DESCRIPTION (provided by applicant): Screen readers (computer applications that display screen text and icons in speech or an on-line mechanical braille display) can give blind people good access to standard text in many computer applications. We propose to develop an affordable on-line Accessible Graphics Reader (AGR) to provide comparable access to graphical information. AGR will give excellent access to graphical information presented in well-structured, labeled Scalable Vector Graphic (SVG) format. SVG is a new World Wide Web markup language: SVG authoring programs are already available that permit one easily to create graphical information that is universally usable in principle. The AGR will make those graphics easily accessible in practice to blind people, including those who do not read braille. AGR consists of a high-resolution embosser integrated with a touch pad permitting blind people to emboss and feel tactile graphics and hear (or read with an on-line braille display) names and descriptions of important objects in the graphic. Any text included with the graphic can be heard in speech or displayed in braille. Sections of the graphic may be selected, expanded, and re-printed at will. The critical components of a more general "AGR interactive print viewer" software application will be created also. It will emboss information from any Windows application that has the ability to print. It will then permit users to interact with that tactile printout and optimize any graphics. The AGR interactive viewer also gives access to text that may be hard to read with a screen reader. The research is successful if AGR provides access to SVG. The commercial market is considerably enhanced if the AGC Viewer application can be created also. AGR and its associated software promotes rehabilitation of computer-literate blind people by providing improved access to education and professional opportunity. A second generation AGC integrated with a talking e-book reader could give user-friendly text and graphic access even to elderly or computer-phobic blind users.

描述（由申请人提供）：屏幕读取器（在语音或在线机械盲文显示中显示屏幕文本和图标的计算机应用程序）可以使盲人在许多计算机应用程序中良好地访问标准文本。我们建议开发负担得起的在线访问图形读取器（AGR），以提供对图形信息的可比访问。 AGR将以结构良好的标记可伸缩矢量图形（SVG）格式提供出色的图形信息。 SVG是一种新的世界网络标记语言：SVG创作程序已经可用，可以轻松地创建原则上普遍使用的图形信息。 AGR将使这些图形在实践中很容易访问盲人，包括那些不读盲文的人。 AGR由一个高分辨率的压花器组成，该压力器与触摸垫集成，允许盲人可以浮雕和感觉到触觉图形，并听到（或在线盲文显示屏上读取（或读取）图形中重要对象的名称和描述。图形中包含的任何文本都可以在语音中听到或以盲文显示。可以选择，扩展和重新打印图形的部分。还将创建更通用的“ AGR交互式印刷查看器”应用程序的关键组件。它将从任何具有打印功能的Windows应用程序中提出信息。然后，它将允许用户与该触觉打印输出进行交互并优化任何图形。 AGR Interactive查看器还可以访问屏幕读取器可能很难阅读的文本。如果AGR提供对SVG的访问，则该研究将成功。如果也可以创建AGC查看器应用程序，商业市场将大大增强。 AGR及其相关的软件通过提供改进的教育和专业机会来促进计算机识字盲人的康复。与会说话的电子书阅读器集成的第二代AGC甚至可以为老年人或计算机盲人用户提供用户友好的文本和图形访问。
