This application seeks further support for the development of a wayfinding system specifically for building interiors of the facilities of public accommodations (e.g. office buildings, transportation facilities, hospitals, etc.) that will increase accessibility of those facilities to visually impaired users and serve as an environmental rehabilitative intervention for vision loss. This computerized system, called Pathfinder, interacts with users using artificial speech, voice recognition, electronic tactile touch tablet, and a high contrast visual CRT display. Embodying principles of universal design and intended to be useful for all users, including fully-sighted, the system will also increase accessibility for wheelchair users and hearing-impaired persons. Phase I results demonstrated feasibility with blind users unfamiliar with one floor of a Manhattan office building, and showed that the system is capable of training users with no experience with visual or tactile maps on its use without human intervention. Phase II research will address further development of the physical design of the product, the user training module, the tactile and voice recognition interfaces, and the visual display for low vision. Additionally, computer programming tools for building map and signage design professionals will be developed and tested. The product, along with an instructional package will be commercialized in Phase III.

该应用程序寻求进一步支持开发 专门用于设施建筑内部的寻路系统 公共设施（例如办公楼、交通 设施、医院等），这将增加这些设施的可及性 为视障用户提供设施并作为环境 视力丧失的康复干预。 这个计算机化系统， 称为 Pathfinder，使用人工语音与用户交互 识别、电子触觉触摸板和高对比度视觉 CRT显示器。体现通用设计原则并旨在 对所有用户（包括视力正常的用户）都有用，该系统还将 增加轮椅使用者和听力障碍人士的无障碍环境 人。 第一阶段的结果证明了盲人用户的可行性 不熟悉曼哈顿办公楼的一层，并显示 该系统能够培训没有经验的用户 无需人工干预即可使用的视觉或触觉地图。 第二阶段 研究将解决物理设计的进一步发展 产品、用户培训模块、触觉和语音识别 界面和低视力视觉显示。 此外， 用于构建地图和标牌设计的计算机编程工具 将培养和测试专业人​​员。 该产品，连同 教学包将在第三阶段商业化。
