，用户和从业人员的反馈将指导研发的道路，以提供最大的可用性。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，为全尺度商业化提供了起点。
