DESCRIPTION (provided by applicant): Screen readers (computer applications that display screen text and icons in speech or an online mechanical braille display) can give blind people good access to standard text in many computer applications. In Phase I research we have demonstrated the feasibility of an Accessible Graphics Reader (AGR) that can provide comparable access to more complex information. In Phase II we propose to build a manufacturable prototype of the AGR with design features intended to expand its market significantly and hence to be more affordable by blind people. AGR will have a touch pad that attaches to a "color embosser" - a printer with an embossing head and a color ink jet head. A tactile color image rolls out onto the touch pad permitting users to feel the document, select any part to enlarge, change tactile brightness and contrast, and reprint if desired. Text objects can be voiced with a speech engine (or displayed with an on-line Braille display) when touched. AGR will give good access to all graphical materials that are either already in electronic form (e.g. the internet) or can be scanned from paper copy. It gives particularly good access to graphical information presented in well-structured, labeled Scalable Vector Graphic (SVG) format. The labels in these files can be accessed by touch, making even very complex graphics very accessible. SVG is a new World Wide Web markup language, and ViewPlus is working with the Web Access Initiative to define graphics accessibility guidelines that would assure that SVG files will be authored to be very accessible by AGR. The proposed AGR includes a color ink jet head so that it will promote rehabilitation of a broad group of people with disabilities by providing improved access to education and professional opportunity. This group includes people with low vision, dyslexia and other learning disabilities, a market segment that could be a thousand times the number of people who are totally blind. If integrated with a user-friendly talking e-book or network reader AGR could extend user-friendly text and graphic access even to elderly or computer-phobic 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。在第一阶段的研究中，我们证明了可访问的图形读取器（AGR）的可行性，该读取器（AGR）可以提供对更复杂信息的可比访问。 在第二阶段，我们建议建立一个可制造的AGR制造原型，其设计功能旨在大大扩展其市场，因此使盲人更负担得起。 AGR将有一个触摸垫，该垫子连接到“彩色压花”上 - 带有压花头和彩色墨水头的打印机。 触觉颜色图像将触摸板推出，允许用户感觉文档，选择放大的任何零件，更改触觉亮度和对比度，并根据需要重印。 触摸时，可以用语音引擎（或在线盲文显示屏显示）配音文本对象。 AGR将很好地访问已经以电子形式（例如互联网）或可以从纸质副本扫描的所有图形材料。 它特别良好地访问了以结构良好的标记可扩展矢量图形（SVG）格式显示的图形信息。 这些文件中的标签可以通过触摸访问，甚至非常复杂的图形也非常容易访问。 SVG是一种新的万维网标记语言，ViewPlus正在使用Web访问计划来定义图形可访问性指南，该指南将确保将撰写SVG文件，以通过AGR非常访问。拟议的AGR包括一个彩色墨水喷气式头，以便通过改善获得教育和专业机会的机会来促进一群残疾人的康复。该小组包括低视力，阅读障碍和其他学习障碍的人，这是一个完全失明的人数的一千倍的市场领域。 如果与用户友好的电子书或网络阅读器AGR集成，则甚至可以将用户友好的文本和图形访问扩展到老年人或计算机用户。
