This career plan focuses on the broad challenges of designing every-citizen interfaces (ECIs) to the National Information Infrastructure (NII) and fully integrating individuals with disabilities into the education and employment mainstream. These are complementing challenges as full access to the NII is becoming integral to not only education and employment, but also leisure time pursuits. Access is of particular concern to individuals with physical, sensory, and other disabilities who often find current interfaces difficult or impossible to use. This career plan consists of a tightly coordinated set of research, education, and mentoring activities designed to address the NII interface and educational needs of individuals with disabilities.Within the broad objectives, the specific research activities of this plan focus on the development of rendering algorithms that will allow individuals with visual impairments access to multidimensional data through haptic and tactile means. Information that is multidimensional, such as complex mathematical expressions or recorded sensor data, is generally displayed in an inaccessible visual form. While tactile and haptic hardware technology continues to advance and can be brought to bear on this problem, relatively little research has been applied to the development of rendering algorithms for the effective display of information. This research will address the following fundamental issues: Optimal data decomposition for low-relief tactile and dynamic haptic display - Methods for extracting data features, including edges, contours, region boundaries, and textures that faithfully represent the underlying data will be developed. Optimal feature and multiresolution display - Display methods that are optimized for the low tactile and kinesthetic bandwidth will be developed. These methods will present data features in a form that can be comprehended tactilely and haptically. Moreover, these display methods will allow for a multiresolution display in which detail level can be easily controlled.The tactile and haptic rendering research will also develop multimodal methods and formalize this area of research borrowing from the more developed fields of sonification and general visualization.The research objectives are closely integrated with a complementing set of education and mentoring objectives, including the development of related courses and the implementation of mentoring activities for students from underrepresented groups in the high school through graduate school levels. The specific educational and mentoring objectives include: Course Development - Courses will be developed that give students a theoretical foundation in areas critical to ECI design and will also introduce them to a wide array of problems, including disability related issues. Students will also work with community organizations to solve real-world problems and learn in a problem-based setting. Mentoring activities - Mentoring activities include an Internet based mentoring program for high school students with disabilities, summer internships and research opportunities, and advisement of a campus disability issues focused student organization.The education and mentoring activities will be conducted in conjunction with the research activities, for instance through the use of research projects as teaching examples in courses and the inclusion of interns in research teams. Moreover, results from the research efforts will form new paradigm teaching tools that can be integrated into the curriculum. Through these coordinated efforts, the body of knowledge on ECI design will be advanced as will the opportunities available to individuals with disabilities.

该职业计划侧重于设计每个公民与国家信息基础设施（NII）的接口（ECIs）以及将残疾人充分融入教育和就业主流的广泛挑战。这些都是相辅相成的挑战，因为充分获得国家信息基础设施不仅是教育和就业的一部分，而且也是闲暇时间的追求。对于身体、感官和其他残疾的人来说，访问是一个特别重要的问题，他们经常发现当前的界面很难或不可能使用。该职业计划包括一系列紧密协调的研究、教育和指导活动，旨在解决NII接口和残疾人的教育需求。在广泛的目标范围内，该计划的具体研究活动侧重于开发渲染算法，使视觉障碍者能够通过触觉和触觉手段访问多维数据。多维信息，例如复杂的数学表达式或记录的传感器数据，通常以不可访问的视觉形式显示。虽然触觉和触觉硬件技术不断进步，可以带来承担这个问题，相对较少的研究已被应用到开发的渲染算法，有效地显示信息。这项研究将解决以下基本问题： 低浮雕触觉和动态触觉显示的最佳数据分解-提取数据特征的方法，包括边缘，轮廓，区域边界和纹理，忠实地代表底层数据将被开发。 优化功能和多分辨率显示-将开发针对低触觉和动觉带宽进行优化的显示方法。这些方法将数据特征以一种可理解和可感知的形式呈现出来。此外，这些显示方法将允许多分辨率显示，其中细节水平可以容易地控制。触觉和触觉渲染研究还将开发多模态方法，并从更发达的发声和通用可视化领域借用这一研究领域。研究目标与一套补充教育和指导目标紧密结合，包括为高中至研究生院阶段代表性不足群体的学生开设相关课程和开展辅导活动。具体的教育和辅导目标包括： 课程开发-课程将开发，让学生在ECI设计的关键领域的理论基础，也将向他们介绍了广泛的问题，包括残疾相关的问题。学生还将与社区组织合作，解决现实世界的问题，并在基于问题的环境中学习。 指导活动-指导活动包括为残疾高中生提供基于互联网的指导计划，暑期实习和研究机会，以及建立一个以校园残疾问题为重点的学生组织。教育和指导活动将与研究活动一起进行，例如，通过利用研究项目作为课程中的教学实例，以及将实习生纳入研究小组。此外，研究工作的结果将形成新的范式教学工具，可以融入课程。通过这些协调一致的努力，将推进关于出口信用保险设计的知识体系，并为残疾人提供机会。
